Question

在我的代码中，我有一个表单

 <form id="form_enquiry" name="enquiry-form">
        <ul>
            <li>
                <label>Name</label>
                <input name="name" type="text" id="name" class="required"/>
            </li>
            <li>
                <label>Email</label>
                <input name="email" type="text" id="email" class="required"/>
            </li>
            <li>
                <label>Telephone</label>
                <input name="telephone" type="text" id="telephone" class="required"/>
            </li>
            <li>
                <label>Message</label>
                <textarea rows="4" name="message" id="message" class="required"></textarea>
            </li>
             <li>
                <label>How did you hear about us?</label>
                <div class="select-arrow">
                <select name="select_option" id="select_option" class="required">
                    <option value="" selected="selected">— — —</option>
                    <option value="I am a repeat customer">I am a repeat customer</option>
                    <option value="You where recommended to me">You where recommended to me</option>
                    <option value="Google Search">Google Search</option>
                    <option value="Travelzoo">Travelzoo</option>
                    <option value="Newspaper article">Newspaper article</option>
                    <option value="Facebook">Facebook</option>
                </select>
                </div>
            </li>
             <li>
                <button type="submit" id="enquiry_submit">Send</button>
            </li>
          </ul>
        </form>

这个表单我使用jquery代码提交

$("#form_enquiry").submit(function (e) {
        e.preventDefault(); // this will prevent from submitting the form.
          //alert('check');
            $("#form_enquiry").validate({
             submitHandler: function(form) {

                var name1 = $('#name').val();
                var email1 = $('#email').val();
                var telephone1 = $('#telephone').val();
                var message1 = $('#message').val();
                var select_option1 = $('#select_option').val();
                var site_url = <?= $_SERVER['REQUEST_URI'] ?>;
                    if(name1 && email1 && telephone1 && message1 && select_option1) 
                    {
                        $.ajax({
                            type: 'post',
                            url: '<?= base_url()?>'+'frontend/form_enquiry',
                            data: 'name='+name1+'&email='+email1+'&telephone='+telephone1+'&message='+message1+'&select_option='+select_option1+'&site_url='+site_url
                            //success: function(data) { $('#login_err').html('Success ...'); }
                        });
                    }
                }

            });
        });

工作正常但需要点击两次发送按钮.. 我希望只需单击一下即可提交表单，但代码中有错误帮我...

如果您正在使用jQuery validate，则不必手动绑定提交事件，因为它会为您执行此操作。只需单独使用它：

$("#form_enquiry").validate({
    submitHandler: function (form) {

        var name1 = $('#name').val();
        var email1 = $('#email').val();
        var telephone1 = $('#telephone').val();
        var message1 = $('#message').val();
        var select_option1 = $('#select_option').val();
        var site_url = <?= $_SERVER['REQUEST_URI'] ?> ;
        if (name1 && email1 && telephone1 && message1 && select_option1) {
            $.ajax({
                type: 'post',
                url: '<?= base_url()?>' + 'frontend/form_enquiry',
                data: 'name=' + name1 + '&email=' + email1 + '&telephone=' + telephone1 + '&message=' + message1 + '&select_option=' + select_option1 + '&site_url=' + site_url
                //success: function(data) { $('#login_err').html('Success ...'); }
            });
        }
    }

});

使用带有序列化表单数据的ajax。因此无需从输入字段逐个获取值。

$("#form_enquiry").submit(function(e) {
      e.preventDefault();
      $.ajax({
      'type': 'POST',
      'url': '<?= base_url()?>'+'frontend/form_enquiry',
       'data': $("#form_enquiry").serialize(),
       success: function(data) {                           
       }});

});
