jQuery验证插件条件必需字段

我遇到了 jQuery validate plugin的问题.我有一组3个单选按钮,如果选择前两个中的任何一个,则在表单上显示用户额外的选择输入,如果选择了第三个,则没有任何反应.

如果他们从单选按钮组中选择选项1或2,我希望用户需要从附加选择输入中选择一些内容.

我已经为第一个选项编写了代码,但它无法正常工作.如果我没有选择任何单选按钮选项,我会得到两个必填字段错误(一个用于单选按钮设置,另一个用于隐藏的选择输入,不应该验证).

select是自定义代码,它有一些jQuery来控制它. jQuery将所选值放入隐藏的输入工资带中

我的代码是：

HTML

<!-- radio button select -->
<label>Earnings</label>
<div class="multiple-select earnings-wrapper clearfix">
    <div class="third">
        <input id="job-earnings-salary" class="trigger" data-type="salary"
        type="radio" name="jobearnings" value="salary" required="true">
        <label for="job-earnings-salary">Salary</label>
    </div>
    <div class="third">
        <input id="job-earnings-hourly" class="trigger" data-type="hourly"
        type="radio" name="jobearnings" value="hourly" required="true">
        <label for="job-earnings-hourly">Hourly</label>
    </div>
    <div class="third">
        <input id="job-earnings-unspecified" class="trigger" data-type="none"
        type="radio" name="jobearnings" value="unspecified" required="true">
        <label for="job-earnings-unspecified">Unspecified</label>
    </div>
    <input type="hidden" name="earningstype" id="earnings-type" class="trigger-input" value="">
</div>


<!-- First select Box -->
<label for="salaryband">Salary Band</label>
<div class="select">
    <span class="select-default">Select Salary Band</span>
    <div class="options">
    <?PHP
        $args = array(
            'hide_empty' => false,'orderby' => 'ID',);
        $salaries = get_terms('salaries',$args);
        foreach( $salaries as $salary ) :
            echo '<span data-value="'.$salary->term_id.'">'.$salary->name.'</span>';
        endforeach;
    ?>
    </div>
    <input type="hidden" name="salaryband" id="salaryband" class="salary-band" />
</div>

验证jQuery：

$("#client-form").validate({
    focusInvalid: false,ignore: [],rules: {
        salaryband: {
            required: {
                depends: function(element) {
                    return $("#job-earnings-salary:checked");
                }
            }
        }
    }
});

尽管有条件要求的规则,为什么它始终验证选择输入的任何想法？

解决方法

$(“#job-earnings-salary：checked”)返回一个jQuery对象,它始终是真实的

$("#client-form").validate({
  focusInvalid: false,rules: {
    salaryband: {
      required: function(element) {
        return $('#job-earnings-salary').is(':checked')
      }
    }
  }
});
