Get JavaScript object from array of objects by value of property [duplicate]

Answer 1

Try Array filter method for filter the array of objects with property.

var jsObjects = [
   {a: 1, b: 2}, 
   {a: 3, b: 4}, 
   {a: 5, b: 6}, 
   {a: 7, b: 8}
];

using array filter method:

var filterObj = jsObjects.filter(function(e) {
  return e.b == 6;
});

using for in loop :

for (var i in jsObjects) {
  if (jsObjects[i].b == 6) {
    console.log(jsObjects[i]); // {a: 5, b: 6}
  }
}
