Question

I am showing a web page using html string in a UIWebview. I want to retrieve the value typed from the below text area code.

result = [result stringByAppendingFormat:@"<textarea name=\"qId_"];
    NSString *questionid = [question valueForKey:@"QuestionId"];
    NSString *questionidSTR = (NSString *) [NSString stringWithFormat:@"%@", questionid];
    result = [result stringByAppendingFormat:questionidSTR];
    [questionidArray addObject:questionidSTR];
    result = [result stringByAppendingFormat:@"\" rows=\"5\" style=\"width:90%\"></textarea>"];

I tried

NSString  *value = [NSString stringWithFormat:@"%@%@%@",@"document.getElementById('",[questionidArray objectAtIndex:i],@"').value"];

   NSString* out = [enterSurveyWebview stringByEvaluatingJavaScriptFromString:value];

But, its not giving the correct output, i think i’m doing wrong when retrieving the value.

Could someone please correct me for retrieving portion?

Thank you.

Your <textarea> has a name of qId_%@ (where %@ is the QuestionId), but your javascript is only asking for %@. You also need to be using getElementByName() instead of getElementById().

NSString *value = [NSString stringWithFormat:@"document.getElementsByName('qId_%@')[0].value", [questionidArray objectAtIndex:i]];
