Question

I just need the client-side JavaScript to be able to send a string value to the ASP.NET server app. What’s the common opinion on this process?

Answer 1

I’m assuming you don’t want to navigate away from the current page so, I would say to use an AJAX form post. Most javascript libraries have a simple method of doing so.

Your response can be a simple JSON object.

JavaScriptSerializer ser = new JavaScriptSerializer();
return ser.Serialize(new
{
    @success = true,
    @message = "some message"   
});
