==Tips==
=== Detect User Agent ===
To detect if the user agent is Nintendo 3DS Browser :
<script type="text/javascript">
if (navigator.userAgent.indexOf('Nintendo 3DS') == -1) { //If the UserAgent is not "Nintendo 3DS"
location.replace('http://www.3dbrew.org'); //Redirect to an other page
}
</script>
* You can check <em>navigator.platform=="Nintendo 3DS"</em> as well.
=== Scrolling ===
Scrolling can be altered by modifying <em>document.body.scrollTop</em> and <em>document.body.scrollLeft</em>. However, there are drawbacks related to working with these properties:
* Both properties return 0 when accessed
* Setting one property resets the other property's scroll position
In order to set both at the same time (without either resetting to 0), use <em>window.scrollTo</em>.
=== Events ===
==== Key Events ====
The following buttons trigger the <em>onkeydown</em>, <em>onkeypress</em> and <em>onkeyup</em> events:
{|class="wikitable" width="20%"
! Code !! Button
|-
| 13 || A
|-
| 37 || Left
|-
| 38 || Up
|-
| 39 || Right
|-
| 40 || Down
|}
The events cannot have their default action cancelled. Other buttons do not trigger key events.
==== Touch/Mouse Events ====
<em>onmousedown</em>, <em>onmouseup</em> & <em>onclick</em> are all triggered by the browser. However, the <em>onmousedown</em> event doesn't trigger until you lift the stylus or you've held it on the screen for ~2 seconds—which is when text selection mode is activated—making it pretty much the same as <em>onmouseup</em>. The events cannot have their default action cancelled.
The <em>onmousemove</em> and common touch/gesture events are not supported.
== Screen Resolution ==
The up screen resolution is 400×240. However, the viewable area in the browser is only <b>400×220</b>.
The touch screen resolution is 320×240. However, the viewable area in the browser is only <b>320×212</b>.
You can have a page span both screens. However, the browser will behave as if the bottom screen is the only active screen and the top screen is scrolled off. This is important when computing CSS coordinates. Items positioned from "bottom" will be positioned based on 220px and not the full 432px of both screens.
== Using Both Screens ==
Generally the easiest way to accomplish the correct layout is to create HTML elements that "contain" the top and bottom screens. Here's an example:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=400">
<style>
body { margin: 0px; }
#topscreen { width: 400px; height: 220px; overflow: hidden; }
#bottomscreen { width: 320px; height: 212px; overflow: hidden; margin: 0 auto; }
</style>
</head>
<body>
<div id="topscreen">Top Screen</div>
<div id="bottomscreen">Bottom Screen</div>
</body>
</html>
This scheme allows the page to be easily manipulated through JavaScript. In order to have the window snap to the correct position, use the following JavaScript code:
window.setInterval(function () {
window.scrollTo(40, 220);
}, 50);
This automatically resets the position if the user accidentally scrolls the page.
