Sharing of code examples using JS and jquery to implement time difference display effects such as minutes ago, hours ago, and days ago_javascript skills

To achieve similar functions, you can use JS. The implementation method is as follows:

1. JavaScript function implementation:
Example 1:

Copy code The code is as follows:

//JavaScript function:
var minute = 1000 * 60;
var hour = minute * 60;
var day = hour * 24;
var halfamonth = day * 15;
var month = day * 30;
function getDateDiff(dateTimeStamp){
var now = new Date().getTime();
var diffValue = now - dateTimeStamp;
if(diffValue //If the dates do not match, a pop-up window will notify you
//alert("The end date cannot be less than the start date!");
}
var monthC =diffValue/month;
var weekC =diffValue/(7*day);
var dayC =diffValue/day;
var hourC =diffValue/hour;
var minC =diffValue/minute;
if(monthC>= 1){
result="Published in" parseInt(monthC) "months ago";
}
else if(weekC>=1){
result="Published in" parseInt(weekC ) "week ago";
}
else if(dayC>=1){
result="Published in" parseInt(dayC) "day ago";
}
else if( hourC>=1){
result="Posted on" parseInt(hourC) "hours ago";
}
else if(minC>=1){
result="Posted on" parseInt(minC) "minutes ago";
}else
result="Just published";
return result;
}

If the time format you get is not a timestamp, you can use the following JavaScript function to convert the string into a timestamp. The function of this function is equivalent to the JS version of strtotime:

Copy code The code is as follows:

//js function code: convert string to timestamp
function getDateTimeStamp(dateStr){
return Date.parse(dateStr.replace(/-/gi,"/"));
}

Example 2:

Copy code The code is as follows:

<script> >function jsDateDiff(publishTime){                                                                                                                                              d = timeNow - publishTime; <BR> d_days = parseInt(d/86400); d_hours = parseInt(d/3600); d_minutes = parseInt(d/60); days>0 && d_days<4 ){  else if(d_hours<=0 && d_minutes>0){                                                                s.getFullYear() "Year"; <BR> return (s.getMonth() 1) "month" s.getDate() "day"; <BR> } } <BR>} <BR></script>



2. jquery plug-in implementation

HTML code:




Copy code


The code is as follows:


">

Call code:

Copy code The code is as follows:

jQuery("span.timeago ").timeago();

Plug-in source code:

Copy code The code is as follows:

    // AMD. Register as an anonymous module.
