                                    var json = [
    {&quot;text&quot;:&quot;menu1&quot;,&quot;parent&quot;:&quot;#&quot;,&quot;id&quot;:&quot;128102&quot;},
    {&quot;text&quot;:&quot;menu1.1&quot;,&quot;parent&quot;:&quot;128102&quot;,&quot;id&quot;:&quot;128103&quot;},
    {&quot;text&quot;:&quot;menu1.1&quot;,&quot;parent&quot;:&quot;128102&quot;,&quot;id&quot;:&quot;128103&quot;}
];

var ids = [];
var clean = [];

$.each(json, function(index, value) {
    if($.inArray(value.id, ids) == -1)
    {
        ids.push(value.id);
        clean.push(value);
    }
});

Thank you! 9
