How to set a JavaScript breakpoint from code in Chrome?
(12 answers)
Closed 8 years ago.
How do I force a breakpoint in JavaScript code on event (i.e. on button click) ?
I am using Google Chrome.
Are there any browser compatibility issues that might come with it?
Set up a button click listener and call the debugger;
Example
$("#myBtn").click(function() {
debugger;
});

How can I detect a user about the exit the page? [closed]

Does anyone know if it's possible to show a popup model on page exit(close tab/refresh/go back) with images and text using Javascript/jQuery?
The closest thing I found was beforeunload but it seems to only show an alert prompt with a predefined message.
I don't think modern browsers support a custom message in the beforeunload modal popup. Check this post for a discussion on browser compatibility

I am trying to call window.resizeTo but it is not working. I read somewhere that window.resizeTo will not work until window.open is called. Can I resize the window without calling window.open using jQuery?
As you say, you cannot resize windows which you didn't create using window.open. It is not possible in modern browsers, whether you use jQuery or not.

No, there's no cross-browser way to do this. (I don't even know of one browser that exposes that functionality.)

How can you programmatically tell an HTML SELECT to drop down (for example, due to mouseover)?

I would like to know if there is an event in Firefox that opens an html select.
In Chrome 'mousedown' works, but in Firefox it doesn't.
My code is something like
event = new MouseEvent('mousedown',{
'view': window
});
$(selector).dispatchEvent(event);
There are many similar questions but I wasn't able to come up with a definitive answer...
