Javascript Class Object - Same values Multiple names

Question

I want to create multiple object using a class for example:

function _Class(_number) {
     this.numer = _number;
    }

and i want to make 36 objects with the same attributes but different values. I stuck almost on beggining because i used loop :

for (var i = 0; i < 37; i++) {
name="number_"+i;    
var name=new _Class(i); 
}

and after this code i can't acces to any object. Is there a way that I can create a variable which name is value of array ?

All code:

//test 
function test(x){
    for (var i = 0; i < 37; i++) {
        document.write(x);
    }
}
var pola = [0, 32, 15, 19, 4, 21, 2, 25, 17, 34, 6, 27, 13, 36, 11, 30, 8, 23, 10, 5, 24, 16, 33, 1, 20, 14, 31, 9, 22, 18, 29, 7, 28, 12, 35, 3, 26, 0];
var nazwy_obiektow = new Array(100);
for (var i = 0; i < 37; i++) {
    nazwy_obiektow[i] = "liczba_" + i;
}
function _Klasa_Liczb() {
     this.numer = 1;
    }
for (var i = 0; i < 37; i++) {
    var nazwy_obiektow[i]=new _Klasa_Liczb; 
}
test(liczba_0);

Create the variable outside of the loop. To initialize it to an array, the most concise way is like: var myArray = []; — Mic

You could use an array.

function _Class(_number) {
        this.numer = _number;
 }
 var objects = [];
 for (var i = 0; i < 37; i++) {
    name = "number_" + i;
    objects[i] = new _Class(name);
 }

Then you can see each object in the array (objects[0], objects[1],...).

Done this and I can't acces to the values of object outside the code.

Where is your var objects? Think that the scope of your variables is the function which was declared. Define your objects outside of functions.
