[英]Javascript Date/Time not Working on iOS Device with Chrome
I am working with date/time in javascript and it is working properly on chrome windows but it is not working within Chrome on iOS devices. 我正在使用javascript中的日期/时间,它在Chrome窗口上正常工作,但它在iOS设备上的Chrome中无效。 The difference between two times is not calculated properly on iOS. 在iOS上无法正确计算两次之间的差异。
Here is my code: 这是我的代码:
var start_timeObj = moment(start_time, ["h:mm A"]);
var end_timeObj = moment(end_time, ["h:mm A"]);
var start_time=start_timeObj.format("HH:mm");
var end_time=end_timeObj.format("HH:mm");
var diff = ( new Date("1970-1-1 " + end_time) - new Date("1970-1-1 " + start_time) ) / 1000 / 60 / 60;
if(diff==1)
{
Have you tried using moment's built in diff functionality? 你尝试过使用moment内置的diff功能吗?
var start = moment(start_time, ["h:mm A"]);
var end = moment(end_time, ["h:mm A"]);
var diffMilliseconds = end.diff(start) // outputs 3600000 (in ms)
var diffHours = diff / 1000 / 60 / 60; // outputs 1
Documentation: https://momentjs.com/docs/#/displaying/difference/ 文档: https : //momentjs.com/docs/#/displaying/difference/
If you don't want to use moment you could try using: 如果您不想使用片刻,可以尝试使用:
var date1 = new Date('1998-07-20');
var date2 = new Date('1998-07-23');
var diffTime = Math.abs(date2.getTime() - date1.getTime());
diffDays = Math.ceil(diffTime / (1000 * 60 * 60 * 24)) + 1;
If you don't add 1
to diffDays the end date won't be included. 如果不向diffDays添加1
,则不包括结束日期。
You can do exactly the same using a H:m:s format ( https://playcode.io/396986?tabs=script.js,preview,console ) 您可以使用H:m:s格式完成相同的操作( https://playcode.io/396986?tabs=script.js,preview,console )
