提供基于js与python利用ajax传输json数据的部分示例：
在static文件js目录下:
jquery.js
st_goods.js
HTML页面：
<!DOCTYPE html>
{% load staticfiles %}
<html>
<head>
<meta charset="utf-8">
<title>ECharts</title>
</head>
<body>
<div id="goods_statistics">商品统计</div>
<!-- 为ECharts准备一个具备大小（宽高）的Dom -->
<div id="main" style="height:400px"></div>
<!-- ECharts单文件引入 -->
<script src="http://echarts.baidu.com/build/dist/echarts.js"></script>
<script src="{% static ‘js/jquery.js‘ %}"></script>
<script src="{% static ‘js/st_goods.js‘ %}"></script>
</script>
</body>
</html>JS页面
//商品统计
$("#goods_statistics").click(function(){
$.ajax({
type: ‘get‘,
url: base_url + ‘/statistics/goods_st‘,
data : {},
success: function(e){
result = JSON.parse(e);
goods_st_sort(result.goods_st);
}
})
});
//商品名
var g_name = [];
//关注
var marked = [];
//收藏
var collected = [];
//购买
var purchased = [];
//浏览
var browse = [];
function goods_st_sort(goods_st){
var arr = new Array();
for(var i = 0 ; i < goods_st.length ; i++){
arr = goods_st[i].toString().split(‘,‘);
g_name.push(arr[0]);
//console.log(name[i]);
marked.push(arr[1]);
collected.push(arr[2]);
purchased.push(arr[3]);
browse.push(arr[4]);
}
draw();
//console.log(name.length);
}Python代码
#用户行为分析图
def goods_st_pic(request):
return render(request,website.goods_st_pic,None)
#用户行为数据
def goods_st(request):
#连接数据库
conn = MySQLdb.connect(host=‘120.26.38.125‘,user=‘root‘, passwd=‘passw0rd‘,db=‘jkbrother3‘,charset=‘utf8‘)
sql = "select distinct(g.name), g.marked_count, g.collected_count, g.purchased_count, (select sum(count) from adminer_access_record where mold =‘0‘ and action_id =g.id) browse_count from adminer_goods g, adminer_access_record ar where g.id=ar.action_id"
cur = conn.cursor()
#执行sql
cur.execute(sql)
#列出数据
records = cur.fetchall()
result = []
for row in records:
temp = (row[0],row[1],row[2],row[3],row[4])
result.append(temp)
conf = {‘goods_st‘:result}
#关闭连接
cur.close()
conn.close()
return HttpResponse(json.dumps(conf))
注意带参数传值，字典：
var tdata = {"time":"2015-05-17"};
//商品统计
$("#traffic_statistics").click(function(){
$.ajax({
type: ‘post‘,
url: base_url + ‘/statistics/traffic_st‘,
data : tdata,
success: function(e){
result = JSON.parse(e);
print(result.traffic_st);
}
})
});
#网站流量统计
def traffic_st(request):
time = request.POST["time"]
