禁用退格按钮并在mozilla firefox中刷新. [英] Disabling backspace button and refresh in mozilla firefox.

问题描述

HI，

我想禁用退格按钮.我使用了以下代码.在IE中，它可以工作，但在Firefox中.

代码段:

I want to disable the backspace button. I used the following code. In IE it is working,but in Firefox.

Code Snippet:

if(event.keyCode == 8)
                    {
                      return false;
                    }

然后，我使用了以下代码，它可以工作，但是页面令人耳目一新.我还需要禁用刷新.

Then I used the following code, it is working but the page s refreshing. I also need to disable the refresh.

function noBack()
            {
             window.history.forward()
            }
            noBack();
            window.onload = noBack;
            window.onpageshow = function(evt)
            {
            if (evt.persisted)
             noBack()
            }
            window.onunload = function()
            {
            void (0)
            }

请帮我解决这个问题.

Pls help me to overcome this issue.

I replied to a similar question yesterday: prevent browser backbutton[^]

You cannot handle browsers back button or refresh button 100%. There are multiple ways and scenario that can trigger either of them.

Instead, your design/implementation should be such that it is not affected by such interferences.

Here, in case of timer, refresh would reset it if the timer is on client side. You need to put some logic to track time on server side and validate it. Handle refresh occurance if it happens. Further, put a red message and display it to user that ''DO NOT REFRESH'' or you will loose something ;)

Just for validation purpose:
