disable field on fieldchange

AI generated answer (using internal Slack threads):

To disable a field on field change in NetSuite, you can use the

updateDisplayType

method in a User Event script or Client script. Here's how you can do it: In a User Event script, you can use the

beforeLoad

trigger and the

context.form

object to find a field by its id and then set

fieldObject.disabled=true

. Here's a sample code:

javascript
const button = context.form.getButton({id: buttonId});
if (!button) {
    return;
}
button.isDisabled = true;

In a Client script, you can use the

fieldChanged

function to disable a field when another field is changed. Here's a sample code:

javascript
function fieldChanged(context) {
    var currentRecordObj = currentRecord.get();
    var sublistId = context.sublistId;
    var fieldId = context.fieldId;

    if (sublistId === 'item') {
        var item = currentRecordObj.getCurrentSublistValue({
            sublistId: 'item',
            fieldId: fieldId
        });

        if (item) {
            currentRecordObj.setCurrentSublistValue({
                sublistId: 'item',
                fieldId: 'rate',
                line: lineNumber,
                value:'',
                ignoreFieldChange: true
            }).isDisabled=true;
        } else {
            currentRecordObj.setCurrentSublistValue({
                sublistId: 'item',
                fieldId: 'rate',
                line:lineNumber,
                value:'',
                ignoreFieldChange: true
            }).isDisabled=true;
        }
    }
}

Please note that the

isDisabled

property is not available for the

getCurrentSublistValue

and

setCurrentSublistValue

methods. You should use the

updateDisplayType

method to disable a field. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
