asynchronous - How to pass data to external javascript script, loaded asynchronously -


i followed answer https://stackoverflow.com/a/7719185/842837 load javascript asynchronously. how pass data external file?

current code:

<script id="js-widget-o2ba1y" type='text/javascript'>     (function() {         function async_load(){             var config = {                 'module': 'hyperdesign',                 'user-name': 'john doe',                 'user-email': 'john@doe.com'             };             var id = "js-widget-o2ba1y";             var embedder = document.getelementbyid(id);             var s = document.createelement('script');             s.type = 'text/javascript';             s.async = true;             var u = 'http://external.javascript.file.js';             s.src = u + ( u.indexof("?") >= 0 ? "&" : "?") + 'ref=' + encodeuricomponent(window.location.href);             embedder.parentnode.insertbefore(s, embedder);         }          if (window.attachevent)             window.attachevent('onload', async_load);         else             window.addeventlistener('load', async_load, false);     })(); </script>

how send config external js file?

edit going though google analytics code. load script asynchronously, , use config data 3rd party website:

<script> (function(i,s,o,g,r,a,m){i['googleanalyticsobject']=r;i[r]=i[r]||function(){ (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new date();a=s.createelement(o), m=s.getelementsbytagname(o)[0];a.async=1;a.src=g;m.parentnode.insertbefore(a,m) })(window,document,'script','https://www.google-analytics.com/analytics.js','ga');  ga('create', 'ua-xxxxx-y', 'auto'); ga('send', 'pageview'); </script>

i need same thing, in more readable way.

no, can't pass parameters , have script read them in.

technically grab them tag, real mess.

could output script block before include file?

<script type="text/javascript">              var config = {                 'module': 'hyperdesign',                 'user-name': 'john doe',                 'user-email': 'john@doe.com'             };   </script>  <script id="js-widget-o2ba1y" type='text/javascript'>      //you code   </script>

by that, config object attached window name space => window['config'];

therefore , alternative , remain same code have , however, need replace var config= window.config=; , config visible external js . 

<script id="js-widget-o2ba1y" type='text/javascript'>     (function() {         function async_load(){             window.config = {                 'module': 'hyperdesign',                 'user-name': 'john doe',                 'user-email': 'john@doe.com'             };             var id = "js-widget-o2ba1y";            //-----rest of code </script>
