Jquery to retrieve and set selected index value of html select element

Question

I am attempting to retrieve and set the selected value of a select element (drop down list) with Jquery.

for retrievel i have tried $("#myId").find(':selected').val(), as well as $("#myId").val() but both return undefined.

Any insight into this problem would be much appreciated.

thanks in advance

Answer 1

$('#myId').val() should do it, failing that I would try:

$('#myId option:selected').val()

Answer 2

It looks like your selector $("#myId") is not correct. Are you sure there is a select element with id="myId" ?

Answer 3

The way you have it is correct at the moment. Either the id of the select is not what you say or you have some issues in the dom.

Check the Id of the element and also check your markup validates at here at W3c.

Without a valid dom jQuery cannot work correctly with the selectors.

If the id's are correct and your dom validates then the following applies:

To Read Select Option Value

$('#selectId').val();

To Set Select Option Value

$('#selectId').val('newValue');

To Read Selected Text

$('#selectId>option:selected').text();

Answer 4

$("#myId").val() should work if myid is the input select element id!

This would set the selected item: $("#myId").val('VALUE')
