I have a dropdown list with more than one thousand items. Once I click on clear button it should clear all items. For removing I tried looping.

What would be the fastest way to remove all items from a dropdown list or listbox?

Reset to default 8

Set innerHTML of select box as empty string.

var selectBox = document.getElementById("selectboxID");
selectBox.innerHTML = "";

An option if you're using jQuery:

$("#selectboxID").empty();

Thanks for the quick reply How about this?? document.getElementById(id).options.length = 0;
