基本操作:
1在项目s13day18_django的settings配置中，指定jquery的目录，同时注释掉CSRF
STATIC_URL = '/static/' STATICFILES_DIRS = ( os.path.join(BASE_DIR,'static'), ) # 'django.middleware.csrf.CsrfViewMiddleware',
2在app01下面，指定路由关系
urlpatterns = [ # url(r'^index/(d+)/', views.index), # url(r'^detail/(d+)/',views.detail), # url(r'^template/',views.template), url(r'^extend/',views.extend), url(r'^assets/',views.assets), url(r'^userinfo/',views.userinfo), url(r'^ajax_demo/',views.ajax_demo), ]
3在app01下面，定义ajax_demo函数
def ajax_demo(request): if request.method == 'POST': user = request.POST.get('user') pwd = request.POST.get('pwd') print(user,pwd) if user == '111' and pwd == '222': return HttpResponse('1') else: return HttpResponse('2') return render(request,'ajax_demo.html')
4 在templates中，添加关于ajax_demo的HTML信息
<body>
<div>
<p>用户名: <input type="text" id="username" /></p>
</div>
<div>
<p>密码: <input type="password" id="pwd" /></p>
</div>
<input type="button" value="提交" onclick="SubmitForm();"/>
<script src="/static/jquery-1.12.4.js"></script>
<script>
function SubmitForm(){
$.ajax({
url:'/web/ajax_demo/',
type:'POST',
data:{'user':$('#username').val(),'pwd':$('#pwd').val()},
success:function(data){
if(data == '1'){
location.href="http://www.baidu.com";
}
else{
alert("用户名或密码错误")
}
}
})
}
</script>
</body>
过程流程:整个执行的过程是，ajax传递参数给了函数ajax_demo，函数获取到用户键入的值，然后通过HttpResponse返回给回调函数success，回调函数再执行相应的操作。
二 但是在实际的使用中，我们要这么定义views.py
import json def ajax_demo(request): if request.method == 'POST': ret = {'status':False,'message':''} user = request.POST.get('user') pwd = request.POST.get('pwd') print(user,pwd) if user == '111' and pwd == '222': ret['status'] = True return HttpResponse(json.dumps(ret)) else: ret['message'] = '用户名或密码错误' return HttpResponse(json.dumps(ret)) return render(request,'ajax_demo.html')
ajax_demo.html
<body>
<div>
<p>用户名: <input type="text" id="username" /></p>
</div>
<div>
<p>密码: <input type="password" id="pwd" /></p>
</div>
<input type="button" value="提交" onclick="SubmitForm();"/>
<script src="/static/jquery-1.12.4.js"></script>
<script>
function SubmitForm(){
$.ajax({
url:'/web/ajax_demo/',
type:'POST',
data:{'user':$('#username').val(),'pwd':$('#pwd').val()},
dataType:'json',
success:function(data){
if(data.status){
location.href="http://www.baidu.com";
}
else{
alert(data.message)
}
}
})
}
</script>
</body>
