问题描述
我正在开发一个简单的聊天应用程序,单击刷新"按钮时可以查看更新的数据,但是可以定期从服务器刷新数据(因为我的聊天记录已远程存储在数据库中)
I am developing an simple Chat Application, I can view the updated data when I click on the REFRESH Button, BUT can I refresh the data at a regular interval from the Server (as my Chat is getting Stored in the Database remotely)
提前谢谢.
推荐答案
使用 DelayedTask 类:
//create the delayed task instance with our callback
var task = Ext.create('Ext.util.DelayedTask', function() {
//load the list's store here. The list will be automatically updated
listComp.getStore().load(); // Assuming your list component is "listComp"
listComp.refresh();
// The task will be called after each 10000 ms
task.delay(10000);
}, this);
//The function will start after 0 milliseconds
//so we want to start instantly at first
task.delay(0);
//to stop the task, just call the cancel method
//task.cancel();
这应该适合您的情况.
