New to NetSuite | Client Script: lineInit(scriptContext)

After discussing all the types of SuiteScript in the New to NetSuite | SuiteScript Types Overview article, we are now focusing on the different types of Client Script. The lineInit function is specifically designed to handle actions when an existing line item is selected or initialized within a transaction form. It's a useful event for setting default values, enabling, or disabling fields, or performing any line-specific logic that needs to occur each time a line is accessed.

Basic Structure of a fieldChanged Script

Here’s a basic example of a fieldChanged script:

/**
 * @NApiVersion 2.x
 * @NScriptType ClientScript
 * @NModuleScope SameAccount
 */
define(['N/error','N/currentRecord'],
	
function(error,currentRecord) {
      /**
     * Function to be executed when field is changed.
     *
     * @param {Object} scriptContext
     * @param {Record} scriptContext.currentRecord - Current form record
     * @param {string} scriptContext.sublistId - Sublist name
     * @param {string} scriptContext.fieldId - Field name
     * @param {number} scriptContext.lineNum - Line number. Will be undefined if not a sublist or matrix field
