js获取url参数

 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=10
25     var args = getQueryStringArgs();
26     alert(args["q"]); //"javascript"
27     alert(args["num"]);//"10"
