please write a client script that runs on a suitelet, which raises an error message if field custpage_myfield has less than 5 characters entered in it and will not allow the user to proceed to next field

AI generated answer (using internal Slack threads):

Based on the conversations provided, here is a sample client script that runs on a suitelet. This script raises an error message if the field

custpage_myfield

has less than 5 characters entered in it and will not allow the user to proceed to the next field:

javascript
define(['N/ui/message', 'N/currentRecord'], function(message, currentRecord) {
    function fieldChanged(context) {
        if (context.fieldId === 'custpage_myfield') {
            var currentRec = currentRecord.get();
            var fieldValue = currentRec.getValue({
                fieldId: 'custpage_myfield'
            });
            if (fieldValue.length < 5) {
                var myMsg = message.create({
                    title: "Input Error",
                    message: "Field 'custpage_myfield' must have at least 5 characters",
                    type: message.Type.ERROR
                });
                myMsg.show();
                currentRec.setValue({
                    fieldId: 'custpage_myfield',
                    value: ''
                });
            }
        }
    }
    return {
        fieldChanged: fieldChanged
    };
});

This script uses the

fieldChanged

entry point to check the length of the value entered in the

custpage_myfield

field. If the length is less than 5, it creates an error message and clears the field value. Remember to set this client script in your suitelet form using

form.clientScriptModulePath = 'path_to_your_script';
