windows - Jscript - Variable in function name, possible? -

i have function names in array in wsh jscript, need call them in loop. al found here javascript - variable in function name, possible? doesn't work, maybe because use wsh and/or run script console, not browser.

var func = [     'cpu' ];  func['cpu'] = function(req){     wscript.echo("req="+req);     return "cpu"; }  (var item in func) {     wscript.echo("item="+ func[item](1)); } 

the result is:

c:\test>cscript b.js microsoft (r) windows script host version 5.6 copyright (c) microsoft corporation 1996-2001. rights reserved.  c:\test\b.js(11, 2) microsoft jscript runtime error: function expected 

(this wscript.echo line)

so, there way call function using name in variable in environment?

no, problem not wsh not command line.

this have in code:

var func = [     'cpu' ]; 

that is, array 1 element in it. content of element 'cpu' , index 0. array length 1.

func['cpu'] = function(req){     wscript.echo("req="+req);     return "cpu"; } 

this adds aditional property array object not 1 element array content. if test, array length still 1.

for (var item in func) {     wscript.echo("item="+ func[item](1)); } 

this iterates on content of array. item retrieves index of each element in array , used retrieve content. content of array 1 element, index 0 , contents string (cpu). not function, so, can not call it.

the problem mixing way work objects , way work arrays.

for array version

var func = [     function cpu(req){         return 'called cpu('+req+')';     },     function other(req){         return 'called other('+req+')';     } ];  func.push(     function more(req){         return 'called more('+req+')';     } );  (var item in func) {     wscript.echo('calling func['+item+']='+ func[item](1)); }; 

for objects version

var func = {     cpu : function(req){         return 'called cpu('+req+')';     },     other : function(req){         return 'called other('+req+')';     } };  func['more'] = function(req){     return 'called more('+req+')'; };  (var item in func) {     wscript.echo('calling func['+item+']='+ func[item](1)); }; 

as can see, similar, if work arrays, should add elements array, not properties, for in iterate on elements in array. in case of object approach, add properties object , for in iterates on properties of object.

very similar, not same.
