Package: | Ext.util |
Defined In: | DelayedTask.js |
Class: | DelayedTask |
Extends: | Object |
The DelayedTask class provides a convenient way to "buffer" the execution of a method, -performing setTimeout where a new timeout cancels the old timeout. When called, the -task will wait the specified time period before executing. If durng that time period, -the task is called again, the original call will be cancelled. This continues so that -the function is only called a single time for each iteration.
-This method is especially useful for things like detecting whether a user has finished -typing in a text field. An example would be performing validation on a keypress. You can -use this class to buffer the keypress events for a certain number of milliseconds, and -perform only if they stop for that amount of time. Usage:
var task = new Ext.util.DelayedTask(function(){
- alert(Ext.getDom('myInputField').value.length);
-});
-// Wait 500ms before calling our function. If the user presses another key
-// during that 500ms, it will be cancelled and we'll wait another 500ms.
-Ext.get('myInputField').on('keypress', function(){
- task.delay(500);
-});
-Note that we are using a DelayedTask here to illustrate a point. The configuration -option buffer for addListener/on will -also setup a delayed task for you to buffer events.
