JAVASCRIPT

get the value or text from select element using 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:

var e = document.getElementById("ddlViewBy");
var strUser = e.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;

// element.setSelectionRange(start, end, ?direction)
// start, end - start and end indices of the new selection
// direction (optional) - "forward", "backward", or "none" (default)
element.setSelectionRange(3, 5);
