jquery multiple checkboxes array

<input type="checkbox" name="options[]" value="1" />
<input type="checkbox" name="options[]" value="2" />
<input type="checkbox" name="options[]" value="3" />
<input type="checkbox" name="options[]" value="4" />
<input type="checkbox" name="options[]" value="5" />

How I can make an array with values of checkboxes that are checked?

NOTE: (IMPORTANT) I need an array like [1, 2, 3, 4, 5] and not like ["1", "2", "3", "4", "5"] .
NOTE: There are around 50 checkboxes.

Can someone help me? Please!

Thank you!

Solution 1:

var checked = []
$("input[name='options[]']:checked").each(function ()
{
    checked.push(parseInt($(this).val()));
});

Solution 2:

You can use $.map() (or even the .map() function that operates on a jQuery object) to get an array of checked values. The unary (+) operator will cast the string to a number

var arr = $.map($('input:checkbox:checked'), function(e,i) {
    return +e.value;
});

console.log(arr);

Here's an example

Solution 3:

var checkedString = $('input:checkbox:checked.name').map(function() { return this.value; }).get().join();
