如何在Extjs4中使用加载侦听器

Question

I am learning how to utilize the load event ..how do i go about catching the loading of data.. I just n4ed a sample example.. to understand how it works and how data is manipulated inside the callback function

Thanks

store.addListener("load", dataLoadCallback);


function dataLoadCallBack((store, records, success))


}

Answer 1

store.on('load',/*event*/,dataLoadcallback /*function called*/, this/*scope called*/) 

function dataLoadBackCalled(store, records){ //dont stress about success just yet.
  store.each(function(record)){
      console.log(record.get('id');
  }
}
