You are assigning, when you should be calling. On top of that you are fetching the value wrong.

number.push(document.getElementById('myform')['input'].value);

You are adding the id of the form as a string. You have to add the value of the field, so that you can get it later:

var number= []; 
function myFunction() 
{ 
    var input = document.getElementById('input');
    number.push(input.value);

    var x=document.getElementById("box"); 
    x.innerHTML=number.join('<br/>'); 
}

Actually, this code is assigning the value of the input to the property 'push' on the object 'number'.

i don't understand what you say. Actually i have the numbers 1,2,3.. after push to array using "items.push(values) ". its display like this. ['1','2','3,']. But i want [1,2,3] like this how to do

To convert the values to Numbers you will have to call parseInt(value, base) on them (eg.: var num = parseInt(input.value, 10);).
