Creating new object instances in a loop

rated 0 times [ 146] [ 6] / answers: 1 / hits: 15279 / 12 Years ago, sat, january 5, 2013, 12:00:00

I'm trying to create a new object for each item in an array by looping. The names of the objects should be based on the key of the array.

So for this array:

var arr = new Array(

    some value,

    some other value,

    a third value

);

Would result in three objects:

alert(object1.value);

alert(object2.value);

alert(object3.value);

The code I have thus far (but isn't working) is:

// Object

function fooBar(value) {

    this.value = value;

    ...

}



// Loop

var len = arr.length;

for (var i = 0; i < len; i++) {

    var objectName = object + i;

    var objectName = new fooBar(arr[i]);

}

Does what I'm asking for even make sense?

You have to make an array of the objects also

var objs = new Array();



for(var i = 0; i < len; i++) {

  objs[i] = new fooBar(arr[i]);

}



alert(objs[0].value);
