Assign a value to JS based on the property name of the URL

1. Method One: JS Regular expression: request path: http://127.0.0.1/pec/jsp/member/refundOrder.jsp?status=4

<script>
    var status= getUrlAttribute(‘status‘);
    if(null!=status)
    {
        alert(status);
    }
    function getUrlParam(name) {
        var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)");
        var r = window.location.search.substr(1).match(reg);
        if(r != null) {
            return unescape(r[2]);
        }
        return null;
    }
</script>

2. Square Two:

Function getUrlParam(parameName){
     //location.search is a string starting from the ? of the current URL, ie the query string
     Var query = (location.search.length > 0 ? location.search.substring(1) : null);
     If(null!=query)
     {
         Var args = new Object( );
         Var pairs = query.split("&");
         For(var i = 0; i < pairs.length; i++)
         {
             Var pos = pairs[i].indexOf("=");
             If (pos == -1)
                 Continue;
             Var argname = pairs[i].substring(0,pos);
             Var value = pairs[i].substring(pos+1);
             Value = decodeURIComponent(value);
             Args[argname] = value;
         }
         / / Get the value according to the key name
         Return args[parameName];
     }
     Return null;
}
