  • 0

I have 2 arrays for the dates. I don’t understand why the first element works, and the second doesn’t works. That is the same function. Second and third (4th 5th… etc ) should work. I don’t understand. Maybe it’s bug of datepicker, because I also cannot use the onChange function.

[2010,8,10] – [2010,8,15] -> works
[2010,7,10] – [2010,7,10] -> doesn’t works.

    I’m having a hard time parsing if block, but I don’t think it matters. I’m guessing it’s because you’re returning false once it doesn’t match your first set of dates, so your loop will never get past the first iteration.

    I think you want to move the return false outside of your loop…
