There is a request for some information:

<script type="text/javascript"> setInterval(function() { $.getJSON('/test.php', function(data) { alert(data.num); // Π½Π΅ΠΊΠΈΠ΅ значСния }); }, 2000); </script>

For the sake of interest, if 5 identical values fall out in num (for example, alert (1) drops out 5 times), then 4 needs to be deleted and output 1. And all this in JS.

    As an option, write the numbers that have fallen into the array and check before output that this has not happened before (using jQuery)

     var nums = []; setInterval(function() { $.getJSON('/test.php', function(data) { if ($.inArray(data.num, nums)) { alert(data.num); // Π½Π΅ΠΊΠΈΠ΅ значСния nums.push(data.num); } }); }, 2000);

    If you mean that you can not display the same numbers in a row, then just remember the last number and compare with it before displaying

      I would do this:

       function remove (data){ for(var i = 0; i < data.length; i++) for(var j = i+1; j < data.length; j++) if(data[i] == data[j]) data.splice(j, 1); return data; } 
       var data = ['data1',2,3,2,1,'data4',5,6,'data3',8,9,'data4',5,2,'data1']; console.log(remove(data)); //["data1", 2, 3, 1, "data4", 5, 6, "data3", 8, 9]
