我在我网站上的选择框中使用以下jQuery multiselect脚本，问题是当您从mysql数据库重新加载记录时，jquery脚本不会重新加载选择选项。如果我创建一个新记录，它将它保存到数据库就好了，但如果我重新加载以前创建的记录，则选择框只是空白。如果我关闭jquery脚本，那么盒子会在html中重新加载。
当重新加载数据时，下拉箭头也不再有效，因此单击箭头不再显示选择菜单项，但是如果新记录正常工作。

这是我在模板index.php文件＆gt;＆gt;
中使用的代码 <!-- Multiselect Library-->
<script type="text/javascript" src="./multiselect/jquery.ui.multiselect.js"></script>
<script>
$(function() {
// initialize the plugin
$('select').multiselect();
$('.w-options').multiselect({
label: '-- Select Your Options --',
minWidth: 300,
maxWidth: 400,
scroll: 80
});
})
</script>

我不确定这是否相关，但在firebug中我收到以下错误＆gt;＆gt;
TypeError：document.getElementById（“path”）为null [打破此错误]
var folder = document.getElementById（“path”）。value;
