client script to set fields in page init

AI generated answer (using internal Slack threads):

Based on the conversations, it seems that you can use a client script to set fields in the

pageInit

function. This function is executed after the page is initialized. Here is an example of how you can do this:

javascript
/**
 * @NApiVersion 2.1
 * @NScriptType ClientScript
 * @NModuleScope SameAccount
 */
define([
    'N/record',
    'N/ui/message',
    'N/ui/dialog',
    'N/log',
    // other modules
],
function(Nrecord, NuiMessage, NuiDialog, Nlog, /* other modules */) {

    /**
     * Function to be executed after page is initialized.
     *
     * @param {Object} scriptContext
     * @param {Record} scriptContext.currentRecord - Current form record
     * @param {string} scriptContext.mode - The mode in which the record is being accessed (create, copy, or edit)
     *
     * @since 2015.2
     */
    const pageInit = (scriptContext) => {
        console.log('foo');
        alert('foo');
        Nlog.debug({
            title: 'pageInit',
            details: 'pageInit'
        });
        // other operations
    }

    return {
        pageInit: pageInit,
    };
    
});

In this example, the

pageInit

function is defined and then returned as part of the module's public API. This function will be executed when the page is initialized. You can add your logic to set fields inside this function. Please note that client scripts only work in Edit mode, not in View mode. If you want to do some DOM manipulation when viewing a record, you can use a

beforeLoad

UserEvent script that adds an inlinehtml field, then put the DOM manipulation code in that 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. ******
