設置錨的href屬性時，相對URL更改為絕對URL

Question

var a = document.createElement('a');
a.href = '/path';

// will give the absolute url: http://.../path
console.log(a.href);

a.href是否有可能在不修改返回值的情況下返回原始相對路徑'/ path'？

Answer 1

這應該做到-

var a = document.createElement('a');
a.href = '/path';

var domain = window.location.origin;
console.log(a.href.substring(domain.length));
