How to compare old and new values of a field in a client suitescript

AI generated answer (using internal Slack threads):

To compare old and new values of a field in a client SuiteScript, you can use the

oldRecord

and

newRecord

objects available in the script context of the event script. These objects represent the state of the record before and after the event, respectively. Here is a simple example of how you can compare old and new values:

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

    var oldValue = oldRecord.getValue('fieldname');
    var newValue = newRecord.getValue('fieldname');

    if (oldValue !== newValue) {
        // The field value has changed
    }
}

In a client script, you can use a global variable to store the old value of the field. You can set the initial value in the

pageInit

function and then compare or update it in the

fieldChanged

function. Here is an example:

javascript
var OLDVALS = {
    entity: '',
    trandate: '',
    status: '',
    location: ''
};

function pageInit(context) {
    var rec = context.currentRecord;

    Object.keys(OLDVALS).forEach(function (fieldId) {
        OLDVALS[fieldId] = rec.getValue(fieldId);
    });
}

function fieldChanged(context) {
    var fieldId = context.fieldId;
    var rec = context.currentRecord;

    if (Object.keys(OLDVALS).indexOf(fieldId) > -1 && rec.getValue(fieldId) !== OLDVALS[fieldId]) {
        // The field value has changed
    }
}

In this example,

OLDVALS

is a global object that stores the initial values of the fields. In the

pageInit

function, it sets the initial values. In the

fieldChanged

function, it checks if the field value has changed. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
