jQuery Cleditor wysiwyg text editor: keyup() works in webkit browsers but not Firefox or IE

问题

I'm trying to follow up on a previous Stackoverflow question about how to display content from a Cleditor textbox in an external HTML element such as a <p>. Here's the question and the fiddle which solves my problem in webkit browsers but not Firefox or IE:

Here's the code from the fiddle:

<textarea id="input" name="input"></textarea>
<p id="x"></p>  

<script>
  $("#input").cleditor();

  $(".cleditorMain iframe").contents().find('body').bind('keyup',function(){
    var v = $(this).text(); // or .html() if desired
    $('#x').html(v);
  });
</script>

I've read Get content of iframe from jquery that I need to use "window.top.... to access the main page and pass it that way because .contents() is not supported by all browsers" but i'm not sure how to use window.top for this purpose and am hoping someone might be able to shed some light on this topic.

回答1:

The cleditor documentation states that it does have a "change" event which it claims to work with the 'keyup' event, but unfortunately in my testing it didn't work as expected with Firefox 7 (requires clicking out of the text-editor).

Jsfiddle: http://jsfiddle.net/qm4G6/27/

Code:

var cledit = $("#input").cleditor()[0];

cledit.change(function(){
    var v = this.$area.context.value;
    $('#x').html(v);
});

There is also another StackOverflow question which asked about the same thing, in which user Ling suggests modifying the plugin to add your own function: Get content from jquery CLEditor

Edit: Based on your comments with the above SO question result's not working, I've amended the code below. This works in IE9 and IE9's "IE8" developer mode. http://jsfiddle.net/qm4G6/80/

$(document).ready(function(){

 var cledit = $("#inputcledit").cleditor()[0];
 $(cledit.$frame[0]).attr("id","cleditCool");

var cleditFrame;
if(!document.frames)
{
   cleditFrame = $("#cleditCool")[0].contentWindow.document;
}
else
{
    cleditFrame = document.frames["cleditCool"].document;
}

$( cleditFrame ).bind('keyup', function(){
    var v = $(this).text(); 
    $('#x').html(v);
});

});

Another Edit: To get the HTML, you have to find body within the iframe like $(this).find("body").html(). See the code below. JSFiddle: http://jsfiddle.net/qm4G6/84/

var cledit = $("#inputcledit").cleditor()[0];
$(cledit.$frame[0]).attr("id","cleditCool");

var cleditFrame;
if(!document.frames)
{
   cleditFrame = $("#cleditCool")[0].contentWindow.document;
}
else
{
    cleditFrame = document.frames["cleditCool"].document;
}

$( cleditFrame ).bind('keyup', function(){
        var v = $(this).find("body").html();
        $('#x').html(v);
});

$("div.cleditorToolbar, .cleditorPopup div").bind("click",function(){
      var v = $( cleditFrame ).find("body").html();
      $('#x').html(v);
});

Since I answered the question that prompted you for this, I guess I'll answer this one too ;)

This works in Chrome and Firefox (I don't have access to IE):

$("#input").cleditor();

$( $(".cleditorMain iframe")[0].contentWindow.document ).bind('keyup', function(){
    var v = $(this).text(); // or .html() if desired
    $('#x').html(v);
});

Updated jsFiddle

UPDATE

This also works in Chrome and Firefox. Maybe IE too?

$("#input").cleditor();

$( $(".cleditorMain iframe")[0].contentDocument ).bind('keyup', function(){
    var v = $(this).text(); // or .html() if desired
    $('#x').html(v);
});
