js关闭浏览器的tab页(兼容)

由于在脚本中使用了 window.close(), 当前非弹出窗口在最新版本的chrome和firefox里总是不能关闭，而在 IE中是可以关闭的 。

在console中弹出提示"Scripts may close only the windows that were opened by it" (脚本只能关闭它所打开的窗口),[如下图所示] , 不明白是什么原因。

经过一段时间的折腾。终于明白了问题所在。

首先，什么是非弹出窗口呢？

非弹出窗口，即是指（opener=null 及 非window.open()打开的窗口,比如URL直接输入的浏览器窗体， 或由其它程序调用产生的浏览器窗口）。

其次，window.close() 怎么理解呢？

由 https://developer.mozilla.org/en-US/docs/Web/API/window.close 可知:

Closes the current window, or the window on which it was called.
When this method is called, the referenced

window

is closed.

This method is only allowed to be called for windows that were opened by a script using the

window.open()

method. If the window was not opened by a script, the following error appears in the JavaScript Console:

Scripts may not close windows that were not opened by script.

Examples

Closing a window opened with

window.open()

This example demonstrates how to use this method to close a window opened by script calling

window.open()

.

<script type="text/javascript">
//Global var to store a reference to the opened window
var openedWindow;

function openWindow()
{
openedWindow = window.open('moreinfo.htm');
}

function closeOpenedWindow()
{
openedWindow.close();
}
</script>

Closing the current window

When you call the

window

object's

close()

method directly, rather than calling

close()

on a

window

instance, the browser will close the frontmost window, whether your script created that window or not.

<script type="text/javascript">
function closeCurrentWindow()
{
window.close();
}
</script>

在某些实际应用中，window.close() and self.close() 是不能关闭非弹出窗口（opener=null及非window.open()打开的窗口）。

方案：

1.

function closeWindows() {
var browserName = navigator.appName;
var browserVer = parseInt(navigator.appVersion);
//alert(browserName + " : "+browserVer);

//document.getElementById("flashContent").innerHTML = "<br> <font face='Arial' color='blue' size='2'><b> You have been logged out of the Game. Please Close Your Browser Window.</b></font>";

if(browserName == "Microsoft Internet Explorer"){
var ie7 = (document.all && !window.opera && window.XMLHttpRequest) ? true : false;
if (ie7)
{
//This method is required to close a window without any prompt for IE7 & greater versions.
window.open('','_parent','');
window.close();
}
else
{
//This method is required to close a window without any prompt for IE6
this.focus();
self.opener = this;
self.close();
}
}else{
//For NON-IE Browsers except Firefox which doesnt support Auto Close
try{
this.focus();
self.opener = this;
self.close();
}
catch(e){

}

try{
window.open('','_self','');
window.close();
}
catch(e){

}
}
}

2.

<script type="text/javascript">
function closeWP() {
var Browser = navigator.appName;
var indexB = Browser.indexOf('Explorer');

if (indexB > 0) {
var indexV = navigator.userAgent.indexOf('MSIE') + 5;
var Version = navigator.userAgent.substring(indexV, indexV + 1);

if (Version >= 7) {
window.open('', '_self', '');
window.close();
}
else if (Version == 6) {
window.opener = null;
window.close();
}
else {
window.opener = '';
window.close();
}

}
else {
window.close();
}
}
</script>

老式关闭当前页面js
window.opener=null;
window.open('','_self');
window.close();

但是关闭 Chrome 浏览器会有问题

Scripts may close only the windows that were opened by it.

搜了半天居然没有答案；所以我自己发上来以便别人需要

关闭当前页面js

open(location, '_self').close();

'p' is new window that i opened, i'm using jquery to test what browser you have, this is example when i open new window, populate it, call print dialog, then close it

it's not solution to original problem but just in case someone find it useful

if ( $.browser.msie ) p.location.reload(); //for IE if you want print dialog to show
p.window.print();
if ( $.browser.msie || $.browser.opera || $.browser.mozilla) p.window.close();
else p.window.self.close(); //for chrome

B:

Ordinary javascript cannot close windows willy-nilly. This is a security feature, introduced a while ago, to stop various malicious exploits and annoyances.

From the latest working spec for

window.close()

:


This means, with one small exception, javascript must not be allowed to close a window that was not opened by that same javascript.

Chrome allows that exception -- which it doesn't apply to userscripts -- however Firefox does not. The Firefox implementation flat out states:



If you try to use

window.close

from a Greasemonkey / Tampermonkey / userscript you will get:
Firefox: The error message, "

Scripts
may not close windows that were not opened by script.

"
Chrome: just silently fails.

The long-term solution:

The best way to deal with this is to make a Chrome extension and/or Firefox add-on instead. These can reliably close the current window.

However, since the security risks, posed by

window.close

, are much less for a Greasemonkey/Tampermonkey script; Greasemonkey and Tampermonkey could reasonably provide this functionality in their API (essentially packaging the extension work for you).
Consider making a feature request.

The hacky workarounds:

Chrome is currently vulnerable to the "self redirection" exploit. So code like this will currently work in Tampermonkey scripts:

open(location, '_self').close();

This is buggy behavior, IMO, and is liable to be blocked by future releases of Chrome, so use this hack with that in mind.

Firefox is secure against that exploit. So, the only javascript way is to cripple the security settings, one browser at a time.

You can open up

about:config

and set

allow_scripts_to_close_windows

to

true

.

If your script is for personal use, go ahead and do that. If you ask anyone else to turn that setting on, they would be smart, and justified, to decline with prejudice.

There currently is no equivalent setting for Chrome.

From my observation, this update fixed the issue on using

window.close()

to close the popup window. You will see this in the console when it fail, "Scripts may close only the windows that were opened by it.". That means The hacky workarounds (Brock Adams's answer) may not work in the latest release.

So, in the previous Chrome released builds, the below code block may worked but not with this update.

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

For this update, you have to update your code accordingly to close the popup window. One of the solution is to grab the popup window id and use

chrome.windows.remove(integer windowId, function callback)

method to remove it. Chrome extension windows API can be found at chrome.windows.

Actually my chrome extension MarkView was facing this issue and I had to update my code to make it work for this Chrome Update. By the way, MarkView is tool to read and write Awesome Markdown Files, it provides features including Content Outline, Sortable Tables and code block syntax highlight with line number.

I also created this post, any comments are welcome.

发现最新版本ff和chrom还是有问题，临时采用如下方式处理：

function CloseWebPage(){
if (navigator.userAgent.indexOf("MSIE") > 0) {
if (navigator.userAgent.indexOf("MSIE 6.0") > 0) {
window.opener = null;
window.close();
}else {
window.open('', '_top');
window.top.close();
}
}
else if (navigator.userAgent.indexOf("Firefox")>0 || navigator.userAgent.indexOf("Chrome")> 0) {
//window.location.href = 'about:blank ';
window.location.href="about:blank";
window.close();
}
else {
window.opener=null;
window.open('','_self');
window.close();
}
}
