Joins in Javascript

Question

I have 2 lists of objects:

people = 
[{id: 1, name: \"Tom\", carid: 1},
 {id: 2, name: \"Bob\", carid: 1},
 {id: 3, name: \"Sir Benjamin Rogan-Josh IV\", car         


        

Answer 1

Here's a simple loop I did for a Javascript (JQuery in this case) to "join" obj1 and obj2 on someID and add one property from obj2 to obj1.

If you want to do a more complete join, you can go through and expand it to loop on obj2.hasOwnProperty() and copy that over as well.

    $.each(obj1,function(i){
        $.each(obj2, function(k){
            if (obj2[k].someID == obj1[i].someID ){
                obj1[i].someValue = obj2[k].someValue;
            }
        });
     });
