I am working with an existing web app, in the app there are a variety of submit buttons on different forms, some using regular http post, some defining an onClick function, and some binding a js event handler to the button using a class on the element.
What I want to do, is bind another event handler to these buttons by just adding a class to the buttons, but what I want to determine is will the new event handler be guaranteed to be executed, or could one of the form submit actions happen before it does meaning my new function isn't hit.
The example scenario is I want to add a class to these buttons that bimds them all to a common js function that simply logs usage to some api. Is there a risk that the logging function isn't called because the form submit has navigated away from the page?
I've not done loads of js development, and I could test this 100 times over and just get lucky with it firing.
Below is some code I have tested with for one of the examples - again, I'm not asking how to bind multiple events, the question is to about my understanding of the spec and whether execution of all handlers is guaranteed.
$(document).ready(function(){
$('.testingBtn').click(function() {
window.location.replace(http://stackoverflow.com);
});
$( .testingBtn ).click(function(){
alert('submitting!');
});
});
<input class=testingBtn type=submit id=submitform value=Complete Signup />
As seen above, I can bind the multiple events, and in this example, just directed to another url, but this could be a form.submit()
etc. In my testing the alert has always fired first, but am I just getting lucky with the race conditions?
