Search Array in JavaScript
<p>I need to sort through a data set which as you can see I've assigned to the records variable. From that data I need to see if the zip code exists. If the zip code does not exist then I need to move it into the array (There of course will be duplicates) and continue checking the rest of the records, if it does exist I need to do nothing.</p>

<pre><code>// Declare Array
var numbersArray = [];

// Variables
var records;
var zipCode;
var numbers;
var index;
var output;
var outputMessageOne;
var outputMessageTwo;
var count = 0;

output = document.getElementById('outputDiv');
records = openZipCodeStudyRecordSet();

output.innerHTML = "The unique zip codes are: ";

while (records.readNextRecord()) {

    zipCode = records.getSampleZipCode();

    for (index = 0; index &lt; numbersArray.length; index++) {
        if (zipCode === numbersArray[index]) {
            var uniqueZip = false;
            break;
            records++;
        }

        if (zipCode !== numbersArray[index]) {
            numbersArray.push(zipCode);
        }
    }
    output.innerHTML += numbersArray;
}
</code></pre>

<p>}</p>
