Question

I have array object(x) that stores json (key,value) objects. I need to make sure that x only takes json object with unique key. Below, example \'id\' is the key, so i don\'t

Answer 1

You can't use inArray() because you are searching for an object.

I'd recommend rewriting a custom find using Array.some() as follows.

var x = [{"id":"item1","val":"Items"},{"id":"item1","val":"Items"},{"id":"item1","val":"Items"}]    

var clickId = "item1";
var found = x.some(function(value) {
  return value.id === clickId;
});
alert(found);
