Jquery验证自定义错误消息位置

Question

这看起来非常简单,但我无法弄清楚.我正在使用jquery validate插件.我正在尝试验证<input name=first>并将<input name=second>错误消息输出到:

<span id="errNm2"></span> <span id="errNm1"></span>

我已经开始编写errorPlacement:您可以在其中自定义错误消息位置.

如何将错误消息放入其中<span>？

$(document).ready(function () {
    $('#form').validate({
        errorPlacement: function(error, element) {
            error.append($('.errorTxt span'));
        },
        rules,
});

<input type="text" name="first"/>
<input type="text" name="second"/>

<div class="errorTxt">
   <span id="errNm2"></span>
   <span id="errNm1"></span>
</div>

Answer 1

你应该使用的是errorLabelContainer

jQuery(function($) {
  var validator = $('#form').validate({
    rules: {
      first: {
        required: true
      },
      second: {
        required: true
      }
    },
    messages: {},
    errorElement : 'div',
    errorLabelContainer: '.errorTxt'
  });
});

.errorTxt{
  border: 1px solid red;
  min-height: 20px;
}

<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.1.js"></script>
<script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.12.0/jquery.validate.js"></script>
<script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.12.0/additional-methods.js"></script>

<form id="form" method="post" action="">
  <input type="text" name="first" />
  <input type="text" name="second" />
  <div class="errorTxt"></div>
  <input type="submit" class="button" value="Submit" />
</form>

如果你想保留你的结构

jQuery(function($) {
  var validator = $('#form').validate({
    rules: {
      first: {
        required: true
      },
      second: {
        required: true
      }
    },
    messages: {},
    errorPlacement: function(error, element) {
      var placement = $(element).data('error');
      if (placement) {
        $(placement).append(error)
      } else {
        error.insertAfter(element);
      }
    }
  });
});

#errNm1 {
  border: 1px solid red;
}
#errNm2 {
  border: 1px solid green;
}

<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.1.js"></script>
<script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.12.0/jquery.validate.js"></script>
<script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.12.0/additional-methods.js"></script>

<form id="form" method="post" action="">
  <input type="text" name="first" data-error="#errNm1" />
  <input type="text" name="second" data-error="#errNm2" />
  <div class="errorTxt">
    <span id="errNm2"></span>
    <span id="errNm1"></span>
  </div>
  <input type="submit" class="button" value="Submit" />
</form>

您可以简单地创建与同一函数中所需字段匹配的额外条件.例如,使用上面的代码......

$(document).ready(function () {
    $('#form').validate({
        errorPlacement: function(error, element) {
            //Custom position: first name
            if (element.attr("name") == "first" ) {
                $("#errNm1").text(error);
            }
            //Custom position: second name
            else if (element.attr("name") == "second" ) {
                $("#errNm2").text(error);
            }
            // Default position: if no match is met (other fields)
            else {
                 error.append($('.errorTxt span'));
            }
        },
        rules
});

希望有所帮助!
