通过javascript获取get请求的参数
整个类的代码如下：/** * 获取get请求中的参数 ** @author MaLong * @param loc * （可选String or Object） String 类型须为URL， Object则为Location的对象 * 默认为window.location */var Request = function(loc) {var paramsStr;var hashSearchString;if (!loc || typeof loc == "object") {loc = loc || window.location;if (/#.+\?/.test(paramsStr)) {paramsStr = loc.hash;} elseparamsStr = loc.search;} else if (typeof loc == "string") {if (/.*\?.+[#.+]?/.test(loc))paramsStr = loc.replace(/.*\?/, "");elseparamsStr = loc.replace(/.*#/, "#");}if (!/#.+\?/.test(paramsStr)) {this.pageSelector = paramsStr.replace(/^\?.*#$/, "#");hashSearchString = paramsStr.replace(/\?|(#.+)/, "");} else {this.pageSelector = paramsStr.replace(/\?.*$/, "");hashSearchString = paramsStr.replace(/#.+\?/, "");}var params = hashSearchString.split("&");var reg = /^(\w+)=(.*)$/;this.paramsMap = {};for ( var i = 0, length = params.length; i < length; i++) {var _p = reg.exec(params);if (_p)this.paramsMap] = _p;}}Request.prototype = {/** * 根据参数名获取参数值 ** @param name * @return 参数值 */getParam : function(name) {return this.paramsMap;},/** * 设置参数名和参数值 ** @param name * 参数名 * @param value * 参数值 */setParam : function(name, value) {this.paramsMap = value;},/** * 获取所有参数 ** @returns 封装所有参数名和参数值的json */getParams : function() {return this.paramsMap;},/** **/paramSize : function() {},/** **/getHashParam : function() {},/** * pageSelector 为通过hash值改变页面而预留，例：xxx.com#pageSelector */getPageSelector : function() {return this.pageSelector;}}
调用：
if(!/.*\?.+/.test(dataUrl)) dataUrl=window.location; //dataUrl 可选 var request = new Request(dataUrl); var userName=request.getParam("userName");
