[javascript-dev] Re: js question from a newbie

 Sorry for the many questions but i am new to programming generally as well as specifically in javascript .
This is a new problem i am came up with :

I am having an input list sent to a specific function 
where i save it as an array .
The array is declared as a variable within the function , however it seems that i can access it through other functions as well.
Is this normal behaviour ?
I am wondering since this is part of a bigger program , what will happen if i have two arrays with same name .
here is thecode :

 editfontsize = 16 ;
// trying to create a function that takes an input list and create a new array taking into account the specified weights
 var z = new Array() ;   // the array where i copy the a value from an input list
 var x = new Array() ;   // the array where i copy the b value form an input list
 var v = new Array();    // the array where  i copy the weighting value from an input list
			  
		  
function sortit()  // this is where i sort the input array into three distinct arrays
{
count1 = count2 = count3 = 0 ;   // a local counter used to set the elements of the three arrays
v.length = x.length = z.length = (inputweights.length / 3) // here i set the length of the three lists (perhaps not needed)
var t = inputweights.slice();     // copy the initial list
var i = 0;
{for ( i = 0 ; i < t.length ; i ++)
   if (( i % 3) == 0)
      {z[count1] = t[i]
	  count1++ ;}
	  else 
	  {if ((i % 3) == 1)
	  {x[count2] = t[i]
	  count2++ ;}
	  else 
	  {v[count3] = t[i]
	  count3++ ;}}}
post();
post("my a values are " , z) ;
post() ;
post(" my b values are " ,x) ;
post();
post("my weigth values are " , v) ;

}

function bang ()
{ sortit()}



function weights(a)  // saves the input to the weight function into an array
{
var inputweights = new Array ;
post() ;
post("the list contains",arguments.length,
"elements");
if (( arguments.length % 3) != 0)   // checks to see whether we have the correct number of arguments ( a b weight)
 {post();
 post(" wrong number of arguments in the list ") ;
 post() ;}
 else
{for ( i = 0 ; i < arguments.length ; i++)

inputweights[i] = arguments[i];
post();
post(inputweights) ;
post() ;}
}
