In Chrome browsing, closing the window JS is invalid. (window. Close ())

In Chrome, window. Close () is invalid. Window. Open ('', '_ Self ','');

<SCRIPT> function closechrome () {var browsername = navigator. appname; alert (browsername); If (browsername = "Netscape") {window. open ('', '_ Self',''); window. close ();} else {window. close () ;}</SCRIPT>

If the browser name is Netscape, it indicates chrome or Google.

Postscript:

Window. Close (); whether written in JS functions or written directly in onlick = "window. Close ();'

When the window is closed in IE, a prompt is displayed.

Previously, when comparing browser. appname, there was less than one equal sign.

It is equivalent to the value assignment operation. Therefore, it is considered that there is no prompt when IE is disabled in Js.

Note:

After that, you must pay attention to the Javascript equivalent judgment.
