View Display Expression Technical Reference
A page that contains a view is displayed in an operator’s Web browser. The view contains data that is loaded from the
server dynamically. Because of this, both data formatting and display operations for the view are implemented with
JavaScript in the Web browser.
For each item displayed in the view, a JavaScript object is constructed. Each field of the item is defined as a property
of this object. When evaluating the JavaScript Display Expression, the data variable is used to refer to this object.
Thus, the expression data.my_field would return the value of the field named “my_field”.
In the above view (the guest_users view), the four columns displayed correspond to the username, role_name,
enabled, and expire_time fields.
Value Description
Display Expressions
data.username.bold() Displays the username string as bold text.

Nwa_BooleanText(data.enabled, "Enabled",
"Disabled")

%H:%M") : "N/A"
