Javascript Question

Check if year is leap year in javascript

function leapYear(year){
var result;
year = parseInt(document.getElementById("isYear").value);
if (years/400){
result = true
}
else if(years/100){
result = false
}
else if(years/4){
result= true
}
else{
result= false
}
return result
}


This is what I have so far (the entry is on a from thus stored in "isYear"), I basically followed this here, so using what I already have, how can I check if the entry is a leap year based on these conditions(note I may have done it wrong when implementing the pseudocode, please correct me if I have)
Edit: Note this needs to use an integer not a date function

Answer
function leapYear(year)
{
  return ((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0);
}
