ElementUI浅尝辄止34：Radio 单选框

在一组备选项中进行单选

1.如何使用？

由于选项默认可见，不宜过多，若选项过多，建议使用 Select 选择器。

//要使用 Radio 组件，只需要设置v-model绑定变量，选中意味着变量的值为相应 Radio label属性的值，label可以是String、Number或Boolean。<template><el-radio v-model="radio" label="1">备选项</el-radio><el-radio v-model="radio" label="2">备选项</el-radio>
</template><script>export default {data () {return {radio: '1'};}}
</script

2.禁用状态

单选框不可用的状态。

//只要在el-radio元素中设置disabled属性即可，它接受一个Boolean，true为禁用。<template><el-radio disabled v-model="radio" label="禁用">备选项</el-radio><el-radio disabled v-model="radio" label="选中且禁用">备选项</el-radio>
</template><script>export default {data () {return {radio: '选中且禁用'};}}
</script>

3.单选框组

适用于在多个互斥的选项中选择的场景

/*结合el-radio-group元素和子元素el-radio可以实现单选组，在el-radio-group中绑定v-model，在el-radio中设置好label即可，无需再给每一个el-radio绑定变量，另外，还提供了change事件来响应变化，它会传入一个参数value。*/<template><el-radio-group v-model="radio"><el-radio :label="3">备选项</el-radio><el-radio :label="6">备选项</el-radio><el-radio :label="9">备选项</el-radio></el-radio-group>
</template><script>export default {data () {return {radio: 3};}}
</script>

4.按钮样式

按钮样式的单选组合。

<template><div><el-radio-group v-model="radio1"><el-radio-button label="上海"></el-radio-button><el-radio-button label="北京"></el-radio-button><el-radio-button label="广州"></el-radio-button><el-radio-button label="深圳"></el-radio-button></el-radio-group></div><div style="margin-top: 20px"><el-radio-group v-model="radio2" size="medium"><el-radio-button label="上海" ></el-radio-button><el-radio-button label="北京"></el-radio-button><el-radio-button label="广州"></el-radio-button><el-radio-button label="深圳"></el-radio-button></el-radio-group></div><div style="margin-top: 20px"><el-radio-group v-model="radio3" size="small"><el-radio-button label="上海"></el-radio-button><el-radio-button label="北京" disabled ></el-radio-button><el-radio-button label="广州"></el-radio-button><el-radio-button label="深圳"></el-radio-button></el-radio-group></div><div style="margin-top: 20px"><el-radio-group v-model="radio4" disabled size="mini"><el-radio-button label="上海"></el-radio-button><el-radio-button label="北京"></el-radio-button><el-radio-button label="广州"></el-radio-button><el-radio-button label="深圳"></el-radio-button></el-radio-group></div>
</template><script>export default {data () {return {radio1: '上海',radio2: '上海',radio3: '上海',radio4: '上海'};}}
</script>

5.带有边框

设置border属性可以渲染为带有边框的单选框。<template><div><el-radio v-model="radio1" label="1" border>备选项1</el-radio><el-radio v-model="radio1" label="2" border>备选项2</el-radio></div><div style="margin-top: 20px"><el-radio v-model="radio2" label="1" border size="medium">备选项1</el-radio><el-radio v-model="radio2" label="2" border size="medium">备选项2</el-radio></div><div style="margin-top: 20px"><el-radio-group v-model="radio3" size="small"><el-radio label="1" border>备选项1</el-radio><el-radio label="2" border disabled>备选项2</el-radio></el-radio-group></div><div style="margin-top: 20px"><el-radio-group v-model="radio4" size="mini" disabled><el-radio label="1" border>备选项1</el-radio><el-radio label="2" border>备选项2</el-radio></el-radio-group></div>
</template><script>export default {data () {return {radio1: '1',radio2: '1',radio3: '1',radio4: '1'};}}
</script>
