javascript 判断用户有没有操作页面

1. window.onload = function (){
3. (function($){
4. funObj = {
5. timeUserFun:'timeUserFun',
6. }
7. $[funObj.timeUserFun] = function(time){
8. var time = time || 2;
9. var userTime = time*60;
10. var objTime = {
11. init:0,
12. time:function(){
13. objTime.init += 1;
14. if(objTime.init == userTime){
15. console.log(111) // 用户到达未操作事件 做一些处理
16. alert("用户长时间没有操作页面,即将跳转到登录页面");
17. }
18. },
19. eventFun:function(){
20. clearInterval(testUser);
21. objTime.init = 0;
22. testUser = setInterval(objTime.time,1000);
23. }
24. }
26. var testUser = setInterval(objTime.time,1000);
28. var body = document.querySelector('html');
29. body.addEventListener("click",objTime.eventFun);
30. body.addEventListener("keydown",objTime.eventFun);
31. body.addEventListener("mousemove",objTime.eventFun);
32. body.addEventListener("mousewheel",objTime.eventFun);
33. }
34. })(window)
37. // 直接调用 参数代表分钟数,可以有一位小数;
38. timeUserFun(0.1);
39. }
