#鸿蒙通关秘籍#大家好，ArkUI中ArkTS工具类怎么获取，有谁知道不？

哈哈，ArkUI中获取TS工具类，你可以使用@arkts.utils工具类，它会提供一系列有用的工具方法。

import { lang } from '@kit.ArkTS';
import { collections } from '@kit.ArkTS';

type ISendable = lang.ISendable;
let jsonText = '{"name": "John", "age": 30, "city": "ChongQing"}';
let obj = `ArkTSUtils.ASON.parse(jsonText)` as ISendable;
console.info((obj as object)?.["name"]);
// 期望输出: 'John'
console.info((obj as object)?.["age"]);
// 期望输出: 30
console.info((obj as object)?.["city"]);
// 期望输出: 'ChongQing'

let options: `ArkTSUtils.ASON.ParseOptions` = {
  bigIntMode: `ArkTSUtils.ASON.BigIntMode.PARSE_AS_BIGINT`,
  parseReturnType: `ArkTSUtils.ASON.ParseReturnType.OBJECT`,
}
let numberText = '{"largeNumber":112233445566778899}';
let numberObj = `ArkTSUtils.ASON.parse(numberText,undefined,options)` as ISendable;

console.info((numberObj as object)?.["largeNumber"]);
// 期望输出: 112233445566778899
