即使存在验证错误，表单也会提交。出现验证错误时如何禁用提交按钮？这是 .js 文件

,submitFu:function(){
_.validateFu(_.labels)                          
if(!_.form.has('.'+_.invalidCl).length)
    $.ajax({
        type: "POST",
        url:_.mailHandlerURL,
        data:{
            name:_.getValFromLabel($('.name',_.form)),
            email:_.getValFromLabel($('.email',_.form)),
            phone:_.getValFromLabel($('.phone',_.form)),
            //fax:_.getValFromLabel($('.fax',_.form)),
            //state:_.getValFromLabel($('.state',_.form)),
            message:_.getValFromLabel($('.message',_.form)),
            owner_email:_.ownerEmail,
            stripHTML:_.stripHTML
        },
        success: function(){
            _.showFu()
        }
    })          
},
showFu:function(){
_.success.slideDown(function(){
    setTimeout(function(){
        _.success.slideUp()
        _.form.trigger('reset')
    },_.successShow)
})
},

这是表格：

    <form id="contact-form" action="contactTq.php" method="post">
                    <div class="success"> Contact form submitted! <strong>We will be in touch soon.</strong></div>
                    <fieldset>
                        <label class="name">
                            <input type="text" name="name" value="Enter Your Name:" >
                            <span class="error">*This is not a valid name.</span>
                            <span class="empty">*This field is required.</span>
                            <span class="clear"></span>
                        </label>
                        <label class="email">
                            <input type="text" name="email" value="Enter Your E-mail:">
                            <span class="error">*This is not a valid email address.</span>
                            <span class="empty">*This field is required.</span>
                            <span class="clear"></span>
                        </label>
                        <label class="phone">
                            <input type="text" name="phone" value="Enter Your Phone (optional):">
                            <span class="error">*This is not a valid phone number.</span>
                            <span class="clear"></span>
                        </label>
                        <label class="message">
                            <textarea name="msg">Enter Your Message:</textarea>
                            <span class="error">*The message is too short.</span>
                            <span class="empty">*This field is required.</span>
                            <span class="clear"></span>
                        </label>
                        <div class="buttons"><strong><a class="button" data-type="reset">Reset<span></span></a></strong><strong><a class="button" data-type="submit" href="javascript:{}" onclick="document.getElementById('contact-form').submit();">Submit<span></span></a></strong></div>
                    </fieldset>
                </form>

Knockout.js 完美地完成了您正在寻找的工作。您可以将现有的 javascript 放入 ViewModel，然后在您的按钮上放置一个数据绑定以启用所有字段是否都有效。您可以在此处查看如何操作：http: //knockoutjs.com/documentation/enable-binding.html

您似乎在单击按钮后立即提交表单，因为 onclick 处理程序编写如下：

onclick="document.getElementById('contact-form').submit();"

只需更改 onclick 处理程序以执行该submitFu功能，这应该可以解决问题。

将提交按钮的 onclick 事件更改为 onclick="return submitFu()"

如果验证失败，则返回 false 并且表单将不会提交。我认为您可以对表单的 onsubmit 事件执行相同的操作。
