Jquery $.inarray() Not Working Properly With Array Made With Jquery Makearray()

I created an date array using this: var holidays = ['7/24/2010','7/25/2010']; var holidaysArray = jQuery.makeArray(holidays); and then testing to see if myDate (a date object)

Solution 1:

I think you are comparing Date and String objects, that's why you'll get always false.

see:

newDate("12/12/2000") == "12/12/2000"// this is false

EDIT:

Also! note that:

newDate("12/12/2000") == newDate("12/12/2000") // this is false too!

You should compare dates using their epoch time value like this

newDate("12/12/2000").valueOf() == newDate("12/12/2000").valueOf() // this is TRUE

Solution 2:

To summarize others' answers:

1. You already have an array, you don't need to use makeArray().
2. Your array doesn't contain dates, it contains strings.
3. Dates can't be compared directly in JavaScript.

Solution 3:

Basically you want to perform a search (lookup), right?

If you formulate your array like this:

var holidays = [{ date: "7/24/2010" }, { date: "7/25/2010" }];

And create a jOrder table out of it, indexed by date (unique):

var table = jOrder(holidays)
    .index('date', ['date']);

Then you can check the presence of a certain date in the table like this:

if (!table.where([{ date: myDate }]).length) {....}
