how to create an Array with parametrized name?

[nobody]

hello everybody,

is there a way of creating an array with help of a function that would
accept the name of this array as a parameter and then create global
Array type variable of that name?
so that for example the following code would work as well in browsers as
under Windows Scripting Host:

str = "tableA";

fDoArray(str);
fDoArray("table B");

tableA[10] = 10;
tableB[11] = 11;

I would appreciate any suggestions and help,
regards,
mirek

Hello,

<script>
function fDoArray(arrayN ame)
{
window[arrayName] = new Array();
}

str = "tableA";

fDoArray(str);
fDoArray("table B");

tableA[10] = 10;
tableB[11] = 11;

alert(tableB);
alert(tableA);
</script>

hello,

thanks Vjekoslav and Elias. do you know any solution, that would also
work under Windows Scripting Host?

cheers,

I think using this works as follows:
function output (text) {
if (typeof document != 'undefined' && typeof document.write !=
'undefined') {
document.write( text + '<br>\n');
}
else if (typeof WScript != 'undefined') {
WScript.Echo(te xt);
}
}

function createArray (variableName) {
this[variableName] = [];
}

createArray('ar rayName');
arrayName[0] = 'Kibo';
arrayName[1] = 'Maho';

output(arrayNam e);

The global object does not have a standard name, which is sort of surprising. In
browsers, it can be referred to as 'window'. In other environments it might have
no name at all.

The 'this' variable, when used outside of any function, refers to the global
object. So, at the top of your program, write

var global = this;

and then use 'global' in place of 'window'.

While you're looking for a JS solution, you may want to consider ...

This is easy in VBS - not sure about JS. Although undocumented, the VBS
Execute statement will create a new global variable (despite any Option
Explicit statement), if it does not find the variable name referenced in
either its immediate local variable list or the global variable list. So
the following should work (air code):

sub NewArray (rsArrayName)
execute "dim " & rsArrayName & "()"
end sub

Just Redim after the call, as needed, or you could incorporate the
dimensions and bounds through an additional string parameter, if you wish.
You can wrap the code in On Error ... statements, if you're worried about
potentially Dimming an existing array. You can mix JS and VBS in HTML or
WSC wrappers.

The 'this' variable, when used outside of any function, refers to the global object. So, at the top of your program, write

var global = this;

using try...catch may cause the same code work both in browser and wsh.

var wsh
try{window=this ;wsh=1}catch(e) {}

function fDoArray(x){ret urn window[x]=[]}

fDoArray("table A")
tableA[0]=0
tableA[1]=1
tableA[2]=2

if(wsh){
Shell=WScript.C reateObject("WS cript.Shell")
Shell.Popup(tab leA)
}
else alert(tableA)

This may fail to give the right results if running under some other host
such as ASP. I'm trying to imagine the purpose of the original posters
request?
