can we show ui/message in user event script before load event

AI generated answer (using internal Slack threads):

Yes, you can show a UI message in a User Event script before the load event. However, it requires a combination of User Event and Client scripts. In your User Event script's

beforeLoad()

function, you can include a Client Script using the following code:

javascript
if(runtime.executionContext == runtime.ContextType.USER_INTERFACE)
    context.form.clientScriptModulePath = ‘path/to/your/client/script’;

Then, in your Client Script, you can adjust the content of the HTML field. You can make the default value of the inlineHTML something like

<div id="fill_this_in_on_page_load"></div>

, and then your client script would have something like

jQuery('#fill_this_in_on_page_load').html('here is my fancy HTML');

. Here is an example of how you can call a client script in a User Event script:

javascript
/**
 *@NApiVersion 2.x
 *@NScriptType UserEventScript
 */
define(['N/record', 'N/ui/serverWidget'],
    function (record, ui) {
        function beforeLoad(context) {
            try {
                if (context.type != 'view') return;

                var inline = context.form.addField({
                    id: 'custpage_trigger_it',
                    label: 'not shown',
                    type: ui.FieldType.INLINEHTML,
                });
                inline.defaultValue = "<script>jQuery(function($){ require(['/SuiteScripts/SampleScriptName'], function(mod){ console.log('loaded'); mod.showMessage();});});</script>";
            } catch (e) {
            }
        }


        return {
            beforeLoad: beforeLoad
        };
    });

Please note that setting values is only allowed in

beforeLoad

when the record is created.

setValue

is ignored when editing a record in

beforeLoad

. If you need to set a value when the page is loaded, you can use a Client Script with the

pageinit

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