it's a series of <td><input type="checkbox">engine name</td>
, within per-wave tables. So, for the blind bags (individual engines):
x = document.querySelectorAll("#blindbags table input[type='checkbox']")
for(var i=0; i < x.length; i++) if (!x[i].checked) x[i].parentElement.style.display = "none";
first line builds a list of all the checkboxes;
second line loops through them, and if they're not checked, hides their parent (td
) container.
for the blister packs (where the checkbox is in a td
adjacent to the engine list) you need to go up one more level before hiding:
x = document.querySelectorAll("#blister table input[type='checkbox']")
for(var i=0; i < x.length; i++) if (!x[i].checked) x[i].parentElement.parentElement.style.display = "none";
"none"
Then use one of the print view
buttons at the bottom to get rid of some of the extraneous crap before you copy-and-paste or print or whatever you're doing with the list.
