Client-Side Scripting Design and Processing

Client Scripts: Enhance user experience by reducing
form completion time.
Form Load: Ensure proper client-side processing by
loading forms first.
Field Control: Use methods like disabling list editing,
business rules, and data policies to manage field
values.
Minimize Server Lookups: Utilize g_scratchpad for efficient data transfer from server to client, avoiding performance-heavy methods like GlideRecord.
“Asynchronous GlideAjax: Dynamically request server data,
improving performance.”

Client-Side Scripting Design and Processing

Use setValue() Correctly: Include the display
value to prevent unnecessary server calls.
Prefer UI Policies: They offer better control and do not require scripting.
Input Validation: Use client scripts to validate user input before submission.
Script Order: Control execution order to prevent conflicts

Client-Side Scripting Design and Processing
Avoid DOM Manipulation: Use GlideForm API for maintainability.
Global Client Scripts: Limit their use to avoid performance issues.
Encapsulate Code: Wrap code in functions to manage variable scope.
Run Necessary Scripts: Optimize scripts to execute
only when needed, using flags like isLoading and newValue checks.
