Hi! I have some scripting foo where I add some element dynamically and the want to query the width of it.
NOTE: The reason I want width is for centering. If anyone knows a way to center a DIV element without knowing its width, just say so and the below problem is irrelevant. (same goes for height and vertical centering) It is more or less like this: $(top.document.body).append("<div id='TB_window'></div>"); // inject a LINK element into top.document for a CSS file then append some stuff into TB_window, // marker 1 then call $("#TB_window",top.document).width() If I put an alert() at "marker 1" before the width() call, I get different results than without. It seems Firefox (v3.5.3) takes the opportunity while the alert is displayed to compute some stuff, which makes the width() result correct. If I don't use alert(), then width() returns s smaller value (about 30% less) than the real one. Funny, in IE8 there is no such problem. There the correct width is reported. I use JQuery 1.3.2. I put the entire code at http://pastie.org/658921 it is called from HTML by a href="#" onclick="tb_show('#TB_inline? height=332&width=590&inlineId=lb_content&modal=false', (this.rel || false),'/stuff/css');return false;" PopupboxNM /a (I removed brackets in case they give problems to mail/ web programs) Regards, David
