我想在选择子下拉计数时添加子文本框。我尝试了 jsfiddle 上的单独代码，该代码正在运行http://jsfiddle.net/hs7t8/。有两个下拉列表是在客人选择下拉菜单上创建的。它会在单击添加房间按钮时动态生成两个下拉菜单。第一个是成人，第二个是儿童。在子下拉列表的选择中，我想根据子下拉列表的选择添加文本框。但它没有添加到页面。请帮助我完成http://jsfiddle.net/pYRj3/1/上的运行代码

创建标记时不要使用属性 onselect。它不会着火。

相反，在添加子下拉列表后，将更改事件绑定到下拉列表。On Need More Room selected: $('#hc_f_children').bind('change', function() { // 你的代码在这里，它添加了那些文本框 });

在按下添加房间时： $('#hc_f_children_'+ forage).bind('change', function() { // 你的代码在这里，它添加了那些文本框 });
