可自定义设置以下属性:
-
单选元素数据(options),必传,类型:Array<{label: string, value: any, disabled?: boolean}>
-
是否禁用所有子单选器(disabled),默认false
-
是否垂直排列(vertical),默认false
-
当前选中的值(v-model:value),默认null
-
多个单选框之间的间距(gap),单位px,默认8px
效果如下图:
①创建单选框组件Radio.vue
<script setup lang="ts">
import { computed } from 'vue'
interface Option {
label: string,
value: any,
disabled?: boolean // 是否禁用单个单选器
}
interface Props {
options: Array<Option>, // 单选元素数据
disabled?: boolean, // 是否禁用所有子单选器
vertical?: boolean, // 是否垂直排列
value?: any, // 当前选中的值(v-model)
gap?: number // 多个单选框之间的间距,单位px
}
const props = withDefaults(defineProps<Props>(), {
options: () => [],
disabled: false,
vertical: false,
value: null,
gap: 8
})
const sum = computed(() => {
return props.options.length
})
const styleObject = computed(() => {
if (props.vertical) {
return {
marginBottom: props.gap + 'px'
}
} else {
return {
marginRight: props.gap + 'px'
}
}
})
const emits = defineEmits(['update:value', 'change'])
function onClick (value: any) {
if (value !== props.value) {
emits('update:value', value)
emits('change', value)
}
}
</script>
<template>
<div class="m-radio" :class="{'vertical': vertical}">
<div
class="m-radio-wrap"
:class="{'disabled': disabled || option.disabled}"
:style="sum !== index + 1 ? styleObject: ''"
@click="(disabled || option.disabled) ? (e: Event) => e.preventDefault() : onClick(option.value)" v-for="(option, index) in options" :key="index">
<span class="u-radio" :class="{'u-radio-checked': value === option.value }"></span>
<span class="u-label">{
{ option.label }}</span>
</div>
</div>
</template>
<style lang="less" scoped>
.m-radio {
display: inline-flex;
height: 24px;
.m-radio-wrap {

}
}
.u-radio {
position: relative;
display: inline-block;

height: 14px;
background: #fff;
border: 1px solid #d9d9d9;

}
}
.u-radio-checked {

}
}
.u-label {
padding: 0 8px;
font-size: 16px;

}
}
.disabled {
color: #00000040;
cursor: not-allowed;
&:hover {
.u-radio {
border-color: #d9d9d9;
}
}
.u-radio {
border-color: #d9d9d9;
background-color: #f5f5f5;
&:after {
background-color: rgba(0, 0, 0, 0.2);
}
}
}
}
.vertical {
display: inline-block;
}
</style>
②在要使用的页面引入:
<script setup lang="ts">
import { Radio } from './Radio.vue'
import { ref, watch } from 'vue'
const options = ref([
{
label: '北京市',
value: 1
},
{
label: '上海市上海市上海市上海市',
value: 2,
disabled: true
},
{
label: '郑州市',
value: 3
},
{
label: '纽约市纽约市纽约市纽约市',
value: 4
},
{
label: '旧金山',
value: 5
},
{
label: '悉尼市',
value: 6
},
{
label: '伦敦市',
value: 7
},
{
label: '巴黎市',
value: 8
}
])
const value = ref(1)
watch(value, (to) => {
console.log('p to:', to)
})
function onChange (value: any) {
console.log('change:', value)
}
</script>
<template>
<div>
<h2 class="mb10">Radio 单选框基本使用</h2>
<p class="u-intro">用于在多个备选项中选中单个状态</p>
<Radio
:options="options"
:gap="16"
:vertical="false"
@change="onChange"
v-model:value="value" />
</div>
</template>
<style lang="less" scoped>
</style>
