JavaScript shuts down IE6, IE7

When you close the browser through JavaScript, "General" will pop up the system's default prompt box, prompts the user whether to close the browser, this can be solved by JavaScript, but IE6,IE7 solution is different, please see the following code.

if (ieversion = = "6.0") {Window.opener=null; Window.close ();} else if (ieversion = "7.0") {window.open (', ' _parent ', '); Window.close (); }

The note here is that if you want to close the entire browser under IE7, window.open (', ' _parent ', '); The 2nd parameter in should be modified to ' _self ', and ' _parent ' Closes the individual tab page.
