开发自定义画面经常遇到的场景就是增删改查，关于数据更新用到的几个方法进行一下总结，常用到的有以下几种。

·【lightning-record-edit-form】+【lightning-input-field】

※数据初期化和数据更新用标签自带功能，不用特殊处理，相对简单，但也有一些限制。

·【lightning-record-form】+【lightning-input】+【getRecord】+【updateRecord】

※方法1如果有限制，就可以用这个方法，比如Event/Task不支持方法1

·【lightning-record-form】+【lightning-input】+【getRecord】+Apex代码（数据更新）

※方法2如果有限制，就可以用这个方法，比如要更新的项目，当前用户没有权限。

·【lightning-record-form】+【lightning-input】+Apex代码（数据取得）+Apex代码（数据更新）

※方法2如果有限制，就可以用这个方法，比如画面需要表示的项目是关联表的情况下，用Apex代码一次取得所有项目。

更新后状态↓↓↓↓↓↓

虽然更新成功了，但是打开别的Component，发现数据并没有刷新，这样用户体验不是特别友好。

打开其它Component↓↓↓↓↓↓

改善方法是在头部引入【refreshApex】，然后在更新成功之后进行刷新处理。

更新后：↓↓↓↓↓↓

看下边测试效果，初期数据取得从【getRecord】改成Apex之后，虽然在更新成功时调用方法【refreshApex】，但还是没有刷新其它Component的数据。

打开其它Component↓↓↓↓↓↓

解决方法是调用方法【getRecordNotifyChange】，可以对指定RecordId的数据进行取得，更新并更新Lightning Data Services缓存，修改后的dreamHouseOpportunityEditForm4.js

数据已经自动刷新。
