前言
最近因为工作中遇到一个需求,需要做了一个批量导入功能,但长时间运行没个反馈状态,很容易让人看了心急,产生各种臆想!为了解决心里障碍,写了这么个功能。
通过线程执行导入,并把正在执行的状态存入session,既共享执行状态,通过ajax调用session里的执行状态,从而实现反馈导入状态的功能!
上代码: 前端页面
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>批量导入数据</title> <style type="text/css"> .pop_body_con { width: 310px; position: fixed; top: 50%; left: 50%; margin-left: -150px; background: #eee; display:none; } .pop_body_con .pop_head { width: auto; padding: 10px 0; background: #fff; } .pop_body_con .pop_head a { display: block; color: #717274; font-size: 12px; text-decoration: none; text-align: center; } .pop_box { width: auto; overflow: hidden; padding: 45px 10px; } .pop_box .pop_text { float: left; } .pop_box .pop_text p { padding: 0; margin: 0; font-size: 12px; line-height: 18px; color: #717274;} .pop_box .progress_bar_con { float: left; width: 220px; position: relative; z-index: 2; } .pop_box .progress_bar_con p { margin: 0; padding: 0; font-size: 12px; color: #fff; line-height: 18px; width: 100%; text-align: center; position: absolute; left: 0; top: 0; z-index: 4; } .pop_box .progress_bar_con .progress_bar_start { width: 100%; height: 18px; background: #C4C0C0; } .pop_box .progress_bar_con .progress_bar_end { width: 16%; height: 18px; background: #2bd35d; position: absolute; left: 0; top: 0; z-index: 3; } .pop_box .progress_bar_con { float: left; } #loading-mask { width: 100%; height: 100%; position: fixed; top: 0px; left: 0px; z-index: 0; background-color: rgba(0, 0, 0, 0.34902); display: none; } </style> <script src="/UploadFiles/2021-04-02/jquery.js">后台页面:
