You need to use a javascript function for this:

 Help with Code Tags 
 Javascript Syntax (Toggle Plain Text) 
function ChangeButtonStatus()
{
    if (document.getElementById("Text").value.length > 0)
    {
      document.getElementById("submit").disabled = false;
    }
    else
    {
      document.getElementById("submit").disabled = true;
    }
}
 
function ChangeButtonStatus()
{
    if (document.getElementById("Text").value.length > 0)
    {
      document.getElementById("submit").disabled = false;
    }
    else
    {
      document.getElementById("submit").disabled = true;
    }
}

Then in your form, add an OnBlur event to the textbox:

  <cfinput type="text" name="Text" id="Text" OnBlur="ChangeButtonStatus()">
  <cfinput type="text" name="Text" id="Text" OnBlur="ChangeButtonStatus()">
