Question

I have seen other posts here at SO about this very same subject, but I have not found a solution that is setting the select using jQuery.

I have a dropdown that looks like this:

<select type="select" id="docsList" name="docsList"> 
    <option id="defaultListItem" value="0">Select a Document...</option> 
    <option value="38">Document 1</option> 
    <option value="35">Document 2</option> 
    <option value="46">Document 3</option> 
    <option value="45">Document 4</option>          
</select>

I need to reset the dropdown within an $.ajax() success function. I’ve used the following:

$('select#docsList option:selected').val('0');
$('select#docsList').attr('selectedIndex', 0);

… and some others.

I’m beginning to think this code is fine and I’ve got something else going on preventing resetting the dropdown.

Answer 1

You’re overcomplicating things. You don’t need jQuery to get/set a <select>‘s selectedIndex.

$('#docsList').get(0).selectedIndex = 0;

When setting the value of a <select>, call .val() on the <select>, not on one of its <option>s.

$('#docsList').val('0');
