javascript daily URL change

[sgraystar]

Thanks, that works but I don't understand why it did not change every iFrame?

The code below is working.
I kept the search for .hourlyforecast but perhaps there is a more elegant way of specifying the wanted class or Custom name in the load event.
The forecastDate string is to get the local time instead of UTC.

Code:

$(function() {
  $('iframe').one('load', function() {
    let d = new Date();
    let forecastDate = d.getFullYear() + '-' + ('0' + (d.getMonth() + 1)).slice(-2) + '-' + ('0' + d.getDate()).slice(-2);
    $('.hourlyforecast').find('iframe').attr('src','https://reg.bom.gov.au/places/vic/melbourne/forecast/detailed/#d' + forecastDate);
  });
});
