Writing to the debug log

To write to the debug log in your client-side JavaScript, or UI policies, make a call to the global function jslog().

An example of using jslog() in JavaScript:

function logData (r ) {
    lastLogDate  = r. responseXML. documentElement. getAttribute ( "last_log_entry" ) ; var items  = r. responseXML. getElementsByTagName ( "log" ) ;
    jslog ( "response=" + r. responseText ) ; }

Additionally, when client scripts run, the name of the client script and timing information is displayed. This can be useful in determining which scripts are running and whether they are impacting performance.

Debug UI policies

Enabling the glide.ui.ui_policy_debug property lets you monitor the processing of UI actions.

Here are some sample log events from an incident policy that sets fields to read-only if the incident_state is closed.

GlideFieldPolicy: Evaluating condition
GlideFieldPolicy:     incident_state (7) = 7 -> true
GlideFieldPolicy: --->>> TRUE
GlideFieldPolicy:    Setting opened_at disabled to true
GlideFieldPolicy:    Setting opened_by disabled to true
GlideFieldPolicy:    Setting closed_at disabled to true
GlideFieldPolicy:    Setting closed_by disabled to true
GlideFieldPolicy:    Setting company disabled to true

Access the JavaScript log

JavaScript that runs on the browser, such as client scripts, can include a call to jslog() to send information to the JavaScript Log. Users with the admin role can access this log.
