Django（十三）ajax 与 Bootstrap,font-awesome
prop，attr,val
font-awesome：字体，图标库
对话框添加，删除，修改：
添加：
Ajax偷偷向后台发请求：
1. 下载引入jQuery
2.
$.ajax({
url: '/add_classes.html',
type: 'POST',
data: {'username':'root','password': ''},
success:function(arg){
// 回调函数，arg是服务端返回的数据
}
})

"""ajax_learn URL Configuration The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/2.1/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: path('', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))

urls
总结：
1.
Python序列化
字符串 = json.dumps(对象) 对象->字符串
对象 = json.loads(字符串) 字符串->对象 JavaScript:
字符串 = JSON.stringify(对象) 对象->字符串
对象 = JSON.parse(字符串) 字符串->对象 应用场景：
数据传输时，
发送：字符串
接收：字符串 -> 对象
2. ajax $.ajax({
url: 'http//www.baidu.com',
type: 'GET',
data: {'k1':'v1'},
success:function(arg){
// arg是字符串类型
// var obj = JSON.parse(arg)
}
}) $.ajax({
url: 'http//www.baidu.com',
type: 'GET',
data: {'k1':'v1'},
dataType: 'JSON',
success:function(arg){
// arg是对象
}
}) $.ajax({
url: 'http//www.baidu.com',
type: 'GET',
data: {'k1':[1,2,3,4]},
dataType: 'JSON',
success:function(arg){
// arg是对象
}
}) 发送数据时：
data中的v a. 只是字符串或数字
$.ajax({
url: 'http//www.baidu.com',
type: 'GET',
data: {'k1':'v1'},
dataType: 'JSON',
success:function(arg){
// arg是对象
}
})
b. 包含属组
$.ajax({
url: 'http//www.baidu.com',
type: 'GET',
data: {'k1':[1,2,3,4]},
dataType: 'JSON',
traditional: true,
success:function(arg){
// arg是对象
}
}) c. 传字典 b. 包含属组
$.ajax({
url: 'http//www.baidu.com',
type: 'GET',
data: {'k1': JSON.stringify({}) },
dataType: 'JSON',
success:function(arg){
// arg是对象
}
}) 3. 事件委托 $('要绑定标签的上级标签').on('click','要绑定的标签',function(){}) $('要绑定标签的上级标签').delegate('要绑定的标签','click',function(){}) 4. 编辑 5. 总结 新URL方式：
- 独立的页面
- 数据量大或条目多 对话框方式：
- 数据量小或条目少
-增加，编辑
- Ajax: 考虑，当前页；td中自定义属性
- 页面（***） 删除：
对话框
jQuery ajax()使用serialize()提交form数据
- 对话框
- var data = $('#fmForm表单的ID').serialize();
$.ajax({
data: $('#fm').serialize()
})
<form action="">
First name: <input type="text" name="FirstName" value="Bill" /><br />
Last name: <input type="text" name="LastName" value="Gates" /><br />
</form>
$(document).ready(function(){
console.log($("form").serialize()); // FirstName=Bill&LastName=Gates
});
这样，我们就可以把序列化的值传给ajax()作为url的参数，轻松使用ajax()提交form表单了，而不需要一个一个获取表单中的值然后传给ajax()，
使用$.post()、$.get()和$.getJSON()也是一样的：
$.post('your url', $("form").serialize(), function(data) {
// your code
}
});
$.get('your url', $("form").serialize(), function(data) {
// your code
}
});
$.getJSON('your url', $("form").serialize(), function(data) {
// your code
}
});
