javascript - How do I determine the input field the user has selected from a web page downloaded from a server

Question

I have tried the following with no success, any help will be appreciated.

UIPasteboard *pb = [UIPasteboard generalPasteboard];

[pb setString:passwordName];

NSString *jScriptString;

jScriptString = [NSString stringWithFormat:@"var output = {document.getElementById;" " ;output.innerHTML = document.activeElement.value = '%@'}",  passwordName];


[self.viewWebSite stringByEvaluatingJavaScriptFromString:jScriptString];

只是在这里猜测，但是当您 uiwebview 加载页面时，您可以添加一个 .js 文件，该文件位于您的 ios 应用程序的本地，为 dom 中的每个输入字段添加一个 onfocus 方法。然后你可以让 onfocus 事件通过 window.location 属性将元素 id 传递给 iOS，webView:shouldStartLoadWithRequest:navigationType: 可以监控。
