avue-crud组件 表格回显实现

avue框架

最近用到了avue框架，在实现表格项目回显的时候，遇到了一些问题，特再次做了记录，也希望对遇到相同问题的码友，有所帮助

crud组件

avue中crud组件可以实现很多功能，可以通过不同的配置项，来实现表格的展示、搜索、分页等功能，本文主要讲述在表格多选中，对需要回显的项进行勾选，以及提交数据时，发送修改后的数据传给服务端

实现回显的核心代码

 let selectedItems = []
 selectedItems = this.data.filter(item => this.currSelection.includes(item.id.toString()))
 const selectedItemIds = selectedItems.map(ele => ele.id);
 this.$refs.crud.toggleSelection(selectedItems);
 if(selectedItems.length){
     this.currSelection = this.currSelection.filter(item => !selectedItemIds.includes(+item))
 }
