const items = [[{name:"p2"},{name:"p3"}, {name:"p7"},{name:"p9"},{name:"p1"}],[{name:"p6"}, {name:"p3"},{name:"p7"}, {name:"p9"},{name:"p2"}],[{name:"p3"},{name:"p6"}, {name:"p7"},{name:"p9"},{name:"p4"}],[{name:"p2"}, {name:"p3"},{name:"p1"}, {name:"p9"},{name:"p6"}]]
const findObj = [{name:"p1"},{name:"p2"},{name:"p6"}]
Locate the array within the sets that contains all three elements from the findobj object
To achieve the desired outcome, you can utilize filter, Set, and reduce. Here's an example:
const items = [
[
{ name: "p2" },
{ name: "p3" },
{ name: "p7" },
{ name: "p9" },
{ name: "p1" },
],
[
{ name: "p6" },
{ name: "p3" },
{ name: "p7" },
{ name: "p9" },
{ name: "p2" },
],
[
{ name: "p3" },
{ name: "p6" },
{ name: "p7" },
{ name: "p9" },
{ name: "p4" },
],
[
{ name: "p2" },
{ name: "p3" },
{ name: "p1" },
{ name: "p9" },
{ name: "p6" },
],
];
const findObj = [{ name: "p1" }, { name: "p2" }, { name: "p6" }];
const set = new Set(findObj.map((o) => o.name));
const result = items.filter((arr) => {
const remain = arr.reduce((acc, curr) => {
if (set.has(curr.name)) acc.add(curr.name);
return acc;
}, new Set());
return remain.size === set.size;
});
console.log(result);const elements = [[{name:"p2"},{name:"p3"}, {name:"p7"},{name:"p9"},{name:"p1"}],[{name:"p6"}, {name:"p3"},{name:"p7"}, {name:"p9"},{name:"p2"}],[{name:"p3"},{name:"p6"}, {name:"p7"},{name:"p9"},{name:"p4"}],[{name:"p2"}, {name:"p3"},{name:"p1"}, {name:"p9"},{name:"p6"]]
const searchValues = [{name:"p1"},{name:"p2"},{name:"p6"}]
const results = elements.filter(item=>{
const itemsArr = item.map(childItem=>childItem.name);
let allFound=true;
searchValues.forEach(obj=>{
if(!itemsArr.includes(obj.name)){
allFound=false;
}
})
return allFound;
})
console.log(results)To extract all names from each item in an array using filter and map, you can use .map(prop=>prop.name) or a simpler method with destructuring like .map(({name})=>name. Then, filter the items based on whether their names are included in findObj.
const items = [[{name:"p2"},{name:"p3"}, {name:"p7"},{name:"p9"},{name:"p1"}],[{name:"p6"}, {name:"p3"},{name:"p7"}, {name:"p9"},{name:"p2"}],[{name:"p3"},{name:"p6"}, {name:"p7"},{name:"p9"},{name:"p4"}],[{name:"p2"}, {name:"p3"},{name:"p1"}, {name:"p9"},{name:"p6"}]]
const findObj = [{name:"p1"},{name:"p2"},{name:"p6"}]
const result = items.filter(item=>{
const arrProp = item.map(prop=>prop.name)
const filtProp = findObj.map(({name})=>name)
return filtProp.every(x=>arrProp.includes(x));
})
