我正在为此创建链式选择下拉列表我正在使用库但我的功能无法正常工作，如果我第二次选择它或者如果我选择第二行链接，则第一次选择的值将被禁用选择item.Link库here。我需要它来动态生成多行链接选择..我的代码如下（它只是一个示例，表明这是动态生成的）..我也不是得到任何错误。

答案 0 :(得分：0)
您需要在加载页面时初始化链式选择，而不是单击。
我从select中删除了onclick个事件，并将JS更改为：
$(function() {
$('select[name="mark"]').each(function() {
var id = this.getAttribute('id');
$('#series-'+id.substr(5,1)).chained('#'+id);
});
});
这会使用名称＆＃39;标记＆＃39;遍历每个选择，使用它的ID提取数字（使用substr（））并找到相应的＆＃39;系列＆＃39;选择将其链接到。
编辑： 对于动态添加的行，应在附加行时初始化链式选择。
