JavaScript onClick does not work in Firefox - javascript

I have a confirmation popup that opens when a user clicks on this link:
<a onClick="openPopup('#popup1')">foo</a>
here is the relevant JavaScript:
function openPopup(id) {
$(id).show();
event.preventDefault();
$(id).addClass('is-visible');
$(id).css("z-index", "999999999999999999999999");
}
In Safari and Chrome it works fine. In Firefox, however, the trigger does not seem to work. Any ideas why?
I already tried to change the link like so:
foo
no changes though. thanks for your help!

In Firefox, however, the trigger does not seem to work. Any ideas why?
Firefox does not make the event object global. You have to pass it along to the event handler, e.g.
onClick="openPopup('#popup1', event)"
Since you are using jQuery, you should bind the handler with jQuery so that you can also use jQuery's augmented event object.

I think what you might be experiencing is a problem with the uppercase C in onClick. Try changing it to onclick (all lowercase).
See this question:
onclick or onClick?
Also you may have trouble accessing the event object:
Access global event object in Firefox
But it the case of your example I don't think you will need it.
event.preventDefault prevents the browser trying to follow a href of a link when it is clicked (you don't have an href in your example). If the link gets followed, and your browser navigates to another page you will not get a chance to see any error that may have happened and it can be very frustrating to work out what is going on, so if you do need to use event.preventDefault make sure it is on the first line of the function it is in

Shoudn't input fire 'focusout' event before the anchor fires 'click'?

I have a situation where an anchor fires the 'click' event before the input, which loses the focus and fires the 'focusout' event.
To be clear, I write something in the input and then I click the anchor. I'm expecting the 'focusout' event to be written to console first and then the 'click' event.
I'm not able to reproduce this in a dummy app like in the code below, it only reproduces in the web app I'm working on, which I can't share here.
click me
<input type="text" id="t">
<script>
document.querySelector("#a").addEventListener('click', function(e) {
console.log('click');
});
document.querySelector("#t").addEventListener('focusout', function(e) {
console.log('focusout');
});
</script>
Any idea how could it be possible for anchor to fire the 'click' event first before the input firing 'focusout' event?
I'm pretty dazzled how it's actually possible... I can't see how in the world, even if I wanted to, be able to make the 'click' fire first. I checked several times the event object in watcher in Chrome dev tools and I can't see anything peculiar
I'm using latest Chrome on Windows 10
The change event doesn't fire until the input loses focus. You can use onkeypress instead.
Ironically enough, it seems like jQuery .focusout / .click conflict has the exact opposite problem as you. From what I'm reading around the web it seems like the general concesus is that the HTML specification doesn't actually specify the order of events and it is up to the browser to implement however they see fit. However, in your case I would certainly expect focusout to happen first, tho clearly it isn't. Have you tried "onblur" instead?
I found it! This is one of those things which doesn't let you sleep well.
The issue was somewhere else, in some library, there is a mousedown handler on the anchor with a e.preventDefault():

This sucks. I don't know if I should cry or laugh.
Why would you want to do something like this?

Trying to execute a event with javascript on an <a> element

The reason i need to execute the event behind a a element is because i'm working on some kind of autologin, however one of the sites it has to work with is https://create.kahoot.it/#login?a=1&next= the problem is, their login uses an a element for the sign in button, however when i select that element and execute a .click on it it simply doesn't do the same thing as to what happens when a user clicks on it.
I hope someone could answer this question since i couldn't find anything close to this issue anywhere.
Also for the convenience of whoever helps, to select the element from the console you could use:
document.getElementById('sign-in').getElementsByTagName('a')[1];
The way to solve this issue has to be either javascript or JQuery, preferably just plain javascript.
Try this:
document.getElementsByClassName('btn register')[0].click();
This basically is selecting the anchor by its class name and fire click event manually.
UPDATE:
Alright I did some more research and it seems there is another way of triggering that click handler and it is to set href on the window:
var a = document.getElementsByClassName('btn register')[1];
window.location.href = a.href;
I've tried it and seems it is doing the job.

Selenium click event does not trigger angularjs event

I have this page where an angularjs modal-content popup, in there i fill up some fields and click save. After save is initiated, popup should dissapear an event should happen and so on.
My selenium test does all that perfectly except that when it clicks on the save button, popup dissapears but no event is triggered or saved so when i open up the window again everything is empty. I've tried stuff that i know with selenium and it still doesn't work. Can anyone help me out here?
This is the save button:
<button class="save-button" data-ng-click="onSettingsSave()" ng-hide="readOnlyMode || !canSave()">Save</button>
Stuff i've tried:
var saveButton = driver.FindElement(By.CssSelector("button.save-button"));
saveButton.Click();
var saveButton = driver.FindElement(By.XPath(saveXpath));
saveButton.SendKeys(Keys.Enter);
((IJavaScriptExecutor)driver).ExecuteScript("arguments[0].focus();",saveButton);
((IJavaScriptExecutor)driver).ExecuteScript("arguments[0].click();",saveButton );
Try force clicking the element using pure JS:
driver.execute_script("arguments[0].click();", yourElement)
You can't use $ as a shortcut for document.querySelector in a script like that.
driver.ExecuteScript("document.querySelector('#base_element_id div input').click()");
Also this probably won't trigger an onClick in react / angular
Like the OP I have tried everything I can think of to get Selenium to trigger client side javascript events. I've seen some posts across the web of people having partial success where it randomly works; in my case it never works.
Selenium does successfully trigger the browsers primary click action, be it checking a checkbox or pressing a button, but it does not trigger any attached client side javascript events.
Both the native element.Click() method in selenium, and the abstracted ExecuteScript with arguments method of clicking as suggested by #csaladenes have the same result.
The only solution I have found so far is to use pure JS through that same ExecuteScript method; basically avoid the overload with params selenium can embed.
driver.ExecuteScript("$('#base_element_id div input').click()");
In my case I am using the JQuery that is already on my page to make locating the element easier, but any form of truly pure JS should do the same thing.
EDIT:
After some additional testing, it turns out that my "fix" really did nothing. However, performing the same click more than once did cause the client side events to fire.
In my case I am checking a checkbox, so I needed to perform the click 3 times to leave it in the correct state and still have the client side events run.
This is very odd, and definitely needs some more work to figure out where the issue is at that makes this necessary.
Edit 2:
I think I have finally found a solution, and at least partial answer, that does not make me cringe.
It seems as though Selenium has an issue where sometimes it "loses" the focus of the browser. Considering how consistent and repeatable my issue is I don't think focus is the only problem in my case, however the solution works pretty well.
I was able to get the immediate parent of my checkbox, which was a div element, click that first to return focus to the page, then click the checkbox. After that sequence of events the client side events worked correctly.

can I trigger click event onload

I am having anchor tag in my page. I like to trigger click event onload . Which means I wanna open this page "http://XXXXX.com" with new tab. Because I don't wanna popup blockers. Is there anyway to do this?
anchor attrs are given bellow
id="add_redirect"
href="http://XXXXX.com"
target="_blank"
Yeah, you can use a click event called onLoad(). Just use the setTimeout() method in jquery. It will call a click function without clicking it. Here is an example:
$("document").ready(function() {
setTimeout(function() {
$("#add_redirect").trigger('click');
},10);
});
This will work for you when the page start to load and the time delay is 10ms which is negligible.
Syntax has been corrected.
Try adding the following code in the page load
document.getElementById('add_redirect').click();
Using JQuery you can do that pretty easy. The earlier posted solution also work of course.
$(document).ready(function(){
$("#add_redirect").trigger('click');
});
TRY DEMO
If your goal is to bypass pop-up blockers on page load, triggering the click event synthetically probably won't work. Browsers are smart enough to know when a click is user-generated vs. when you've called the click function on the DOM element (on those browsers were that even works). Examples: http://jsbin.com/avibi3/3, http://jsbin.com/avibi3/4
Using jQuery's trigger mechanism certainly won't do it, because it doesn't really trigger a click event at all; it just fires the handlers that jQuery hooked up (edit: and, apparently, ones defined via an onclick attribute — see Sukhi's answer — but not ones attached via addEventListener). If that's what you want to do, Sukhi's answer shows you how, although I always say: If you want code to be run from two different places, put it in a function, and call that function from two different places (rather than putting it in a click handler and then simulating a click just to run the code). There are valid use cases for trigger (mostly relating to integrating with third-party scripts), but for running your own code from two different places, it's a symptom of a design problem.

jQuery Click/Change event not working properly in IE7/8

I am binding an event to a checkbox's change or click event which works fine in Firefox but in IE I have to click anywhere else (causing the blur) event before the event is fired.
I have read and believe this is down to the way IE fires the events, but is there anyway I can get round it?
The whole point is that it is a smooth search feature which doesn't need a search button to be clicked
$('#sidebar .itemSearchModule-Form input[type=checkbox]').click(function() {
$('#sidebar .itemSearchModule-Form .saveButton').click();
});
The change event requires a blur to happen first. The Click event should not. You could always force a blur event if you wanted by $(elem).blur()
Paolo Bergantino was right so this answer credit should go to him.
It seems my code was all screwed up and another selector was getting tied up with the sample I used above.
The CLICK event does work in IE I can confirm, if you are suffering the same problem ALL I can suggest is you check your code
try giving that checkbox a class like chkbx and try:
$('.chkbx').click(function() { etc...
its just for debuggin your selector.. being sure problem is in the action. i think for IE you need to use GetElementByID.
