I have a form with a date picker which allows the user to select only the month and year. Upon submitting the form The value it gets from the form is:
v <- rep(FALSE, 1e6)
v[5e5-1] <- TRUE
v[5e5+1] <- TRUE
library(microbenchmark)
microbenchmark(rangeWhich(v), shortCircuit(v))
# Unit: microseconds
# expr min lq median uq max neval
# rangeWhich(v) 751.252 884.8805 1109.527 1115.995 1163.135 100
# shortCircuit(v) 60712.586 61004.2760 61396.715 61994.517 72382.216 100
I need to use this to create 2 dates. I need the 1st of July and the 31st of July. I can create the 1st no problems using:
$the_Date = $_POST['month_Year'];
echo 'month date: '.$the_Date.'<br />';
// echos 'month date: July 2015' in this example
But I don't know how to create the $last_Of_Month seeing as not all months end on the 31st. Any help would be greatly appreciated

When using document.querySelector("button").addEventListener("click", function() {
html2canvas(document.querySelector("#elem"), {
canvas: canVar,
width: widthVar,
height: heightVar,
background: undefined,
letterRendering: true,
useCORS: true
}).then(function(canvas) {
console.log('Drew on the existing canvas');
});
}, false);
, the value date()
returns the number of days in the month.
