Tutorial  [3/8]: VFP-Diagnostics: Development

[<<  <  >  >>]     view the code

Here is an example of Permanent VF-Diagnostics (abbreviated 'vfpd' or 'vfp-diagnostics') in a development environment.

What is your favorite integer between 8 and 20?
[vfpd on]

Unless vfp-diagnostics are on (or 'activated'), the JavaScript code for it is not downloaded. When the '[vfpd on]' link is visible, vfp-diagnostics are off.

Printing out the closing 'form' tag ('</FORM>') within the SCRIPT block prevents empty lines from being printed in the vfpd-toolbar's place (when off/not displayed).
