Question

我有一张表格。如果将select字段设置为第一个选项，那么我必须设置两个无线电组。如果将select设置为任何其他值，则不必设置它们。

选择：

<div class="field grid_10">
    <label for="severityId" class="grid_3">Severity</label>
    <div class="grid_6"> 
        <form:select id="severityId" path="severityId" items="${severityList}" itemValue="id" itemLabel="title" />
    </div>
    <div class="clear"> </div>
</div>

验证：

 function validate_eventReviewForm() {      

    jQuery('#review-edit-form').validate ({
        rules: {
            sampleWasLost: {required: {
                depends: function(element){
                    return $("#severityId").val() == 1
                }}},
            backupSampleAvail: {
                depends: function(element){
                    return $("#severityId").val() == 1
                }}
        }
    });
}

正如您所看到的，我尝试了两种不同的方法来让jQuery根据需要进行标记。两者都不起作用。

我做错了什么？我如何使这项工作？

问题是您的第二个脚本导致错误，导致验证失败

jQuery(function($) {
  $('#review-edit-form').validate({
    rules: {
      sampleWasLost: {
        required: {
          depends: function(element) {
            return $("#severityId").val() == 1
          }
        }
      },
      backupSampleAvail: {
        required: {
          depends: function(element) {
            return $("#severityId").val() == 1
          }
        }
      }
    }
  });
});
