Tengo un objeto de muestra, necesito reasignar el valor dinámicamente.
aquí hay un objeto de muestra, he almacenado el objeto en dynamodb con el tipo de datos inarray. He formado el objeto usando loop. No pude usar el valor payload.offer. amablemente sugiera la mejor solución.
{ organization_id: 4002400004, organization_name: 'Velocity Global Integration Sandbox', 'payload.offer': 'payload offer', }Formato de salida requerido
{ organization_id: 4002400004, organization_name: 'Velocity Global Integration Sandbox', 'payload': { offer: 'payload offer' }, }Según tengo entendido, desea una forma de convertir de notación de puntos a objetos profundamente anidados. Puedes probar lo siguiente entonces:
function dotToNested(obj) { return Object.entries(obj).reduce((newObj, [key, value]) => { const path = key.split("."); // This part makes it recursive, you can just use value if you don't want that const newValue = typeof value === "object" && !!value ? dotToNested(value) : value; if (path.length > 1) { // Last key will be used for assignment const newKey = path.pop(); // Get the object to assign to, and create the intermediate objects along the way const objRef = path.reduce((ref, key) => { // create the intermediate object ref[key] = {}; // move further down in the deeply nested structure return ref[key]; }, newObj); objRef[newKey] = newValue; } else { // Just a "regular" key, assign directly to it, no need for the path newObj[key] = newValue; } return newObj; }, {}); } const dotNotation = { organization_id: 4002400004, organization_name: 'Velocity Global Integration Sandbox', 'payload.offer': 'payload offer', }; const deeplyNested = dotToNested(dotNotation); console.log({ dotNotation, deeplyNested });Puede usar el método de nivel superior Object.keys() del prototipo de objeto estándar y dividir ('.') la clave de destino e intentar eliminar la clave anterior y agregar la clave nueva.
Bueno, esta es mi sugerencia de código.
const input = { organization_id: 4002400004, organization_name: 'Velocity Global Integration Sandbox', 'payload.offer': 'payload offer', }; function modify(input, requireKey) { const newObject = {}; Object.keys(input).forEach((key) => { if (key === requireKey) { let [newKey, newDownLevelKey] = key.split('.'); delete Object.assign(newObject, input, { [newKey]: input[key], })[key]; newObject[newKey] = { [newDownLevelKey]: newObject[newKey], }; } }); return newObject; } console.log(modify(input, 'payload.offer'));Recursos :
