获取href所带参数

function getQueryStringArgs() {
				var qs = (location.search.length > 0 ? location.search.substring(1) : ""),
					args = {},
					items = qs.length ? qs.split("&") : [],
				    item = null,
					name = null,
					value = null,
					i = 0,
					len = items.length;
				for(i = 0; i < len; i++) {
					item = items[i].split("=");
					name = decodeURIComponent(item[0]);
					value = decodeURIComponent(item[1]);
					if(name.length) {
						args[name] = value;
					}
				}
				return args;
			} 

用法： 

getQueryStringArgs（).name
