UI Dialog causing iframe to reload content every time 'show' is called

[bgrinstead]

I recently ran into this problem. Basically, if you have an iframe inside your dialog content, every time you reshow the dialog, it reloads the iframe. This is unexpected and incorrect behavior. I have tracked down the change in the open function:

(uiDialog.next().length && uiDialog.appendTo('body'));

This line works - the iframe does not reload because the DOM is not being manipulated, I guess?

(uiDialog.parent().not('body').length && uiDialog.appendTo('body'));

Note: I found the fix here: ​http://www.nabble.com/-jquery.ui.dialog--Dailog-with-a-lot-of-HTML-unbearably-slow-td21257084s27240.html

Please take a look at this!

Thanks, Brian Grinstead

I experienced the same issue in Firefox.

I changed this code:

(uiDialog.next().length && uiDialog.appendTo('body'));

To:

if (uiDialog.next().length && uiDialog.get(0).parentNode != document.body) {

uiDialog.appendTo('body');

}

• This may fix #4589 too.
• #4534 is similar to #3012.
