推荐答案

我知道这个问题已经问了很久了，但是尽管有很多意见并且没有明确的答案，我还是决定提供这个答案:

I understand that the question has been asked for a long time ago, but despite the large number of views and the absence of an plain answer, I decided to offer this answer:

假设会话变量的注册方式类似于/index.php?PHPSESSID=9ebca8bd62c830d3e79272b4f585ff8f

Assume that the session variable is registered like /index.php?PHPSESSID=9ebca8bd62c830d3e79272b4f585ff8f

在这种情况下，您可以通过JS对象"location"获取变量PHPSESSID并通过Ext.Object.fromQueryString()对其进行转换

In this case, you can get the variable PHPSESSID through JS object "location" and transform it through Ext.Object.fromQueryString()

所以:

console.log( Ext.Object.fromQueryString( location.search ) );

将根据您的需要准备PHPSESSID变量.

will prepare PHPSESSID variable for your needs.
