How to make ajax call for every 5 seconds?

[renganathan]

Hi All,

I want to make ajax call for every 5 seconds.

Can you guys suggest me how to do that ?

Use this :

//we store setInterval's return value in case we want to clear the interval later on with clearInterval(myInterval)
var myInterval = setInterval(function() {
//here you put your AJAX request
}, 5000//5 seconds in ms);

PS.
of course if it is what you were looking for and I understood you correctly

You could use Ext.util.DelayedTask

Example

        this.pollTask = new Ext.util.DelayedTask(function(){
            Ext.Ajax.request({
                url: pollUrl,
                scope: this,
                success: function(r) {
                },
                failure: function() {
                }
            });
            this.pollTask.delay(5000);
        }, this);


        this.pollTask.delay(5000);

According to Sencha docs here : http://docs.sencha.com/core/manual/content/timers.html, the correct way would be to use Ext.TaskManager.

Still I wonder why is it advised to use this solution instead of basic setInterval.
Can anyone explain?
