uniapp封装组件，选中后右上角显示对号√样式（通过css实现）

效果：

一、组件封装

1、在项目根目录下创建components文件夹，自定义组件名称，我定义的是xc-button

2、封装组件代码

<template><view class="handle-btn"><view :class="handleIdCode == '1' ? 'select' : 'unSelect'" @click="agreeBtn">{{agreeLabel}}</view><view :class="handleIdCode == '0' ? 'select' : 'unSelect'" @click="unAgreeBtn">{{unAgreeLabel}}</view></view>
</template><script>export default {name:"xc-button",props:{handleId:{type: String,default:"",},//lable值agreeLabel: {type: String,default:"",},//lable值unAgreeLabel: {type: String,default:"",}},data() {return {handleIdCode:''};},methods:{agreeBtn(){this.handleIdCode = '1',this.$emit('agreeBtn')},unAgreeBtn(){this.handleIdCode = '0',this.$emit('unAgreeBtn')},},onLoad() {this.handleIdCode = this.handleId}}
</script><style lang="scss">
// 按钮样式	
.handle-btn{display: flex;
}
.select {position: relative;box-sizing: border-box;display: flex;flex-direction: column;justify-content: center;align-items: center;padding: 16rpx 32rpx;width: 120rpx;height: 56rpx;border-radius: 2px;margin: 0 10rpx;background-color: #E8F3FF;color: #5999fc;
}
.select:before {content: '';position: absolute;right: 0;top: 0;border: 24rpx solid #5999fc;border-top-color: transparent;border-left-color: transparent;transform: rotate(-90deg);}.select:after {content: '';width: 2px;height: 5px;position: absolute;right: 3px;top: 5px;border: 1px solid #fff;border-top-color: transparent;border-left-color: transparent;transform: rotate(45deg);}
.unSelect{box-sizing: border-box;display: flex;flex-direction: column;justify-content: center;align-items: center;padding: 16rpx 32rpx;width: 120rpx;height: 56rpx;background: #F8F8F8;border: 0.5px solid #F8F8F8;border-radius: 2px;margin: 0 10rpx;}
</style>

二、在页面中使用组件

<template><view><xc-button agreeLabel="是"  unAgreeLabel="否" handleId="1" @agreeBtn="agreeBtn" @unAgreeBtn="unAgreeBtn"></xc-button></view>
</template><script>export default {data() {return {};},methods: {agreeBtn() {console.log('是被触发了')},unAgreeBtn() {console.log('否被触发了')},}}
</script><style lang="scss"></style>
