直接从 JavaScript 访问 GET?

问题描述

我想我可以使用 PHP 从 JavaScript 访问 $_GET 变量:

I suppose I could use PHP to access $_GET variables from JavaScript:

<script>
var to = $_GET['to'];
var from = $_GET['from'];
</script>
<script src="realScript" type="text/javascript"></script>

但也许更简单.有没有办法直接从JS做到这一点?

But perhaps it's even simpler. Is there a way to do it directly from JS?

推荐答案

看

window.location.search

它将包含这样的字符串:?foo=1&bar=2

It will contain a string like this: ?foo=1&bar=2

要将其转化为对象，您只需要进行一些拆分:

To get from that into an object, some splitting is all you need to do:

var parts = window.location.search.substr(1).split("&");
var $_GET = {};
for (var i = 0; i < parts.length; i++) {
    var temp = parts[i].split("=");
    $_GET[decodeURIComponent(temp[0])] = decodeURIComponent(temp[1]);
}

alert($_GET['foo']); // 1
alert($_GET.bar);    // 2
