From Really Easy Field validation :

• validate-one-required (At least one textbox/radio element must be selected in a group – see below*)

*To use the validate-one-required validator you must first add the class name to only one checkbox/radio button in the group (last one is probably best) and then place all the input elements within a parent element, for example a div element. That way the library can find all the checkboxes/radio buttons to check and place the validation advice element at the bottom of the parent element to make it appear after the group of checkboxes/radio buttons.

Therefore you could do this:

<fieldset>
    <input class="checkbox" type="checkbox" name="checkbox[]" />
    <input class="checkbox" type="checkbox" name="checkbox[]" />
    <input class="checkbox" type="checkbox" name="checkbox[]" />
    <input class="checkbox" type="checkbox" name="checkbox[]" />
    <input class="checkbox validate-one-required" type="checkbox" name="checkbox[]" />
</fieldset>

But since those checkboxes share the same name (this isn't documented but is in the source) you could also do:

<!-- Maybe these are columns and don't share a parent element -->
<div>
    <input class="checkbox" type="checkbox" name="checkbox[]" />
    <input class="checkbox" type="checkbox" name="checkbox[]" />
    <input class="checkbox validate-one-required-by-name" type="checkbox" name="checkbox[]" />
    <!-- This checkbox is lowest on the page so should have the message -->
</div>
<div>
    <input class="checkbox" type="checkbox" name="checkbox[]" />
    <input class="checkbox" type="checkbox" name="checkbox[]" />
</div>

在类中添加required-entry

<input type="checkbox" id="id" name="name" value="value" class="checkbox required-entry">

Answer 3

只要输入共享相同的名称，就可以使用： validate-one-required-by- name（通常是这种情况）
