Appending to an array declared in a .js file from a different .html file

Question

I have an external javascript function that just declares an empty array. I have two files that use this array, the first one appends to the array using the push method, the second one searches through the array and looks for the values added to the array, if it's there. My problem is that every time I try to search the array, It comes up empty, which means nothing is added to the array.

This is the content of my .js file:

   var users = [];

This is the javascript part of my .html file:

  <script type="text/javascript" src="array.js"></script>
  <script type="text/javascript">
           var uname = "someone";
           var pword = "something";
           users.push(uname);
           users.push(pword);
  </script>

You would have to add the search script at the end of everything. — plalx

Create a jsFiddle.net example. For your examples I can see You only add data o your array. — op1ekun

If you are referencing the array-creation-script from two different files, that does not mean you are working with the same array object. — Bergi

I suggest you to namespace your application to avoid conflicts. The following would help:

//array.js
var myApp = {
    users: [] //This will create a new var users with empty array
};

//JS in the HTML file
<script type="text/javascript" src="array.js"></script>
<script type="text/javascript">
    var uname = "someone";
    var pword = "something";
    if (myApp && myApp.users) {
        myApp.users.push(uname);
        myApp.users.push(pword);
    }
</script>

Also I suggest you to load array.js at the top of your HTML and place the inline script at the end of the HTML.
