The content of this article is very simple. I will summarize some common commands for javascript to obtain current information.
console.info("document.URL=" + document.URL);
console.info("document.location.href=" + document.location.href);
//console.info("document.base=" + document.base); //This is wrong!
console.info("document.location=" + document.location);
console.info("self.location.href=" + self.location.href);
console.info("top.location.href=" + top.location.href);
console.info("location.hostname=" + location.hostname);
console.info("window.location.host=" + window.location.host);
console.info("window.location.pathname=" + window.location.pathname);
That's all I remember for the time being, I will update it later^_^
