my JS fails to get contents of a div in Objective-C
Question
I am managing to retrieve some text from my Webview. Here is a example of what my HTML file looks like.
Template.html:
<html>
<body>
<div id="content" contenteditable="true" style="font-family: Helvetica">
hello
</div>
</body>
</html>
(The code above is exactly all I have in my template.html file.)
Then I run:
NSString *js = @"document.getElementById('content').innerHTML";
NSString* html = [panel stringByEvaluatingJavaScriptFromString:js];
It returns NOTHING! Is Xcode stopping to support this type of JS?
Please help, thanks a lot!
---------EDIT------------ For more information, this is how I load my page:
NSBundle *bundle = [NSBundle mainBundle];
NSURL* temp = [bundle URLForResource:@"template" withExtension:@"html"];
[panel loadRequest:[NSURLRequest requestWithURL:temp]];

What I discovered at last is in fact an issue of UIWebViewDelegate!
-(void)webViewDidFinishLoad:(UIWebView *)webView{
NSString *js = @"getContent();";//This function is used to get
//the innerHTML of the document.
NSString* html = [panel stringByEvaluatingJavaScriptFromString:js];
L22(@"content HTML:",html);
}
This will give me the text within my div.
