AJAX无法使用Django App

mysite / urls.py ：

from mysite import views url(r'^checkhandles/$', views.checkhandles, name='checkhandles'), 

mysite / views.py ：

 def checkhandles(request, email): if request.is_ajax(): message = 'Yes, I am reachable!' else: message = 'No, I am not reachable!' return HttpResponse(message) 

mysite-ajax.js ：关于DOM-ready。

 $(document).on('blur', '#email', function(){ var $this = $( this ); var email = $this.val(); if (validateEmail(email) === true){ alert(email); var request = $.ajax({ url: "/mysite/checkhandles/", type: "POST", data: { email : email }, dataType: "json" }); request.done(function( msg ) { alert( msg ); //$(".email_details").html( msg ); //$(".email_etails").slideDown(150); }); }; }) 

我怎么做这个？ 它只能alert(email)和alert(msg)可以告诉它可以告诉AJAX成功不起作用。

这是一个CSRF令牌问题。 你发送csrftoken cookie吗？ 去那里https://docs.djangoproject.com/en/dev/ref/contrib/csrf/#csrf-ajax ，了解附加的内容，并从Django网站复制/粘贴这个javascript代码：

 // 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({ beforeSend: function(xhr, settings) { if (!csrfSafeMethod(settings.type) && !this.crossDomain) { xhr.setRequestHeader("X-CSRFToken", csrftoken); } } });
