val() doesn't trigger change() in jQuery [duplicate]

Answer 1

I know this is an old thread, but for others looking, the above solutions are maybe not as good as the following, instead of checking change events, check the input events.

$("#myInput").on("input", function() {
    // Print entered value in a div box
    $("#result").text($(this).val());
});

Answer 2

From redsquare's excellent suggestion, this works nicely:

$.fn.changeVal = function (v) {
    return this.val(v).trigger("change");
}

$("#my-input").changeVal("Tyrannosaurus Rex");

Answer 3

No you might need to trigger it manually after setting the value:

$('#mytext').change();

or:

$('#mytext').trigger('change');
