如何重新加載存儲每X秒？

Question

我正在使用ExtJS 4 MVC。

有沒有辦法每隔X秒重新加載一次Store？

我想把代碼放在Controller的某處。

Answer 1

setInterval(function(){ 
    // Use Ext.getStore to reference your store from the controller 
    var myStore = Ext.getStore('YourStore'); 
    // Pass in an object of the changes you want to be made to the store 
    myStore.proxy.extraParams = { key:'sencha'}; // replace with your own object 
    myStore.load(); 

},3000); 

Answer 2

在Extjs FYI可以通過Ext.util.TaskRunner執行。 示例代碼：

var runner = new Ext.util.TaskRunner(), 
clock, updateClock, task; 

clock = Ext.getBody().appendChild({ 
    id: 'clock' 
}); 

// Start a simple clock task that updates a div once per second 
updateClock = function() { 
    clock.setHtml(Ext.Date.format(new Date(), 'g:i:s A')); 
}; 

task = runner.start({ 
    run: updateClock, 
    interval: 1000 
});
