没有确认对话框如何关闭窗口？

Question

window.close();

以上将每次弹出一个确认对话框，而在Firefox中根本不工作。

Answer 1

Use this way

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

Answer 2

I think that's not without a reason. People don't like windows being closed without notice.

Answer 3

Closing a browser window is not as straight-forward as it used to be years ago.

Typically, a newly opened window can be closed if:
1. the 'close' is called within the DOM of the window itself
2. the closer is the opener

However, with almost all browsers having tabs, if the opened window is the only remaining tab in the main window, it might not close without prompt for above case 1. Even if it closes, it might just close the tab and leave the main window opened.

Answer 4

You can't - it's a security feature. You'll need to look into showing some form of modal dialog if you wish to be able to close it. Have a look at something like This JQuery Example which features auto-close

Answer 5

it works in chrome,firefox need to turn the "allowjavascriptclosewindow" option on. ie need alter your code as: window.open("","_self"); window.close();

Answer 6

未通过JavaScript打开的Windows无法使用JavaScript自动关闭（我无法想到网站关闭访问者到达网站的窗口的任何充分理由，在此过程中丢弃其返回历史记录）

Answer 7

The below javascript works fine to close the tab with user confirmation.

<script>
function closeWindow()
  {
if (confirm('Are you sure you want to close the Window? All the unsaved data will be lost')) {
top.window.open('','_self','');
top.window.close();       
} 
}
</script>
