JavaScript: The Good Parts

Using JavaScript in the Platform

JavaScript can be used in a variety of ways:

Field Scripting - Add JavaScript code to take actions on a Field (On Change or On Focus)
Form Scripting - Add JavaScript code to a Form (On Load or On Save)
Post Selection JavaScript - Perform validations on Lookup Fields using JavaScript
Action buttons - Add action buttons when displaying a record
In a JSP/HTML Page - Make things happen on the client side to reduce the load on the server.
Toaster Message - Add custom messages in toaster using JavaScript.

Sample Code

Accessing Record Variables

You access record data using the Document Object Model (DOM). In the Sample Order Processing System, you might access a field in an OrderItem record like this:

var val = document.getElementById("item_quantity").valu; </syntaxhighlight>

Or, using Template:JQuery functions to shorten the syntax:

var val = $('input[name=item_quantity]').val(); </syntaxhighlight>

Accessing Variables in Lookup Records

Records in an object commonly have a Lookup to records in another object. For example, in the Sample Order Processing System, OrderItem records have a lookup to the Order they are part of, as well as lookup to the ProductInventory object, which holds details about the item the customer wants to order.

To access a field in the lookup target record, you use "dot notation", following this pattern:

{current_record_lookup_field}.{target_record_field} </syntaxhighlight>

For example, In an OrderItem record, then, you might get the quantity on hand like this:

var val = document.getElementById("related_to_productInventory.quantity_on_hand").valu; </syntaxhighlight>

Or, using Template:JQuery functions to shorten the syntax:

var val = $('input[name=related_to_productInventory.quantity_on_hand]').val(); </syntaxhighlight>

JavaScript Functions

Accessing Form Fields

JavaScript is a powerful language that can do many things. But one of it's most common uses is to dynamically modify the behavior of Forms, using Form Scripting and Field Scripting.

Note: To reference Form fields in JavaScript for the new AgileApps UI, see JavaScript Field Type Reference for New AgileApps User Interface.

Referencing the Current Form

In the HTML document object model (DOM), the current form is named _sdForm.
This line of code gets a reference to it and puts it in the form variable:

var form = _sdForm; </syntaxhighlight>

Accessing Fields in the Current Form

To find the name of a field in the platform:

Go to > Customization > Objects > {object} > Fields
Find the label of the field you're interested in
Get its name from the Field Name column
That name can then be used in the JavaScript code.

All fields can be accessed using the platform's JavaScript functions, as described in the Field Types section below. The most commonly accessed field types (TextField, TextArea, Date, DateTime, Time, and URL) can also be accessed using _sdForm[0]. For example, this line of code gets a reference to the first_name field, and puts it in the variable fName_field:

var fName_field = _sdForm[0].first_name; </syntaxhighlight>

Fields have two properties that you can access in JavaScript:

name: the name of the field
value: the value of the field

So this line retrieves the value of the field:

var fName = fName_field.value; </syntaxhighlight>

As does this longer version:

var fName = _sdForm[0].first_name.value; </syntaxhighlight>

Other fields can be accessed using the platform's JavaScript functions.
For a complete list, see the Field Types section below.

Updating Fields in the Current Form

The method used to update a field depends on the field type. All of the methods have the general form:

set...Value(_sdForm, field, value); </syntaxhighlight>

Below are some examples of common methods. (The section that follows contains a complete list.)

setTextFieldValue(_sdForm, "first_name", "Adam");

setPickListValue(_sdForm, "first_name", "Adam");

setMultiPickListValue(_sdForm, "first_name", ["new","closed"]);

   // value is an array of strings

setRadioButtonValue(_sdForm, "first_name", "Adam");

setCheckboxState(_sdForm, "first_name", true); // checked setCheckboxState(_sdForm, "first_name", false); // unchecked

setLookupValue(_sdForm, "project_number", "123456", "My Project");

   // where 123456 is the record ID of the target record 
   // "My Project" is the value of the record locator field(s) for that record

</syntaxhighlight>

Field Type Reference

Note: To view the field type reference in the new AgileApps user interface, see JavaScript Field Type Reference for New AgileApps User Interface.

The following table shows how to access and update the different field types, where:

_sdForm is the variable that references the current form
field is a string containing the name of the field
(as with all strings, literal values must be in quotes)
value is a value you specify (generally a string)
value is language keyword, typed exactly as shown--as in this line,
for example, which gets the value from a field called email_address:

_sdForm.email_address.value

Note:
Form data is in User Format. Data entered into the Form must be in that format, as well. Data going to and from the platform, on the other hand, must be in Database Format.

Accessing User Information

This function returns information about the logged-in user in a json object.

getUserDetails() </syntaxhighlight>

Values availble in the json object are:

id - user id
first_name - user's first name.
last_name - user's last name.
language - user's language code. (ex: en)
access_profile_name - user's access profile name.
time_zone_name - user's time zone name. (ex:America/Indianapolis)
time_zone_description - localized time zone description.
ex: (GMT-05:00) Eastern Standard Time (America/Indianapolis)
date_format - user's date format.
time_format - user's time format.
locale - user's locale code.
primary_team_name - user's primary team.
current_role_name - user's current role.
Can be empty if the user has a profile that allows global access, but does not play any specific role in the application.
roles - list of the user's roles in the current application, with current role first.
teams - list of teams the user belongs to, with the primary team name first.
userCustomFields - an object containing values for each custom field defined on the User object, where the access key is the field name

Example

This script prefills fields in current form with data for the logged-in user, where each user record has a custom field called customer_discount:

var userDetails = getUserDetails(); setTextFieldValue(_sdForm, "column_id", userDetails.id); setTextFieldValue(_sdForm, "first_name", userDetails.first_name); setTextFieldValue(_sdForm, "last_name", userDetails.last_name); setTextFieldValue(_sdForm, "language", userDetails.language); setTextFieldValue(_sdForm, "time_zone_name", userDetails.time_zone_name); setTextFieldValue(_sdForm, "time_zone_description", userDetails.time_zone_description); setTextFieldValue(_sdForm, "roles", userDetails.roles) ; setTextFieldValue(_sdForm, "discount", userDetails.userCustomFields.customer_discount); </syntaxhighlight>

Hiding Action Items and Assignment Buttons

Note: To apply these functions with the new AgileApps UI, see the section Considerations for Existing Custom Script Methods in JavaScript Field Type Reference for New AgileApps User Interface.

These functions can be used to hide the actions-menu-items and record-assignment buttons, by calling them from the On Load Script section of a Form Script.

hideActionsMenuItems

Hide one or more items in the ACTIONS menu:

hideActionsMenuItems(['value-1', 'value-2', ...]); </syntaxhighlight> where the parameter is an array of strings that contains the menu-item values (found by inspecting the value attribute of elements in the UI).

Example: hideActionsMenuItems(['assignOwnerShipButton','claimOwnerShipButton']);

The above example hides "assign to user" and "claim" options from actions menu.

hideClaimAndAssignButtons

Hide the Claim-record and Assign-record buttons.

hideClaimAndAssignButtons(['id-1', 'id-2', ...]); </syntaxhighlight> where the parameter is an array of strings which contains ID-attributes from the respective buttons.

Example: hideClaimAndAssignButtons(['assignOwnerShipButton','assignTeamOwnerShipButton','claimOwnerShipButton']);

The above example hides "assign to user", "assign to team" and "claim" buttons from owner pop-up.

Template Variables for Actions and Components

AJAX and REST

The combination of JavaScript and the platform's REST APIs lets you build a lot of power into a page that displays on a client-side browser.

About AJAX

AJAX is the name given to a set of JavaScript functions that let you connect to a server, get back data, and parse the data into something usable. It originally stood for "Asynchronous JavaScript and XML", but it can also use the JSON format for data interchange.

Perhaps the best summary of AJAX comes from the w3c.schools tutorial:

"AJAX is the art of exchanging data with a server, and updating parts of a web page, without reloading the whole page."

While an arbitrary string can be passed to or from the server, the two most popular formats by far are XML and JSON. The platform understands both, so you can choose the flavor you prefer. (A common variation is to send XML data to the platform because it's easy to build up strings in XML format, and then get JSON back because that is the easiest format to parse in JavaScript.)

Using AJAX in a Form

The jQuery functions included in the platform make it as simple as possible to make an AJAX call.

The code is expected to be executed as part of a Form, either as part of a Field Script or a Form Script. It builds up an XML string to send to a REST API. In this case, it creates the input XML required by the REST exec API, which executes a method in a Java class. And then tells the API to return JSON, which allows individual elements to be accessed by specifying little more than a JavaScript path.

For more information about using AJAX in a form, see the tech community article How to invoke a class from formscript using AJAX.

Using AJAX in a JSP Page

When you create a Page in the platform, you are creating a JSP page. You can embed Java code in that page, and use it to directly interact with the platform. Or you can use AJAX and the REST APIs, whichever is easiest.

For information on using AJAX in a JSP page, see the tech community article Invoking REST API Calls using AJAX in AgileApps Pages.

Example: Retrieving Data with a GET Request

To view the example on how to retrieve data using a GET request, see the tech community article Retrieving Data with a GET Request.

Example: Validating a CSRF session for POST, PUT, and DELETE

You have to validate a CSRF session for POST, PUT, and DELETE requests. For information about validating a CSRF session, see the Tech Community article at Validating a CSRF session for POST, PUT, and DELETE. This article provides sample codes for validating CSRF sessions for Form Submissions and REST APIs.

Note: Ensure to add the header X-XSRF-TOKEN with value of xsrfToken from the login response.

Example: Retrieving a JSON output of Dynamic Search API on a custom object

Note: This is applicable only for the legacy UI

To retrieve a JSON output of Dynamic Search API on a custom object, refer to this example:

var recordData = []; $.ajax({

        type: 'GET',
        url: '/networking/rest/record/cases?fieldList=subject,description&alt=json',
        processData: true,
        dataType: 'json',
        async:false,
        success: function(data)
        {

if (data.platform.record instanceof Array ) { recordData = data.platform.record ; } else if ( typeof data.platform.record != 'undefined' ) { recordData.push(data.platform.record); } alert(recordData); } }); </syntaxhighlight>
