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。我尝试验证<input name=first>和<input name=second>以将错误消息输出到：

<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。

如何将错误消息放在<span>？

中

$(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

您应该使用的是errorLabelContainer

＆＃13;

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

＆＃13;

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

＆＃13;

<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>

＆＃13;

如果你想保留你的结构，那么

＆＃13;

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);
      }
    }
  });
});

＆＃13;

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

＆＃13;

<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>

＆＃13;

Answer 2

您可以简单地创建与同一功能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！

Answer 3

 if (e.attr("name") == "firstName" ) {
     $("#firstName__validate").text($(error).text());
     console.log($(error).html());
 }

尝试此获取错误对象的文本

Answer 4

在您的validate方法中添加以下代码：

 errorLabelContainer: '#errors'

，然后在您的html中，将其简单地放在要捕获错误的位置：

<div id="errors"></div>

所有错误都将保留在div中，与您的输入框无关。

对我来说很好。

HTML

<form ... id ="GoogleMapsApiKeyForm">
    ...
    <input name="GoogleMapsAPIKey" type="text" class="form-control" placeholder="Enter Google maps API key" />
    ....
    <span class="text-danger" id="GoogleMapsAPIKey-errorMsg"></span>'
    ...
    <button type="submit" class="btn btn-primary">Save</button>
</form>

JavaScript

$(function () {
    $("#GoogleMapsApiKeyForm").validate({
      rules: {
          GoogleMapsAPIKey: {
              required: true
          }
        },
        messages: {
            GoogleMapsAPIKey: 'Google maps api key is required',
        },
        errorPlacement: function (error, element) {

        submitHandler: function (form) {
           // form.submit(); //if you need Ajax submit follow for rest of code below
        }

    //If you want to use ajax
    $("#GoogleMapsApiKeyForm").submit(function (e) {
        e.preventDefault();
        if (!$("#GoogleMapsApiKeyForm").valid())
            return;

       //Put your ajax call here
    });
});

这对我有用

实际上error是一个数组，其中包含错误消息和我们传递的元素的其他值，您可以console.log（error）;看看。如果条件为“ error.appendTo（$（element）.parents（'div'）。find（$（'。errorEmail'）））;“；就是在代码中找到html元素并传递错误消息。

    $("form[name='contactUs']").validate({
rules: {
    message: 'required',
    name: "required",
    phone_number: {
        required: true,
        minlength: 10,
        maxlength: 10,
        number: false
    },
    email: {
        required: true,
        email: true
    }
},
messages: {
    name: "Please enter your name",
    email: "Please enter a valid email address",
    message: "Please enter your message",
    phone_number: "Please enter a valid mobile number"
},
errorPlacement: function(error, element) {
        $("#errorText").empty();

        if(error[0].htmlFor == 'name')
        {
            error.appendTo($(element).parents('div').find($('.errorName')));
        }
        if(error[0].htmlFor == 'email')
        {
            error.appendTo($(element).parents('div').find($('.errorEmail')));
        }
        if(error[0].htmlFor == 'phone_number')
        {
            error.appendTo($(element).parents('div').find($('.errorMobile')));
        }
        if(error[0].htmlFor == 'message')
        {
            error.appendTo($(element).parents('div').find($('.errorMessage')));
        }
      }
    });
