问题 I'm using javascript window.onbeforeunload function to show an alert to user whenever user tries to leave the page without submitting the data. This functinality is working fine.

问题 I have an issue with a task management application where occasionally users close their browsers/tabs and the information which they type goes away because they accidentally close a browser/tab, resulting in the loss of the text which they've entered ( and some can spend half an hour entering in text ). So I have to provide a solution, I have a couple ideas but wanted input on the best to go with, or if you have a better solution let me hear ya. Option 1: On the window.onunload or possibly

Detecting page unload in angularjs

问题 I have a javascript object which I need global to my angularjs application. When the application is about to be unloaded (due to a page refresh or some other scenario), I would like to persist the object to browser storage. I believe adding the object to $rootScope would fulfill the first requirement of making the object global, but writing the object to storage during the onbeforeunload event, would require access to the $rootScope variable. Is it possible to detect a page unload event in

问题 I'm using JQuery to capture the unload event when a user navigates away from a page. This works just fine, but I have data that needs to be saved only in the event that the user really wants to leave. Here's my catch-22. If I save the code too early and the user doesn't want to leave, I've spoiled the state of the web service backing the code. Therefore I need to accomplish the near insurmountable task of executing code only if the 'beforeunload' dialog returns true. $(window).on(

I'm building a site using the JFileUpload applet and want to handle the closing of a page in a certain way. JSTransferCancelled is called when the applet is cancelled.

问题 I want to notify the server on user closes browser window.

问题 I just want to show a message before leaving the page, but my code doesn't works: window.onload=function(){ alert("Page with a digital clock"); setInterval(clock,1000); } window.onbeforeunload=function(){ alert("Are you sure to leave this page?"); } The "onload alert" works fine, but the second is not working.. 回答1: You can't put an alert inside onbeforeunload.
