copied!<p>I think you're misunderstanding the overall concept of the module pattern, when you need to have a global static variable shared between all your instances then you can declare or initialize your variable with the keyword "var" just before the return statement.</p> <p><strong>Assume that whenever you change those variables all your instances will be impacted by the change</strong>.</p> <pre><code>var slideMenu=function(){ // Declare or initialize your private static variables here var speed, startWidth, time; return { // Public part of your object slide:function(s,passChange){ //To access your variable speed = 20; ... </code></pre> <p>On the other hand if you want to keep variable safe from the global scope, you have to put your variable into the object returned by your function, this is a reliable way to provide <strong>unique per instance properties</strong>.</p> <pre><code>var slideMenu=function(){ // Declare or initialize your private static variables here var speed, startWidth, time; return { // Public part of your object // Declare internal or public properties here menuId : 0, liID : 0, menuLen : 0, ... slide:function(s,passChange){ //To access your private static variable inside functions speed = 20; // To access your public/internal properties this.menuId = s; // for example ;) } </code></pre> <p><strong>To conclude</strong></p> <p>Sometimes to help distinguish between internal / public properties some folks writes a leading underscore on their internal properties (note that properties will still remain accessible from the outside).</p> <p>Hope it helps, good luck!</p>
