Kaizen# 209 - Answering Your Questions | All About Client Script


Hello everyone!

 

Welcome back to another exciting Kaizen post! Thanks for all your feedback and questions. In this post, let's see the answers to your questions related to Client Script.

We took the time to discuss with our development team, carefully reviewing all aspects, so we could bring you accurate and complete information firsthand.

Q1: Repeating the same validation code across Create, Edit, List, and Detail views reduces maintainability


Currently, this requirement is under analysis. For now, we suggest you use Static Resources to reduce duplication and improve maintainability.

Q2: A unified screen for writing client-side validation logic would improve efficiency, especially if it supports both validation and CRM data fetching


We are planning to provide a Client Script IDE with a tree structure listing all scripts. This will allow you to access a page’s complete script in a single view without exiting each time. This is part of future enhancements and as of now there is no ETA for this.


Q3: Client Scripts currently do not support access to third-party APIs

API calls can be made using HTTP requests or Connections.
Check out Kaizen#135: Third Party Integration using Client Script to see the implementation and a practical use case.
Also, our new ZRC support, now in early access, provides direct API calls for enhanced control and flexibility.


Q4: Need for deeper UI control in Client Scripts (like modifying metadata CSS and HTML)

Direct modification of CRM page CSS/HTML via Client Script is not possible. With a SlyteUI component, you can fully customize the CSS and HTML to fit your needs. SlyteUI is currently available in pilot access. Canvas offers limited styling options.


Q5: Canvas actions cannot trigger Blueprint transitions, limiting process automation

Blueprint transitions can now be initiated from Canvas pages. Click here for documentation.


Q6: Lack of functions to retrieve a field’s data type (text, boolean, datetime) limits dynamic handling
This feature is planned for future enhancements.


Q7: The onSave event is missing in Detail Page processing
While the Save action is not available on Detail pages, the onBeforeUpdate() field event can be used to enforce validations post-edit.
 

Q8: onChange does not work on multi-picklists and subforms

The development of onChange support for multi-select picklists  is completed and will get released very soon (in a week). The onCellChange() method is currently available for subforms.

Q9: Currently, there is no way to control or restrict access to the "Record detail page views" dropdown selector in Canvas detail pages based on user profiles or roles.

We are working on addressing this limitation and will keep you updated once the enhancement is available.

 

 

Q10: Why Zoho CRM provides too many ways for client validation? One is through Layout Validation->Setup, Layout Validation-Function, Client Script (ZDK). What is the major difference?

Feature

How It Works

Best For

Validation Rules
(no code)

Define conditions in the setup UI without coding. These checks run when you try to save a record. If conditions fail, the save is blocked and an error message is shown. Click here for more details.

Quick, straightforward validations like “Email must contain @domain.com” or “Amount cannot be negative,” especially for admins with no coding knowledge.

Layout rules
(no code)

Define layout rules that adjust the form UI in real-time based on field values. This includes showing/hiding sections, enabling/disabling fields, or making them mandatory. Click here for more details.

Use when the form sections needs to adapt dynamically to the context for pages other than Canvas (e.g., “If Customer Type = Business → Show GST details section”).

Functions (Deluge)

In Functions, you can write a Deluge script that executes server-side. Functions are usually triggered by workflows, buttons, schedules or record actions and can update fields, create related records, call external APIs and so on. Click here for more details.

Ideal for automating complex business logic and integrating with Zoho services or third-party applications.

Client Scripts (ZDK + JavaScript)

Use Zoho Developer Kit (ZDK) APIs with JavaScript to run logic directly in the browser. Triggers include On Load, On Field Change, On Save. You can block record save, fetch CRM/external data instantly, show dynamic messages, or modify field behavior and much more. Click here for more details.

Perfect for advanced, real-time validations and dynamic UI.
Example: Prefill address fields from an API, validate PAN instantly, or disable Save if multiple conditions fail.


In this Kaizen post, we have answered all your questions about Client Script, shared solutions along with relevant help doc links, and highlighted upcoming features and enhancements.  We hope this answers your queries and provides clarity on Client Script usage.

 

Happy Client Scripting!
