Can an expert tell me what the following asp.net ajax jscript code does?
SInce I can't find a javascript or an ASP.NET AJAX forum here (Why???), I guess this is the best place to ask an ASP.NET AJAX javascript question! ;-)
I hope an expert can comment the following scriptlet of javascript code (from the ajax htmleditor control in AjaxControlToolkit), and tell me what's going on. I haven't a clue, mainly because of the prominent regex.
500 pts to the expert that can answer the question! Thanks.

checkState : function() {
if(!AjaxControlToolkit.HTMLEditor.ToolbarButton.FontName.callBaseMethod(this, "checkState")) return false;

var param =null;
try{param = (Function.createDelegate(editor, AjaxControlToolkit.HTMLEditor._queryCommandValue))("fontname");} catch(e){}
if(!editor._FontNotSet)
if(!param || param.length==0) {
param = AjaxControlToolkit.HTMLEditor.getStyle(editor._doc.body,"font-family");
}
var el = this._select;
var i=0;
if(param && param.length > 0) {
var seek = param.toLowerCase().split(",")[0].replace(/^(['"])/,"").replace(/(['"])$/,"");
for(i=0; i< el.options.length; i++) {
var cur = el.options.item(i).value.toLowerCase().split(",")[0];
if(cur==seek) break
}
if(i==el.options.length) {
try {
var newopt = document.createElement("OPTION");
newopt.value = param.replace(/^(['"])/,"").replace(/(['"])$/,"");
newopt.text = param.split(",")[0].replace(/^(['"])/,"").replace(/(['"])$/,"");
el.add(newopt,(AjaxControlToolkit.HTMLEditor.isIE)?i:null);
$addHandler(newopt, "click", this._onclick_option$delegate);
} catch(e) {
i = 0;
}
}
}
el.selectedIndex = i;

Hey mark:
Well, I'm hoping to hear from an expert at some point, but you're on the right track I think. However, what does the whole second part of the code do? What's going on w/the loop w/the 'OPTION' element stuff?

Thanks! Sorry...my dad is ill and it's been hard to keep track of these things...
I think this is a bit of code to avoid SQL injection into your database. Or validating the input against characters not allowed and removing them out of the input.
But i am not a java specialist.
