Add URL parameter value to input box

I have jQuery script that takes a URL parameter and adds the value to an input box.

When the URL is the form of www.mysite.com/page/?number=10 everything works fine. When the url includes .php at the end of the page than the script doesn't work, e.g. www.mysite.com/page.php?number=10.

I need for the script to work with .php is used.

Here is the script:

  jQuery(document).ready(function() {
    (function($) {
        jQuery.QueryString = (function(a) {
            if (a == "") return {};
            var b = {};
            for (var i = 0; i < a.length; ++i)
            {
                var p=a[i].split('=');
                if (p.length != 2) continue;
                b[p[0]] = decodeURIComponent(p[1].replace(/+/g, " "));
            }
            return b;
        })(window.location.search.substr(1).split('&'))
    })(jQuery);

    jQuery.QueryString["number"];

    jQuery("#entry_2081224724").val(jQuery.QueryString["number"]);

  });

Read this:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions

Your issue is, the regular expression character + gives an instruction to repeat the character that precedes it one or more times. The syntax error your getting is telling you that you haven't given it a character to repeat.

Are you trying to replace all + characters? If so, you're going to need to escape it with \.

Are you trying to say "one or more / characters"? Again, you'll need to escape that too, because / denotes the beginning of a regular expression.
