查询网址字符串参数用数组输出

 第一个页面：

<a href="index2.html?name=任晓强&age=29">nihao</a>

  第二个页面：

var str = location.search,
		ary = str.substring(1).split("&"),//substring str中从第二个字母开始选择，split把字符串改成数组并用&间隔两个数据
		endary = [],
		i = 0,
		len = ary.length;
 		console.log(ary,len);

		for(;i<len;i++){

				var name = decodeURIComponent(endary[0]);
				
				endary[i] = ary[i].split("=")[1];//ary[i]数组里面的数据用split转成数组并选择=后的数据

		}

		console.log(endary);

			

			test.innerHTML = "姓名："+name+"<br>年龄："+endary[1];
