javascript - Hijack a CKeditor input field -

i want able grab onfocus event url text input field when pulls image dialog box in ckeditor.

i tried adding event handler element (id #cke_75_textinput) it's in dom after image button has been clicked.

having looked through ckeditor 3 javascript api documentation , here, struggling , couldn't find needed.

is can done through api?

there's no need magic focus delegation (which mess since focus not bubble). use ckeditor api:

ckeditor.on( 'dialogdefinition', function( evt ) {     if ( evt.data.name == 'image' ) {         var def = evt.data.definition;          var onshow = def.onshow;         def.onshow = function() {             onshow && onshow.apply( this, arguments );              var input = this.getcontentelement( 'info', 'txturl' );             console.log( input.getvalue() );             input.on( 'focus', function() {                 console.log( 'focused' );             } );         };     } } ); 

ps. cke4's docs more handful old cke3's - http://docs.ckeditor.com/#!/api/ckeditor.dialog
