代码如下：
<!DOCTYPE>
<html lang="en">
<head>
</head>
<body>
<body>
<script>
var url = 'https://www.baidu.com/s?wd=javascript&rsv_spt=1';
window.onload = function () {
method2(url);
}; function method1(url) {
// 使用正则来 两边的参数不可能是 &=? 所以去反集[^&=?]
let regex = /([^&=?]+)=([^&=?]+)/g,
obj = {};
url.replace(regex, (...arg) => {
obj[arg[]] = arg[];
});
console.log(obj);
} function method2(url) {
let index = url.indexOf('?');
let datas = url.substring(index+, url.length).split('&');
let obj = {};
for (let item of datas) {
let data = item.split('=')
obj[data[]] = data[];
}
console.log(obj);
} </script>
