Fire jquery event when a new dropdown value gets set

Question

I have 2 options in the dropdown.

<select id="_fid_140" onchange="chooseRecordPicker()" >
<option value="736">9000000146</option>
<option value="x3recpcker#">&lt; Browse choices... &gt;</option>

After clicking on Browse choices, a new window opens, I make a selection there, I hit save. The options in the dropdown change to

 <option value="740">9000000140</option>
 <option value="x3recpcker#">&lt; Browse choices... &gt;</option>

I want an event to be fired after "a new value has been set" in the dropdown.

Answer 1

$('select').change(function(){
    //Run your function here. 
});

This function will run when the dropdown menu selected option has been changed.
