I want to access the http response headers for all the http requests of this page so that I can determine their status.

例如第一个脚本请求的响应头和随后的其他脚本。

换句话说，我想算不上。响应状态为错误的请求。

Answer 1

试试这个：

var req = new XMLHttpRequest();
req.open('GET', document.location, false);
req.send(null);
var headers = req.getAllResponseHeaders().toLowerCase();
alert(headers);
