本文實(shí)例講述了微信小程序自定義toast組件的方法。分享給大家供大家參考,具體如下:
怎么創(chuàng)建就不說了,前面一篇有
微信小程序自定義prompt組件
直接上代碼
wxml
<!-- components/toast/toast.wxml --> <view class="toast-box {{isShow? 'show':''}}" animation="{{animationData}}"> <view class="toast-content" > <view class="toast-img"> <block wx:if="{{type==='success'}}"> <image class="toast-icon" src="xxx" /> </block> <block wx:if="{{type==='fail'}}"> <image class="toast-icon" src="xxx" /> </block> </view> <view class="toast-title">{{title}}</view> </view> </view>
js
// components/toast/toast.js Component({ properties: { }, data: { type: 'fail', title: '你還沒有勾選呢!', isShow: false, animationData: '' }, methods: { showToast: function (data) { const self = this; if (this._showTimer) { clearTimeout(this._showTimer) } if (this._animationTimer) { clearTimeout(this._animationTimer) } // display需要先設(shè)置為block之后,才能執(zhí)行動(dòng)畫 this.setData({ title: data.title, type: data.type, isShow: true, }); this._animationTimer = setTimeout(() => { const animation = wx.createAnimation({ duration: 500, timingFunction: 'ease', delay: 0 }) animation.opacity(1).step(); self.setData({ animationData: animation.export(), }) }, 50) this._showTimer = setTimeout(function () { self.hideToast(); if (data.compelete && (typeof data.compelete === 'function')) { data.compelete() } }, 1200 || (50 + data.duration)) }, hideToast: function () { if (this._hideTimer) { clearTimeout(this._hideTimer) } let animation = wx.createAnimation({ duration: 200, timingFunction: 'ease', delay: 0 }) animation.opacity(0).step(); this.setData({ animationData: animation.export(), }) this._hideTimer = setTimeout(() => { this.setData({ isShow: false, }) }, 250) } } })
json
{ "component": true, "usingComponents": {} }
wxss
/* components/toast/toast.wxss */ .toast-box { position: absolute; left: 0; top: 0; width: 100%; height: 100%; z-index: 11; display: none; opacity: 0; } .show{ display: block; } .toast-content { position: absolute; left: 50%; top: 35%; width: 350rpx; /*height: 250rpx;*/ border-radius: 10rpx; box-sizing: bordre-box; transform: translate(-50%, -50%); background: rgba(0, 0, 0, .7); } .toast-img{ width: 100%; height: 120rpx; padding-top: 15rpx; box-sizing: bordre-box; text-align: center; } .toast-icon{ width: 100rpx; height: 100rpx; } .toast-title { width: 100%; padding:10rpx; line-height: 65rpx; color: white; text-align: center; font-size: 40rpx; box-sizing: border-box; }
使用
例如,在index.html中使用
在json中添加useComponents屬性
"usingComponents": { "vas-prompt": "./components/toast/toast" }
wxml
<vas-toast id='toast'></vas-toast> <button bindtap="showToast">點(diǎn)擊彈出toast</button>
js
//在onReady生命周期函數(shù)中,先獲取prompt實(shí)例 onReady:function(){ this.prompt = this.selectComponent("#toast"); }, showToast:function(){ this.toast.showToast({ type: 'success', title: '測(cè)試彈出消息', duration: 1000, compelete: function () { console.log('toast框隱藏之后,會(huì)調(diào)用該函數(shù)') //例如:跳轉(zhuǎn)頁(yè)面wx.navigateTo({ url: 'xxx' }); } }) },
效果
希望本文所述對(duì)大家微信小程序開發(fā)有所幫助。
