Description

On my webpage, I noticed that if i did something like this

$('myDropdown').attr('selectedIndex',3);

the dropdown position would not change; however

alert($('myDropdown').attr('selectedIndex'));

prints 3

To see the correct behavior try something like this:

document.getElementById('myDropdown').selectedIndex = 3;

which does change the dropdown position

use with

<form>
<select name="myDropdown" id="myDropdown">
<option value="a">a</option>
<option value="b">b</option>
<option value="c">c</option>
<option value="d">d</option>
<option value="e">e</option>
<option value="f">f</option>
</select>
</form>

Tested in Firefox 2.0.0.6

It looks like this bug is back again since jQuery 1.6.1.

Yep. It took me an hour of fiddling to finally realize that.

_comment0:	Most likely you are using `.attr()` instead of `.prop()`. → 1314379781414770

Most likely you are using .attr() instead of .prop(). There is no *attribute* named selectedIndex so the code above is invalid.

Using .prop doesn't change anything, still doesn't work.

You Can get Selected index like this

$('myDropdown').get(0)('selectedIndex',3);

When using an asp.net dropdownlist (<asp:DropDownList), when I tried to set a selectedIndex on the dropdownlist using the above example, it does not work.

I have declare the asp:dropdownlist object as

$("#<%=ddlCity.ClientID %>").get(0)('selectedIndex',3);
