问题 According to the documentation (I'm only using Firefox ) : https://developer.mozilla.org/en/DOM/window.onunload The unload event is raised when the document is unloaded. But my code below would trigger the alert even though the child window (i.e. variable name "win") has just been opened , not closed. alert("failed but still reload:" + win.isSuccess); "failed but still reload: undefined" My attention is to invoke that onunload when the child window is closed. What am I doing wrong here?? Code

user-unfriendly onbeforeunload / onunload

问题 I'm struggling with onbeforeunload, onunload and generating the right messages at the right time. Any idea welcome. This is the situation: when I use onbeforeunload, the user gets a message to choose whether to navigate away, but I can't turn it off - the message is standard and appears regardless what's in the event handler. when I use onunload, I can control the "bye" messages that occur, but I cant offer the user the opportunity to change their mind. So for example, if there is data to

问题 I want to count how much time visitors spend on a certain page and store it in my MySQL DB. I thought of just starting a timer on window.onload like this: window.onload= startCount; window.onunload= sendCount; var b=0; var y; function startCount() { document.getElementById('livecount').innerHTML=b; b=b+1; y=setTimeout("startCount()",1000); } and after the visitor leaves the page (window.onunload), I'm sending the time through an XMLHttpRequest to a PHP file, which will store it in my DB:

Perform an asynchronous service get when closing browser window / tab with Angular

问题 I'm currently trying to make an Angular app make an API service call when the user tries to navigate away from my page. Either by closing the tab / window, or typing in an external URL. I've tried to implement several different ways I've seen described here on stackoverflow questions, but none seem to have the desired effect. Some mention sync ajax requests which have been, or are in the process of being deprecated in onbeforeunload on Chrome. Others advise the use of XMLHttpRequests, which

Get url for the page being opened next in window.onunload event

问题 Is there a way get the location for page being opened next in the window.onunload event. Best Regards, Keshav 回答1: No! That would be a security problem. Imagine someone navigating from a porn site to a banking site. The other way round (with the HTTP Referrer header) is already somewhat a headache. Firefox allows to suppress the referrer: Enter about:config in the address bar Search for referer (sic) Set network.http.sendRefererHeader to 0 (Courtesy to http://cafe.elharo.com/privacy/privacy

问题 <html> <body> <button type="button" onclick="clickme()">Click Me</button> <script> var test = 0; function clickme() { test = 1; console.log(test); } window.onunload = function() { alert("test"); } </script> </body> </html> I'm using this simple code to test some things with onunload and onbeforeunload. For some reason whenever I refresh/leave the page and cause the onunload event I get no alert and an error in the Firebug console. If I use onbeforeunload this works and I get no error, but I

DOM Window unload event, is it reliable?

问题 Can I rely on the window unload event to be triggered when a user closes a tab/window/browser? Edit: Found a list of what triggers the unload event in IE. http://msdn.microsoft.com/en-us/library/ms536973%28VS.85%29.aspx I would like to know in which edge cases the unload event won't be triggered. 回答1: You will likely want to use the "onbeforeunload" event too, it provides more control than the "onunload" event. That said, be aware that: Opera doesn’t fire the unload event when the browser

How can I get the destination URL for the onbeforeunload event?

问题 I've searched for hours, but I couldn't find a solution for this. window.onbeforeunload = warn; This doesn't work: function warn (e) { var destination = e.href; alert(destination ); } Okay, so to clear the things. If the user clicks on a link on the page itself, it is easy, because you can add an eventhandler to all of the links onclick event, but. I want to catch the address, what the user types into the url box of the browser. 回答1: Because it can't be done. The new location is private

问题 I am working on a Web Hosting panel which has a DNS records manager. I have to use a lot of JavaScript to make it perform almost like a desktop application. I really wanted to show a Custom Dialog window when a a browser runs beforeunload however after some research I have discovered I am stuck using the browsers default Dialog window. So this JavaScript code below does just that, my problem is I need to make sure it does NOT get fired off on certain link clicks. I am hoping to be able to

问题 Recently I updated my Google Chrome browser to Version '54.0.2840.71 m' and suddenly javascript 'onUnload' event has stopped working. I am sure, it was working fine before the upgrade. In my code (mentioned below), I am trying to open a 'Child' window from a 'Parent' window and when the child window is closed/refreshed (i.e. when its unload event is triggered), it should also reload or refresh the parent window.
