Q1230 How can I capture the window close event when the user clicks the window close icon?
irt.org | Knowledge Base | JavaScript | Window | Q1230 [ previous next ] Q1230 How can I capture the window close event when the user clicks the window close icon?The onUnload event is the one to use. To capture the close you need to set a flag on all links telling the browser that you are just leaving the page, not closing:
Leave out the onClick on external links if you want to treat leaving your site as a close. Note! Do not expect the page to be available to a function in the onUnload! So if you try to read the contents of a form on the page in the browser that is closing, you might get JavaScript errors. In Microsoft Internet Explorer 4+ (but not Netscape Navigator) you can use the onBeforeUnload event to do whatever you want. Setting the event return value to any non-blank value in the onBeforeUnload will trigger a 'Are you sure your want to leave?' dialogue. In Netscape Navigator the onLoad event is notoriously unreliable. Feedback on 'Q1230 How can I capture the window close event when the user clicks the window close icon?' |
