如何在不使用 JS 发出新请求的情况下读取当前标头?
可能重复:
在 Javascript 中访问 HTTP 标头?
我知道用 javascript 读取当前标题的唯一方法是:
The only way what i know to read with javascript the current headers is:
var req = new XMLHttpRequest();
req.open('GET', document.location, false);
req.send(null);
var headers = req.getAllResponseHeaders().toLowerCase();
但我不想发出新请求，我想读取当前标头.
But i don't want make a new request, i want read the current headers.
这可能吗?谢谢！
推荐答案
不发送ajax请求，无法通过Javascript访问页眉.
It's not possible to access page headers via Javascript, without sending ajax request.
