Original Pull Request: https://github.com/langgenius/dify/pull/26249

State: closed
Merged: Yes

Overview

This PR adds missing type="button" attributes to button elements across the web application to prevent unwanted form submission behavior.

Problem

According to the MDN documentation, button elements without an explicit type attribute default to type="submit". This means that buttons intended for UI interactions can accidentally trigger form submissions when clicked, potentially causing:

  • Unexpected page reloads
  • Loss of current application state
  • Unintended data submission

Solution

Added type="button" attributes to all interactive UI buttons that are not intended for form submission. This explicitly declares their purpose and prevents the default submit behavior.

Files Changed

Updated 32 files across the codebase, including:

  • App management components: new-app-card.tsx, app-card.tsx
  • Workflow UI components: Schema editor buttons, tracing panel controls
  • Base UI components: Date pickers, audio controls, pagination, theme selector
  • Demo and test files: Service demo buttons and test components

Example Changes

Before:

<button className="..." onClick={handleClick}>
  Click me
</button>

After:

<button type="button" className="..." onClick={handleClick}>
  Click me
</button>

Testing

  • ✅ All existing tests pass (232 tests across 18 suites)
  • ✅ Button component tests specifically verified (18/18 passing)
  • ✅ No linting errors introduced
  • ✅ No functionality regressions detected

Impact

  • Zero breaking changes - all existing functionality preserved
  • Improved UX - prevents accidental form submissions
  • Better accessibility - explicit button behavior declaration
  • Follows web standards - aligns with MDN best practices

Resolves the issue by ensuring all interactive buttons have proper type declarations while maintaining full backward compatibility.

Description

add type="button"

Motivation

If your buttons are not for submitting form data to a server, be sure to set their type attribute to button. Otherwise, they will try to submit form data and to load the (nonexistent) response, possibly destroying the current state of the document.
