    <pre><code>Users = new Array; Passwords = new Array; function LogIn() { Users[10] = "username" Passwords[10] = "password" Username = user.value; Password = pass.value; for (i = 0; i &lt;= Users.length; i++) { if (Users[i] == Username) { if (Passwords[i] == Password) { alert("yay!"); } else { alert("nay"); } } } } function Register() { Username = user.value; Password = pass.value; Users.push(Username); Passwords.push(Password); } </code></pre> <p>Alright, so I'm teaching myself Javasctipt in my free time and I decided that the best way would be to just mess around with it for a while. I am trying, currently, to build a primative "log in"/"register" webpage/function and I've obviously run into a few problems. </p> <p>Global variables. I need the arrays "Users" and "Passwords" to be global, but the way I have it set up now, I think they are initialized every single time I call the function-set. So, I guess I'll ask both my questions like this: I realize that arrays probably aren't the best thing for a project like this, however, how do I get the values I store in the arrays to persist from run to run?</p> <pre><code>&lt;script type="text/javascript" src="LogIn.js"&gt;&lt;/script&gt; &lt;script type="text/javascript" src="Register.js"&gt;&lt;/script&gt; &lt;body&gt; Username: &lt;input type="text" id="user" /&gt; Password: &lt;input type="password" id="pass" /&gt; &lt;input type="button" value="Log In" onClick="LogIn()"/&gt; &lt;input type="button" value="Register" onClick="Register()" /&gt; &lt;hr /&gt; &lt;/body&gt; </code></pre>

    1. COthe vars will persist for the life of the page. Until you refresh and/or move off the page, they'll stick around. If you need them to persist over refreshes/navigation, you'll have to use a cookie.

    2. CO@Marc B Ok, that's what I thought. However, I'm creating numerous arrays of undefined length with values at [10] - that's my main question.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
