I´m using SS2.4 with the RemodelAdmin (http://www.leftandmain.com/uncategorized/2011/02/25/taming-the-beast-remodeling-modeladmin/) for the project, I´m working on.

When you open an entry in RemodelAdmin to edit some values, an javascript should run if you change the value in an inputfield, something like that:

$('#Form_EditForm_Foo').on('keydown', function(){
//Do something
});

I´ve tried to use in the ModelAdmin class:

Requirements::javascript('foo/foo.js');

and the javascript is called correctly and it works perfectly for the search inputfields on the left for example,
but I can't figure out how to get it works for the right side.

I know that the javascript is loaded too soon to make things on the right side after I click on an entry,
but it must be possible to use javascript somehow?

firstly, check the source code to check the js file is actually loading...

if is it is, you'll need 'entwine' it. The example below is runs when the a custom model is openned... simply put, it waits for a div with the class NameOfMyCustomAdmin' to appear, then adds the javascript.

you'll have to set it up to connect with

(function($) {

  
    $(document).ready(function(){
    
    $('.NameOfMyCustomAdmin').entwine({
      onmatch: function() {
        
        // do your stuff
        
      }
    });
        
    })
  
})(jQuery);

Great, this is it, now it works! Great thanks!
