Program
| The code is as follows |
Copy Code |
| Window.onunload = function () {
var a_n = window.event.screenx-window.screenleft;
var a_b = a_n > document.documentelement.scrollwidth-20;
if (a_b && window.event.clienty< 0 | | Window.event.altKey) {
alert (' close page behavior ');
}else{
alert (' Jump or Refresh page behavior ');
}
} |
It works with the Close button in the upper-right corner of the browser, but it doesn't work when you close the tab and close it on the taskbar.
JS tags only onloadonunloadonbeforeunload events, and no onclose events.
The OnUnload event is performed regardless of whether the page is closed or refreshed.
How do I capture a page close?
The onload is only executed when the page loads
Only perform onunload when page closes
When the page is refreshed, execute onbeforeunload First, then onunload, and finally onload.
So we can add a tag in the onbeforeunload and judge the tag in the onunload to see if the page really shuts down.

The above method has no way to judge the browser of multiple tabs, such as 360,IE8, see below

function Closeopen (event) {

The above only can not be used in the taskbar closed, basic to meet our requirements.
