Am unable to add elements to a dropdown list via Javascript.
The below piece of code works in IE and Chrome, but not in firefox.
ddlId.add(new Option("",0));
In firefox, I keep getting an 'Not enough arguments' exception. Any idea on how to resolve it? Thanks
try {
ddlId.add(new Option("",0), null); // standards compliant; doesn't work in IE
} catch(ex) {
ddlId.add(new Option("",0)); // IE only
}
Hm. The idea is, roughly, to go to the Mozilla Developer Center page for select.add() and have a look at the method signature ;-)
Syntax
select.add(newOption, existingOption);Parameters
newOption
An HTMLOptionElement to add to the options collection.existingOption
An existing HTMLOptionElement within the collection used as a reference point for inserting the new element; the new element being inserted before the referenced element in the collection. If this parameter is null, the new element is appended to the end of the collection.
var opt = document.createElement("option");
var ddlPopulate=document.getElementById("<%=ddlPopulate.ClientId %>");
opt.text="firstElement";
opt.value="1";
ddlPopulate.options.add (opt);
The select element has as its children an options array. You add or remove options as you would using standard array methods.
