验证输入字符串必须为数字

html:

                <FormItem label="兑换积分：" prop="exchangeIntegral">
                    <Input v-model="formSpecAdd.exchangeIntegral" placeholder="请输入兑换积分" style="width: 250px"></Input>
                </FormItem>
 
                <FormItem label="库存数量：" prop="stockNum">
                    <Input v-model="formSpecAdd.stockNum" placeholder="请输入库存数量" style="width: 250px"></Input>
                </FormItem>
 
                <FormItem label="商品价值：" prop="productMoney">
                    <Input v-model="formSpecAdd.productMoney" placeholder="请输入商品价值" style="width: 250px"></Input>
                </FormItem>

js:

                    exchangeIntegral: [
                        {required: true, message: '请输入兑换积分', trigger: 'blur'},
                        {type: 'string', pattern: /^\d+$/, message: '请输入数字', trigger: 'blur'}
                    ],
 
                    stockNum: [
                        {required: true, message: '请输入库存数量', trigger: 'blur'},
                        {type: 'string', pattern: /^\d+$/, message: '请输入数字', trigger: 'blur'}
                    ],
 
                    productMoney: [
                        {required: true, message: '请输入商品价值', trigger: 'blur'},
                        {type: 'string', pattern: /^\d+$/, message: '请输入数字', trigger: 'blur'}
                    ],

或者： 直接将输入框定义为 number类型

                <FormItem label="兑换积分：" prop="exchangeIntegral">
                    <Input v-model="formSpecAdd.exchangeIntegral" number placeholder="请输入兑换积分" style="width: 250px"></Input>
                </FormItem>

js:验证

                    exchangeIntegral: [
                        {required: true, type: 'number', message: '请输入兑换积分', trigger: 'blur'},
                        {type: 'number', message: '请输入数字', trigger: 'blur'}
                    ],
