momentjs.com | The website for momentjs | Web Site library

I'm trying to build horizontal hours slots viewer. So far I found what I need, but in months: https://codepen.io/rsschouwenaar/pen/vOodgO

This is the code:

i am trying my hand at front end development for the first time and am having a little glitch which is not behaving as i thought it would.

The website is calculating ratings for sports teams using ELO derived algos.

Problem 1 : On the EPL Game Results tab it should only have 'ternary algorithm' active on page load, and the tab should have a green underline. Currently nothing is underlined on initial load, and both tabs (ternary and MOV) appear to be active.

Problem 2 : when you click MOV algorithm, and then refresh the page, I need it to just be the MOV algorithm active and underlined. Currently, MOV stays underlined but both MOV and Ternary become active.

Here is the jsfiddle: https://jsfiddle.net/wa7gb43j/

I have created a DataTable that is an attendance tracker and I have sort of changed the format of it in its entirety. Instead of having the status in the cells for each row (P, PTO, TRV, H, etc.), I had the Monday-Friday Dates and styled the rows based off of that attribute, and that became way too much to keep up with and my code readability was trash. I have found a better method to go about this. I am now inserting the Status under each day column header, and based off the day's status, it styles the Department row. If you want to find out the Location of the Employee of that day, all you do is hover over the day status and it brings up a tooltip with the location and Date of that day. Instead of having the date appear in the tooltip (I just want the Location), I have been trying to figure out how to append it to the of #myTable.

I came across https://datatables.net/reference/option/columns.title but this seems to only be updated by Static Data.

Here is my working example (minus the header update):

I have this code to show guests time based on their Timezone and it show also my time, the if time is between 11:00 and 17:00 so we are on line else we are not.

How can I exclude Monday , so when it's Monday it shows an offline message

I have the html table with 5 column as date which I want to convert the date format if the data is not empty.I'm using moment.js for date format.

Now date format is converted perfectly but empty column displays invalid date.So I want to check if the cell is not empty I have tried as JS fiddle

Is it possible to output the current UTC Time in "hh:mm:ss" like "18:00:25"?

I found moment.js with the following code:

Hi, I am trying to generate a moment.js format from the given start time and end time.

I need to save the timezone in a Webflow app and I've written the following simple HTML:

I'm working on an Nodejs system support multi timezone users. Currently, I'm using moment.tz.names() to get list of available timezone. But I found out that some timezone in list is deprecated by this link. I also found this database from IANA. So is there anyway to keep my timezone data up to date? I'm trying to find a way to work with IANA database. Thank you if there are any other approaches.
