Question

My javascript gets included multiple times with the script tag, like so:

<script src='code.js></script> <script src='code.js></script> <script src='code.js></script> 

Right now I have this code inside code.js to make my code run only once without overwriting my namespaces:

if(typeof _ow == 'undefined' ){ _ow = {}; // code in here will only run once  _ow.Auth = (function(){ })(); _ow.Template = (function(){ })();  } 

Is there any better structure I could use to make my code only run once?

Answer 1

Are you familiar with Crockford’s Javascript Module Pattern?

A slight variation on how to prevent overwriting the namespace:

var _ow; if(!_ow) _ow = {};
