Question

I’m using Math.random to generate a random string passed in an ajax call. The problem is that the string generated contains a decimal, and the server interprets this as a file.ext (which of course doesn’t exist).

Ex from http.log:

File does not exist: /path/to/site/foo.php&arg=123&randval=0.5678719817071954, referer: http://site/bar.php?arg=123

Ajax used to generate link:

$(document).ready(function() 
{
    $(\"#placeholder\").load(\"/foo.php?arg=123\");
    var refreshId = setInterval(function() 
    {
        $(\"#placeholder\").load('/foo.php?arg=123&randval='+ Math.random());
    }, 5000);
    $.ajaxSetup({ cache: false });
});

What I’d like to end up with is:

foo.php&arg=123&randval=05678719817071954

The argument randval is not used other than to ensure I don’t wind up with a cached version of the page. It may not be needed, but this is from an example I used to set up the jquery ajax call.

Answer 1

I’d suggest, in place of Math.random(), using:

(Math.random() + '').replace('.','');
