我正在尝试创建一个下拉菜单，该菜单由我的 RPi 目录的 PHP 列表创建，然后我可以选择一个条目并使用该.load()功能在我的 siteDev.php 页面上显示选定的 HTML 文件内容。
出现的问题是我无法从下拉菜单中传回值以允许我在#results div 中显示内容。

更改以下功能。此函数中缺少附加“+”

function udLoad(sel){
    var value = sel.value;
    alert(value + ' page selected');
    $('#result').load('devUpdates/'value' #container');
}

至

function udLoad(sel){
    var value = sel;
    alert(value + ' page selected');
    $('#result').load('devUpdates/' + value +' #container');
}
