JS example code that does not prompt to close the page window directly _javascript tips

In IE7, IE8, the Close () method provided with JavaScript closes the current window or tag, but prompts the annoying dialog box to find the code and can finally be closed without prompting.

JavaScript code

Copy Code code as follows:

function Closewin ()
{
Window.opener=null;
window.open (', ' _self ');
Window.close ();
}

Instance:

xml/html Code
1.<input Type=button value= "Close" onclick= "Closewin ()" >

To open the child window for the parent window, click the child window to close and close the parent window:
var windowparent = Window.opener;
Windowparent.opener = null;
Windowparent.open (', ' _self ');
Windowparent.close ();
