Question

我是Java-Web-Programming的新手，每当我放置JSP标签时，我的非GUI Netbeans-Codes都编译得很好，但每当我放置JSP标签时，我的GUI Netbeans-Codes都会出错：＆lt;％！％GT;和＆lt; %%＆gt;。下面是我的Netbeans-GUI代码之一，用于简单的＆＃34; Salary Tagging System＆＃34; 3个标签对应3个文本字段（dspID，dspNAME，dspSAL）。什么是正确的JSP-Tagging方式？

function getpath($id, $arr, $level = 0) {
    $result = array();
    foreach($arr as $key => $value){
        if($id == $value['id']){
            $result[] = $value['name'];
            $id = $value['parent'];
            if($id != 0){
              $result = array_merge($result, getpath($id, $arr, $level+1));
            }else{
                break;
            }
        }
    }
    return $level ? $result : implode('->',array_reverse($result));
}
echo getpath(13,$arr);

}`

One way to make your application both gui and web capable would be to redesign it using the MVC principle. Put simply that separates the display part from data and processing.
