JS indexOf Always Returns -1

Question

I've got an array thats being built from a CSV file, the array builds just fine:

0: Array[80]
    0: "AM"
    1: "AX"
    2: "AR"
    3: "JR"
    4: "AC"
    5: "AF"
    etc...

I'm then trying to verify that a string taken from a text input appears at some point in the array. The variable for the value of the text input is created, but the indexOf() always returns as -1.

I originally thought that maybe the variable being compared (airlineCode) was an object and that was the issue, but converting it to a string gives me the same results. After that I thought maybe I could just circumvent the indexOf() by using jQuery.inArray(), also got the same result. Code block looks like:

$("#employeeLoginButton").click(function(){
    $.ajax({
        url: "/template/AirlineBlock/airlineCodes.csv",
        async: false,
        success: function (csvd) {
            data = $.csv2Array(csvd);
            var airlineCode = document.getElementById('airlineCode').value;
            airlineCode = String(airlineCode);
            var found = data.indexOf(airlineCode);
            console.log(airlineCode + found);

            if(found != -1) {
                sessionStorage.setItem("airlineVerified", true);
                window.location.href = "http://somesite.com";
            } else {
                alert("Nope")
            }
        },
        dataType: "text",
    });
});

From what i can tell data is probably undefined unless you have it in the global scope somewhere. — James Harrington, Sep 02 '15 at 17:13
Maybe you should alert(airlineCode); right before your .indexOf also check if it has any white spaces, this can mess you up. — Buildersrejected, Sep 02 '15 at 17:15
what @RocketHazmat is trying to say is that `complete` will run reguardless of the response type from the server, `success` will run if the response is ok and `fail` will run if the response is an error. So having both success and complete is redundant — stackoverfloweth, Sep 02 '15 at 17:15
Thanks @dtanders, I had wondered the same thing, but no whitespace. — Josh Burdick, Sep 02 '15 at 17:20
@RocketHazmat Combining `complete` into `success` gives the same result, but I see your point. Thanks. — Josh Burdick, Sep 02 '15 at 17:25
@JoshBurdick: Try to `console.log(data)` and `console.log(airlineCode)`. One of those things isn't what you think it is. — gen_Eric, Sep 02 '15 at 17:27
For debugging purpose, could always try your own indexOf to loop through elements, make sure you have no junk in there. — aggaton, Sep 02 '15 at 17:29
Ahhh! `data` was two-dimensional. `var found = data[0].indexOf(airlineCode);` was the trick (the addition of the [0] index). @RocketHazmat — Josh Burdick, Sep 02 '15 at 17:33
@JoshBurdick: Now that I look at the question again, that info was right there: `0: Array[80]`. — gen_Eric, Sep 02 '15 at 17:35
