javascript - js，如何获取location.hash中的一部分

Question

我想获取location.hash部分，即第一个%20之后的单词。但如何呢？

解释一下

http://localhost/text/search.php?search=sweet%20girl  => girl
http://localhost/text/search.php?search=fashion  => NULL
http://localhost/text/search.php?search=2011%20best%20and%20worst => best and worst

Answer 1

var s = decodeURIComponent(location.search);
var index = s.indexOf(" ");
s = index === -1 ? s.substr(index + 1) : null;
