Question

I’m trying to load an HTML page that has text fields into a webview, edit the text in text fields and then get the HTML data in that webview.

I’m using this code to load the page:

NSString* path = [[NSBundle mainBundle] pathForResource:@"file" ofType:@"htm"];
NSData* xmlData = [NSData dataWithContentsOfFile:path];
[web loadData:xmlData MIMEType:@"text/html" textEncodingName:nil baseURL:nil];

And this code to get the content and set it again in the webview:

NSString *myText = [web stringByEvaluatingJavaScriptFromString:@"document.all[0].innerHTML"];
data = [myText dataUsingEncoding:NSUTF8StringEncoding];
[web loadData:data MIMEType:@"text/html" textEncodingName:nil baseURL:nil];

The problem is that the text I inserted in the text field is not being returned from the webview.

I tried document.body.innerHTML and document.body.outerHTML, they all return the HTML page data the way I loaded it.

Is there anyway to get the HTML page data that includes text I inserted there?

Try using stringByEvaluatingJavaScriptFromString. If you are using jquery, you should be able to use an expression that returns the value of your textfield, i.e.:

NSString* text = [webView stringByEvaluatingJavaScriptFromString:@"$('#myTextFieldId').val();"];
