Javascript – detecting browser back button in javascript/jquery without using any external plugins

back-buttonhtmlinternet explorerjavascriptjquery

I want to detect browser back button in java-script/jquery without using any external plugins.

I am going to support following browsers

IE8,IE9,FireFox,Chrome

I googled so many links and found below part of code from code project

<body onbeforeunload=”HandleBackFunctionality()”>

function HandleBackFunctionality()
{
    if(window.event)
   {
        if(window.event.clientX < 40 && window.event.clientY < 0)
        {
            alert("Browser back button is clicked...");
        }
        else
        {
            alert("Browser refresh button is clicked...");
        }
    }
    else
    {
        if(event.currentTarget.performance.navigation.type == 1)
        {
             alert("Browser refresh button is clicked...");
        }
        if(event.currentTarget.performance.navigation.type == 2)
        {
             alert("Browser back button is clicked...");
        }
    }
}

The above code working fine IE browser. that means i can able to get the window.event.clientX and clientY values in IE browser. but in chrome/firefox not working.

When browser back button is clicked, i need to refresh the page.

how can i detect browser back button click event in all browsers (IE,firefox,chrome)

any help would be appreciated.

That can be simply dropped into your web page, and when the user clicks back, it will call a function. The default function on this call is a javascript alert “Back Button Clicked”.

To replace this functionality, you simply need to override the OnBack function. This can be done by using the code below.

<script type="text/javascript">
bajb_backdetect.OnBack = function()
{
   alert('You clicked it!');
}
</script>

This will now replace the “Back Button Clicked” alert with a “You clicked it!’” alert.
