angularjs - Angular performance with tabs and tables -


i build new single page web application think main view quite complex , tring decide whether use angular.js. concern whether there data-binding causing performance of ui become sluggish.

the app have view consisting of 2 panels. 1 have 8 tabs each containing table 3 cols, 40 rows , 1 col in each row having list of numbers (upto 4 numbers) each number clickable (clicking number causes happen in other pane). considering using ng-repeat directive dynamically create tabs , tables , list of numbers data provided backend content different different users. think mean 8 * (2 + 4) * 40 (1920) items having watches added $watch list. think means lot of things checked each time round $digest loop although these items never change once have been created first time.

the 2nd pane have other tabs , items although not many in first pane on there on 2000 items involved data-binding if use angularjs , ng-repeat.

is many items 1 view when using angularjs i.e. ui performance become sluggish number of items?

are there alternative ways of dynamically creating tabs , tables using angularjs don't use ng-repeat in order keep number of data-binding items down?

some optimizations can suggest of

  • look @ bindonce directive. not create watch once data bounded. should fix of issues.
  • use directives ng-if these destroy\create dom based on conditions. if tab not in focus point having data bounded it. binding in time. , maybe destroy page dom once focus on tab lost (with ng-if) only.

also test app dummy data, verify how real performance , whether makes sense try second option have mentioned.

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/
