js笔试题-接收get请求参数

function getQueryString(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;}

*-----------------实现1--------------------*/function GetRequest() {var url = location.search; //获取url中"?"符后的字串var theRequest = new Object();if (url.indexOf("?") != -1) {var str = url.substr(1);strs = str.split("&");for(var i = 0; i < strs.length; i ++) {theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]);}}return theRequest;}/*--------------------实现2(返回 $_GET 对象, 仿PHP模式)----------------------*/var $_GET = (function(){var url = window.document.location.href.toString();var u = url.split("?");if(typeof(u[1]) == "string"){u = u[1].split("&");var get = {};for(var i in u){var j = u[i].split("=");get[j[0]] = j[1];}return get;} else {return {};}})();/*第2种方式, 使用时, 可以直接 $_GET['get参数'], 就直接获得GET参数的值*/
