这里我们使用flask框架,简单实用
目录结构:
upandown/
static/
css/
js/
jquery.min.js
toastr.min.js
templates/
index.html
test.py
首先我们需要一个页面在templates/index.html(这里使用form表单实现)
Document
function checkstatus(){
if('{{status}}'== 'OK'){
toastr['success']("上传成功");
}else if('{{status}}'== 'null'){
toastr['error']("上传失败");
}
}
function get_list(){
$.ajax({
url:'/getlist',
type:'GET',
success:function(result){
len_result = result.length;
for(var x =0; x < len_result; x++){
$("#filelist").append('' + result[x] +'');
}
alert(content_list);
},
error:function(){
alert("失败");
}
});
}
checkstatus();
get_list();
然后是后台接收
