如何在span中显示jquery验证错误消息

Question

我有以下脚本来验证我的表单.它工作正常,但我试图显示所有内部的验证错误消息,<span class="errormsg"></span>用逗号分隔,而不是在每个输入旁边单独显示它们.

我对jquery知之甚少; 我不知道如何实现这一目标.你能告诉我吗？

谢谢 :)

<script>
  $(document).ready(function() { 
    // validate signup form on keyup and submit 
    var validator = $("#signupform").validate({
      rules: {
  customerid: "required",
  date: "required",
  invoiceid: {
    required: true,
    minlength: 2,
    remote: "<? echo base_url();?>mycontroller/function" }
  },
      messages: {
    customerid: "Enter your customerid",
    date: "Enter your date",
    invoiceid: {
       required: "Enter a invoiceid",
       minlength: jQuery.format("Enter at least {0} characters"),
       remote: jQuery.format("{0} is already in use")
    },
      }
    });
  });
</script>

我的表格

<label>Invoice #</label>
<input type="text" name="invoiceid" id="invoiceid" value="" />

<label  style="margin-left:20px;">Date</label>
<input type="text" id="datepicker1" name="date" value=""  />

<label  style="margin-left:20px;">Customer</label>
<input type="text" id="customerid" name="customerid" value=""  />

我会用这个showErrors选项来完成这个:

showErrors: function(errorMap, errorList) {
    $(".errormsg").html($.map(errorList, function (el) {
        return el.message;
    }).join(", "));
},

示例: http ://jsfiddle.net/bd3zM/

笔记:

• 用于$.map根据errorList传递给函数的参数构建错误消息数组.
• 然后用于.join(", ")将上面的数组连接成一个字符串.
• 放置内部元件(一个或多个)与类内容errormsg使用html.
