一、问题，重现步骤
步骤一
步骤2
步骤3
二、原因
在'新增子项'的按钮里面，他是这么写的
三、解决
有两种思路
- 在新增的时候，把值都重置到初始状态
- 在关闭页面的时候，把值都重置到初始状态
这里我选择的第二种
增加一个事件
:before-close="beforeClose"
事件的具体代码
beforeClose(done, type) {
if (["add"].includes(type)) {
this.$refs.crud.value.parentId = '';
this.$refs.crud.option.column.filter(item => {
if (item.prop === "parentId") {
item.value = '';
item.addDisabled = false;
}
});
}
done();
},
