iOS-07-iOS获取UIWebView中的网页信息

JavaScript获取网页信息总结JavaScript获取当前页面URL、title等，
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

举个例子

获取所有
html:NSString *lJs = @"document.documentElement.innerHTML";
获取网页
title:NSString *lJs2 = @"document.title";
UIWebView *lWebView = [self getCurrentWebView];
NSString *lHtml1 = [lWebView stringByEvaluatingJavaScriptFromString:lJs];
NSString *lHtml2 = [lWebView stringByEvaluatingJavaScriptFromString:lJs2];
在实际用途中 在webView的代理中使用，当webView加载完成时获取网页信息保存成NSString，过滤文字信息，可以重新加载webView。
