JQuery - Push method JSONArray

Question

I'm doing the push method between two Arrays to create a bigger Array. The two simple arrays I want to fix are:

[{"id":"11"},{"color":"blue","value":"14"}] 
[{"id":"11"},{"color":"green","value":"25"}]

The code to push the two arrays is:

var totjunt = $('body').data('cesta_list').push(array_of_bought_colors_new);

With $('body').data('cesta_list'); I save the first array and then i try to push the second array.

Using console.log(JSON.stringify(totjunt)); I print the value throught the console but the problem is that the console prints only a number 2.

w3schools.com/jsref/jsref_push.asp push returns the new array length, not the new array — Populus

You're logging the result of the push() call, not the resulting array. Try this:

$('body').data('cesta_list').push(array_of_bought_colors_new);
var totjunt = $('body').data('cesta_list');

More specifically, push() returns the length of the new array, not the array itself.

.push doesn't return a new array. It returns the array's new length. The array is updated in-place.
