c++ - Javascript function only works within a function (with c interface) -

-

i new javascript , writing api getting server status c++ code that's running underneath. understand question may (or may not) project dependent, i'm wondering if has insight of possibly wrong here.

so want call "checkserverstatuscpp()" function, implemented in c++ on "manager.cpp". (i reusing else code , need compile , interface automatically generated. attach info possible.)

i found if wrap call within function, native c++ code executed. 

a = function(){ manager.getserverstatuscpp(); }; a();  // no problem calling function in manager.cpp

otherwise won't work

manager.getserverstatuscpp();   // function getserverstatuscpp() in manager.cpp never called.

here related files.

home.html

<!doctype html>   <head>     <!-- other js/css files in here. -->      <script type="text/javascript" src="js/interface.js"></script>     <script type="text/javascript" src="js/system.media.manager.js"></script>     <script type="text/javascript" src="js/man.js"></script>   </head>    <body>      <fieldset> <legend> <b> server status </b> </legend>       <div class="pad10">             <p> <a onclick="refresh()" id="refresh" href="#"> refresh </a></p>       </div>     </fieldset>       <script>     var manager = new system.manager("1");      function refresh() {         // works - native function called.         = function(){manager.getserverstatuscpp();};         a();          // if put function in c++ not executed.         manager.getserverstatuscpp();     }     function ongetserverstatus(myobject) {         //do     };      </script>    </body> </html>

man.js (i rewriting auto-generated function where)

system.manager = system.media.imanager.extend({      init : function(instance) {         this._super(instance);         this.count = 0;     },      getserverstatuscppcallback: function( myobject ) {         console.log("getserverstatuscpp-->"  + json.stringify(myobject));         ongetserverstatus(myobject);     },     });

system.media.manager.js (this file automatically generated)

system.media = system.media || {}; system.media.imanager = system.interface.extend({      init : function(instance) {         this._super("system::imanager", instance);     },      getserverstatucppscallback: function(  myobject ) {         console.log("getserverstatuscpp-->"  + json.stringify(myobject));     },     getserverstatuscpp: function() {         this.call(         {"method": "imanager::getserverstatuscpp", "params":{ } }, this.getserverstatuscppcallback, []);     },  });     /**      * end of imanager interface     */  });

note: manager.cpp, manager.h native c++ code, , imanager.h implement js interface.

any hint appreciated!
