1 function request(paras) { 2         var url = location.href; 3         var paraString = url.substring(url.indexOf("?") + 1, url.length).split("&"); 4         var paraObj = {} 5         for (i = 0; j = paraString[i]; i++) { 6             paraObj[j.substring(0, j.indexOf("=")).toLowerCase()] = j.substring(j.indexOf("=") + 1, j.length); 7         } 8         var returnValue = paraObj[paras.toLowerCase()]; 9         if (typeof (returnValue) == "undefined") {10             return "";11         } else {12             return returnValue;13         }14     }15 16  17 18 var facadeInteriorResourceInfoID = request("facadeInteriorResourceInfoID");19 20 var facadeInteriorImageID = request("facadeInteriorImageID");

 另外一种方式，效率更高些，且更完善（来自JavaScript高级编程）：

1  function getQueryStringArgs() { 2         var qs = (location.search.length > 0 ? location.search.substring(1) : ""), 3         args = {}, 4         items = qs.length ? qs.split("&") : [], 5         item = null, 6         name = null, 7         value = null, 8         i = 0, 9         len = items.length;10 11         for (i = 0; i < len; i++) {12             item = items[i].split("=");13             name = decodeURIComponent(item[0]);14             value = decodeURIComponent(item[1]);15 16             if (name.length) {17                 args[name] = value;18             }19         }20 21         return args;22     }23 24     //查询字符串为?q=javascript&num=1025     var args = getQueryStringArgs();26     alert(args["q"]); //"javascript"27     alert(args["num"]);//"10"
