elementui Cannot read properties of undefined (reading 'resetFields')

The error message "Cannot read properties of undefined (reading 'resetFields')" typically occurs when you try to access the 'resetFields' property of an undefined object in Element UI. This error usually happens when you haven't properly initialized or imported the necessary components.

To resolve this issue, please make sure you have done the following:

1. Import the required Element UI components correctly in your code:

   import { Form, Button } from 'element-ui';

2. Register the components in your Vue application:

   Vue.use(Form);
   Vue.use(Button);

3. Ensure that you have defined the 'form' object in your component's data:

   data() {
     return {
       form: {
         // Your form fields
       }
     }
   }

4. Make sure you have properly set up the form structure in your template:

   <el-form :model="form" ref="myForm">
     <!-- Your form fields -->
   </el-form>

5. Finally, you can call the 'resetFields' method on the form reference to clear the form:

   this.$refs.myForm.resetFields();

By following these steps, you should be able to resolve the "Cannot read properties of undefined (reading 'resetFields')" error in Element UI.
