this is my button

`<button type="button" class="btn btn-success btn-lg" value="Calculate" onclick="ageCalculate()">Calculate</button>`

i want to do something when button Calculate is clicked..

i have tried this method but did not work..

`

 func webView(_ webView: WKWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebView.NavigationType) -> Bool {
            
        if (navigationType == .formSubmitted) {
               
            print("Button Clicked in the app")

        
            }
            return true
        }
    `

when i change UIWebView.NavigationType to WKWebview then i got this error..

Reference to member 'formSubmitted' cannot be resolved without a contextual type

  • UIWebView and WKWebView are 2 different things and are not interchangeable. UIWebView is deprecated and should not be used. And WKWebView doesn't have such event. You should communicate via JS evaluation or messages, check post I link below Commented Apr 10, 2023 at 16:10
