Question

我的表单中有这个jQuery验证控件。它正在运作：

$("#webform-client-form-45").submit(function(){

  if($("#edit-submitted-name-surname").val() == "" || $("#edit-submitted-name-surname").val() == "Name Surname"){

        return false;
    }else if($("#edit-submitted-telephone").val() == "" || $("#edit-submitted-telephone").val() == "Telephone"){

        return false;
    }else if($("#edit-submitted-e-posta").val() == "" || $("#edit-submitted-e-posta").val() == "E-MAIL"){

        return false;

    }else{  if($("#edit-submitted-messages").text() == "" || $("#edit-submitted-messages").text() == "Message"){

                return false;
            }else
        return true;
    }
});

但是当用户在此字段中将字段留空或写错时，我想显示警告。例如，“请输入电子邮件地址”“

我该怎么做？

Answer 1

使用提醒框：

if($("#edit-submitted-name-surname").val() == "" || $("#edit-submitted-name-surname").val() == "Name Surname")
{
alert("Please input your name");
return false;
}

使用div：

// HTML

<input type = "text" name = "edit-submitted-name-surname" id = "edit-submitted-name-surname" />
<div class = "error" id = "name_error">Please input your name</div>

// CSS

.error{ display: none; color: red;}

// jquery的

Put this at the top of the function: $('.error').hide();

if($("#edit-submitted-name-surname").val() == "" || $("#edit-submitted-name-surname").val() == "Name Surname")
    {
    $('#name_error').show();
    return false;
    }
