I have a piece of JavaScript that dynamically creates an A tag inside of an existing div and then calls the jQuery function \"click\" on it. This works as inten
Trevor Dixon's answer does fix Safari, but breaks in even the latest Firefox:
TypeError: Not enough arguments to MouseEvent.initMouseEvent
The best way to support Safari—without breaking Firefox—would be using initEvent instead of initMouseEvent like so:
var element = document.getElementById('your_id_here');
if(element.click)
element.click();
else if(document.createEvent)
{
var eventObj = document.createEvent('MouseEvents');
eventObj.initEvent('click',true,true);
element.dispatchEvent(eventObj);
}
To update for 2016, MouseEvent should be used instead of initMouseEvent which is deprecated:
var eventObj = new MouseEvent("click", {
bubbles: true,
cancelable: true
});
element.dispatchEvent(eventObj);
$('.shell a')[0] gets a DOM object out of the jQuery object. That DOM object only has DOM methods (not jQuery methods) and there is no industry standard .click() method on an <a> element until HTML5 and it is not yet implemented in every browser - thus you will see incomplete implementation across difference browsers.
You have a couple choices. The first option gets a jQuery object and uses the .click() method on the jQuery object. This will only work reliably if you are triggering jQuery click handlers, not if you just want the default click for the <a> tag.
function writeAndClickLink(url) {
$('.shell').html('<a href="' + url + '"></a>');
$('.shell a').eq(0).click();
}
Or, if clicking the URL is just going to go to a new web page, don't even bother modifying the DOM and just set window.location as there is no point in modifying the DOM at all if you're just going to a new web page:
function writeAndClickLink(url) {
window.location = url;
}
var a = $('.shell a')[0];
var evObj = document.createEvent('MouseEvents');
evObj.initMouseEvent('click', true, true, window);
a.dispatchEvent(evObj);

$('.shell a')[0] returns the native DOM element which dosn't have jQuery methods bound to it
Remove the "[0]" to keep the jQuery object in order to use jQuery methods
$('.shell a').click()
