There is nothing built in for that...You must run a loop to check duplicates...
Here a sample for you to start with...

JavaScript

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

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

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

The ids array is a helper to check for duplicates and contains only the unique ids from the original array, where clean will hold the actual array with no duplicates...
