js 获取Request参数

function getArgs(strParame) {
         var args = new Object();
         var query = location.search.substring(1); // Get query string
         var pairs = query.split("&"); // Break at ampersand
         for (var i = 0; i < pairs.length; i++) {
             var pos = pairs[i].indexOf('='); // Look for "name=value"
             if (pos == -1) continue; // If not found, skip
             var argname = pairs[i].substring(0, pos); // Extract the name
             var value = pairs[i].substring(pos + 1); // Extract the value
             value = decodeURIComponent(value); // Decode it, if needed
             args[argname] = value; // Store as a property
         }
         return args[strParame]; // Return the object
     }
