您正在尝试将处理程序绑定到您的输入元素，然后它才成为 DOM 的一部分：

$('#rmb').keyup(handlerFn); // when #rmb is not present yet the jQuery object will be empty and no handler will be bound

而是使用事件委托，将处理程序绑定到document始终存在的对象：

$(document).on('keyup', '#rmb', handlerFn); //document will always be present, no matter if #rmb is added to the DOM lateron, so binding will be successful
