Speed up load by eliminating document.write

I've been profiling FCKeditor with Firebug to see if I can improve its load time. The construction of all of the FCKPanel's in the default sample takes 100ms in Firefox, and it can be reduced to 50ms by eliminating the document.write (see patch).

I did notice #515, which may prove this approach to be unusable.

To provide a point of reference, this change takes the total JavaScript time from 250ms to 200ms (20% less).

Apologies. It looks like this patch is completely broken. You cannot set the document's HTML by setting oIFrame.src via JavaScript.

comment:3 Changed 17 years ago by Matthias Miller

Clarification: Setting an IFRAME's HTML using the src property is asynchronous, which breaks many assumptions regarding FCKPanel.

Most probably the synchronous behavior of document write is making that function a bit slower, but as you have noted we need the iframe DOM ready for interaction right after its creation.
