vue+elementui 实现新增和修改共用一个弹框

一、新增
1、新增按钮

2、新增事件 在methods中，用来打开弹窗，
dialogVisible在data中定义使用有true或false来控制显示弹框

 
**3、新增确定，弹框确定事件 ，新增和修改共用一个确定事件，使用id区别

**3、新增事件
调新增接口，判断是否有id，没有就调新增接口

二、修改
2-1、修改按钮 ，表格行编辑按钮使用scope.row拿到当前行的数据

2-2、修改事件， 把当前行数据赋值给表单，就把当前行数据回显出来了

2-3、修改事件

修改接口，判断是否有id，有就调修改接口**

下面直接上代码了
