The Action script field, on the Context Menu form, defines a script. The script runs when someone selects the context menu option.

This script is client-side and runs in the user's browser. The following JavaScript variables are available to the Action script when it is executed.

Table 1. Action script variables
VariableDescription
g_list GlideList2 against which the script runs.
g_fieldName Name of the field against which the context menu runs.
g_fieldLabel Label of the field against which the context menu runs.
g_sysId The sys_id of the row or form against which the script runs.
The base system uses the following code in an action script to refresh the platform view.
g_list.refresh(1);
Another example is the use of these variables in a list header menu to sort a list by the selected field in descending order (z to a).
g_list.sortDescending(g_fieldName);
