Definition

interface BreakWhileConfig

Field structure

Field	Type	Required	Description
onBreak	((event: BreakEvent) => void | Promise<void>) | undefined	Optional	Read-only. Called before the reason is thrown; its errors are swallowed and promises are not awaited.

Examples

• Rejection checks, first match, and sequential processing: Use real lists to express multiple checks and enumerated dispatch; a single ordinary condition can still use if.

One explicit rejection

Beginner · Node.js

TypeScript

import { Support } from '@jangts/agent-core';
const input = '你好';
Support.breakWhile(!input.trim(), '问题不能为空');
console.log(input);

JavaScript

import { Support } from '@jangts/agent-core';

Support.breakWhile(!input.trim(), '问题不能为空');
