使用了一段時(shí)間的ts，感覺(jué)使用js有點(diǎn)不順手；所以就找到了,來(lái)開(kāi)發(fā)微信小程序;

數(shù)據(jù)同步：

在下新建event.ts；（在src下新建一個(gè)的文件夾小程序js同步執(zhí)行，用于存放公共的方法）；

class Event {
	/**事件列表*/
	private eventList = {};
    /**
     * 發(fā)送事件
     * @type 事件類型
     * @args 攜帶數(shù)據(jù)
     */
	public sendEvent(type: string, ...args: any[]) {
		let arr: Array = this.eventList[type];
		if (arr != null) {
			let len = arr.length;
			let listen: Function;
			let thisObject: any;
			for (let i = 0; i < len; i++) {
				let msg = arr[i];
				listen = msg[0];
				thisObject = msg[1];
				listen.apply(thisObject, args);
			}
		}
	}
    /**
     * 監(jiān)聽(tīng)事件
     * @type 事件類型
     * @listener 回調(diào)函數(shù)
     * @thisObject 回調(diào)執(zhí)行對(duì)象
     */
	public addEvent(type: string, listener: Function, thisObject: any) {
		let arr: Array = this.eventList[type];
		if (arr == null) {
			arr = [];
			this.eventList[type] = arr;
		} else {
			let len = arr.length;
			for (let i = 0; i < len; i++) {
				if (arr[i][0] == listener && arr[i][1] == thisObject) {
					return;
				}
			}
		arr.push([listener, thisObject]);
	}
    /**
     * 移除事件
     * @type 事件類型
     * @listener 回調(diào)函數(shù)
     * @thisObject 回調(diào)執(zhí)行對(duì)象
     */
	public removeEvent(type: string, listener: any, thisObject: any) {
		let arr: Array = this.eventList[type];
		if (arr != null) {
			let len = arr.length;
			for (let i = len - 1; i >= 0; i--) {
				if (arr[i][0] == listener && arr[i][1] == thisObject) {
					arr.splice(i, 1);
				}
			}
		if (arr && arr.length == 0) {
			this.eventList[type] = null;
			delete this.eventList[type];
		}
	}
}
export const $Event = new Event();

在你需要發(fā)布的頁(yè)面ts中引入event.ts;

import { $Event } from 'common/event';

比如說(shuō)在請(qǐng)求成功以后去發(fā)布事件；

$Event.sendEvent('like', { id: this.data.articalId });//這邊傳id

監(jiān)聽(tīng)事件：

在你需要的頁(yè)面ts中 引入event.ts

import { $Event } from 'common/event';
async onLoad(options:any){
? ? ? //監(jiān)聽(tīng)事件
? ? ? $Event.addEvent("like", (e: any) => {
? ? ? ? ? ? ?//取id的話就是e.id;
? ? ? ? ? ? ?this.setRecommendLike(e); //接收到參數(shù)進(jìn)行的操作；
? ? ? ?}, this);
}

移除監(jiān)聽(tīng)事件：

onUnload() {
	$Event.removeEvent("like", (e: any) => { console.log(e, '移除監(jiān)聽(tīng)事件') }, this);
	$Event.removeEvent("comment", (e: any) => { console.log(e, '移除監(jiān)聽(tīng)評(píng)論數(shù)量事件') }, this);
	$Event.removeEvent("forward", (e: any) => { console.log(e, '移除監(jiān)聽(tīng)轉(zhuǎn)發(fā)數(shù)量事件') }, this);
	$Event.removeEvent("fansCount", (e: any) => { console.log(e, '移除關(guān)注事件') }, this);
}

如有錯(cuò)誤小程序js同步執(zhí)行，請(qǐng)指正！ 非常感謝！
