微信小程序實現簡易封裝彈窗
本文實例為大傢分享瞭微信小程序實現簡易封裝彈窗的具體代碼,供大傢參考,具體內容如下
1.建立組件文件夾
2.編寫組件內容
<!--index.wxml--> <view class="container"> <text>demo 01 heihzi</text> <view bindtap="onDialog">點擊 打開彈窗</view> </view> <dialog id="dialog" title="查看詳情"> <scroll-view class="p-b min-ht" scroll-y style="height: 700rpx;"> <view class="dia-warp"> <text>詳情信息</text> <view wx:for="{{20}}" wx:key="index">{{item}}</view> </view> </scroll-view> </dialog>
// components/dialong/index.js Component({ /** * 組件的屬性列表 */ properties: { title: { type: String } }, /** * 組件的初始數據 */ data: { show: false, zIndex: 0, ablClickMask: true, hasClsBtn: false, title: '' }, /** * 組件的方法列表 */ methods: { open(params, cb, fb) { params = params || {} this.setData({ show: true, zIndex: params.zIndex || 0 }) this.data._cb = cb this.data._fb = fb }, close() { this.setData({ show: false }) }, onMaskHide() { if (this.data.ablClickMask) { this.close() this.triggerEvent('maskEvt') } } } })
樣式一定要加 不然組件彈窗出不來
/* components/dialong/index.wxss */ /* 彈窗 */ .pop { width: 80%; background: #fff; border-radius: 12rpx; height: auto; max-height: 70vh; margin: auto; position: absolute; position: fixed; left: 0; right: 0; top: 20vh; opacity: 0; overflow: hidden; transform: scale(0.5, 0.5); -webkit-transform: scale(0.5, 0.5); transition: all 0.2s ease; -webkit-transition: all 0.2s ease; } .pop-enter { opacity: 1; transform: scale(1, 1); -webkit-transform: scale(1, 1); z-index: 1000; } .mask { width: 100vw; height: 100vh; box-sizing: border-box; background: rgba(0, 0, 0, 0.6); position: fixed; top: 0; bottom: 0; left: 0; right: 0; z-index: 700; } .title { text-align: center; padding: 20rpx 0; border-bottom: 1rpx solid #CCC; }
組件的引入 index .json
"usingComponents" : { "dialog" : "/components/dialong/index" },
3.頁面中使用
<!--index.wxml--> <view class="container"> <text>demo 01 heihzi</text> <view bindtap="onDialog">點擊 打開彈窗</view> </view> <dialog id="dialog" title="查看詳情"> <scroll-view class="p-b min-ht" scroll-y style="height: 700rpx;"> <view class="dia-warp"> <text>詳情信息</text> <view wx:for="{{20}}" wx:key="index">{{item}}</view> </view> </scroll-view> </dialog>
//index.js //獲取應用實例 const app = getApp() Page({ data: { }, onLoad: function () { }, onDialog () { console.log('打開我啊') this.dialog.open() }, onReady () { this.dialog = this.selectComponent("#dialog") } })
