Javascript Question

Get selected value in dropdown list using JavaScript?

How do I get the selected value from a dropdown list using JavaScript?

I tried the methods below but they all return the selected index instead of the value:

var as = document.form1.ddlViewBy.value;
var e = document.getElementById("ddlViewBy");
var strUser = e.options[e.selectedIndex].value;

//This is one of the simplest form by (Narendra Kottamidde) :

var value = document.getElementById("ddlViewBy").value;

Answer

If you have a select element that looks like this:

<select id="ddlViewBy">
  <option value="1">test1</option>
  <option value="2" selected="selected">test2</option>
  <option value="3">test3</option>
</select>

Running this code:

var e = document.getElementById("ddlViewBy");
var strUser = e.options[e.selectedIndex].value;

Would make strUser be 2. If what you actually want is test2, then do this:

var e = document.getElementById("ddlViewBy");
var strUser = e.options[e.selectedIndex].text;

Which would make strUser be test2
