I am trying to register a javascript function that validates the prompts the user with a confirm message.  I get undefined (Jquery) and null (JavaScript) when trying to get the text box value.  I have attached the code.  Below is the code.  I have never tried this before.  I am registering the script in the code behind because I need to implement the code in an existing application.

Since you are injecting it from code-behind, you already have access to the TextBox. So you can change the get statement like:
document.getElementById('" + txtAPDateReceived.ClientID + "');")
