我正在尝试为我的 Django 表单实现 AJAX 表单提交。
这些文件是在没有 AJAX 的情况下提交的,因此服务器端的逻辑似乎正在运行。并且使用 ajax,除了文件之外的其余值都会被提交。
这是我正在实现的代码,
AJAX 表单提交
(function() {
  // using jQuery
  function getCookie(name) {
    var cookieValue = null;
    if (document.cookie && document.cookie != '') {
      var cookies = document.cookie.split(';');
      for (var i = 0; i < cookies.length; i++) {
        var cookie = jQuery.trim(cookies[i]);
        // Does this cookie string begin with the name we want?
        if (cookie.substring(0, name.length + 1) == (name + '=')) {
          cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
          break;
        }
      }
    }
    return cookieValue;
  }
  var csrftoken = getCookie('csrftoken');
  function csrfSafeMethod(method) {
    // these HTTP methods do not require CSRF protection
    return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
  }
  $.ajaxSetup({
    crossDomain: false, // obviates need for sameOrigin test
    beforeSend: function(xhr, settings) {
    if (!csrfSafeMethod(settings.type)) {
      xhr.setRequestHeader("X-CSRFToken", csrftoken);
    }
  }
  });
})();
jQuery
$('#save-form').live('submit', function(event) { // catch the form's submit event
  event.preventDefault();
  $.ajax({ // create an AJAX call...
      data: $(this).serialize(), // get the form data
      type: $(this).attr('method'), // GET or POST
      url: '/save/', // the file to call
      success: function(response) { // on success..
          $('#modalsave-form').html(response); // update the DIV
      }
  });
  return false;
});
HTML 表单

    <div class="control-group">

    <hr>
    <input class="btn btn-primary pull-right" type="submit" value="Post!" />
    <br>
    {% csrf_token %}
