I don't quite understand your issue but seeing as nobody even tries to help you here's my two cents:
It makes no sense to me having to pass a method from a window to another. "Windows" are only DOM objects with extended functionality and methods can exist outside of them, so I don't understand why you would "pass a Window A method to Window B". To me it should look like this:
<script type="text/javascript">
<!--
function DoSomething(param)
{
$("#data").text(param.val()); // "Cross window" action
}
-->
</script>
</head>
<body>
<div class="easyui-panel" style="position: relative; width: 100%; height: 650px; overflow: auto;">
<div id="win_a" class="easyui-window" data-options="title:'Window A',inline:true,closable:false" style="width: 500px; height: 200px; padding: 10px">
<div id="data"> </div>
<a href="javascript:void(0)" class="easyui-linkbutton" onclick="$('#win_b').window('open')">Edit</a>
</div>
<div id="win_b" class="easyui-window" data-options="title:'Window B',inline:true,closable:false,closed:true" style="width: 500px; height: 200px; padding: 10px">
<input class="easyui-textbox" type="text" name="data_in" id="data_in" data-options="required:true"></input>
<a href="javascript:void(0)" class="easyui-linkbutton" onclick="DoSomething($('#data_in')); $('#win_b').window('close')">Save</a>
</div>
</div>
the script holds the function that is being run when Window B is closed. So the workflow is
- Window A is open by default
- Press Button on Window A
- Button opens Window B
- Enter data in Window B
- Press Button on Window B
- Invoke (global) DoSomething() with the data field from Window B as parameter
- Close Window B
- DoSomething has updated a div on Window A to contain the value from the data field from Window B
What you defined in DoSomething will be executed when pressing the Button on Window B (the same code is usable for an OnClose event, however I haven't found any on EasyUI).
Again, I have no idea if this is even remotely close to what you were looking for. Please specify your problem a bit more so you can get more detailed help for your problem.
