Determining if all attributes on a javascript object are null or an empty string
Check all values with Object.values. It returns an array with the values, which you can check with Array.prototype.every or Array.prototype.some:
const isEmpty = Object.values(object).every(x => x === null || x === '');const isEmpty = !Object.values(object).some(x => x !== null && x !== '');
Create a function to loop and check:
function checkProperties(obj) { for (var key in obj) { if (obj[key] !== null && obj[key] != "") return false; } return true;}var obj = { x: null, y: "", z: 1}checkProperties(obj) //returns false
Here's my version, specifically checking for null and empty strings (would be easier to just check for falsy)
function isEmptyObject(o) { return Object.keys(o).every(function(x) { return o[x]===''||o[x]===null; // or just "return o[x];" for falsy values });}
