EXT core API-Ext. Fly

Syntax: Fly (string/htmlelement El, [String named]): Element

Note:

•  
  • Get a global shared floating element El. If there are multiple floating elements, you can use the name to avoid potential conflicts.
  • Some people ask what are the advantages of this? The advantage is big. If there are 1000 elements, you need to call their hide to hide them. If Ext. get will create 1000 element objects. If fly is used, only one object will be created. This greatly improves the performance. Therefore, it is better to use fly for batch operations.
  • What should I first understand about fly?Flyweight (meta Mode)

Example:

• VaR CLS = ext. Fly ("input_id"). getattributens ('ext ', 'cls ');
• This. rowheight = ext. Fly (this. View. getnode (0). getheight ();

This function is very useful.
