element 结合vue 在表单验证时有值却提示错误的解决办法

<el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">

<el-form-item label="活动名称" prop="name"> <el-input v-model="ruleForm.name"></el-input> </el-form-item>

rules: {
name: [
{ required: true, message: '请输入活动名称', trigger: 'blur' },
{ min: 3, max: 5, message: '长度在 3 到 5 个字符', trigger: 'blur' }
],
resource: [
{ required: true, message: '请选择活动资源', trigger: 'change' }
],
}

submitForm(formName) {
this.$refs[formName].validate((valid) => {
if (valid) {

} else {
console.log('error submit!!');
return false;
}
});
},
