extJs学习基础4 Ext.each的用法

 Ext.onReady(function(){
             //案例一
             /*
             var countries = ['Vietnam', 'Singapore', 'United States', 'Russia'];
             Ext.Array.each(countries, function(name, index, countriesItSelf){
                 console.log(name);
                 if(name == 'Vietnam'){
                     return false;  //停止循环
                 }
             });
             */
             //案例二
             var StudentsJSON = {
                 student:[{
                     name: '张三',
