前端针对需要递增的固定数据

这里递增的是1到12

data(){return{cycleOptions:Array.from({ length: 12 }, (v, k) => ({value: k + 1,label: String(k + 1)})),}
}

 <el-select v-model="ruleForm.monthLength" placeholder="请选择周期数量"><el-optionv-for="item in cycleOptions":key="item.value":label="item.label":value="item.value"></el-option></el-select>
