I know how to loop through array to get value... but I don't know how to use it to assign data name in ajax. is it possible to do this?

<script>
    var my_array = ["orange", "apple", "banana"];

    $.post(url, {
    orange: 'orange',     //I want to use value in array to define data name in ajax
    apple: 'apple',
    banana : 'banana' 
    }, function (data) {

                alert("Success Post Data!");
                });
            });

/////// so I want something like this

    $.post(url, {
    my_arr[0]: 'my_arr[0]',    
    my_arr[1]: 'my_arr[1]',
    my_arr[2] : 'my_arr[2]',
    .......................
    my_arr[n] :  'my_arr[n] 
    }, function (data) {

                alert("Success Post Data!");
                });
            });

but don't know how to do it. How could I do?

Create a object first and the post what i understand u want the value of ur array as key

var postObject = {};
postObject[my_arr[0]] = 'my_arr[0]';
...
postObject[my_arr[n]] = 'my_arr[n]';

then post that object

$.post(url, postObject, function (data) {

                alert("Success Post Data!");
                });
            });

yes, its possible:

var my_array = ["orange", "apple", "banana"];
var dataToSend = {};
my_array.forEach(function(d){
   dataToSend[d] = d;
});
$.post(url, dataToSend, function (data) {
      alert("Success Post Data!");
    });
});
