I am trying to figure out how to calculate the location to put a sun image on a page (theme really)
sunset location: 378px
sun peak: 18px
sun travel up 360 then down 360px
i already have code that will grab sunrise/sunset times - but i just filled in some times for now....
all in minutes....
i figure i need to calc total sunshine time, time since sunrise, peak time, pixel per min...
but i cant seem to figure out how to figure the current location?
I know i need to test to see if the time since sunrise is past the peak time..
heres what i have so far (just starting)
sLoc is too large... if i am thinking right, there should be a way to calc so that the value is always between 18 and 378 ? right?Code:var SnRs = new Date (new Date().toDateString() + ' ' + '6:30 am'); var SnSt = new Date (new Date().toDateString() + ' ' + '9:15 pm'); var cTime = new Date ( ); var totalsuntime = Math.floor((Math.abs(SnSt - SnRs)/1000)/60); var minssincesunrise = Math.floor((Math.abs(cTime - SnRs)/1000)/60); alert("Total Mins: " + totalsuntime + " Mins Since SR: " + minssincesunrise); var peaksun = Math.round(totalsuntime/2); var pxlpermin = Math.abs(peaksun/360).toFixed(2); var sLoc = Math.round(378 - (minssincesunrise * pxlpermin)); alert(sLoc);
