You can use the following solution to solve your problem:

var mychecked = $('.selectsms:checked').length

if (mychecked==0) {
    alert("Please choose at least one checkbox");
}

if you have checkbox in multiple classes. and want to find only a specific class's checked box count then this will be definitely helpful.

var numberOfChecked = $(divId).find(".checkbutton").find(":checkbox:checked").length;
alert(numberOfChecked);

<input type='checkbox' checked='checked' class='A' />
<input type='checkbox' class='A' />
<input type='checkbox' checked='checked' class='A' />
<input type='checkbox' checked='checked' class='A' />
<input type='checkbox' checked='checked' class='A' />

<input type='checkbox' checked='checked' class='B' />
<input type='checkbox' checked='checked' class='B' />
<input type='checkbox' checked='checked' class='B' />

4 class="A" input boxes are checked

alert($('.A:checked').length)

With this:

var classAChecked = $(".myClassA:checkbox:checked").size();

The :checkbox selector selects all checkboxes, while the :checked filters only the checked ones.

Hope this helps
