Question

I have JSON/JS like this that populates data:

  var settingDefs = [];
  settingDefs.push({
    name:'responses', label:'Responses', type:'aeditor', 
    defaultValue: Object.toJSON([
      {"id":"1", "name":"Bob", "text":"Is here"},
      {"id":"2", "name":"James", "text":"Online"},
    ])
  });

How would I retrieve an entry say if I had “1” and I wanted to lookup using that “1” to retrieve the name/text for that entry (entry 1)?

Assuming that each defaultValue property will be an Array and not a JSON string – you should iterate through the settingDefs array and return all (or maybe just the first?) entry in the defaultValue property whose id matches the one you have. Something like this:

function lookupValueById(sds, id) {
  for (var i=0; i<sds.length; i++) {
    for (var j=0; j<sds[i].defaultValue.length; j++) {
      var el = sds[i].defaultValue[j];
      if (el.id == id) return el;
    }
  }
  return null;
}
lookupValueById(settingDefs, 1); // => {id:'1', name:'Bob', text:'Is Here'}
