Question

我创建了一个正在使用jQuery validate的表单，我需要移动两个字段的错误消息，因此我在此处找到了一个示例，该示例演示了如何执行此操作，并且效果很好。除了现在，“必填”字段并非全部可用。这是我的表单代码：

<form id="myForm"> 
  <div class="form-group">
    <label for="x_po_num">Account Number</label>
    <input type="text" class="form-control" name="x_po_num" id="x_po_num">       
  </div>
  <div class="form-group">
      <label for="x_invoice_num">Invoice Number</label>
      <div class="input-group">
        <div class="input-group-addon">9</div> 
        <input class="form-control" name="x_invoice_num" id="x_invoice_num" data-error="#invError">
      </div>         
      <div id="invError"></div>
  </div>        
  <div class="form-group">
      <label for="x_reference_3">Reference Number</label>
      <input class="form-control" name="x_reference_3" id="x_reference_3" placeholder="Optional" >          
  </div>
  <div class="form-group">
      <label for="x_amount">Amount</label>
      <div class="input-group">
        <div class="input-group-addon">$</div>              
        <input class="form-control" name="x_amount" id="x_amount" data-error="#amtError">
      </div>
      <div id="amtError"></div>
  </div>     
  <input class="btn btn-primary" value="Pay With Your Credit Card" type="submit"> 
</form>

这是我的jQuery验证代码：

$( "#myForm" ).validate({
    rules: {
      x_po_num: {
        required: true,
        digits: true,
        minlength: 11,
        maxlength: 11
      },
      x_invoice_num: {
        required: true,
        digits: true,            
        maxlength: 9,
        minlength: 7,
        normalizer: function( value ) {
          var inv = value;
          inv = "9" + inv;             
          return inv;             
        } 
      },
      x_reference_3: {
        digits: true,
        maxlength: 9,
      },
      x_amount: {
        required: true,
        number: true
      }
    },
    messages: {              
      x_po_num: {
        required: "Please enter an account number",
        minlength: "The account number must be 11 digits long",
        maxlength: "The account number must be 11 digits long",
        digits: "Please enter digits only, no spaces"
      },
      x_invoice_num: {
        required: "Please enter an invoice number",         
        maxlength: "The invoice number must be 10 digits or less",
        minlength: "The invoice number must be at least 8 digits long",
        digits: "Please enter digits only, no spaces"
      },
      x_reference_3: {
        digits: "Please enter digits only",
        maxlength: "The reference number must be 9 digits or less"
      },
      x_amount:{
        required: "Please enter an amount"
      }

    },
    errorPlacement: function(error, element) {
      var placement = $(element).data('error');
      if (placement) {
        $(placement).append(error)
      } else {
        error.insertAfter(element);
      }
    }   
});

这是问题所在：

我需要移动错误消息的两个字段（发票编号和金额）现在位于正确的位置。但是，如果我打开表单并在未输入任何数据的情况下点击“提交”，则我期望发票编号会出现错误，提示“请输入发票编号”，但不会。它根本不显示任何错误。

原来是归一化功能。我将其取出，并在onSubmit处添加了数字并解决了问题。
