为什么在填写所有字段之前我的提交按钮会重新启用?

Why does my submit button gets re-enabled before all fields are filled in?

我正在使用下面的代码来验证(通过 bootstrap-validator)我的联系表单中每个字段的内容(还有通过 google recaptcha 进行的额外检查)。您可以在 at this address.

查看和测试表格

默认情况下,提交按钮被禁用 <button id="submit-btn" class="btn-upper btn-yellow btn" name="submit" type="submit" disabled><i class="fa fa-paper-plane-o" aria-hidden="true"></i> SEND</button>,一旦所有字段通过 bootstrap-validator 验证并且 google recaptcha 完成,应该会重新启用。

问题:填写第一个字段后,提交按钮会直接重新启用,因此必须在某处重新激活它(您可以通过键入进行测试在第一个字段中输入你的名字,然后将鼠标放在提交按钮上,你会看到该按钮处于活动状态而不是禁用状态)

知道问题出在哪里以及如何解决吗?

非常感谢

下面是一个伪代码,有点像您共享页面的克隆,具有在多个事件(keyupchangekeypress 时触发的基本验证检查blur)。

  1. 它检查所有字段是否被填充,如果任何一个为空,按钮将不会被启用。
  2. 它检查 输入 字段是否有 最少 2 个字符。
  3. 它检查消息字段是否有消息长度在 20 到 1000 之间

并且以同样的方式,我们可以不断添加自定义验证以满足我们的需求。

required = function(fields) {
  console.clear();
  var valid = true;
  fields.each(function() { // iterate all
    var $this = $(this);
    if ((($this.is(':text') || $this.is('textarea')) && !$this.val())) {
      valid = false;
    }

    if ($this.is(":text") && $this.val().length < 3) {
      console.log('less than 2 characters..');
      valid = false;
    }

    if ($(this).attr('id') == 'your_message' && ($this.val().length < 20 || $this.val().length > 1000)) {
      console.log('aaVotre message doit faire plus de 20 caractères et moins de 1000.');
      valid = false;
    }
  });

  return valid;
}

validateRealTime = function() {
  var fields = $("form :input");
  fields.on('keyup change keypress blur', function() {
    if (required(fields)) {
      {
        $("#register").prop('disabled', false);
      }
    } else {
      {
        $("#register").prop('disabled', true);
      }
    }
  });
}

validateRealTime();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
  First name<br />
  <input type="text" id="user_input" name="firstname" /><br /> Name
  <br />
  <input type="name" id="name_input" name="name" /><br /> Email<br />
  <input type="email" id="email_input" name="email" /><br />
  <br/> Your Message
  <textarea name="your_message" id="your_message"></textarea>
  <br>

  <input type="submit" id="register" value="Submit" disabled="disabled" />

</form>

希望对您有所帮助。编码愉快!

命名提交按钮 submit 似乎有问题 http://bootstrapvalidator.votintsev.ru/getting-started/#name-conflict 可能导致了意外行为

只需将单独的验证写入您的表单

$("#contact_form").on('change', function () {
    $("form").each(function(){
    if ($(this).find(':input').val()== "")
    $('#submit-btn').addClass('disabled');
  });
})

实际上您的代码按预期工作并且没有错误。但在 bootstrapValidator 中,您需要在 success.form.bv 事件之前检查每个字段的状态,如下所述。

请在 .success.form.bv 事件之前添加此事件,如下所述。

.on('status.field.bv', function(e, data) {
    var $this = $(this);
    var formIsValid = true;
    $('.form-group', $this).each(function() {
        formIsValid = formIsValid && $(this).hasClass('has-success');
    });
    $('#submit-btn', $this).attr('disabled', !formIsValid);
}).on('success.form.bv', function(e, data) {

如果不起作用请告诉我。
