HTMLElement.click() would not fire an expected event

Question

I try to use some simple native javascript code, in order to simulate a user click on a button at script.google.com:

document.querySelector("#runButton").click();

When I do it, nothing really happens, but when I really click on this element (#runButton), I can see a popup shows up.

It might have something to do with the fact that #runButton is a div, cause when I do the same with anchor() elements, it works.

Any ideas what I can do to better simulate this click? Something specific about google apps script editor that prevents me from doing it?

Looks like Google Apps Script editor supresses programmatic click events on interface buttons, here is solution to emulate "click" on those buttons:

function doClick(n)
{
    e = document.createEvent("MouseEvents");  
    e.initEvent("mousedown", true, false);  
    n.dispatchEvent(e,true); 
    e = document.createEvent("MouseEvents");  
    e.initEvent("mouseup", true, false);  
    n.dispatchEvent(e,true);
}

// do the click
doClick(document.getElementById("runButton"));
