截取地址栏URL参数

UrlParm = function() { // url参数var data, index;(function init() {data = [];index = {};var u = window.location.search.substr(1);if(u != '') {var parms = decodeURIComponent(u).replace(/&amp;/g,"&").split('&');for(var i = 0, len = parms.length; i < len; i++) {if(parms[i] != '') {var p = parms[i].split("=");if(p.length == 1 || (p.length == 2 && p[1] == '')) { // p | p=data.push(['']);index[p[0]] = data.length - 1;} else if(typeof(p[0]) == 'undefined' || p[0] == '') { // =c | =data[0] = [p[1]];} else if(typeof(index[p[0]]) == 'undefined') { // c=aaadata.push([p[1]]);index[p[0]] = data.length - 1;} else { // c=aaadata[index[p[0]]].push(p[1]);}}}}})();return {// 获得参数,类似request.getParameter()parm: function(o) { // o: 参数名或者参数次序try {return(typeof(o) == 'number' ? data[o][0] : data[index[o]][0]);} catch(e) {}},//获得参数组, 类似request.getParameterValues()parmValues: function(o) { // o: 参数名或者参数次序try {return(typeof(o) == 'number' ? data[o] : data[index[o]]);} catch(e) {}},//是否含有parmName参数hasParm: function(parmName) {return typeof(parmName) == 'string' ? typeof(index[parmName]) != 'undefined' : false;},// 获得参数Map ,类似request.getParameterMap()parmMap: function() {var map = {};try {for(var p in index) {map[p] = data[index[p]];}} catch(e) {}return map;}}
}();
