需求：校验el-input输入为0-100的数字 

 <el-form :label-position="'top'" label-width="80px" ref="ogdiskForm" :model="originalDiskForm" :rules="rules" class="form"><el-form-item label="目标比例：(磁盘达到该比例后，将出现阈值提示)" v-if="originalDiskForm.type !== 'object'" prop="useAblePercent"><!-- @input="numValid" --><el-input v-model="originalDiskForm.useAblePercent" style="width: 270px"><template slot="append">%</template></el-input></el-form-item>
</el-form>data(){var checkPct = (rule, value, callback) => {if (!Number(value)) {if(value == 0){callback();}else{callback(new Error('请输入数字'));}} else {if (value < 0) {callback(new Error('目标比例不能小于0'));} else if(value > 100){callback(new Error('目标比例不能大于100'));} else{callback();}}}return {// 原盘符数据表单originalDiskForm: {useAblePercent: '',},rules:{useAblePercent:[{validator: checkPct, trigger: 'blur'}],}}}
