Guide to transmitting data from a C# WinForm to a completely separate JavaScript client chat application

I am facing a challenge with my chat application where I have a client-side written in JavaScript and a server-side built using WinForms. My goal is to transfer a value from my FrmConsole.cs file to my converse.js file. Is there a method I can use to accomplish this task successfully? The communication between the client and operator console is established using the XMPP protocol, and an ejabberd server is utilized for this purpose. For instance, I need to send a specific string from my C# code to my JavaScript file:

private string GetStringValue()
{
  return "A string value";
}

The following snippet demonstrates the corresponding JavaScript code:

<script language="javascript" type="text/javascript>
  var stringValue = '<%=GetStringValue();%>';

  alert(stringValue);
</script>

Despite attempting this approach, I have not been able to generate the expected alert. Instead, the displayed content within the alert box is:

<%=GetStringValue();%>

Answer №1

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script type="text/javascript">
     function displayText(){
         var textValue = '<%=GetTextValue();%>';
         alert(textValue);
 </script>

main content:

 ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "Javascript", "javascript:displayText();", true);
