如何在不更改第一个js文件的情况下使用另一个功能向一个javascript程序添加功能

Question

On the surface, this question seems easy (and admittedly I am new to javascript so it may be), but here are the details:

The work I do is in Drupal, therefore I work predominately with CSS and Drupal's interface. However, for the current function I am doing, I need to use Javascript to add an overlay onto an existing Google map. I have already written the javascript, and the map is working, but the location of my javascript is inside the javascript of the module I am using to make the map. If I keep it there, then once the module updates, my work will be overridden by the new javascript. Therefore, what I need to do is add my functionality inside a new javascript file saved elsewhere that can effect the javascript inside the map module without having to write anything into the map module. I have seen plenty on this that requires a call to be placed in the original js file, but that won't work, as it will be overridden on the next update.

You can easily add JS for specific view...

function yourtheme_preprocess_views_view(&$vars) {
    $view = $vars['view'];
    // Make sure it's the correct view
    if ($view->name == 'your-view-name') {
        // add needed javascript
        drupal_add_js(drupal_get_path('theme', 'your-theme') . '/your-js.js');
    }
}
