change checkbox values using a javascript array

Question

I have an javascript array filled with values of checkboxes in a html file. How can i find the specific element and change checksign from jquery.

jQuery.each(substr, function() {
 var n = this;
 $('input[type=checkbox]').each(function () {
 $('input[name='+n+']').attr('checked', true);
 });
});

Substr is the array filled with names. substr = {'a', 'b', 'c', 'd'} .The above code does not work. please help

I think substr = {'a', 'b', 'c', 'd'} should be substr = ['a', 'b', 'c', 'd'].

jQuery.each(substr, function(i, val) {
 // val = a, b, c... etc
 $('input[type=checkbox][name="'+ val +'"]').attr('checked', true);
});

Yes, added like that only for display purpose ;)

it worked like this jQuery.each(substr, function(i, val) { $('input[type=checkbox][value="'+ val +'"]').attr('checked', true); });
