I'm using a WKWebView with a Javascript to add items to the webpage, like so:
<!-- test.html -->
<!doctype>
<html>
<head>
<script type="text/javascript">
function addLogItem() {
document.getElementById("logItems").innerHTML += "New log item<br>"
}
</script>
</head>
<body>
<div id = "logItems"> Log items:<br> </div>
</body>
</html>func viewDidLoad() {
webView.navigationDelegate = self
let url = Bundle.main.url(forResource: "test", withExtension: "html")!
webView.load(URLRequest(url: url))
}
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
webView.evaluateJavaScript("logItems()") { _, _ in
self.webView.evaluateJavaScript("document.body.innerHTML") { result, _ in
print(result!) // Prints correct HTML data, with added "New log item<br>" line
}
}
}The first evaluateJavaScript call invokes the addLogItem Javascript method, the second one confirm the new log item has been added on the HTML page.
However, the WKWebView in the view controller doesn't update and doesn't show the line added line.
How do I get WKWebView to show the new updated content?
