Like this:
For this example, we will ensure that a user does not enter a high impact into a cell to force them to open up the form view to do this:
function onCellEdit(sysIDs, table, oldValues, newValue, callback) { var saveAndClose = true; if (newValue == 1) { alert('High Impact cannot be set on a list view.'); saveAndClose = false; } callback(saveAndClose); }
This example uses the newValue parameter to check the value the impact has been set to. If it has high or 1 as the value of the field, which we need to use in scripts rather than labels, then the user is alerted through a message. By setting the saveAndClose variable to false, we can also stop the field from being updated. This is because the callback is using this variable, and therefore also sets the callback to false.
