JsonP Store的load方法
使用jsonP获取store数据时,由于JsonP是异步的,调用完成时store不会立刻更新,因此应该使用callback进行响应。如下:
var store = Ext.getStore('Channel'); store.getProxy().getExtraParams().shopId = shopId; store.load({ callback : function(records, operation, success) { for(var i=0; i<records.length; i++){ // do something } }, scope: this });
