Why the Ajax script is not running on IIS 7.5 Win 2008 R2 server?
How to debug AJAX calls
The full answer is spread across the comments on OP's question but I think this one helped the most:
- Go to the web page which makes the AJAX call
- In Chrome press F12
- Go to the Network tab
- Activate the AJAX call by submitting the form #reservSearch
- In the Network tab look for a call to /Home/GetRates
- Click it
- Check the Preview and Response tabs to see the output from your server
- Is it displaying the expected HTML data which your AJAX call is listening for?
