ts
// 设置级联选择器的属性
const unitProps = {
checkStrictly: true,//是否严格的遵守父子节点不互相关联
emitPath: false,//是否返回数组
filterable: true//是否可以搜索
};
//改变级联的值并且传值
const unitIdChange = (val: any) => {
//传true为新增，false为编辑
resourceRef.value.getApplyList(val, true);
};
子组件接收的方法
//获取应用系统
const getApplyList = (val: any, isChange: any) => {
//判断是否是change，是change才清空
if (isChange) {
resourceList.value = resourceList.value.map((item: any) => {

return item;
});
}
getApplyListByUnitId(val).then((res: any) => {
applicationOptions.value = res.data;
