Is there a better way other than looping to find data in JSON? It's for edit and delete.

for(var k in objJsonResp) {
  if (objJsonResp[k].txtId == id) {
    if (action == 'delete') {
      objJsonResp.splice(k,1);
    } else {
      objJsonResp[k] = newVal;
    }
    break;
  }
}

The data is arranged as list of maps. Like:

[{id:value, pId:value, cId:value,...}, {id:value, pId:value, cId:value}, ...]
