Check to see if a cfwindow exists

Check to see if a cfwindow exists
When a window gets created by <cfwindow> coldfusion gives it a unique name and not the name you assigned it.
I have found a work around in the way of checking for the title of the window as when you create a cfwindow the window title div get the id of yourwinname_title.

(code)

Example javascript
<cfajaximport tags="cfwindow"/>
<script language="javascript">
function createphloadwin() {
if(document.getElementById('mywindow_title')) {
var x = "true";
// Show the window
ColdFusion.Window.show("mywindow");
} else {
var x = "false";
// Create a new window
ColdFusion.Window.create("mywindow", "Upload Photos", "", {height:250,width:400,closable:true,draggable:true,resizable:false,center:true,initshow:true,modal:t rue })
// Put your content in the window or you can assign the url in the ColdFusion.Window.create()
document.getElementById('mywindow_body').innerHTML = 'My Window content';
}
alert(x);
}
</script>

<a href="javascript:createphloadwin();">Check for window</a>

I don't know if CF does things differently when it creates the CFWINDOW, but can't you just use the window_name.close() feature to close it? Then you should also be able to check if window is open with some JS. If (window_name) then windown_name.close; //checks if the window exists, and if it does, it closes it.

Hi Ebot,

thanks for the reply

This JS script is to check to see if the cfwindow has been pre-created. As I explained you can't ref a cfwindow by the name assigned to it in the cfwindow tag via JS there is no CFAJAX or CFJS functions to do this. Hence the work around. This has nothing to do with showing and hiding windows there are cf JS functions to do that. If you have an app that creates windows dynamically and you use the cfwindows tag you will end up with a new window every time you hit the same button CF wont destroy and recreate the window.
