Detect window.open() from UIWebView

问题

Short question: Is it possible to detect window.open() in a UIWebView using the UIWebViewDelegate or is there another way to reach this? I need the the url when a window.open()-Event is fired to show a UIAlertView.

回答1:

You need to overwrite window.open() using JavaScript:

[webView stringByEvaluatingJavaScriptFromString:@"window.open = function (open) { return function  (url, name, features) { window.location.href = url; return window; }; } (window.open);"];

回答2:

Try using this delegate methods. Hope this helps.

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType;
- (void)webViewDidStartLoad:(UIWebView *)webView;
