最近一直在做混合開發，經常遇到一些靜態網頁，需獲取網頁的標題等操作，可以用下面方法

還有，注意webview的代理方法

 - (void)webViewDidFinishLoad:(UIWebView *)webView 

網頁前進和回退都會呼叫

- (void)viewDidLoad {

[super viewDidLoad];

NSString *[email protected]"http://baidu.com";

UIWebView *web = [[UIWebView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

web.delegate = self;

[web loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:strurl]]
 
];

[self.view addSubview:web];

// Do any additional setup after loading the view, typically from a nib.

}

- (void)webViewDidFinishLoad:(UIWebView *)webView {

UIWebView *web = webView;

//獲取所有的html

NSString *allHtml = @"document.documentElement.innerHTML";

//獲取網頁title

NSString *htmlTitle = @"document.title"
 
;

//獲取網頁的一個值

NSString *htmlNum = @"document.getElementById('title').innerText";

//獲取到得網頁內容

NSString *allHtmlInfo = [web stringByEvaluatingJavaScriptFromString:allHtml];

NSLog(@"%@",allHtmlInfo);

NSString *titleHtmlInfo = [web stringByEvaluatingJavaScriptFromString:htmlTitle];

NSLog(@"%@",titleHtmlInfo);

NSString
 
 *numHtmlInfo = [web stringByEvaluatingJavaScriptFromString:htmlNum];

NSLog(@"%@",numHtmlInfo);

}
