VCTA auto-filler

fill.js

// Fills in information on a 2018 vcta.dk profile page.
// To run, 
//   1) Navigate to your team profile page in Chrome (seems to have issues on Firefox).
//   2) Right click one of the checkboxes and click "Inspect".
//   3) Go to the "Console" tab.
//   4) Paste the code below and click return.

var distance = prompt("How many km did you bike on weekdays?", 5);

for (var i = 3; i < 65; i += 2) {
    var w = Math.floor((i-3)/2);
    if (w % 7 == 4 || w % 7 == 5 || i == 21 || i == 43)  continue;
    $("input")[i].checked = true;
    $("input")[i+1].style = "visibility: visible";
    $("input")[i+1].value = distance;
}

On firefox, get:

TypeError: $(...)[i] is undefined[Learn More] debugger eval code:6:5

Works on Chrome, but get a few off-by-one misses... Maybe because trying to fill checkboxes for future days that can't be legally filled yet :-)

@jfcorbett: Thanks. Looks like the assumption that VCTA was based on the Old Norse calendar, in which months always start on a specific weekday across years, does not hold. And someone moved Ascension. Guess you'll have to work weekends this year.

Updated to take 2018-specific features into account. See you next year.
