Why does on change not trigger in this example?

Question

The call to start() should trigger the change

$(function () {
    $('#ddlTo').on("change", function () {
        $("#div1").html($(this).val());
    })

    start();
});

function start() {
    $('#ddlTo').val("master");
}

Another proof that some SO people are very harsh on newcomers with poor English. — mplungjan, Mar 03 '13 at 11:23

Your question isn't entirely clear, but my guess is you'd like to fire the change event when you initialise the value of the select.

This should do what you expect:

$('#ddlTo').val("master").change();

The change event only fires when the user initiates the change.

Assuming you and I both understood the question, then your answer now definitely answers it :) – mplungjan Mar 03 '13 at 11:28

As alnorth29 pointed out, your question is not clear but maybe this is what you want:

http://jsfiddle.net/txqed/3/

$('#ddlTo').on("change", function() {
    $("#div1").html($(this).val());
    start();
});

Basically changing the select box back to "master" after displaying user selected value.

Edit: I misunderstood your question. As pointed out in the comments this behavior is not very logical.

That would not be logical in any way I can imagine – mplungjan Mar 03 '13 at 11:25
