Debugging Ajax applications
ColdFusion provides a set of JavaScript functions that log information to a pop-up display window. ColdFusion also
logs many standard client-side activities to the window.
Display logging information
To display the logging window you must do the following:
Enable ColdFusion to send information to the logging window
1
2
Request logging window information in the main CFML page request.
Enable logging output
To enable ColdFusion to send information to the logging window, do the following:
• Select the Enable Ajax Debug Log Window option on the ColdFusion Administrator > Debugging & Logging >
Debug Output Settings page. To view exception messages in the logging window, select the Enable Robust
Exception Information option on the Debug Output Settings page.
• Make sure that the IP address of the system where you do the debugging is included on the ColdFusion
Administrator > Debugging & Logging > Debugging IP List page of the ColdFusion Administrator. By default this
list includes only 127.0.0.1.
Display logging information for a page
To display the logging window when you request a CFML page in the browser, specify an HTTP parameter of
in the URL when you request a page, as in the following URL:
http://localhost:8500/myStore/products.cfm?cfdebug
After the debug log window appears, it continues running until you navigate to a new page in the browser. The logging
window includes options that let you filter the messages by either or both of the following criteria:
• Severity
• Category
You can select to display logging information at any combination of four levels of severity: debug, info, error, and
window. The specific logging function that you call determines the severity level.
The logging window always displays options to filter the output by using standard categories: bind, global, http,
LogReader, and widget. (For information on these categories, see
page 885.) It also displays a filter option for each custom category that you specify in a ColdFusion logging call.
ColdFusion does not limit the number of categories you create, but create only as many categories as you require to
debug your application effectively.
