克隆的输入验证不起作用

Question

我无法验证克隆字段集的输入。我尝试在每次克隆后重新初始化表单验证程序，并为每个克隆的输入添加.rules（＆＃39; add＆＃39; ... required：true），但验证仍然失败。任何帮助将不胜感激......

HTML：

<fieldset class="individual-award">
<legend>Individual Award - Received</legend>
<p class="left">
    <label for="individual-award-organization">Organization Granting Award</label>
    <input type="text" name="individual-award[organization][]" class="required" />

    <label for="individual-award-name">Name of Award</label>
    <input type="text" name='individual-award[name][]' class="required" />

    <label for="individual-award-city-state">City, State</label>
    <input type="text" name="individual-award[city-state][]"  class="required" />


    <label for="individual-award-date">Date Received</label>
    <input type="text" name="individual-award[date][]" class="date-picker required" />
  </p>
</fieldset>

jQuery的：

jQuery(document).ready(function() {

var addBtn = jQuery('<input type="button" value="Add Entry" class="add-entry" style="position: absolute; right: 5px; bottom: 5px;" />');

    jQuery('fieldset[class]').not('.team-award, .bibliography, .interests, .grants-education, .grants-research, .presentations').append(addBtn);

    jQuery('.add-entry, .delete-entry').bind('click', function(){

        if ( jQuery(this).attr('class') == 'add-entry' ) {
            var clone = jQuery(this).closest('fieldset').clone(true);
            var inpts = clone.find(':input:not(:button)');          
            jQuery(this).closest('fieldset').find('.add-entry').attr({'class':'delete-entry', 'value': 'Delete Entry'});

            inpts.val('');  

            clone.find('input.date-picker').removeClass('hasDatepicker').removeAttr('id').datepicker({
                prevText: '',
                nextText: '',
                changeMonth: true,
                changeYear: true,
                yearRange: '1975:2024',
                dateFormat: 'MM d, yy',
                constrainInput: false
            });                         
            clone.insertAfter('fieldset:last');          
        } else  {
            jQuery(this).closest('fieldset').remove();
        }
    });

    jQuery('#reaims-update-form').validate({
        errorPlacement: function(error, element){
            return true;
        },          
        ignore:":hidden"
     });
 });
