JavaScript获取网页信息总结

JavaScript获取当前页面URL、title等，具体怎么用就看自己了～
由于本站用了伪静态，所以获取不到文档名.document.location.port;是获取URL关联的端口号码，thisHash = document.location.hash;是获取链接属性中在井号“#”后面的分段。

thisURL = document.URL;

thisHREF = document.location.href;

thisSLoc = self.location.href;

thisDLoc = document.location;

thisTLoc = top.location.href;

thisPLoc = parent.document.location;

thisTHost = top.location.hostname;

thisHost = location.hostname;

thisTitle = document.title;

thisProtocol = document.location.protocol;

thisPort = document.location.port;

thisHash = document.location.hash;

thisSearch = document.location.search;

thisPathname = document.location.pathname;

thisHtml = document.documentElement.innerHTML;

thisBodyText = document.documentElement.innerText;//获取网页内容文字
thisBodyText = document.body.innerText;//获取网页内容文字
