How to add an item to a list

Question

I am creating a website in HTML and have a form that asks for the users email to get weekly emails and I need help on how to collect all of the emails in one spot. I am a beginner coder.

this is my code for the form:

<div style="text-align:right;">
<form name="email">
<p>Enter your email to get weekly referee tips.</p>
Email<input type="text" name="email"/>
<input type="button" onclick="list" value="enter"/>
</div>
<script>
List<String> list = new ArrayList<>();
int listSize = list.size();
for(int i = 0; i < listSize; ++i)
list.add("Email");
</script>

Oh nooo you're combining Java and Javascript!! `List list = new ArrayList<>();` — ಠ_ಠ, Jul 02 '14 at 19:53
@Rick S like a place to store all of the emails so that i can use it later on — user3799153, Jul 02 '14 at 19:53

@user3799153 `List list = new ArrayList<>();` is not javascript. — admdrew, Jul 02 '14 at 19:58
@JohnBupit java is a programming language and javaScript is a scripting language. JavaScript can only be run on a browser. — user3799153, Jul 02 '14 at 19:59
@user3799153: Umm... that's a link. I'm not asking the question. But, you should probably. — John Bupit, Jul 02 '14 at 20:00
@user3799153 `java is a programming language and javaScript is a scripting language. JavaScript can only be run on a browser` Is wrong for a few reasons... `how do i make it into javaScript?` Write it correctly in javascript! — admdrew, Jul 02 '14 at 20:01

First of all your array size is 0 at first so that for loop never runs. Also, that is Java not Javascript. This would be the correct way to do so in Javascript:

var i;
var list = [];

for(i = 0 ; i < ??? ; i++) {
    list.push("email");
}

Why "???"? Change it to list.length. – nicael Jul 02 '14 at 19:57

`list.length` would be 0 so I'm not sure what this code is trying to accomplish. – jongusmoe Jul 02 '14 at 19:58

Heh, agree... Strange. – nicael Jul 02 '14 at 20:01
thanks @jongusmoe, so now will all of the emails be stored in one place? – user3799153 Jul 02 '14 at 20:03

@user3799153 The funny thing is they won't be. Because size (or length) of empty array is 0. So your loop won't work. It will be simply skipped. – nicael Jul 02 '14 at 20:04
@nicael cant you just change the size to like 15 so that it could hold a max of 15 emails? – user3799153 Jul 02 '14 at 20:06
