UIWebView not calling stringbyAppendingJavascript function

Question

I have a UIWebView that loads a website. Then in

- (void)webViewDidFinishLoad:(UIWebView *)webView

I try to run the function

[webView stringByEvaluatingJavascript:@"myFunction();"];

but it doesn't work it does nothing.

I have but this under a button as well and at first it does nothing.

but when I tap the UIWebView and press the button it works fine.

Has anyone got any ideas why this isn't working?

Try calling alert() to make sure the problem isn't in your javascript function. If you are able to see the popup box you will know the problem lies in your javascript, and not in the UIWebView.

This has helped thanks. It turned out I had a bit of javascript to help other browsers on button click performance, but it stop me on safari clicking completely

Make sure that your HTML page is including the file with that function and the base URL of your webview is correctly set.

edit oops ignore the first half if it works with a button. Second half still applies.
