HTMLEditor Control Raise any Client-Side Events 

 

The HTML Editor has three modes: Design, HTML Text, and Preview mode.

 

The design mode is in an IFrame. HTML Text is presented in a TextArea and the preview mode is in another Iframe. The code rendered about these three modes is as below:

<iframe id="editor1_ctl02_ctl00" name="editor1_ctl02_ctl00" marginheight="0" marginwidth="0" frameborder="0" src="javascript:false;" style="height:100%;width:100%;display:none;border-width:0px;">
/iframe>

<textarea id="editor1_ctl02_ctl01" class="ajax__htmleditor_htmlpanel_default" style="height:100%;width:100%;display:none;">
/textarea>

<iframe id="editor1_ctl02_ctl02" name="editor1_ctl02_ctl02" marginheight="0" marginwidth="0" frameborder="0" src="javascript:false;" style="height:100%;width:100%;display:none;border-width:0px;">
/iframe>

In the design mode, we can use the following JavaScript to append a callback function in onKeypress event.

< script type = "text/javascript" >
 var count = 0;
function pageLoad() {
 $get('editor1_ctl02_ctl00').contentWindow.document.body.onkeypress = function() {
  count++;
  $get('cc').innerHTML = "you input " + count + "charactors";
 };
}
/script>

In the same way, you can append another keypress event on the TextArea and preview IFrame.
