我要宣布一个全球变量,它从数据储存中得到价值。

var myStore = new Ext.data.Store({
        id:  ID_myStore ,
        proxy: new Ext.data.HttpProxy({
                url:  get.php ,      
                method:  POST 
            }),
        baseParams:{task: "LIST"}, 
        reader: new Ext.data.JsonReader({   
                    root:  results ,
                    totalProperty:  total ,
                    id:  id 
                },[ 
                   {name:  Class , type:  string , mapping:  class }
              ])
    });

        var BestClass = myStore.getAt(0).get( Class );
问题回答

Ooo是一个同化的问题。

你们需要倾听这一呼吁,然后这样做。

var myStore = new Ext.dataStore({......
});
var bestClass;
myStore.on( load ,function(store,record){
 bestClass = store.getAt(0).get( Class );
},this)

请注意,虽然这是如何做到这一点的答案,但它有意与所有其他活动同时呼吁,即活动(你听说),以便在服务器做出回应之前,变数不会界定。
