Why we need to use multiple version of JQuery Libraries -


i saw lot of sites people using multiple versions of jquery library. doubt why need use multiple versions? can't use latest version only? won't support previous versions functionality?

if using multiple versions, our website loading not slow, trying load multiple versions.

your comments helpful understand things

devesh

a web site using multiple versions of jquery is

  • slower loads , run more code
  • more complex have add hooks ensure each library uses right jquery
  • messy, developers need master different versions

when library uses jquery, library must date. fix libraries version of jquery you'll use site. never try jungle multiple versions of jquery.

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
