</html>First, this is my first time learning JS.
So, I have a text-box, a submit button, and a display button. When I enter a number in the text-box, and click submit, it shows the number. I enter my second number and clicking the submit button shows me the second number. Then I click on the display button, it will shows the number 1 and number 2 in order. If I have more inputs in the text-box, the display button will show the entire list of all the inputs from the array.
Thank you!

- So, the submit button just reads out the current input, but the display button shows an entire list of all the inputs. – Nicole Commented Dec 10, 2014 at 8:22

- I did Google. @AkshayKhandelwal But still don't know how to do it. Could you please help me? Thank you!! – Nicole Commented Dec 10, 2014 at 8:24
- seriously? you have to look for how to get an element by ID and then get it value and then push in the array.. – Akshay Khandelwal Commented Dec 10, 2014 at 8:27

Reset to default 2Well, since it's your first time and you're learning I won't just give you the answer, but I'll point you in the right direction.
You want to attach a click event on the submit button to add the value to an array, and then print the array on click of the display button.
i think first you must google for this. I write something and you can improve this. I only want to give an example.
HTML:
<input type="text" id="inputbox">
<br/>
<button type="button" id="submit">Submit</button>
<button type="button" id="display">Display</button>
<br/>
<div id="screen"></div>
JS:
var inputArray = [];
var input = document.getElementById('inputbox');
var screen = document.getElementById('screen');
document.getElementById('submit').onclick = function () {
inputArray.push(input.value);
screen.innerHTML = input.value;
};
document.getElementById('display').onclick = function () {
screen.innerHTML = inputArray
};
