Check if at least one checkbox is checked using jQuery

Question

I have five checkboxes. Using jQuery, how do I check if at least one of them is checked?

<         


        

Answer 1

var checkboxes = document.getElementsByName("service[]");
if ([].some.call(checkboxes, function () { return this.checked; })) {
  // code
}

What you want is simple, get all the elements with the name, then run some code if some of those elements are checked.

No need for jQuery.

You may need an ES5 shim for legacy browsers though
