Javascript loading on IE slower than Firefox

Copy linkTweet thisAlerts:
May 26.2007

Hi,

I have a page [URL=”http://blm.sis.pitt.edu:8080/ppiServiceInvoke2/opName/findPartnersWithinThresholdAndList_select.htm”]here [/URL] using Javascript to load several options into a <select> box. The javascript itself is in a separate file [URL=”http://blm.sis.pitt.edu:8080/ppiServiceInvoke2/opName/swap.js”]here[/URL] . The addOrfList(1) function in the body onload event calls the javascript to load the select box. There are about 6300 options to be loaded.

When I load this page into Firefox 1.5.0.11, it takes a second or two and loads fine. However, when I try to load it with IE 7.0.5730.11, it takes a few minutes to load.

I realize this is a lot of options but why does it work fine in Firefox and not IE?

Thanks in advance.

Cheers,

Chris

@FangMay 26.2007 — Try this:var thisCTRL=["YAL001C","YAL002W","YAL003W","YAL004W","YAL005C"]; // add reest of values to array;
//begin addOrfList
function addOrfList(inputArg)
{
var thisCtrl = document.myForm['input' + inputArg];
var i = 0, len = thisCTRL.length, opts = "";
while (i&lt;len) {
opts+='&lt;option value="'+thisCTRL[i]+'"&gt;'+thisCTRL[i++]+'&lt;/option&gt;';
}
thisCtrl.innerHTML=opts;
document.body.innerHTML = document.body.innerHTML; // IE update DOM
}

Test this with a small array first to check that option values are returned to the server.

Success!
