jquery multiple checkboxes array

Question

<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!

Answer 1

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

Answer 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
