In a loop I have some checkboxs that I set a class name :

class="ids[]"

Because my loop is inside a form,at first time I want to find out any checkbox is check or not.

var ids = new Array();

$('.ids[]').each(function(index, element) { 
    if(this.checked) {
        ids.push($(this).val());
    }
});

if(ids.length == 0 ) {
    alert('not checked any checkbox');
    return false;
}

$('.ids[]').each... not fetch anything.

The `[]` are most probably treated by jQuery as attribute selector syntax. Use `.ids\\[\\]` instead, although such class names look very odd. – Rafael Jan 17 '16 at 13:25

why would you ever need (or use) `[]` in a className? – charlietfl Jan 17 '16 at 13:55
you need the square brackets for `name="ids[]"` atrribute, not for the classname – Mi-Creativity Jan 17 '16 at 15:21
