Limit text in CKEDITOR

6

I'm trying to make a character limiter in CKEditor, but I did not find any way, the script I used to limit <textarea> does not work when I'm using CKEDITOR.

I tried to use the wordcounter plugin which now seems to only count, does not limit .

extraPlugins: 'wordcount',
                wordcount: {
                    showCharCount: true,
                    showWordCount: false,
                    charLimit: 7500
                }

Does anyone know of a script? what limits?

There is a plugin for CKEditor itself for the purpose of limiting the number of characters entered:

CKEditor Maxlength Plugin ( English)

Here are the steps to implement the same:

  • Edit the file config.js and add the following:

    config.extraPlugins = 'maxlength';
    

    The result will be something like this:

    CKEDITOR.editorConfig = function( config ) {
    
      // Define changes to default configuration here.
      // For the complete reference:
      // http://docs.ckeditor.com/#!/api/CKEDITOR.config
    
      config.extraPlugins = 'maxlength';
    
    };
    
  • In textarea add one of the following two attributes maxlength="xxx" or data-maxlen="xxx" to something like this:

    <textarea rows="5" name="ola" id="ola" cols="120" data-maxlen="255"></textarea>
    
  • You can download the plugin from .

    PlugIn Code

    In PlugIn comments, a user complained about an error regarding the use of hasAttr() . Just in case the plugin does not use this method:

        var plugin = CKEDITOR.plugins.maxlength;
    
        function doCharacterCount(evt) {
            var editor = evt.editor;
            if ($('span#cke_maxlength_' + editor.name).length > 0) { // Check element exists
                setTimeout(function () {
                    var charCount = editor.getData().length;

        });
    })();
    
    // Plugin options
    CKEDITOR.config.max_length = 0;
    

    Save to a file named plugin.js that should be in a folder named maxlength .

    The wordcount plugin of the ckeditor has a parameter that limits the number of characters.

    Resolve the problem as follows:

    showCharCount: true,
    maxCharCount: 10 
    

    Replace 10 with the amount of characters you need.

    Follow the link to the plugin's documentation: wordcount documentation
