this.$refs.a02VOList.commitProxy('reload') not read properties of undefined (reading 'commitProxy')

这个错误通常是因为`this.$refs.a02VOList`为`undefined`,而你尝试访问它的属性`commitProxy`导致的。这种情况下,你可以先确保`this.$refs.a02VOList`被正确地引用或初始化。检查一下你的代码,确保在使用`this.$refs.a02VOList`之前已经正确地定义和赋值。另外,也可以考虑查看是否在组件的生命周期中正确地调用了相关的方法或钩子函数。如果问题仍然存在,请提供更多的代码和上下文,以便更好地帮助你解决问题。

this.$refs. undefined
this.$refs是Vue.js框架中的一个特殊属性,用于访问组件或DOM元素的引用。通过在模板中使用ref属性,可以给组件或DOM元素添加一个唯一的标识符,然后可以使用this.$refs来访问这个标识符对应的组件或DOM元素。
this.$refs是一个对象,它的属性名对应着ref属性的值,属性值则是对应的组件实例或DOM元素。例如,如果在模板中有一个ref="myComponent"的组件,那么可以使用this.$refs.myComponent来访问这个组件的实例。
而this.$refs.undefined则表示没有找到对应的ref属性值为"undefined"的组件或DOM元素。这可能是因为没有在模板中定义相应的ref属性,或者ref属性值拼写错误导致无法找到对应的组件或DOM元素。
this.$refs.formValidate.resetFields() Cannot read properties of undefined (reading 'indexOf')
The error message "Cannot read properties of undefined (reading 'indexOf')" usually occurs when you are trying to access a property or invoke a method on an undefined value. In this case, it seems like you are trying to reset fields using `this.$refs.formValidate.resetFields()`, but `formValidate` is undefined.
To fix this issue, make sure that you have defined `formValidate` and it is properly assigned to the form reference using `ref` attribute in your template. Here's an example of how you can define and use `formValidate`:
In your template:
```html
<template>
<el-form ref="formValidate" :model="formData" :rules="formRules">
<!-- form fields -->
</el-form>
</template>
```
In your component's script:
```javascript
<script>
export default {
data() {
return {
formData: {}, // initialize form data object
formRules: {}, // define form validation rules
}
},
methods: {
resetForm() {
// make sure that this.$refs.formValidate is defined
if (this.$refs.formValidate) {
this.$refs.formValidate.resetFields();
}
}
},
}
</script>
```
By following this pattern, you should be able to resolve the error and reset the form fields successfully.
