Hi,
I’m wondering if this is standard functionality but if I replace a group of selects with jqxDropDownList then I cannot set the change event (or select) by using a group selector like a class. Same things happens with jqxComboBox.
Sample code:
$(“.prop_type”).on(“change”, function (event) {
//Do something here
});Is there a workaround?
Thanks,
DirkI kind of found a workaround but I don’t really like it.
$(“.jqx-widget”).each(function () {
if ($(this).attr(“role”) == “combobox”) {
$(this).on(“change”, function (event) {
// Do things
});
};
});If someone has a better way, please let me know.
Thanks!
Hi Dirk,
There is a simpler workaround, presented in the following example:
<!DOCTYPE html> <html lang="en"> <head> <link rel="stylesheet" href="../../jqwidgets/styles/jqx.base.css" type="text/css" /> <script type="text/javascript"

http://www.jqwidgets.com/Thanks Dimitar. Good that there is a better workaround but wouldn’t it even be better if it worked with the assigned class? Following default Jquery practices?
Hi Dirk,
Unfortunately, this cannot currently be achieved, because of the way the dropdownlist (and combobox) initialization from select has been implemented. For more information, please refer to the following post: http://www.jqwidgets.com/community/topic/change-event-does-not-fire/#post-72369.
