<html>
<head>
<title>tab</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script type="text/javascript">
function switchTab(ProTag, ProBox) {
for (i = 1; i < 5; i++) {
if ("tab" + i == ProTag) {
document.getElementById(ProTag).getElementsByTagName("a")[0].className = "on";
} else {
document.getElementById("tab" + i).getElementsByTagName("a")[0].className = "";
}
if ("con" + i == ProBox) {
document.getElementById(ProBox).style.display = "";
} else {
document.getElementById("con" + i).style.display = "none";
}
}
}
