How to add ASP DropDown values through javascript?

Question

I am using a asp drop down list. According to my requirement I need to set the values of that drop down list through external java script file. How is it possible? I will not use document object to get the drop down Id.

what do you mean by asp drop down list? are you using asp.net mvc? — Sandeep G B

Remember that in all likelihood, ASP.NET will not detect the new options correctly on a postback – listControl.Items should only contain items you add in code-behind or that are restored from ViewState. You'll have to figure out which items are selected some other way. (E.g. directly from the HTTP request.) — millimoose

Also, what do you mean by "I will not use document object to get the drop down Id."? And are you using jQuery or not? That is, is it okay for the answer to be jQuery based or would you prefer plain Javascript? — millimoose

If you can set up the list of option values as a js array then you can use jQuery's $.each method to build the dropdown like this

HTML

<select id="drop"></select>

JQuery

var values = ['test1','test2','test3','test4','test5','test6'];

$.each(values,function(i,val){
   $('<option />').text(val).val(val).appendTo('#drop');
});
