explain fieldChanged and postSourcing

AI generated answer (using internal Slack threads):

fieldChanged and postSourcing are two different types of event handlers in SuiteScript, NetSuite's JavaScript-based API. fieldChanged is an event that is triggered when a field value changes. This event is useful when you want to perform some action based on the change in a field's value. However, it's important to note that this event will fire for any field change, so you may want to add conditions to isolate the event to occur only when a specific field is changed. For example, you can check the field id before executing your logic. Also, be aware that calling

setValue

inside a

fieldChanged

event will trigger the

fieldChanged

event again, potentially causing an infinite loop. To avoid this, you can use the

ignoreFieldChange

parameter of

setValue

.

code
function fieldChanged(scriptContext) {
    if (scriptContext.fieldId === 'your_specific_field') {
        // Your logic here
    }
}

postSourcing is an event that is triggered after a field sourcing operation is complete. This event is useful when you want to perform some action after a field's value has been sourced from another record. For example, you might want to set another field's value based on the sourced value. However, be careful when calling

setValue

inside a

postSourcing

event, as it can also trigger the

postSourcing

event again, potentially causing an infinite loop. To avoid this, you can use the

ignoreFieldChange

parameter of

setValue

.

code
function postSourcing(scriptContext) {
    if (scriptContext.fieldId === 'your_specific_field') {
        var currentRecord = scriptContext.currentRecord;
        currentRecord.setValue({
            fieldId: 'another_field',
            value: 'new_value',
            ignoreFieldChange: true
        });
    }
}
