Online about this aspect of the code is more and more chaotic, here to tidy up and improve. Add Eventvar addevent = function (obj, type, fn) { if (obj.addeventlistener) obj.addeventlistener (type, FN, false); else if (obj.attachevent) { obj["e" +type+fn] = fn; Obj.attachevent ("On" +type, function () { obj["E" +type+fn].call (obj, window.event); });} ;removing eventsvar removeevent = function (obj, type, fn) { if (obj.removeeventlistener) obj.removeeventlist

The onfocus event is the event that occurs when the cursor falls in a text box. The onblur event is the event that occurs when the cursor loses focus.

For example: memory leaks, recurring events and triggers are flashback execution, and so on. The following is a traditional event method to handle the binding of an encapsulated event: Addevent.id = 1; Event counter function addevent (obj, type, fn) {if (Obj.addeventlistener) {Obj.addeventlistener (type, FN, fal

after the handle attribute is read. Therefore, handleallocated is used to check the existence of the handle, instead of creating it. HideHide controls InvalidateForce Control re-painting PerformSend messages directly to components without passing through windows message system RefreshRequires that the component be re-painted immediately and erased before being re-colored RepaintThe component is required to be re-painted immediately, and the background of the component is not erased before

The Stop command uses the program location initialization, at selection-screen, start-of-selection and get to handle instructions 1. When the command is executed in the initialization event, the system will directly trigger the sending of the application server and client screen elements; 2. In other events, the end-of-selection event will be directly triggered. If you do not want to execute end-of-selection, use return or

To hide the program when you press the Home key: 1: Before Android 2.0, you need to listen to the button event to determine if the back key is pressed. 2: After Android 2.0, the system provides an onbackpressed method, which is used to listen for back-key events. Therefore, you only need to override the onbackpressed method. @ Override Public void onbackpressed { // Implement the home key effect // Super. onbackpressed; this sentence must be noted out

Cancels the browser's default behavior (response) to the event (such as the Implementation code Copy Code code as follows: function Stopevent (evt) { var evt = evt | | window.event; if (Evt.preventdefault) { Evt.preventdefault (); Evt.stoppropagation (); } else { Evt.returnvalue = false; Evt.cancelbubble = true; } } Prevent events from continuing to propagate only (do not cancel the default behavior) C
