I am using webview to load a url, after loaded, it has some html element, are generated or value are assign during run time or after document has finished loaded. And I couldn't get the element value at run time...
Because i need to use javascript to run some javascript function which function already defined in the website.
But i noticed that cannot be done using EvalScipt.
Eg.
NavigationTask nv = null;
nv = eoWebControl.WebView.LoadUrl(url);
nv.WebView.LoadCompleted += WebView_LoadCompleted;
webReq = new Request(url);
void WebView_LoadCompleted(object sender, LoadCompletedEventArgs e)
{
if (e.Task.IsDone())
{
MessageBox.Show("load completed: " + e.Url.ToString());
}
}
private void btnGetEle_Click(object sender, EventArgs e)
{
string getEleJs = @"document.getElementById('myframe').contentDocument.embeds[0];";
object obj = eoWebView.EvalScript(getEleJs); // this return EO.WebBrowser.JSUndefined
}
the html document look as follow
<html>
<head>
<title></title>
</head>
<body>
<frameset>
<frameset>
<frame id="myframe">
<body>
<div>
<object>
<param ..... />
<param ..... />
<param ..... />
<param ..... />
<embed src="" />
</object>
</div>
</body>
</frame>
</frameset>
</frameset>
</body>
</html>
