How can i read the value of the callback message from a javascript call.
Here is my code:
private void OnDocumentLoaded(object sender, WebBrowserDocumentCompletedEventArgs e)
{
CallbackHandler callback = new CallbackHandler(EndRequestNormally, EndRequestWithNoData);
SendJavaScript(CreateRequestCompleteListenerScript());
theBrowser.Document.InvokeScript("RequestCompleteListener", new object[] { callback });
theBrowser.Document.InvokeScript("AjaxObjectHandle", new object[] { _parameters });
}
private void EndRequestNormally()
{
SetWebWidgetWindowSize();
}
private void SendJavaScript(string script)
{
theBrowser.Document.InvokeScript("eval", new object[] {script});
}
private string CreateRequestCompleteListenerScript()
{
StringBuilder script = new StringBuilder();
script.AppendLine("var RequestCompleteListener = function(callback) {");
script.AppendLine(" var internalCallback = {");
script.AppendLine(" handleCallback:function(message, params){");
script.AppendLine(" if (message == null){");
script.AppendLine(" callback.HandleNullMessage();");
script.AppendLine(" } else {");
script.AppendLine(" callback.HandleRequestComplete();");
script.AppendLine(" }");
script.AppendLine(" }");
script.AppendLine(" }");
script.AppendLine(" UpdateAjaxObject.addListener('requestcomplete', internalCallback.handleCallback, internalCallback);");
script.AppendLine("};");
return script.ToString();
}
[System.Runtime.InteropServices.ComVisible(true)]
public class CallbackHandler
{
public CallbackHandler(VoidHandler requestCompleteAction, VoidHandler nullMessageAction)
{
_requestCompleteAction = requestCompleteAction;
_nullMessageAction = nullMessageAction;
}
private VoidHandler _requestCompleteAction;
private VoidHandler _nullMessageAction;
private bool _requestCompleted;
[System.Runtime.InteropServices.DispId(0)]
public void HandleRequestComplete()
{
if (!_requestCompleted)
_requestCompleteAction();
_requestCompleted = true;
}
[System.Runtime.InteropServices.DispId(1)]
public void HandleNullMessage()
{
if (!_requestCompleted)
_nullMessageAction();
}
}
The above code is just making the call.
What i want is, to read the value in the message after the call.
The image below contains the values in the AJAX object
I want to get the count of the binshares under tradeschedule.
Is there a way to that?
Any help is appreciated.
Thanks
Do you mean you just want to get at it with JavaScript? <script>alert(AjaxObject.messages.tradeSchedule.binShares[0]);</script>
You didn't expand the binShares array so I'm not sure what's under there.
I see you made changes, you want the length of binShares, do this...
<script>alert(AjaxObject.messages.tradeSchedule.binShares.length);</script>
