//此時result：[兒科焕济，神經(jīng)外科，普通外科，兒科祥国，普通外科]，然后數(shù)組對象根據(jù)某個key相同合并分組
function resultList(result) {
// console.log(result)
let obj = {};
result.forEach((item, index) => {
let = item;
if (!obj[b]) {
obj[b] = {
b,
data: []
}
}
obj[b].data.push(item);
})
let data = Object.values(obj)
console.log(data)
}
resultList(result.data)
最終想要的理想數(shù)據(jù)
