使用javascript获取ckeditor textarea的textarea值

Question

I'm a learner as far as JS goes and although I've spent a good few hours reading through tutorials which has helped lots but I'm still having problems figuring out exactly how I find out what a user is typing into a ckeditor textarea.

What I'm trying to do is have it so that when someone types into the textarea, whatever they type appears in a div in a different part of the page.

I've got a simple text input doing that just fine but because the text area is a ckEditor the similar code doesn't work.

I know the answer is here: ckEditor API textarea value but I don't know enough to figure out what I'm meant to do. I don't suppose anyone fancies helping me out?

The code I've got working is:

$('#CampaignTitle').bind("propertychange input", function() {
  $('#titleBar').text(this.value);
});

and

<label for="CampaignTitle">Title</label>
<input name="data[Campaign][title]" type="text" id="CampaignTitle" />

and

<div id="titleBar" style="max-width:960px; max-height:76px;"></div>

I'm still having problems figuring out exactly how I find out what a user is typing into a ckeditor textarea.

Ok, this is fairly easy. Assuming your editor is named "editor1", this will give you an alert with your its contents:

alert(CKEDITOR.instances.editor1.getData());

The harder part is detecting when the user types. From what I can tell, there isn't actually support to do that (and I'm not too impressed with the documentation btw). See this article: http://alfonsoml.blogspot.com/2011/03/onchange-event-for-ckeditor.html

Instead, I would suggest setting a timer that is going to continuously update your second div with the value of the textarea:

timer = setInterval(updateDiv,100);
function updateDiv(){
    var editorText = CKEDITOR.instances.editor1.getData();
    $('#trackingDiv').html(editorText);
}

This seems to work just fine. Here's the entire thing for clarity:

<textarea id="editor1" name="editor1">This is sample text</textarea>

<div id="trackingDiv" ></div>

<script type="text/javascript">
    CKEDITOR.replace( 'editor1' );

    timer = setInterval(updateDiv,100);
    function updateDiv(){
        var editorText = CKEDITOR.instances.editor1.getData();
        $('#trackingDiv').html(editorText);
    }
</script>

Answer 2

At least as of CKEDITOR 4.4.5, you can set up a listener for every change to the editor's contents, rather than running a timer:

CKEDITOR.on("instanceCreated", function(event) {
    event.editor.on("change", function () {
        $("#trackingDiv").html(event.editor.getData());
    });
});

I realize this may be too late for the OP, and doesn't show as the correct answer or have any votes (yet), but I thought I'd update the post for future readers.

Answer 3

Simply execute

CKEDITOR.instances[elementId].getData();

with element id = id of element assigned the editor.

Answer 4

You could integrate a function on JQuery

jQuery.fn.CKEditorValFor = function( element_id ){
  return CKEDITOR.instances[element_id].getData();
}

and passing as a parameter the ckeditor element id

var campaign_title_value = $().CKEditorValFor('CampaignTitle');

Answer 5

i found following code working for ckeditor 5

ClassicEditor
    .create( document.querySelector( '#editor' ) )
    .then( editor => {
        editor.model.document.on( 'change:data', () => {
            editorData = editor.getData();
        } );
    } )
    .catch( error => {
        console.error( error );
    } );

Answer 6

Well. You asked about get value from textarea but in your example you are using a input. Anyways, here we go:

$("#CampaignTitle").bind("keyup", function()
{
    $("#titleBar").text($(this).val());
});

If you really wanted a textarea change your input type text to this

<textarea id="CampaignTitle"></textarea>

Hope it helps.

Answer 7

you can add the following code : the ckeditor field data will be stored in $('#ELEMENT_ID').val() via each click. I've used the method and it works very well. ckeditor field data will be saved realtime and will be ready for sending.

$().click(function(){
    $('#ELEMENT_ID').val(CKEDITOR.instances['ELEMENT_ID'].getData());
});

Answer 8

var campaignTitle= CKEDITOR.instances['CampaignTitle'].getData();
