programmatically open select drop down
I have created a Effective date drop down in my application using <select> and i want to open the drop down when a user presses enter key, which does not happen in firefox. I checked multiple forums but could not find a solution to do it. Can you please help? I tried doing this:
$(document).keyup(function(e) {
if (e.keyCode == 13){
if($("#effDateStartMonth").is(":focus")){
e.preventDefault();
// Option 1 angular.element("#effDateStartMonth").triggerHandler('mousedown');
// Option 2 angular.element("#effDateStartMonth").mousedown();
/* Option 3 var event;
event = document.createEvent('MouseEvents');
event.initMouseEvent('mousedown',true,true,window);
this.dispatchEvent(event); */
}
}

This forum has mixed results when you paste HTML. A leading space triggers a <pre> block. Omitting the comment block:

Are your libraries up-to-date? I have never used AngularJS, so it's a black box to me.
Firefox has various security rules about when keyboard and mouse actions can be generated by a script, or should I say, when they will be discarded as untrusted.
Do you see any messages in either of Firefox's consoles along those lines when your keyboard handler runs?

Do you know how to do it using jquery? I will make it work for angularjs. Also, I am not getting any error in consoles, it just does not open drop down on key press.
I don't know jQuery well enough, either.
From what I see in search results, mousedown is a dead end. Lots of other ideas out there. For example:
