In javascript we have array with static number of objects.
objectArray = [{}, {}, {}];
Can someone please explain to me how can I make this number dynamical?

add a dynamic amount of indexes. I'm not really sure what you're asking.thescientist– thescientist2012-04-14 12:23:32 +00:00Commented Apr 14, 2012 at 12:23

You don't have to make it dynamic, it already is. You merely need to add more objects onto the array:
// Add some new objects
objectArray.push({});
objectArray.push({});
console.log(objectArray.length); // 5
// Remove the last one
objectArray.pop();
console.log(objectArray.length); // 4
In JavaScript, array lengths need not be declared. They're always dynamic.
You can modify the individual objects by array key:
// Add a property to the second object:
objectArray[1].newProperty = "a new property value!";

You don't need to specify an array size when first creating the array if you don't want to. You can use:
var objectArray=new Array();
to create the array and add elements by:
objectArray[0] = "something";
objectArray[1] = "another thing";
objectArray[2] = "and so on";
