Your page has two inputs with id="username" . 您的页面有两个输入， id="username" 。

Repeating ids is invalid html, but the browser kind of ignores it except that $('#username') finds only the first one so your .focus() handler is bound to that one. 重复id是无效的html，但是浏览器忽略了它，除了$('#username')只找到第一个，所以你的.focus()处理程序绑定到那个。

The first is within the "login_response" div that is hidden until you click the "Login" option, so if you click "Login" and then click the "Username/Email" field that appears you'll see that your event handler runs. 第一个是在“login_response”div中隐藏，直到您单击“登录”选项，因此如果单击“登录”然后单击出现的“用户名/电子邮件”字段，您将看到您的事件处理程序运行。

You have JS issues on load of that page. 您在加载该页面时遇到JS问题。 JS wont work properly thereafter. JS之后不会正常工作。 You need to fix those first. 你需要先修复它们。
