篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了django + jQuery AJAX POST数据相关的知识，希望对你有一定的参考价值。
废话少说，直接代码伺候：
views：
from django.http import JsonResponse def test_post(request): name = request.POST[‘name‘] city = request.POST[‘city‘] qq = request.POST[‘qq‘] dict = {‘name‘:name,‘city‘:city,‘qq‘:qq} return JsonResponse(dict) def test(request): return render(request,‘app/accounts/test.html‘)
urls：
urlpatterns = [ url(r‘^test/$‘,views.test), url(r‘^test/post$‘,views.test_post,name=‘test_post‘), ]
test.html
{% load staticfiles %}
<!DOCTYPE html>
<html lang="zh-CN">
<head>
<meta charset="UTF-8">
<title>testajax</title>
</head>
<body>
<div id="test"><h2>请点击下面的按钮，通过jQuery AJAX接收数据</h2></div>
<div id="result"></div>
<button id="btn1" type="button">获取服务器数据</button>
<script src="{% static ‘jquery/jquery-2.2.0.min.js‘ %}"></script>
<script src ="{% static ‘js/csrf.js‘ %}"></script>
<script>
$().ready(function(){
$(‘#btn1‘).click(function(){
$.post("{% url ‘test_post‘ %}",
{
csrfmiddlewaretoken:"{{ csrf_token }}",
name:"dodo",
city:"Ganzhou",
qq:"12519460"
},
function (data,status) {
$.each(data,function(key,value){
$("#result").append(status +":"+key +":"+value +"<br/>")
})
}
)
})
})
</script>
</body>
</html>
关于POST数据：csrf_token报错问题，参照自强学堂http://www.ziqiangxuetang.com/django/django-csrf.html。同时把js/csrf.js代码如下：
/** * Created by dodo on 2016/1/29. */ jQuery(document).ajaxSend(function(event, xhr, settings) { function getCookie(name) { var cookieValue = null; if (document.cookie && document.cookie != ‘‘) { var cookies = document.cookie.split(‘;‘); for (var i = 0; i < cookies.length; i++) { var cookie = jQuery.trim(cookies[i]); // Does this cookie string begin with the name we want? if (cookie.substring(0, name.length + 1) == (name + ‘=‘)) { cookieValue = decodeURIComponent(cookie.substring(name.length + 1)); break; } } } return cookieValue; } function sameOrigin(url) { // url could be relative or scheme relative or absolute var host = document.location.host; // host + port var protocol = document.location.protocol; var sr_origin = ‘//‘ + host; var origin = protocol + sr_origin; // Allow absolute or scheme relative URLs to same origin return (url == origin || url.slice(0, origin.length + 1) == origin + ‘/‘) || (url == sr_origin || url.slice(0, sr_origin.length + 1) == sr_origin + ‘/‘) || // or any other URL that isn‘t scheme relative or absolute i.e relative. !(/^(\/\/|http:|https:).*/.test(url)); } function safeMethod(method) { return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method)); } if (!safeMethod(settings.type) && sameOrigin(settings.url)) { xhr.setRequestHeader("X-CSRFToken", getCookie(‘csrftoken‘)); } });
