首先准备好按钮内容:const a = ['one','two','three']
将按钮循环展示出来,并设置一些样式,将按钮背景透明:
<button v-for="(item,index) in a" :key="index">{{ item }}</button>
button {
width: 100px;
height: 40px;
border-radius: 20px;
border: 1px solid red;
background-color: transparent;
}
在外面包裹一个div,设置背景颜色,border-radius与按钮一致(按钮边框和背景透明,这样背景是什么颜色/边框,按钮就会是什么颜色/边框):
<div class="container">
<button v-for="(item,index) in a" :key="index">{{ item }}</button>
</div>
.container {
margin:40px;
border: 1px solid transparent;
display: inline-block;
padding: 0;
border-radius: 20px;
height: 40px;
background-color: #ECEFEE;
}
button {
width: 100px;
height: 40px;
border-radius: 20px;
border: 1px solid transparent;
background-color: transparent;
}
最后加上选中效果,因为是单选所以必须保证每次只能选中一个,动态绑定class:
<div class="container">
<button v-for="(item,index) in a" :key="index" :class="radio==item?'yes':''" @click="handleClick(item)">{{ item }}</button>
</div>
const radio = ref('one') // 默认选中
const handleClick = (value) =>{
radio.value = value
}
.container{
margin:40px;
border: 1px solid transparent;
display: inline-block;
padding: 0;
border-radius: 20px;
height: 40px;
background-color: #ECEFEE;
}
button{
width: 100px;
height: 40px;
border-radius: 20px;
border: 1px solid transparent;
background-color: transparent;
}
.yes {
background: red;
color: white;
}
