 1 Ext.onReady(function(){
 2             //案例一
 3             /*
 4             var countries = [‘Vietnam‘, ‘Singapore‘, ‘United States‘, ‘Russia‘];
 5             Ext.Array.each(countries, function(name, index, countriesItSelf){
 6                 console.log(name);
 7                 if(name == ‘Vietnam‘){
 8                     return false;  //停止循环
 9                 }
10             });
11             */
12             //案例二
