Hello, I have problem when I want to sort a list of object that have field on javascript language. Because .Sort() just work on strings and numbers (sort the object itself, cannot sort the object based field that object have). For example, I have this object:

var obj = [
        { name: 'Lazslo', country: 'Philiphine' },
        { name: 'Cecilia', country: 'Vietnam' },
        { name: 'Margareta', country: 'China' }
    ];

The solution is We just have to create function like this:

function compare(a,b) {
  if (a.name < b.name)
     return -1;
  if (a.name > b.name)
    return 1;
  return 0;
}

and apply the function as obj.sort(compare) or we can done it as inline script: objs.sort(function(a,b) {return (a.name > b.name) ? 1 : ((b.name > a.name) ? -1 : 0);} );
