【问题描述】：

当我的图标在 input-lg 内部时，当我单击该字段时，它看起来像......我的意思是我的评论应该在这里，但它不应该使图标变大。我需要评论会来，但图标和输入 lg 字段。

这是我的演示代码：

$(document).ready(function () {
    $('#contact-form').validate({
        rules: {
            fullname: {
                minlength: 4,
                required: true
            },
            username: {
                required: true,
                email: true
            },
            password: {
                minlength: 8,
                required: true
            },
            confirm_password: {
                minlength: 8,
                required: true
            },
            mobile: {
                minlength: 11,
                required: true
            }
        },
        highlight: function (element) {
            $(element).closest('.control-group').removeClass('success').addClass('error');
        },
        success: function (element) {
            element.text('OK!').addClass('valid')
                .closest('.control-group').removeClass('error').addClass('success');
        }
    });
});

            </div>
        </div>
        <p class="help-block"></p>

    </form>
</div>

我需要这样的：

【问题讨论】：

标签： javascript jquery twitter-bootstrap validation input-field

【解决方案1】：

使用errorPlacement 和insertAfter。

$('#contact-form').validate({        
   errorPlacement: function(error, element) {
       error.insertAfter(element.parent());
   }
});

FIDDLE

此外，自定义消息可以这样完成：-

$('#contact-form').validate({
     rules: {
         fullname: {
             minlength: 4,
             required: true
         }
     },
     messages: {
         fullname:{
              required: "Required input",
              minlength: jQuery.validator.format("Too short: Minimum of {0} characters")
         }
     }
});
