js，如何在location.hash中获得一个部分

Question

我希望获得location.hash部分，即%20之后的单词。但是怎么样？

解释

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;

Answer 2

首先使用unescape功能。之后，您可以执行正则表达式replace。

var url = "http://localhost/text/search.php?search=2011%20best%20and%20worst";
alert (unescape(url).replace(/^\S* /,""));
