assigning new value to an object in object array in jquery

Question

I have an array of objects

object will be in below format

var newUserDetail={"Age":"21","name":"Vicky","UserId":"198303"};

Now I am trying to compare UserId and replace the values

//usersList contains array of newUserDetail kind of objects

jQuery(usersList).each(function(){
if(this.UserId==newUserDetail.UserId){
this=newUserDetail;
}
});

But it throws an error

Invalid left-hand side in assignment

i think it's probably because "this" inside the if condition, and why this=newUserDetail; ? — himawan_r

Set the array entry:

jQuery(usersList).each(function (i) {
    if (this.UserId == newUserDetail.UserId) {
        usersList[i] = newUserDetail;
        return false; //if you want to break the loop
    }
});

Try this

$(document).ready(function() {
  var newUserDetail = {
    "Age": "21",
    "name": "Vicky",
    "UserId": "198303"
  };

  var tm = {
    "Age": "21",
    "name": "Vicky",
    "UserId": "198303"
  };
  $.each(newUserDetail, function(k, i) {
    if (i == tm.UserId) {
      alert("User ID match");
    }


  })



})
