这是范围问题：

onForgotPasswordClick在$("#main-page").on('pageinit')上运行的匿名函数内定义，但在该函数之外（在HTML中）调用。这是不可能的。但是，没有什么能阻止你在该范围内调用它。在页面顶部的script元素中添加以下行：

$(document).on('click', '#btnLogin', onForgotPasswordClick);

...然后从按钮中删除onclick处理程序：

<button type="submit"  id="btnLogin" data-theme="b">
    Submit</button>
