## Get started

### Installation

Via a package manager
`npm install trumbowyg` `bower install trumbowyg`
or
Download the package
Download

If you don't already do it, load jQuery at bottom of `<body>` like so:

    <script src="//ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
    <script>window.jQuery || document.write('<script src="js/vendor/jquery-3.2.1.min.js"><\/script>')</script>

Trumbowyg requires jQuery >= 1.8

After these lines, you have to load Trumbowyg.

    <script src="node_modules/trumbowyg/dist/trumbowyg.min.js"></script>

Don't forget to load Trumbowyg CSS in the `<head>`, or load your own style for the editor.

    <link rel="stylesheet" href="node_modules/trumbowyg/dist/ui/trumbowyg.min.css">

### Basics

This the minimal code to transform a simple div into the amazing WYSIWYG editor which is Trumbowyg.

    $('#trumbowyg-demo').trumbowyg();

If you want to set options to Trumbowyg, add an object which contains your options as parameters.

    $('#trumbowyg-demo').trumbowyg({
        btns: ['strong', 'em', '|', 'insertImage'],
        autogrow: true
    });

### Common issues

#### SVG icons does not load

- check if you are in HTTP(S) protocol;
- check if you do not have cross domain error (XHR request is used).

If your problem is not solved by these tips, check the SVG icons section.

### Use plugins

#### Add a plugin to your page

Basically you need to add the plugin JS to your page, at the bottom of your `<body>`, after jQuery and Trumbowyg imports (in this order), but before your custom JS which initialize Trumbowyg:

    <-- Import jQuery -->
    <script src="//ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
    <script>window.jQuery || document.write('<script src="js/vendor/jquery-3.2.1.min.js"><\/script>')</script>

    <-- Import Trumbowyg -->
    <script src="node_modules/trumbowyg/dist/trumbowyg.min.js"></script>

    <-- Import Trumbowyg plugins... -->
    <script src="node_modules/trumbowyg/dist/plugins/upload/trumbowyg.cleanpaste.min.js"></script>
    <script src="node_modules/trumbowyg/dist/plugins/upload/trumbowyg.pasteimage.min.js"></script>

    <-- Init Trumbowyg -->
    <script>
        // Doing this in a loaded JS file is better, I put this here for simplicity
        $('#my-editor').trumbowyg();
    </script>

In the previous case, plugins are "auto registering" themself into Trumbowyg and be activated in all future Trumbowyg instances.

But most popular plugins are button-based, like upload or colors ones. If you want to use these plugins, load them like explained before, then add the plugin button to your editor by checking the button pane doc section.

For more informations on plugins, check the plugins documentation page.

## General

### Prefix

You can change prefix of all class added on elements of Trumbowyg using this option:

    $('textarea').trumbowyg({
        prefix: 'custom-prefix'
    });

For example, the bold button class is now `custom-prefix-bold-button`

Default value is `trumbowyg`

### Localization

Your users don't speak english? No problem, Trumbowyg has a language parameter. You have to load the appropriate lang file. Search in `/dist/langs` folder to see if a language file already exists, if not create it and share it :). See add a localization for more details on language file.

Don't forget include the lang file in your pages:

    <script type="text/javascript" src="js/dist/langs/fr.min.js"></script>

Warning, include lang file after Trumbowyg and before instantiating the editor!

Usage of language parameter:

    $('textarea').trumbowyg({
        lang: 'fr'
    });

If the lang was not found, english values are used by default.

### Custom skin

Trumbowyg is flexible and simple. You want a different look?

#### Replace existing CSS file

Copy `/src/ui/` folder somewhere and customize style. Finally, link your new CSS file and remove link to Trumbowyg default style.

It is not recommended to directly edit the CSS file in the trumbowyg folder. When you update the plugin, your modifications will be erased.

#### Multiple skins for multiple Trumbowyg

This is useful when you do not want same design for all instances of Trumbowyg.

Use the prefix option:

    $('.editor-modern-ui').trumbowyg({
        prefix: 'modern-ui'
    });

In your CSS, you can now stylize `.modern-ui-link-button` for example, whitout conflicts with the default skin. It's necessary to redefine style for all elements. If you want to start from the default skin, copy `/src/ui/` folder, replace all `trumbowyg-` by your prefix and work from here.

### SVG icons

Added in 2.1.0

A pack of SVG icons is available and enabled by default. This file is loaded via XHR request in JavaScript so it is possible the path is not matching with your assets file paths. You can change the path of the SVG or disable this feature.

#### Change SVG path globally

To change SVG path, you need to set the path in global Trumbowyg configuration object:

    $.trumbowyg.svgPath = '/assets/my-custom-path/icons.svg';

This global way needs to be done before initialize any Trumbowyg instance.

#### Disable SVG icons globally

If you do not want SVG icons, you can set this option to false. Then, you can add your custom icons by CSS or what you want.

    $.trumbowyg.svgPath = false:

Check hide button texts option if you did not want button content at all and customize it by yourself.

This global way needs to be done before initialize any Trumbowyg instance.

#### Change SVG path or disable SVG icons locally

You can also apply `svgPath` option for an isolated editor only.

    $('.editor').trumbowyg({
        svgPath: false // or a path like '/assets/my-custom-path/icons.svg'
    });

#### Use SVG icons without XHR or via an another protocol than HTTP(S)

If you want to be IE9-complient you should use this option.

If you do not want use HTTP(S) protocol or use XHR to load icons, you can load icons in your HTML by your own. You just need to include the icons.svg file inline in your `<body>`:

    <div id="trumbowyg-icons">
        <svg xmlns="http://www.w3.org/2000/svg">
            <symbol id="trumbowyg-blockquote" viewBox="0 0 72 72"><path d="..."></path></symbol>
            <symbol id="trumbowyg-bold" viewBox="0 0 72 72"><path d="..."></path></symbol>
            <symbol id="trumbowyg-close" viewBox="0 0 72 72"><path d="..."></path></symbol>
            <!-- ... all other icons here -->
        </svg>
    </div>

You need to use this id: `<prefix>-icons`.

Trumbowyg check if a `#<prefix>-icons` exists. If not, it loads SVG icons file via XHR and put it in a div with this id. Next editor on the page do not load icons again. By adding this div in the page, you "hack" this mecanism to load it by your own.

### Placeholder

Like the HTML5 attribute on input and textarea, you can add a placeholder with Trumbowyg.

    <div class="my-editor" placeholder="Your text as placeholder"></div>

Placeholder is visible only if the element is empty (no HTML/text).

Placeholder is both managed in JS and CSS with the default style. If you create your own style, you need to apply the following style (replace `trumbowyg` by your prefix):

    .trumbowyg-editor[contenteditable=true]:empty::before{
        content: attr(placeholder);
        color: #999;
    }

### Disabled

Added in 2.1.0

Trumbowyg supports `disabled` attribute on a textarea and an option.

    <textarea class="my-editor" disabled></textarea>

    $('.a-disabled-editor').trumbowyg({
        disabled: true
    });

You can switch between disabled and enabled states by using API

## Basic Options

### Button pane

It's probably the most interesting option, it allows you to choose the buttons that appears in the button pane. This option is an array containing string values representing the buttons or vertical separators (using the pipe character). To create your own custom button pane, define an array and pass it to the `btns` option.

    $('.simple-editor').trumbowyg({
        btns: [['bold', 'italic'], ['link']]
    });

By default, `btns` option value is:

    $('.simple-editor').trumbowyg({
        btns: [
            ['viewHTML'],
            ['undo', 'redo'], // Only supported in Blink browsers
            ['formatting'],
            ['strong', 'em', 'del'],
            ['superscript', 'subscript'],
            ['link'],
            ['insertImage'],
            ['justifyLeft', 'justifyCenter', 'justifyRight', 'justifyFull'],
            ['unorderedList', 'orderedList'],
            ['horizontalRule'],
            ['removeformat'],
            ['fullscreen']
        ]
    });

### Hide button texts

Added in 2.5.0

You can hide button texts showed when you put svgPath to false.

    // Globally
    $.trumbowyg.hideButtonTexts = true

    // Or locally
    $('.trumbowyg').trumbowyg({
        hideButtonTexts: true
    });

If you disable SVG icons and button texts, you should design them by yourself.

### Semantic

Generates a better, more semantic oriented HTML (i.e. `<em>` instead of `<i>`, `<strong>` intsead of `<b>`, etc.). It's just a boolean:

    $('.trumbowyg').trumbowyg({
        semantic: false
    });

This option deactivates the underline button by default because they do not convey any real semantic. If you want to reactivate them, you have to do it explicitly, see Button pane

This option is set to `true` by default

### Reset CSS

If you don't want the page style to impact on the look of the text in the editor, you will need to apply a reset-css on the editor. You can activate this with the `resetCss` option:

    $('.trumbowyg').trumbowyg({
        resetCss: true
    });

This option is set to `false` by default. The reset only applies to the editor, not to the generated HTML code.

### Remove format pasted

If you don't want styles pasted from clipboard (from Word or other webpage for example), pass the `removeformatPasted` option to `true`

    $('.trumbowyg').trumbowyg({
        removeformatPasted: true
    });

In order to use this option, you need to define a font size in your CSS or use a reset like normalize.

Remove format pasted is not active by default (set to `false`).

### Auto grow

The text editing zone can extend itself when writing a long text. To activate this feature, use the autogrow option:

    $('.trumbowyg').trumbowyg({
        autogrow: true
    });

Autogrow is not active by default (set to `false`).

### Auto grow on enter

Added in 2.7.0

The text editing zone can extend itself when editor get focus and reduce on blur. To activate this feature, use the following option:

    $('.trumbowyg').trumbowyg({
        autogrowOnEnter: true
    });

Autogrow on enter is not active by default (set to `false`).

### Image width modal edit

Added in 2.9.0

Add a field in image insert/edit modal which allow users to set the image width. To activate this feature, use the following option:

    $('.trumbowyg').trumbowyg({
        imageWidthModalEdit: true
    });

Image width modal edit is not active by default (set to `false`).

### URL protocol

Added in 2.9.4

An option to auto-prefix URLs with a protocol.

When this option is set to `true`, URLs missing a protocol will be prefixed with `https://`. Alternatively, a string can be provided for a custom prefix.

For example, a value of `true` would convert `example.com` to `https://example.com`, while a value of `ftp` converts to `ftp://example.com`.

    $('.trumbowyg').trumbowyg({
        urlProtocol: true
    });

Anchors, email addresses and relative links are left unchanged.

URL protocol is not active by default (set to `false`).

### Minimal links

Added in 2.9.4

Reduce the link overlay to use only `url` and `text` fields, omitting `title` and `target`.

    $('.trumbowyg').trumbowyg({
        minimalLinks: true
    });

The minimal links option is not active by default (set to `false`).

## Advanced Options

### Add a localization

The structure of a language file is simple, it is a JavaScript Object which associate a translation to any key. For example:

    jQuery.trumbowyg.langs.fr = {
        _dir: "ltr", // Changes the editor dir

        bold: "Gras",
        close: "Fermer"
    };

Some localizations are added each day, you can find them in the langs folder on GitHub

You can submit a new localization file by creating a new pull request on the Github repository.

English is the default localization, you don't need to include any file to get Trumbowyg in English.

### Custom buttons

If Trumbowyg does not fit your needs, maybe you can create your very own custom button to solve this. The following code (which does not works as is) show you all available button parameters.

    $('.trumbowyg').trumbowyg({
        btnsDef: {
            buttonName: {
                fn: 'functionName',
                tag: 'tagName',
                title: 'Button tooltip',
                text: 'Displayed button name',
                isSupported: function () { return true; },
                key: 'K',
                param: '' ,
                forceCSS: false,
                class: '',
                hasIcon: true
            }
        }
    });

The key (here `buttonName`) is the button name used in `btns` and in `dropdown`. It is used as many default in options below.

                fn: function() {
                    alert('some text')
                },
                ico: 'blockquote'
            }
        },
        btns: [
            ['alert']
        ]
    });

### Custom dropdowns

You can also create your own dropdown, like buttons. The following code (which does not works as is) show use all options which can be used to make our own customized dropdown.

    $('.trumbowyg').trumbowyg({
        btnsDef: {
            dropdownButtonName: {
                dropdown: ['btnA', 'btnB'],
                title: 'Displayed dropdown button name',
                ico: 'iconName',

                ico: 'justifyLeft'
            }
        },
        btns: [
            ['align']
        ]
    });

## API

### Modal box

When you want create your custom extension for Trumbowyg, you can open and close a modal box with custom inner HTML code, listen events and more.

#### Open and close

For that use the `.trumbowyg()` method and give parameters `'openModal'` or `'closeModal'` like that:

    // Open a modal box
    var $modal = $('#editor').trumbowyg('openModal', {
        title: 'A title for modal box',
        content: '<p>Content in HTML which you want include in created modal box</p>'
    });

    // Close current modal box
    $('#editor').trumbowyg('closeModal');

An `openModal` call returns a jQuery object which contains the modal box. You need this object if you want to use listen events (see below).

Only one modal box can open at any given moment. So, `openModal` return false if a modal is curently opened.

#### Events on modal box

Modal boxes in Trumbowy come with two buttons: "Confirm" and "Cancel". An event is associated to each one:

- `tbwsubmit`: trigged when form is submit
- `tbwreset`: trigged when user cancel operation

    // Open a modal box
    var $modal = $('#editor').trumbowyg('openModal', {
        title: 'A title for modal box',
        content: '<p>Content in HTML which you want include in created modal box</p>'
    });

    // Listen clicks on modal box buttons
    $modal.on('tbwconfirm', function(e){
        // Save datas
        $("#editor").trumbowyg('closeModal');
    });
    $modal.on('tbwcancel', function(e){
        $('#editor').trumbowyg('closeModal');
    });

#### Only build inputs in modal

If you want only add inputs in the modal box, this function is more simple. Indeed, you do not manage confirm and close buttons, and get all input value on confirm.

    var img = $('img#an-img');
    $("#editor").trumbowyg('openModalInsert', {
        title: 'A title for modal box',
        fields: {
            url: {
                value: img.attr('src')
            },
            alt: {
                label: 'Alt',
                name: 'alt',
                value: img.attr('alt'),
                type: 'text'.
                attributes: {}
            },
            example: {
                // Missing label is replaced by the key of this object (here 'example')
                // Missing name is the key
                // When value is missing, value = ''
                // When type is missing, 'text' is assumed. You can use all the input field types,
                //   plus checkbox and radio (select and textarea are not supported)
                // When attributes is missing, {} is used. Attributes are added as attributes to
                //   the input element.
                // For radio and checkbox fields, you will need to use attributes if you want it
                //   to be checked by default.        }
        },
        callback: function(values){
            img.attr('src', values['url']);
            img.attr('alt', values['alt']);

            return true; // Return true if you have finished with this modal box
            // If you do not return anything, you must manage the closing of the modal box yourself
        }
    });

    // You can also listen for modal confirm/cancel events to do some custom things
    // Note: the openModalInsert callback is called on tbwconfirm
    $modal.on('tbwconfirm', function(e){
        // Do what you want
    });
    $modal.on('tbwcancel', function(e){
        trumbowyg.closeModal();
    });

### Range

Managing correctly text range, is not so trivial. Trumbowyg has a system to save and restore selection range which does not involves typical getter/setter.

#### Save and get current range

    // Save current range
    $('#editor').trumbowyg('saveRange');

    // Restore last saved range
    $('#editor').trumbowyg('restoreRange');

#### Get selection range

    // range contains a JavaScript range
    var range = $('#editor').trumbowyg('getRange');

#### Get last saved range text

    var text = $('#editor').trumbowyg('getRangeText');

### Manage content

You can set and get current HTML content of the editor with a getter/setter:

    // Get HTML content
    $('#editor').trumbowyg('html');

    // Set HTML content
    $('#editor').trumbowyg('html', "<p>Your content here</p>");

### Empty

You can empty the content of the editor.

    $('#editor').trumbowyg('empty');

### Enable/disable edition

Added in 2.1.0

As you can disable editor by using disabled option, you can also switch between enabled and disabled states by using API.

    $('#editor').trumbowyg('disable');
    $('#editor').trumbowyg('enable');

### Toggle between HTML & WYSIWYG modes

Added in 2.9.0

You can switch between HTML view and WYSIWYG view via toggle method.

    $('#editor').trumbowyg('toggle');

### Destroy editor

When you wish, you can restore the previous state of the element was used to create the editor.

    $('#editor').trumbowyg('destroy');

### Events

Some events are fired on the jQuery element which is used to build the editor.

- Focus on editor: `tbwfocus`
- Blur on editor: `tbwblur`
- Editor is initialized: `tbwinit` 2.0.0
- Change in editor: `tbwchange` 2.0.0
- Resize the editor on autogrow: `tbwresize` 2.0.0
- Paste something in the editor: `tbwpaste` 2.0.0
- Switch to fullscreen mode: `tbwopenfullscreen` 2.0.0
- Leave editor's fullscreen mode: `tbwclosefullscreen` 2.0.0
- Close the editor: `tbwclose` 2.0.0

    $('#editor')
    .trumbowyg() // Build Trumbowyg on the #editor element
    .on('tbwfocus', function(){ console.log('Focus!'); }); // Listen for `tbwfocus` event
    .on('tbwblur', function(){ console.log('Blur!'); }); // Listen for `tbwblur` event
