鸿蒙 next -arkts- 实现防抖节流功能

export class ClickUtil {  private constructor() {  }
  private static throttleTimeoutID: number; //节流timeoutID  private static flag: boolean = false; //节流flag,true=已经进入执行状态了  private static debounceCacheID: number; //防抖timeoutID
  static throttle(func: () => void, wait: number = 1000, immediate: boolean = true) {    if (immediate) {      if (!ClickUtil.flag) {        ClickUtil.flag = true;        typeof func === 'function' && func();        ClickUtil.throttleTimeoutID = setTimeout(() => {          ClickUtil.flag = false;          clearTimeout(ClickUtil.throttleTimeoutID);        }, wait);      }    } else {      if (!ClickUtil.flag) {        ClickUtil.flag = true;        ClickUtil.throttleTimeoutID = setTimeout(() => {          ClickUtil.flag = false;          typeof func === 'function' && func();          clearTimeout(ClickUtil.throttleTimeoutID);        }, wait);      }    }  }


  static debounce(func: () => void, wait: number = 1000) {    if (ClickUtil.debounceCacheID) {      clearTimeout(ClickUtil.debounceCacheID);    }
    let timeoutID = setTimeout(() => {      typeof func === 'function' && func();      clearTimeout(timeoutID);    }, wait);
    ClickUtil.debounceCacheID = timeoutID;
