在表单中结合 Validation (js)、submit (php) 和 modal (bootstrap)

Question

我正在使用 Bootstrap 创建一个简单的联系表单，并希望在按下“提交”按钮时实现以下目标：

• 使用 jQuery 验证表单字段
• 如果验证通过，则使用 PHP 作为处理器提交表单
• 在 Bootstrap 模式对话框中显示一条消息，说明表单已通过电子邮件发送

知道我的 PHP 和 JS 知识低于平均水平，我很高兴地说我已经能够使所有项目单独工作，但我无法将它们组合在一起......

你能给我一些意见吗？

验证用途：

var validator = $("#contact").validate({
  ...

PHP 使用：

mail()

当使用这样的按钮提交表单时，两者都可以工作：

<button type="submit" name="submit" id="submitButton" class="btn btn-bcome pull-right">Send</button>

为了激活对话框，我将按钮更改为：

<button href="#submit" role="button" button type="submit" name="submit" id="submitButton" class="btn btn-bcome pull-right" data-toggle="modal">Send</button>

这会使模态正确显示，但不会发生验证和提交。

我找到了一个相关的帖子： jQuery Modal that appears on form submit。 但我不知道要专门针对我的情况进行调整。

我已经尝试适应你告诉我的内容，这就是我得到的： html部分：

button href="#submit" role="button" button type="submit" name="submit" id="submitButton" class="btn btn-bcome pull-right" data-toggle="modal">Envoyer</button>

和

<div id="submit" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
        <h3 id="myModalLabel">Thanks for your mail</h3>
      </div>
      <div class="modal-body">
        <p>We will get back to you soon</p>
      </div>
      <div class="modal-footer">
        <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
      </div>
    </div>

在我的 JS 文件中：

var $validator = {};

$(document).ready(function()
{
    // validate signup form on keyup and submit
    var validator = $("#contact").validate({
       submitHandler: function(form)
        {
            //code to submit your form here
            //code to open your modal here
        errorClass:'error',
        validClass:'success',
        errorElement:'span',
        highlight: function (element, errorClass, validClass) { 
            $(element).parents("div[class='clearfix']").addClass(errorClass).removeClass(validClass);
        }, 
        unhighlight: function (element, errorClass, validClass) { 
            $(element).parents(".error").removeClass(errorClass).addClass(validClass); 
        },
        rules: {
            fname: {
                required: true,
                minlength: 2
            },
            name: {
                required: true,
                minlength: 2
            },
            email: {
                required: true,
                email: true
            },
            message: {
                required: true,
                minlength: 10
            }
        },
        messages: {
            fname: {
                required: '<span class="help-inline">First name.</span>',
                minlength: jQuery.format('<span class="help-inline">2 chars</span>')
            },
            name: {
                required: '<span class="help-inline">Name.</span>',
                minlength: jQuery.format('<span class="help-inline">2 chars</span>')
            },
            email: {
                required: '<span class="help-inline">Email.</span>',
                email: '<span class="help-inline">Ex : name@exemple.com</span>'
            },
            message: {
                required: '<span class="help-block">Message</span>',
                minlength: jQuery.format('<span class="help-block">10 chars</span>')

        $('form').submit(function() {
            if ($validator.numberOfInvalids() > 0) {
                $('#submit').modal('hide');
            } else {
                $('#submit').modal('show');
            }
        }
    });
}
);

我肯定遗漏了一些东西，但目前只执行模式部分，而不是验证部分或提交表单部分。

知道我应该怎么做才能完成这项工作吗？

如果您使用的是 bassastance 的 jquery 验证插件，您正在寻找 submitHandler 选项，它在此处定义：http://docs.jquery.com/Plugins/Validation/validate#toptions

$(document).ready(function()
    {
        // validate signup form on keyup and submit
        var validator = $("#contact").validate({
           submitHandler: function(form)
            {
                //code to submit your form here
                //code to open your modal here
            }
        });
    }
);

更新：我正在根据 Fred 提供的进一步代码更新此答案。

Javascript：

var $validator; //declared for further use later

$(document).ready(function()
{
    // validate signup form on keyup and submit
    $validator = $("#contact").validate({
        errorClass:'error',
        validClass:'success',
        errorElement:'span',
        highlight: function (element, errorClass, validClass) { 
            $(element).parents("div[class='clearfix']").addClass(errorClass).removeClass(validClass);
        }, 
        unhighlight: function (element, errorClass, validClass) { 
            $(element).parents(".error").removeClass(errorClass).addClass(validClass); 
        },
        rules: {
            fname: {
                required: true,
                minlength: 2
            },
            name: {
                required: true,
                minlength: 2
            },
            email: {
                required: true,
                email: true
            },
            message: {
                required: true,
                minlength: 10
            }
        },
        messages: {
            fname: {
                required: '<span class="help-inline">First name.</span>',
                minlength: jQuery.format('<span class="help-inline">2 chars</span>')
            },
            name: {
                required: '<span class="help-inline">Name.</span>',
                minlength: jQuery.format('<span class="help-inline">2 chars</span>')
            },
            email: {
                required: '<span class="help-inline">Email.</span>',
                email: '<span class="help-inline">Ex : name@exemple.com</span>'
            },
            message: {
                required: '<span class="help-block">Message</span>',
                minlength: jQuery.format('<span class="help-block">10 chars</span>')
            }
        },
        submitHandler: function(form) //submitHandler is an option taken by the validate function
        {
            //i put your submission code in here

            $('form').submit(function() {
                if ($validator.numberOfInvalids() > 0) 
                {
                    $('#submit').modal('hide');
                } else 
                {
                    $('#submit').modal('show');
                }
            });
        }
    });
});
