Remove empty Objects from Array

Question

I have a JavaScript-array with objects filled in and want to remove every object with no data. It might look like this:

var myArray = [ {id: "28b", text:"Phill"},
                {id: "12c", text:"Peter"},
                {id: "43f", text:"Ashley"},
                {id: "43f", text:"Ashley"},
                {id: "", text:""},
                {id: "9a", text:"James"},
                {id: "", text:""},
                {id: "28b", text:"Phill"}
              ];

I already use _.uniq from underscore.js to remove all duplicates from my array, which works fine. Though they are unique, one empty Object is always left when I dynamically fill in data (because there are empty datasets). I already tried the _.without function as mentioned here: Remove empty elements from an array in Javascript but it doesn't work. Here is my attempt:

myArray = _.without(myArray, {id:"",text:""});

The array should look like this:

              [ {id: "28b", text:"Phill"},
                {id: "12c", text:"Peter"},
                {id: "43f", text:"Ashley"},
                {id: "9a", text:"James"},
              ];

I am also using jQuery if there is a solution with this library.

You can try this:

_.filter(myArray, _.isEmpty)

I assume empty means

var obj = {}
