How to loop through JSON array?

Question

I have some JSON-code which has multiple objects in it:

[
    {
        \"MNGR_NAME\": \"Mark\",
        \"MGR_ID\": \"M44\",
        \"EMP_ID\": \"1849\"
           


        

Answer 1

You could use jQuery's $.each:

    var exists = false;

    $.each(arr, function(index, obj){
       if(typeof(obj.MNGR_NAME) !== 'undefined'){
          exists = true;
          return false;
       }
    });

    alert('Does a manager exists? ' + exists);

Returning false will break the each, so when one manager is encountered, the iteration will stop.
