encodeURIComponent
然后去decodeURIComponent

你可以嘗試一下非常簡短又好用的庫：query-string。

const queryString = require('query-string');
 
console.log(location.search);
//=> '?foo=bar'
 
const parsed = queryString.parse(location.search);
console.log(parsed);
//=> {foo: 'bar'}
 
console.log(location.hash);
//=> '#token=bada55cafe'
 
const parsedHash = queryString.parse(location.hash);
console.log(parsedHash);
//=> {token: 'bada55cafe'}
 
parsed.foo = 'unicorn';
parsed.ilike = 'pizza';
 
const stringified = queryString.stringify(parsed);
//=> 'foo=unicorn&ilike=pizza'
 
location.search = stringified;
// note that `location.search` automatically prepends a question mark
console.log(location.search);
//=> '?foo=unicorn&ilike=pizza'
