Best way to compare the old and new record in a user event

AI generated answer (using internal Slack threads):

The best way to compare the old and new record in a user event is to use the

scriptContext.oldRecord

and

scriptContext.newRecord

objects in SuiteScript 2.0. These objects are of type

record.Record

and you can use methods like

Record.getValue

to get the value of a field from one to compare to the other. Here is a simple example:

javascript
function afterSubmit(scriptContext) {
    var oldRecord = scriptContext.oldRecord;
    var newRecord = scriptContext.newRecord;

    var oldFieldValue = oldRecord.getValue({fieldId: 'your_field_id'});
    var newFieldValue = newRecord.getValue({fieldId: 'your_field_id'});

    if(oldFieldValue !== newFieldValue) {
        // The field value has changed
    }
}

In SuiteScript 1.0, you can use

nlapiGetOldRecord

and

nlapiGetNewRecord

to get the old and new record respectively. When comparing date fields, make sure to compare the time values of the date objects, not the date objects themselves. For example, use

newDateObj.getTime() === oldDateObj.getTime()

, not

newDateObj === oldDateObj
