Sections : new Array()  ...bis  the_info[Info]...Italian SplitString : English  Italian
The following Script shows the addressing properties of the array elements
<Script language=JavaScript>
<!--
var demo=new Array();
demo['a']='q'
demo['b']='w'
demo['c']='e'
demo['d']='r'
demo['e']='t'
demo['f']='y'
document.write(demo.b)
document.write(demo['b'])
//-->
</Script> This Script returns :
The output of conditional expressions in the right side cell shows how the array the_info[Info] refill its locations with the very values of array Info[i] e Value[i]
 <Script language=JavaScript>   /* Another view */
<!-- Here the_info[Info] array is artificially generated.
the_info=new Array();
for (i = 0; i < 3; i++) {
var Info = new Array('User','age','tel');// Left side elements
Info=Info[i];
var Value = new Array('vittorio','53','0881 631796'); //...Right
Value=Value[i];
the_info[Info] = Value; document.write(the_info[Info])
if(the_info.User==Value)
document.write(the_info.User+' ')
if(the_info.age==Value)
document.write(the_info.age+' ')
if(the_info.tel==Value)
document.write(the_info.tel) } document.write(the_info['age'])
// Returns : -->
</Script> ( See source code )
When the interpreter runs down the Script i=[0] and get into loop body , finds at first place : 'User' then : 'vittorio' and when the new array is reached ( i.e. : the_info[Info] = Value ) releases the values into the declared array ( where-from these will be at disposal for retrieving ), then the interpreter re-enter the loop ... i=[1] and releases : 'age' & '53' ; and later ... i=[2] releases : 'tel' & '0881 631796'
