This function is enabledCurrent TimeAndSite creation timeAfter calculating the difference, the website running time is calculated as N years, N days, n minutes, n seconds. After the code is written, the browser is tested to display the results. It is found that non-IE browser kernels are normally displayed, when the results are displayed in IE browser, they are displayed as follows: undefined: seconds

After troubleshooting, it is found that new date ("15:16:16") in ie11 returns undefined.

Solve the problem

Method 1: Custom Method

Customize a newdate method:

function NewDate(str){    if(!str){      return 0;    }    arr=str.split(" ");    d=arr[0].split("-");    t=arr[1].split(":");    var date = new Date();     date.setUTCFullYear(d[0], d[1] - 1, d[2]);     date.setUTCHours(t[0], t[1], t[2], 0);     return date;  }  

 

Method 2: Use the date. parse () method

'15:16:16 'cannot be used by browsers to correctly generate date objects using new date (STR. The correct usage is '15:16:16 '.

The date string in '/' format is widely supported by various browsers. The date string connected by '-' can only work in chrome.

var timestart = new Date(Date.parse(‘2017-09-01 15:16:16‘.replace(/-/g,"/")))
