How do I programmatically click on an element in firefox?

By : Bruce

In IE, I can just call from JavaScript - how do I accomplish the same task in Firefox? Ideally I'd like to have some JavaScript that would work equally well cross-browser, but if necessary I'll have different per-browser JavaScript for this.

For firefox links appear to be "special". The only way I was able to get this working was to use the createEvent described here on MDN and call the initMouseEvent function. Even that didn't work completely, I had to manually tell the browser to open a link...

var theEvent = document.createEvent("MouseEvent");
theEvent.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);
var element = document.getElementById('link');

while (element)
    if (element.tagName == "A" && element.href != "")
        if ( == "_blank") {,; }
        else { document.location = element.href; }
        element = null;
        element = element.parentElement;

The document.createEvent documentation says that "The createEvent method is deprecated. Use event constructors instead."

So you should use this method instead:

var clickEvent = new MouseEvent("click", {
    "view": window,
    "bubbles": true,
    "cancelable": false

and fire it on an element like this:


as shown here.

I used KooiInc's function listed above but I had to use two different input types one 'button' for IE and one 'submit' for FireFox. I am not exactly sure why but it works.


<input type="button" id="btnEmailHidden" style="display:none" />
<input type="submit" id="btnEmailHidden2" style="display:none" />

// in JavaScript

var hiddenBtn = document.getElementById("btnEmailHidden");

if (hiddenBtn.fireEvent) {
else {
    // dispatch for firefox + others
    var evObj = document.createEvent('MouseEvent');
    evObj.initEvent(eType, true, true);
    var hiddenBtn2 = document.getElementById("btnEmailHidden2");

I have search and tried many suggestions but this is what ended up working. If I had some more time I would have liked to investigate why submit works with FF and button with IE but that would be a luxury right now so on to the next problem.
