javascript - JS - Call function by name (in object notation) -

i want clean old code , optimize it, uses same code. (with different names of functions call)

i make easier example , no, don't write on game. example looks more comprehensible explaination of issue.

character.sleep(1); character.changename(name); character.useitm(1423); 

easier example:

object.function(parameters) 

target this:

myfunc(funcname,value) {     character.{funcname}(value); }  $('.btn_sleep') { myfunc('sleep','1'); } $('.btn_cname') { myfunc('changename','harold'); } $('.btn_uitem') { myfunc('useitem','1423'); } 

first thought use eval(), because no user-input come near of functions. dislike idea because of performance lost.

then looked around alternatives , found window[] , new function() solution.

but dont idea how use it, when want dynamcially call function name in object-notation. (or in worser cases, when you've result if-condtion function, called object-notation.)

could help?

the best way know how dynamically call functions using bracket notation because allows set object path variable

function myfunc(funcname,value) {     character[funcname](value); }  myfunc('sleep','1');
