Notes
CLJS date parsing behavior with edge case inputs:
dev:uspooge-app.core=> (new js/Date nil)
#inst "1970-01-01T00:00:00.000-00:00"
dev:uspooge-app.core=> (new js/Date "")
#inst "NaN-NaN-NaNTNaN:NaN:NaN.NaN-00:00"
dev:uspooge-app.core=> (new js/Date)
#inst "2018-03-29T18:35:28.244-00:00"
dev:uspooge-app.core=> (new js/Date 0)
#inst "1970-01-01T00:00:00.000-00:00"
Scripting a table in Cryogen
Table can be found by iterating siblings from a known header. This is true as of
[markdown-clj ""].
function paintItBlack () {
var el = document.getElementById('roles_by_project');
while( el && el.nodeName.toLowerCase() != 'table') {
el = el.nextSibling;
console.log('next');
}
if (el) {
el.style.backgroundColor = 'black';
el.style.color = 'red';
}
}
Run from console via paintItBlack() or via pasting javascript:paintItBlack() in the address bar and navigating.
Can be made general by giving an ID and using CSS.
Interesting selector: document.querySelector('#roles_by_project + table')
