自动完成JavaScript

Question

I have some problem in crating an autocomplete search box. I have a mongodb collection in which there are photos object with name, description, path and so on. Now, I created a route /searchbox, where the box is displayed in the browser. Every time that the user press a key, a get request to the route /autocomplete/:query is made. The autocomplete route will search in the collection for all the objects where the name, the description or the keywords fields starts with the give query. Then it return a json object containing all the strings that will be put into a datalist in the view. The problem is that I can't create that json array, I tried to create a json object with a field containing an array, and at every iteration on the found array returned by the find function, I get the field name and push it into the array, but nothing is added... here my code:

exports.autoComplete = function(req, res) {
  var PhotoAlbum = db.model('PhotoAlbum', schemas.PhotoAlbumSchema);
  var regexp = "^"+req.params.query;
  var suggestions = {suggestion: []};

  var strings = "";
  var arrayStrings = [];


  PhotoAlbum.find({name: new RegExp(regexp,"i")}, function(err, found) {
    if(err) throw handleError(err);
    for(obj in found) {
      var name = found[obj].name;
      suggestions.suggestion.push(name);
      strings += name + "|";
    }


  });
}

Thank you

That looks like Mongoosejs with MongoDB.

IF it is, in that case, its not returning an object at "found". "found" is a collection that is an array already in which you would iterate through it like so:

for(var i = 0; i < found.length; i++) {
   console.log(found[i]);
   // your code
}
