js 获取URL中参数

function getQueryString() {
var result = location.search.match(new RegExp("[\?\&][^\?\&]+=[^\?\&]+", "g"));
if (result == null) {
return "";
} for (var i = 0; i < result.length; i++) {
result[i] = result[i].substring(1);
} return result;
} //根据QueryString参数名称获取值
function getQueryStringByName(name) {
var result = location.search.match(new RegExp("[\?\&]" + name + "=([^\&]+)", "i"));
if (result == null || result.length < 1) {
return "";
} return result[1];
