iphone - Getting data from uiwebview textfield

Am developing an app which load a HTML page into uiwebview - that html file contains text-filed and drop-down list, text-boxes etc..

Here How to get values which user has entered in that text-filed and answers selected from drop-down(picker).

Thanks

Answer

You can use [UIWebView stringByEvaluatingJavascriptFromString:] method and get the values by executing the javascript.

Example: If your html is:

<html>
  <body>
      <input id="myId" type="text" value="TextValue"/>
  </body>
</html>

Following code can get you the value of the text field:

   NSString* value = [webView stringByEvaluatingJavaScriptFromString:@"document.getElementById('myId').value"];
