实现url参数读取的两种办法

法一：需要引入jQuery

(function ($) {

$.request = (function () {

var apiMap = {};

function request(queryStr) {

var api = {};

if (apiMap[queryStr]) { return apiMap[queryStr]; }

api.queryString = (function () {

var urlParams = {};

var e,

d = function (s) { return decodeURIComponent(s.replace(/\+/g, " ")); },

q = queryStr.substring(queryStr.indexOf('?') + 1),

r = /([^&=]+)=?([^&]*)/g;

while (e = r.exec(q)) urlParams[d(e[1])] = d(e[2]);

return urlParams;

})();

api.getUrl = function () {

var url = queryStr.substring(0, queryStr.indexOf('?') + 1);

for (var p in api.queryString) { url += p + '=' + api.queryString[p] + "&"; }

if (url.lastIndexOf('&') == url.length - 1) { return url.substring(0, url.lastIndexOf('&')); }

return url;

}

apiMap[queryStr] = api;

return api;

}

$.extend(request, request(window.location.href));

return request;

})();

}(jQuery));

用例：

var queryString = $.request(location.href).queryString;

var status=queryString.editStatus;

法二：原生js

function GetQueryString(name) {

var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)");

var r = window.location.search.substr(1).match(reg);

if (r != null) return unescape(r[2]); return null;

}

用例：

var openId = GetQueryString("openId");

法三：这个考虑的比较简单的url字符串的情况，建议用以上两种写法

function GetQueryString(str){ 

var arr=window.location.search.substr(1).split("&");

var result="";

for(value in arr){

var temp=arr[value].split("=");

if(temp[0]==str){

result=temp[1];

return result;

}

}

}
