如何在另一个函数中访问javascript自定义全局变量

Question

I have developing phonegap android application. I'm trying to establish the communication between javascript and android java classes.

For Communication i have used addJavaScriptInterfaceMethod in android main activity.So that i can use java object and method in javascript.

following is the Java Code :

 public class Activity extends DroidGap
  {
       @Override
       public void onCreate(Bundle savedInstanceState) 
       {

            super.onCreate(savedInstanceState);
            setIntegerProperty("loadUrlTimeoutValue", 60000);
            super.loadUrl("file:///android_asset/www/jq3.html");
            MapTablesWrapper table = new MapTablesWrapper();
            super.appView.addJavascriptInterface(new MapTablesWrapper(), "tables");

           }
     }

And in javascript :the following code does not printing the table value.It's alerting undefined

var tableName = tables.getTableName();
function(){
       alert(tableName);

 }

And if i declare var table inside the function.Its printing the tableName and following code is

 function(){
       var table = tables.getTableName();
       alert(tableName);
 }

But i would like to declare variable outside of the function and want to use that varaible in inside the function.

You can do like

var global = {
    table : null
};

function()
{
   global.table = tables.getTableName();
   alert(global.table);
}

you can rename global as your JS file name, so that this variable can be accessed all the functions in the current file and also in any other JS File by using your fileName.table here it is global.table
