Not a bug JS DateTime not get last value of Time and Diff

[truonglv]

As title. When i do update the DateTime element. The DateTime still get the old value.

Because this line:

thisDiff = parseInt($element.data('diff'), 10);
                thisTime = parseInt($element.data('time'), 10);

I think it should be:

thisDiff = parseInt($element.attr('data-diff'), 10);
                thisTime = parseInt($element.attr('data-time'), 10);

Not sure, see here :
.data() | jQuery API Documentation

.data and .attr('data- is the same thing if I am not mistaken...

Just testing. Made new DOM then you call .data(). Then plan to change DOM value. Use .attr and .data to compare

Do you use data() or attr() to update the value?
These functions store data differently, and are not in sync with each other's changes.
My guess is that you used attr('data-diff', 'xxx') to update the value, instead of data('diff', 'xxx').

Yep! I have used attr('data-diff', 'xxx').

Indeed, data values read from the attributes but are cached/independent. You should use an approach consistent with the code reading the value.
