el-form表单校验输入框值为0时提示校验不通过

配置validator自定义校验方法

这里举例在结构代码里加入校验规则

<el-form-item:prop="num":rules="[{required: true,message: '请输入数量',trigger: 'change',},{validator,trigger: 'blur'}]"
><el-input-number v-model="num" />
</el-form-item>methods: {// 规则定义validator(rule, value, callback) {if (value === 0) {callback(new Error('数量不能为 0'));} else {callback();}}}
