this.$refs.form.reset是Vue.js框架中的一种方法,用于重置表单字段的值。在上述引用中,三种解决方式都是将表单字段的值手动置空,以实现重置的效果。具体的代码如下:
```
this.$refs.form.resetFields();
this.form.name = '';
this.form.description = '';
this.form.id = '';
```
这段代码将重置表单字段的值,其中this.$refs.form.resetFields()用于重置表单验证状态,而this.form.name、this.form.description和this.form.id则分别用于将对应的表单字段置为空字符串。

报错了,this.$refs.form.reset is not a function
如果你使用的是`this.$refs.form.reset()`方法重置表单,但是却出现了`reset is not a function`的错误,这通常是因为表单元素的引用名称和`$refs`对象的名称不一致导致的。你可以尝试以下两种方法解决这个问题:
1. 确保在表单元素上设置了`ref`属性,并使用正确的名称。
```
<form ref="myForm">
...
</form>
```
在这个例子中,我们将表单元素的引用名称设置为“myForm”,因此我们可以在Vue实例中使用`this.$refs.myForm`来访问该元素。
2. 通过`$nextTick()`方法确保表单元素已经被渲染。
```
resetForm() {
this.$nextTick(() => {
this.$refs.form.reset();
});
}
```
在这个例子中,我们使用`$nextTick()`方法确保在调用`reset()`方法之前表单元素已经被渲染。这可以解决在表单元素还没有被渲染的情况下调用`reset()`方法导致的错误。
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.
