Question

如何在每个逗号分隔的情况下仅允许和验证10封电子邮件或最少。它应该只允许10封电子邮件或最少，每封电子邮件都以逗号分隔。现在我只能验证用逗号分隔的每封电子邮件

    <form method="post" action="" id="add_engagement" name="add_engagement" class="form-horizontal">
<tr><td>Email Recipients</td>
    <td><textarea name="email_recipients"  id="email_recipients" >{$Notification.email_recipients}</textarea><br/><span style="color:red">*</span>Note: Separated by commas(,)</td>
</tr>
 <input type="submit" class="post_button" id="edit_notification" value="Update" name="edit_notification" /></td></tr>
</form>


<script>    
$(function(){
$('#edit_notification').one('click', function () {
jQuery.validator.setDefaults({
      debug: true,
      success: "valid"
    });
$.validator.addMethod('multiEmails', function(value, element) {
    if (this.optional(element)) {
        return true;
    } else {
        var valid = true;

        $.each($.trim(value).replace(/,$/, '').split(','), $.proxy(function (index, email) {
            if (!$.validator.methods.email.call(this, $.trim(email), element)) {
                valid = false;
            }
        }, this));

        return valid; 
        }
    }, 'One or more email addresses are invalid');

$("#add_engagement").validate({

    rules: {

        email_recipients: {
                required: true,
                multiEmails:true,

            },  
        },
        messages: {

        email_recipients: {
        required: "Please enter email",

        },
    },
    submitHandler: function(form) {
            form.submit();
    },
});<script>

您可以添加计数器：

SELECT LicensePlateNo FROM car
  LEFT JOIN CarTransaction ON car.ChassisNo = CarTransaction.ChassisNo 
  LEFT JOIN Sell ON CarTransaction.TransactionID = Sell.TransactionID
  LEFT JOIN Rent ON CarTransaction.TransactionID = Rent.TransactionID
  WHERE Car.Make = 'Toyota'
    AND Sell.TransactionID IS NULL
    AND Rent.TransactionID IS NULL

或者您可以在电子邮件地址数量上添加另一个验证规则，并附带单独的错误消息。

在每个逗号分隔的Jquery验证中最多允许10个电子邮件
