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 need to access the result object on iteration.

for (var key in result)
{
   if (result.hasOwnProperty(key))
   {
      // here you have access to
      var MNGR_NAME = result[key].MNGR_NAME;
      var MGR_ID = result[key].MGR_ID;
   }
}

Answer 2

You can iterate over the collection and check each object if it contains the property:

var count = 0;
var i;
for(i = 0; i < jsonObj.length; i += 1) {
    if(jsonObj[i]["MNGR_NAME"]) {
        count++;
    }
}
