How to determine if Javascript array contains an object with an attribute that equals a given value?

Question

I have an array like

vendors = [{
    Name: \'Magenic\',
    ID: \'ABC\'
  },
  {
    Name: \'Microsoft\',
    ID: \'DEF\'
  } // and so on... 
];
         


        

Answer 1

You cannot without looking into the object really.

You probably should change your structure a little, like

vendors = {
    Magenic:   'ABC',
    Microsoft: 'DEF'
};

Then you can just use it like a lookup-hash.

vendors['Microsoft']; // 'DEF'
vendors['Apple']; // undefined
