这篇文章主要为大家展示了“微信小程序自定义波浪组件怎么用”,内容简而易懂,条理清晰,希望能够帮助大家解决疑惑,下面让小编带领大家一起研究并学习一下“微信小程序自定义波浪组件怎么用”这篇文章吧。
先看看效果图:里面的文本是组件内部定义的。
这是用两个svg的图片用css关键帧动画做的效果(这里谢谢子弹短信里前端群的小伙伴提供的web版的css动画文件)
在小程序中使用,注意一个问题:就是svg不可以直接使用,需要转为base64(这个大家应该有收藏吧),这里我已经转换好了,在下面的wxss中。
这里顺便用一下自定义组件:
首先定义组件 wave
wave.wxml:这里我默认是用得显示个人信息。其中isShowInfo来控制是否显示
<!--utils/wave/waves.wxml--> <view class="zr"> <view class='user_box' hidden="{{isShowInfo}}"> <view class='userInfo'> <open-data type="userAvatarUrl"></open-data> </view> <view class='userInfo_name'> <open-data type="userNickName"></open-data>,欢迎您 </view> </view> <view class="water"> <view class="water-c"> <view class="water-1"> </view> <view class="water-2"> </view> </view> </view> </view>
wave.js:这里组件定义一个私有方法 __hideInfo(),用来隐藏内部组件,灵活运用很方便。
// utils/wave/waves.js Component({ /** * 组件的属性列表 */ properties: { }, /** * 组件的初始数据 */ data: { isShowInfo:false }, /** * 组件的方法列表 */ methods: { __hideInfo:function(){ this.setData({ isShowInfo:true }) } }, })
wave.json:第一个是设置为自定义组件,第二个可选是使用其他的自定义组件,比如引用组件,一会就会用得
{ "component": true, "usingComponents": {} }
wave.wxss:zr的背景直接改为自己需要的,或者用属性传递。
/*组件背景颜色*/ .zr { background: #0396FF; width: 100%; height:100px; position: relative; } .water { position: absolute; left: 0; bottom: -10px; height: 30px; width: 100%; z-index: 1 } .water-c { position: relative } .water-1 { background: url("data:image/svg+xml;base64,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") repeat-x; background-size: 600px; -webkit-animation: wave-animation-1 3.5s infinite linear; animation: wave-animation-1 3.5s infinite linear } .water-2 { top: 5px; background: url("data:image/svg+xml;base64,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") repeat-x; background-size: 600px; -webkit-animation: wave-animation-2 6s infinite linear; animation: wave-animation-2 6s infinite linear } .water-1, .water-2 { position: absolute; width: 100%; height: 60px } .back-white { background: #fff } @keyframes wave-animation-1 { 0% { background-position: 0 top } 100% { background-position: 600px top } } @keyframes wave-animation-2 { 0% { background-position: 0 top } 100% { background-position: 600px top } } .user_box { display: flex; z-index: 10000!important; } .userInfo_name { flex: 1; vertical-align: middle; width: 100%; margin-left: 5%; margin-top: 5%; } .userInfo { flex: 1; width: 100%; border-radius: 50%; overflow: hidden; max-height: 50px; max-width: 50px; margin-left: 5%; margin-top: 5%; border: 2px solid #fff; }
组件定义完,下面是引用这个组件:
index.json:这里用到了userxxx使用我们定义的组件,引用名为wave,这也是一会使用的节点名,和view一样直接用
{ //使用组件,引用名(直接当做节点使用),路径 "usingComponents": { "wave": "../com/wave/waves" } }
index.wxml
index.js:通过wave设置的id获取组件对象,调用私有方法。去除内部信息。
onLoad: function (options) { this.wave = this.selectComponent("#wave"); this.wave.__hideInfo() },
再来一个静态图:
好了。
