Question

I have this piece of code in Javascript:

var len = 0;
$('#list > input').each(function() {
    if($(this).attr('checked')) len++;
});
if(!len) {
    alert("{$err.no_list_chosen}");
    return false;
}
return checkFormAdd();

It should iter the list of checkbox to be sure that AT LEAST one is checked, otherwise, return Error.
All this is not working on Internet Explorer 8, and maybe on 7 too.
Can someone help me to rewrite the code so that it could be good for all the browsers?

Answer 1

Please, just use one line:

var amountOfChecked = $('#list > input:checked').length;

It works in all browsers, just like your code, but this is without the spaghetti…
