微信小程序 Toast自定义实例详解
实现类似于Android的Toast提示 

index.js:
var timer; var inputinfo = ""; var app = getApp() Page({data: { animationData:"", showModalStatus:false},onLoad: function () { },showModal: function () { // 显示遮罩层 var animation = wx.createAnimation({duration: 200,timingFunction: "linear",delay: 0 }) this.animation = animation animation.translateY(200).step() this.setData({animationData: animation.export(),showModalStatus: true }) setTimeout(function () {animation.translateY(0).step()this.setData({ animationData: animation.export()}) }.bind(this), 200) console.log("准备执行");timer = setTimeout(function () { if(this.data.showModalStatus){this.hideModal();console.log("是否执行");} }.bind(this), 3000)},clickbtn:function(){ if(this.data.showModalStatus){this.hideModal(); }else{this.showModal(); }},hideModal: function () { if(timer != null){clearTimeout(timer);timer = null; } // 隐藏遮罩层 var animation = wx.createAnimation({duration: 200,timingFunction: "linear",delay: 0 }) this.animation = animation animation.translateY(200).step() this.setData({animationData: animation.export(), }) setTimeout(function () {animation.translateY(0).step()this.setData({ animationData: animation.export(), showModalStatus: false}) }.bind(this), 200)}, }) 

index.wxml:

<button type="default" bindtap="clickbtn">点击 </button> <view class="commodity_screen" bindtap="hideModal" wx:if="{{showModalStatus}}"></view> <view animation="{{animationData}}" class="commodity_attr_box" wx:if="{{showModalStatus}}"> <!--对话框标题--><view class="title-view"> <view class="toast-view">要显示的内容 </view> </view> </view>
