确认表格&如果表单对JQuery有效,则显示消息

标签: javascript jquery forms

我正在开发我的Django应用程序,我想使用JavaScript来改进我的网站。

我有一张表格,我想展示两件事:

  • 提交前确认表单
  • 如果表单已提交,请显示消息:“表单已保存”

这是我第一次使用JS,我需要帮助来完成这个过程。

这是我的代码:

    <form class = "form" method='POST' action=''> {% csrf_token %}
        <br></br>
        {{ form.as_p}}
        <br></br>

        <button type="submit">Valider</button>
    </form>

    <script>
        $('#form').submit(function() {
        var c = confirm("Click OK to continue?");
        return c; //you can just return c because it will be true or false
    });
    </script>

如果我的表格有效并保存:

<script type="text/javascript" >
                $(document).on('Valider', 'form.form', function(form) {
                var $form = $(form);
                $.ajax({
                    url:"/path_to_my_html_file/BC_form2.html",
                    type: "POST",
                    success: function(form) {
                    alert("Form is saved");
                    }
                });
                });
            </script>

你能帮帮我吗?

谢谢

您可以尝试使用此代码:

&#13;
&#13;
$('#form').submit(function(e) {
    // Prevents form to be submitted by default post request with page reloading
    e.preventDefault();
    if (confirm("Click OK to continue?")) {
      // Here you can call your AJAX request
      callAjax($('input[type=text]').val())
    }
});

function callAjax(value) {
  // Making AJAX request to your endpoint
  // GET ipify just for example
  $.ajax({
      url:"https://api.ipify.org?format=json",
      type: "GET",
      success: function(form) {
        alert("Form is saved");
      }
  });
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
 <form id="form"> 
    <input type="hidden" value="MOCK FOR CSRF TOKEN" />
    <br></br>
    <input type="text" required />
    <br></br>

    <button type="submit">Valider</button>
</form>

在提交功能中使用.valid()

$('#form').submit(function() {
  var isValid=$("#form").valid();
           if (isValid) { //If there is no validation error

            var c = confirm("Click OK to continue?");
            if(c){
              $.ajax({
                url:"/path_to_my_html_file/BC_form2.html",
                type: "POST",
                success: function(form) {
                  alert("Form is saved");
                }
              });

            }

          } 
          else {
            alert('form is not valid');                               
          }

        });
</script>
