If you have a select element that looks like this:

JavaScript

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

Running this code:

JavaScript

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:

JavaScript

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

Which would make strUser be test2
