Tengo array arr1, arr2, arr3 y object array objarr
Me gustaría obtener una matriz de objetos según la condición.
es decir, al pasar arr1, la matriz de objetos objarr debe devolver solo las claves coincidentes de arr1
es decir, al pasar arr2, la matriz de objetos objarr debe devolver solo las claves coincidentes de arr2 (si se pasa a wrk , el parámetro solo muestra que es verdadero)
es decir, al pasar arr3, la matriz de objetos objarr debe devolver solo las claves coincidentes de arr3
var arr1=["name", "place"] var arr2=["details", "wrk"] var arr3=["name"] var objarr=[ {id:1, name: "ayan", place: "MY", details: "finance" , wrk: true}, {id:2, name: "mike", place: "AU", details: "teaching", wrk: false }, {id:3, name: "john", place: "DE", details: "service" , wrk: true} ] function outputData(arr1){ var final=[]; var result = objarr.map(e=>{ if(arr1.includes(Object.keys(e)){ final.push(e) } }) return final ;} Expected Output; //for arr1 is passed [ {name: "ayan", place: "MY"}, {name: "mike", place: "AU"}, {name: "john", place: "DE"} ] //for arr2 is passed [ {details: "finance", wrk:true}, {details: "service", wrk: true} ] //for arr3 is passed [ {name: "ayan"}, {name: "mike"}, {name: "john"} ] var arr1 = ["name", "place"]; var arr2 = ["details", "wrk"]; var arr3 = ["name"]; var objarr = [ { id: 1, name: "ayan", place: "MY", details: "finance", wrk: true }, { id: 2, name: "mike", place: "AU", details: "teaching", wrk: false }, { id: 3, name: "john", place: "DE", details: "service", wrk: true } ] function outputData(arr) { var final = []; objarr.forEach(obj => { const temp = {}; arr.forEach(key => { if(obj[key]){ temp[key]= obj[key]; } }); if(Object.keys(temp).length===arr.length){ final.push(temp);} }); return final; } console.log('arr1',outputData(arr1)); console.log('arr2',outputData(arr2)); console.log('arr3',outputData(arr3));Dado que solo necesita seleccionar nodos específicos de objarr , ir a Array.map no dará el resultado. Use alguna otra lógica de bucle para eso.
Array.reduce aquí.
Lógica
objarr con Array.reduce .objarr .Tenga en cuenta: esta lógica verifica el valor real solo para la clave "wrk". Si desea verificar todos los valores booleanos, puede usar la condición agregada como comentario justo encima de la declaración if
var arr1 = ["name", "place"] var arr2 = ["details", "wrk"] var arr3 = ["name"] var objarr = [ { id: 1, name: "ayan", place: "MY", details: "finance", wrk: true }, { id: 2, name: "mike", place: "AU", details: "teaching", wrk: false }, { id: 3, name: "john", place: "DE", details: "service", wrk: true } ] function outputData(arr) { var result = objarr.reduce((acc, currNode) => { const resp = {}; arr.forEach((option) => { // Current condition is only for "wrk" // To check truthy state for all boolean variables use the below condition // ((typeof currNode[option] === "boolean" && currNode[option]) || typeof currNode[option] !== "boolean") if ((option === "wrk" && currNode[option]) || option !== "wrk") { resp[option] = currNode[option] } }) if(Object.keys(resp).length === arr.length) { acc.push(resp) } return acc }, []); return result; } console.log(outputData(arr1)); console.log(outputData(arr2)); console.log(outputData(arr3));Puede lograr fácilmente el resultado usando reduce y for..of loop
var arr1 = ["name", "place"]; var arr2 = ["details", "wrk"]; var arr3 = ["name"]; var objarr = [ { id: 1, name: "ayan", place: "MY", details: "finance", wrk: true }, { id: 2, name: "mike", place: "AU", details: "teaching", wrk: false }, { id: 3, name: "john", place: "DE", details: "service", wrk: true }, ]; function getData(target, source) { return target.reduce((acc, curr) => { const obj = {}; for (let prop of source) { obj[prop] = curr[prop]; } if (Object.keys(obj).includes("wrk")) { if (obj["wrk"]) acc.push(obj); } else acc.push(obj); return acc; }, []); } console.log(getData(objarr, arr1)); console.log(getData(objarr, arr2)); console.log(getData(objarr, arr3)); /* This is not a part of answer. It is just to give the output fill height. So IGNORE IT */ .as-console-wrapper { max-height: 100% !important; top: 0; }
