I want to pop up a window.alert() if the user mouses out of an area when they haven't saved changes yet (for structural reasons, there are several forms and a common problem I've seen in other apps is making changes in multiple areas, submitting one and losing the rest) and automatically close the alert when they mouse back into the area. To do that, I need the id of the window that pops up, but I'm not sure how to get it.
The window does not have an id, and you cannot close it from Javascript. It is not a part of the DOM.
You can only open an alert() box, and then wait till the user closes it. Nothing else.
No alert() please :)
Actually an alert() will block further code execution anyway so even if you COULD close it programatically it would never actually execute that dialog-closing code.
You need something you can access through the DOM (like every other response here says).
Make your Javascript track the mouse location and upon leaving the area you overlay a dark translucent background or do a modal dialog
Techniques on creating modal dialogs
I would also advise adding a pointer-events: none; and position: fixed to the underlying content to prevent further action until the user actually goes back where they should be.
If you want real specifics on how to code this let me know. I'm hoping you'll travel down the rabbit hole and discover the wonders on your own, though. Much more satisfying.

So, I've probably stumbled upon the strangest bug/feature I've ever seen. I've developed a website which helps you read foreign books. See this book (or any book on the website, it doesn't matter): https://anylang.net/en/books/de/heaven-has-no-favorites/read.
Try to quickly move your mouse hovering on words/sentences, maybe click on something etc. Everything should work pretty smooth.
On mouseover a word quickly becomes orange, on click the translation quickly appears etc.
Now click on the login button:
The first input should become focused.
Then close the modal and try the first step again. Everything becomes very laggy. The lags won't disappear no matter what you do, except:
Click on the page number:
Lags disappear. Completely.
The same result (lags) can be achieved by:
Clicking on a word inside a translation tooltip
It has a contenteditable attribute, so the behaviour is exactly the same as in the first case.
Click anywhere outside the tooltip, closing it and causing the lags.
Lags still disappear if you click on a page number (or, probably, any input[type="text"] on the page (but not in modals))
Some things to consider:
The effect doesn't disappear if you lose focuse in a modal and then close it.
The same effect can be achieved by focusing in a modal and then manually removing a modal from dom. So javascript is not the problem.
If you don't remove a modal from dom but apply "display: none" to it instead, everything is ok, no lags.
My guess is that the browser gives higher priority to elements where input[type="text"] is focused and doesn't respect it when an element with the input is removed from dom. Any other ideas? This thing really boggles my mind.
If you do a performance profile of your site while going through this process, you'll see that your memory allocation continues to climb as you interact with the page. You'll also notice that the more text you hover over the worse the lag eventually becomes.
This is indicative of a memory leak in your code - possibly caused by event listeners that aren't being cleaned up properly.
Without an in-depth review of your code it's unlikely anyone here is going to be able to pinpoint where the exact problem is, but hopefully I've pointed you in the right direction!
I have a web page that gets refreshed, when something happens on any of its children pages. When it happens, the IE pop-up appears with the following message: "To display the webpage again, the web browser needs to resend the information you've previously submitted. If you were making a purchase, you should click Cancel to avoid a duplicate transaction. Otherwise, click Retry to display". See the image attached:
I'm ok with all that, but I was wondering if there's a way to change the actual text of the message, for example, removing the last sentence. I know this pop-up can't be tampered with, but perhaps there's a way to replace it with a custom made pop-up, serving the same function, but showing a different text. I assume first I would have to suppress the original message, then call a confirm box in a beforeupdate function, where clicking OK (for example) would resend the information submitted and Cancel would let you remain on the page without refreshing it. However, my Javascript and JQuery knowledge is a bit rusty and I'm not sure how to implement it properly. Any help is appreciated.
Thank you
I am trying to make a page COMPLETELY UNCLICKABLE (both right click and left click) and to display a message when someone clicks. Since I know that this will raise lots of questions such as
"why would anyone ever want to do this...this is stupid...then nobody
can navigate the site...and it doesn't protect your content
anyway...etc"
here is the explanation of my purpose. I have a page that is at the moment only a graphic mockup of what the finished website will eventually look like. No matter how many times I explain that the mockup is ONLY AN IMAGE and not a real navigable website, they still email me to say that they cannot click on the menus and links. Since it is a single page mockup, I want to pop up an alert() message (can't use a modal because you can't click to dismiss it if clicking is disabled) to let them know that they have clicked something non-functional. I am trying to do this in as few lines of code as possible, and have the following working at the moment:
<script>
$('html').mousedown(function(event) {
event.preventDefault();//To prevent following the link
alert('Demo Graphic Only...clicking on stuff will NOT work at this point.');
});
</script>
The issue is that when using .mousedown I capture the user trying to click on the browser scroll-bar to scroll down. I was surprised by this since it is not part of the actual PAGE CONTENT but rather a part of the BROWSER...but it is catching it nonetheless. I tried using .click in place of .mousedown however only seem to catch a normal (left) click in that case... Does anyone know how to easily (minimal lines of code if possible) capture the left AND right click event, but allow user interaction with the browser scrollbar?
Try this :
$(document).click(function(event) {
event.preventDefault();//To prevent following the link
console.log('Demo Graphic Only...clicking on stuff will NOT work at this point.');
});
This Function will be called when click is made on the page , not on the Scrollbars
Try to use
event.stopPropagation();
or
event.stopImmediatePropagation()
For people who come across this question, an alternative approach, good especially if you need to prevent mousedown specifically:
Put the scrolling content in a wrapper element and prevent mousedown only on the inner element. Set the wrapper element to overflow: auto; height: 100%;
If I write:
window.onbeforeunload = function(){ return 'exit?' ;};
I get a popup to stay / leave the page.
you can create a custom pop-up in html?
the problem is this:
if I create a popup html, which is activated only when you exit from the current page, and I will see him for half a second, then change page ... how can I fix this?
I need something (like the command alert) I block the page until you press a button.
You can't do that. Which is good, because it would be really damn irritating if every website could stop me from browsing away from the page until they felt like it.
onbeforeunload is the only mechanism you've got. It ensures the browser still has enough control to let me leave if I want to, and prevents you from sticking me in an alert loop or similar.
Suppose I have a link, which would fade out the entire page when link is clicked. The reason I fade out the page is because a next page is about to load, but it is not loaded yet. I can use pointer-events: none which will disable any mouse events until the next page is loaded.
Suppose it was done with the keyboard, I could use the following to prevent double-enter, or to cleanly disable all elements within, for example tab-enter would be disabled this way as well.
parent.onkeydown = fals
parent.onkeyup = fals
parent.onkeypress = fals
function fals() {return false}
This works well for short loads, but if it takes a long time to load, the user may notice the following difficulties.
Cannot tab away from the a tag.
Cannot use several of the keyboard shortcuts which would control the browser.
Able to tab into the disabled area from the address bar.
Is there a modern and slick way to prevent these 3 problems, other than setting an onfocus=blur for all of the child elements? I do not care about IE today.
I think the commonly accepted way of dealing with things like what you're talking about is to use Modal's, which is to say when they click that link, you pop up a box that says 'Processing' or something like that, and you create a fullscreen div with a z-index above everything else so the user can't click / interact with anything else on the screen until you're done doing whatever it is you are doing.
See http://twitter.github.com/bootstrap/javascript.html#modals for an example of what i'm talking about.
