Javascript Embedded In Html Not Running In Wkwebview

I am implementing wkwebview in an app that was using UIWebView. I am unable to get javascript to execute when pointing to a local html file that has the javascript embedded within

Solution 1:

You should be calling your javascript in this WKNavigationDelegate method, which is called when the webview finishes loading.

public func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
    webView.evaluateJavaScript("initMap()", completionHandler: { (value, err) in
        // Handle response here.
    })
}

Also, I'm not sure why you're calling two different webview.load() requests - maybe don't do that?
