直接从JavaScript访问？ [英] Access GET directly from JavaScript?

问题描述

我想我可以使用PHP来访问JavaScript中的 $ _ GET 变量：

 <脚本> 
 var to = $ _GET ['to']; 
 var from = $ _GET ['from']; 
< / script> 
< script src =realScripttype =text / javascript>< / script> 
  

但也许它更简单。有没有办法直接从JS做到？

  window.location.search 
  

它包含一个字符串是这样的：？foo = 1& bar = 2

是你需要做的：

  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 
  

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>

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

解决方案

Look at

window.location.search

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

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
