如何实现如下功能_PHP

PHP代码:——————————————————————————–
脚本说明:
把如下代码加入<body>区域中
<script LANGUAGE=”JavaScript”>
<!—ecms -ecms Begin
oldvalue = “”;
function passText(passedvalue) {
if (passedvalue != “”) {
var totalvalue = passedvalue+”\n”+oldvalue;
document.displayform.itemsbox.value = totalvalue;
oldvalue = document.displayform.itemsbox.value;
}
}
// End –>
</script>

请选择
第一项
第二项
第三项
第四项
第五项
第六项

你可以自己选择一下:
