使用javascript禁用IE中的关闭按钮

Question

Can I disable close button in IE using javascript? maybe like "Resizeable =no ". But i dont want to use "fullscreen = yes". How ?

Answer 1

This is impossible in modern browsers. Browser makers want to provide a user-friendly and relatively predictable experience, which includes not making features that would be useful primarily to makers of spyware or heavily obnoxious, impossible-to-close-without-clicking ads.

The best you can do is to capture the user leaving the page and popup a dialog asking them if they're sure they want to. You cannot cancel the event.

Example (works in IE):

window.onbeforeunload = function(evt)
        {
            if (unsavedData)
            {
                var message = 'Leaving the page will result in the loss of unsaved data.';
                if (typeof evt == 'undefined')
                {
                    evt = window.event;
                }
                if (evt)
                {
                    evt.returnValue = message;
                }
                return message;
            }

        }

出于安全原因，您不能仅使用javascript来做到这一点。

If this is for an intranet site or a kiosk, you can use HTML Applications. HTML Applications are just HTML files that can be made to look and feel like regular Windows applications.

If, for example, you want a full screen Kiosk application just install a proper HTA file on the computer at runs on start up with the following configuration in the head section:

<HTA:APPLICATION ID="MyApp" 
    APPLICATIONNAME="Kiosk" 
    BORDER="none"
    CAPTION="no"
    ICON="/graphics/creature.ico"
    SHOWINTASKBAR="no"
    SINGLEINSTANCE="yes"
    SYSMENU="no"
    WINDOWSTATE="maximize">

The Border="none" part makes a window that doesn't have a close button.

Remember though, this wont work on a regular web page because disabling the close button is a dangerous thing for an untrusted web page to do. By using an HTA you tell Windows that you can trust this page.
