Select an option of select box using the value

Question

I have a dropdown box and I want to select the option based on value. Somehow I am getting handle to value say 3. Now I want to manually select the option which has got value 3.

I have tried something like this

selectBoxElement.options[selectedValues].selected = true;

where selectedValue = 3, but it is not working.

If using jquery (as per your tag), you can do:

$(document).ready(function() {
  $("#yourSelectId option[value='3']").attr("selected", "selected");
});
