Clearcache(editData) { this.$refs[editData].validate(valid => { if (valid) { CacheClear(this.form) .then(res => { this.getdata() this.getmenu() }) .catch(err => { this.$message.error('数据保存失败,请稍后再试!') }) } else { return false } }) },解释这个方法

这是一个Vue组件中的一个方法,用于清除缓存。具体解释如下:
- `Clearcache(editData)` 是一个方法名,用于清除缓存,其中 `editData` 是一个参数,表示需要清除的数据。
- `this.$refs[editData].validate` 是Vue组件中的一个方法,用于验证表单数据。如果表单数据通过验证,就会执行接下来的代码。
- `CacheClear(this.form)` 是一个异步方法,用于清除缓存,其中 `this.form` 是一个对象,表示需要清除的数据。
- `.then(res => {})` 表示异步方法执行成功后的回调函数,其中 `res` 是返回的结果。
- `this.getdata()` 和 `this.getmenu()` 是两个方法,用于重新获取数据。
- `.catch(err => {})` 表示异步方法执行失败后的回调函数,其中 `err` 是错误信息。如果清除缓存失败,就会在页面上弹出一个错误提示框,告诉用户数据保存失败,请稍后再试。

This code is a method call on a Vue.js component instance. It is calling the `validate` method on the `login` element, which is a child component of the current component. The `validate` method takes a callback function as its argument, which will be called with a boolean value indicating whether the validation was successful or not. If the validation is successful (`valid` is `true`), then some action can be taken, such as submitting the form or navigating to a new page.
