Question

我正在学习如何在Django中使用Ajax GET和POST，我有这个问题，请你抽出时间来帮助我。谢谢！

我遇到的问题是当我点击POST按钮时，它总是转到views.ajax_get（当我希望它应该转到views.ajax_post时）。

这是HTML模板

<button class="get_button" id="get-button" type="button">Get button</button>

<form method="POST">
  {%csrf_token%}
  <button class="post_button" id="post-button" type="submit">Post button</button>
</form>

这是Javascripts：

<script>
  $(document).ready(function() {
    $('.get_button').click(function() {

  $.ajax({
    type: "GET",
    url: "{%url 'myapp:ajax_get' %}",
    success: function(response) {
      alert('Ajax GET')
    }
  });
});

$('.post_button').click(function() {

  $.ajax({
    type: "POST",
    url: "{%url 'myapp:ajax_post' %}",
    success: function(response) {
      alert('Ajax POST');
    }
  });
});

// CSRF code
function getCookie(name) {
  var cookieValue = null;
  var i = 0;
  if (document.cookie && document.cookie !== '') {
    var cookies = document.cookie.split(';');
    for (i; 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);
        }
      }
    });

  });
</script>

您尚未停用表单或按钮的默认操作。因此，Ajax被触发，但随后通过浏览器正常提交表单。
