Syntax
formContext.getControl(arg).getAttribute();
Return Value
Type: Object
Description: A column
Remarks
The constituent controls within a quick view control are included in the controls collection and these controls have the getAttribute method. However, the column is not part of the column collection for the table. While you can retrieve the value for that column using getValue and even change the value using setValue, changes you make will not be saved with the table.
The following code shows using the value the contact mobilephone column when displayed on an account form using a quick view control named contactQuickForm. This code hides the control when the value of the column is null.
var quickViewMobilePhoneControl = formContext.getControl("contactQuickForm_contactQuickForm_contact_mobilephone");
if (quickViewMobilePhoneControl.getAttribute().getValue() == null) {
quickViewMobilePhoneControl.setVisible(false);
}
