Hi,

You would just load the page into the WebView, then use WebView.EvalScript to fill in the user name and password textbox and submit the login form. Basically, you need to do the same thing the end user is doing through JavaScript.

Please keep in mind that this is not always possible. It is very common that a web page would use a CAPTCHA to detect whether it is really a human to log into the page. If that's the case and you try to automate the process using JavaScript, then most likely you will fail the CAPTCHA test. This is the intended result because the very reason the site author place a CAPTCHA on the page is to stop you from automating the page.

Thanks!

I want to do with this site

Quote:
webView3.EvalScript("document.getElementById('txtUsername').value='user_name';");


i see this error
EO.WebBrowser.JSInvokeException: 'EvalScript failed because script engine is not ready or is shutdown before the script can finish. Please use EvalScriptAsync instead of EvalScript to execute JavaScript code in this case.'

Hi,

If your application is based on .NET 4.6 and newer, you can try to use EvalScriptAsync instead:

https://www.essentialobjects.com/doc/eo.extensions.webviewextensions.evalscriptasync__1_overload_1.html

You will need to reference EO.Extensions.dll in order to use this method.

Thanks!

Hi,

You can just do something like this:

Code: C#
await webView3.EvalScriptAsync(@"
document.getElementById('txtUsername').value='user_name';
document.getElementById('txtPassword').value='password';
document.getElementById('ext-gen22').click();
");


The third line clicks the button.

Thanks!
