我想在选择子下拉计数时添加子文本框。我在jsfiddle上尝试了单独的代码http://jsfiddle.net/hs7t8/。在客户选择下拉列表的选择上创建了两个下拉列表。它会在添加房间按钮单击时动态生成两个下拉菜单。第一个是成人，第二个是儿童。在选择儿童下拉列表时，我希望文本框符合选择子项下拉列表。但它没有添加到页面。请帮助我。http://jsfiddle.net/pYRj3/1/

添加房间
答案 0 :(得分：0)
创建标记时，请勿使用onselect属性。它不会开火。
相反，在附加子下拉列表后，将更改事件绑定到下拉列表。 在需要更多房间选择： $（'＃hc_f_children'）。bind（'更改'，函数（）{//此处为您的代码，添加了这些文本框}）;
按下添加房间： $（'＃hc_f_children _'+ forage）.bind（'change'，function（）{//这里的代码，添加了那些文本框}）;
