您还可以使用 substring()函数从该位置开始返回子字符串:

You can also use the lastIndexOf() function to locate the last occurrence of the / character in your URL, then the substring() function to return the substring starting from that location:

console.log(this.href.substring(this.href.lastIndexOf('/') + 1));

那样，您将避免像split()那样创建包含所有URL段的数组.

That way, you'll avoid creating an array containing all your URL segments, as split() does.
