JavaScript：URLSearchParams 解析地址栏参数

[smileyby]

let query = window.location.search.slice(1);
let query = 'ie=utf-8&f=8&rsv_bp=1&tn=baidu&ie=wtf';

需要注意 query 是地址中 ? 之后的部分 window.location.search.slice(1)
let searchParams = new URLSearchParams(query);
for (let keyValue of searchParams) {
console.log(keyValue);
}
console.log('1',searchParams.getAll('ie')); // ["utf-8", "wtf"]
console.log('2',searchParams.get('tn')); // "baidu"
console.log('3',searchParams.getAll('tn')); // ["baidu"]
