使用JavaScript获取URL中的参数(两种方法)

//取url参数 var type = request("type")function request() {var query = location.search;var paras = arguments[0];if (arguments.length == 2) {query = arguments[1];}if (query != "") {if (query.indexOf("?") != -1) {query = query.split("?")[1];}query = query.split("&");for (var i = 0; i < query.length; i++) {var querycoll = query[i].split("=");if (querycoll.length == 2) {if (querycoll[0].toUpperCase() == paras.toUpperCase()) {return querycoll[1];break;}}}}return "";}//调用方法var mid=request("mid");

unction request(name) {var reg = new RegExp('(^|&)' + name + '=([^&]*)(&|$)', 'i');var r = window.location.search.substr(1).match(reg);if (r != null) {return unescape(r[2]);}return null;}// 这样调用：alert(request("mid"));
