How can I trigger a JavaScript event click

Question

I have a hyperlink in my page. I am trying to automate a number of clicks on the hyperlink for testing purposes. Is there any way you can simulate 50 clicks on the hyperlink

Answer 1

IE9+

function triggerEvent(el, type){
    var e = document.createEvent('HTMLEvents');
    e.initEvent(type, false, true);
    el.dispatchEvent(e);
}

Usage example:

var el = document.querySelector('input[type="text"]');
triggerEvent(el, 'mousedown');
