ts代码实现
let expRowKeys: any = ref([]);
let expHospitalRowKeys: any = ref([]);
const getInnerData = (expanded, record) => {
expHospitalRowKeys.value = [];
if (expanded) {
// 只展开一行
if (expRowKeys.value.length > 0) {
//进这个判断说明当前已经有展开的了
//返回某个指定的字符串值在字符串中首次出现的位置，下标为0
let index = expRowKeys.value.indexOf(record.key);
if (index > -1) {
//如果出现则截取这个id,1d到1相当于0，针对重复点击一个
expRowKeys.value.splice(index, 1);
} else {
//如果没出现则截取所有id,添加点击id，0到1，针对已经有一个展开，点另一个会进入判断
expRowKeys.value.splice(0, expRowKeys.value.length);
expRowKeys.value.push(record.key);
}
} else {
//数组长度小于0，说明都没展开，第一次点击，id添加到数组，数组有谁的id谁就展开
expRowKeys.value.push(record.key);
}
hospitialData.length = 0;
hospitialData.push(…record.automationHospitals);
} else {
expRowKeys.value = [];
}
};
//分页
let page = ref(1);
let limit = ref(10);
let total = ref(0);
const onPageChange = (pages, pageSize) => {
page.value = pages;
limit.value = pageSize;
searchList();
};
const onSizeChange = (pages, pageSize) => {
page.value = pages;
limit.value = pageSize;
searchList();
};
