JS sample code to close the web page window directly without prompting

In IE7 and IE8, the current window or tab can be closed using the close() method provided by JavaScript, but an annoying dialog box is prompted. After looking for the code, I can finally close it directly without prompting.

JavaScript code

Copy the code code as follows:

function CloseWin()

{

window.opener=null;

window.open('','_self');

window.close();

}

Example:

XML/HTML code

1.<input type=button value="Close" onclick="CloseWin()">

For the parent window, open the child window, click the child window to close, and close the parent window at the same time:

var windowParent = window.opener;

windowParent.opener = null;

windowParent.open('', '_self');

windowParent.close();
