您可以将Arrays.filter用于 JSON 数组中每个外部对象中的组项目,以过滤掉与您的搜索查询匹配的项目。你可以这样写:
let autocomplete = (key) => {
// arr = Your Data
let result = []
arr.forEach(grp=> {
let out = grp
let res = grp.groupItems.filter(item => item.name.toLowerCase().includes(key.toLowerCase()))
if(res.length!=0)
{
out.groupItems = res
result.push(out)}
})
return result

在实施此之前,我肯定会尝试通过您尝试做的事情进行推理。能够通过这样的解决方案进行推理是编程工作的 99%。
function filterGroups(filter) {
const result = [];
myObj.forEach(group => {
const filteredGroups = group.groupItems.filter(groupItem => {
return groupItem.name.toLowerCase().includes(filter);
});
if (filteredGroups.length > 1) {
result.push({
...group,
groupItems: filteredGroups
});
}
});
return result;
}
