I am using UIWebView to load a URL.

Inside the page of that URL, it uses alert("whatever msg") as JavaScript. My UIWebView will pop up a window and show that alert message.

Is there a way to disable this kind of popup window or JavaScript alert window?

                [].slice.apply(document.querySelectorAll('iframe')).forEach(function(n){if(n.contentWindow != window){n.contentWindow.alert=n.contentWindow.confirm=n.contentWindow.prompt=function(n){}}})
                """
    webView.evaluateJavaScript(script, completionHandler: nil)
