How to wait when page is loaded and then execute Javascript code in Android WebViewClient
0
I want processHTML to be triggered after the webpage is done loading. I think I need:
document.load =
for this. But I don't know the correct syntax for how to put it in loadUrl:
class JavaScriptTokenSubstractInterface {
@JavascriptInterface
@SuppressWarnings("unused")
fun processHTML(html: String) {
Log.d("","html shown is loading and not the result.")
}
}
val webView: WebView = findViewById(R.id.webView)
webView.settings.javaScriptEnabled = true
webView.settings.useWideViewPort = true
webView.requestFocus(View.FOCUS_DOWN)
webView.addJavascriptInterface(JavaScriptTokenSubstractInterface(), "HTMLOUT")
webView.webViewClient = object : WebViewClient() {
override fun onPageFinished(webView: WebView?, url: String?) {
super.onPageFinished(webView, url)
Thread.sleep(3000)
webView?.loadUrl("javascript:window.HTMLOUT.processHTML('<html>'+document.getElementsByTagName('html')[0].innerHTML+'</html>');")
}
}
webView.loadUrl("www.someWebPageThatIsLoading.nl")
What happens:
1. The loading of the page is shown
2. processHTML is triggered and it shows the HTML of the loading page
3. A few seconds go by and the page is done loading
processHTML should be triggered after the loading is done.
