javascript - JQuery - Stopping Event Bubbling in all Browsers -

-

i have massively nested gui controls - when they're clicked or changed or whatever need stop event going further dom tree. needs work across browsers.

at point i've got rather clunky js code:

//do in response original user action //leave @ that. try {         e.stoppropagation();     }     catch (ex) {      }     try {         event.cancelbubble();     }     catch (ex) {      }      try {         event.preventdefault();     }     catch (ex) { } ...

this work, smells , feels wrong (personally loathe empty catch blocks). there neater x-browser trick can use?

if use jquery event.stoppropagation() work fine. jquery unifies event handling.

in general if, want test special browser methods, can so:

if(event.stoppropagation) {     event.stoppropagation(); } else if...

this jquery doing. creates wrapper event , provides unified interface.

the name of event object defined you. event object passed first argument event handler. have setup event handler accept parameter, e.g.:

$('selector').click(function(foo) { // event, e, bar, whatever want     foo.stoppropagation(); });

typically e or event used.

Javascript line number mapping -

magically formatted comments change reported line number of javascript errors in browsers; this: //@line n "f" n line number , f file name. unfortunately, //@line appears ungoogleable. know there documentation on feature, , browsers support it?

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
