hi, what is the best approach to wait for page to finish loading once i perform javascript click?

Quote:
webview.LoadUrlAndWait(url);
webview.EvalScript("document.getElementById('continue_button').click();");


also, is there also a way how to wait until a certain element is available? (exists in html)

thanks in advance

Hi,

There is no fixed method for you to wait for this kind of wait because a button click can trigger any kind of action. One way to achieve what you want is to install a callback in your new page's JavaScript code and then wait for that callback code to be invoked. Inside your callback function you can call into .NET code to proceed further. This means that you will need to change your code structure from an synchronous wait to an asynchronous callback fashion. You can find more information on how to call into .NET code from JavaScript code here:

Thanks!
