Couple of days back, while implementing JQuery I had requirement of adding item to the drop down list after an AJAX Call. This is very simple when we talk about Asp.net AJAX but in Jquery you by yourself need to handle many things at the client end. Anyway, that’s how it works.
var ddl = document.getElementById("ddlOptions");
var myoption = document.createElement("option"); //works with both mozilla and IE
myoption.text = $("MyText",this).text();
myoption.value = $("MyValue",this).text(); //Probably, the ID stuff
ddl.options.add(myoption);
I am sure the classic asp gurus must have great idea about this.
