javascript - IE has empty document.referrer after a location.replace

javascript - IE has empty document.referrer after a location.replace

I've got a site that does a complex search and has a "loading" page. On the loading page we use:

<body onload="window.location.replace('results_page.php');" >

Or:

<body onload="window.location = 'results_page.php';" >

The only difference between the two option above are that location.replace() ignores the page in the browser's history.

On the results_page I need to read the referrer for tracking purposes:

<script> alert(document.referrer); </script>

This works fine on all browsers except IE, which returns and empty value for document.referrer.

Anyone know a better way to do a javascript redirect that will give IE a value for the referrer?

p.s. This example has been made much more simple than it would be in production.

Looks like this is just the cost of doing business with IE users. Can't be fixed without a hack. Working on one now. Thanks for listening.

I used the workaround to make this function. Works like a charm.

<script type="text/javascript" >            
function redirect(url) {
    if (/MSIE (d+.d+);/.test(navigator.userAgent)){
        var referLink = document.createElement('a');
        referLink.href = url;
        document.body.appendChild(referLink);
        referLink.click();
    } else {
        location.href = url;
    }
}
</script>
