这是代码。基本上它会在页面中添加一个注册表单：
var currentTime = new Date($.now())
$(panel).addClass('panel-logged-out')
//this -> $('.am-signup').html('<div class="am-info alert-box secondary">Please sign-in to your CLO account.</div><div class="am-popup" style="top: 596px; left: 0px;"> <div class="am-popup-header"> <a href="javascript:" class="am-popup-close-icon am-popup-close"></a> <div class="am-popup-title"></div></div><div class="am-popup-content"><div id="ajax-link" style="display: block;"><div class="am-layout-two-coll"> <div class="am-layout-two-coll-top"></div><div class="am-coll-left"> <div class="am-coll-content"> <div class="am-form am-login-form"> <form name="login" method="post" action="/amember/login"> <fieldset> <legend> Member Login </legend> <div class="_row" id="recaptcha-_row" style="display: none;" data-recaptcha-theme="red"> <div class="element-title" style="display:none;"></div><div class="element am-element-recaptcha" id="recaptcha-element"> </div></div><div class="_row"> <div class="element-title"> <label class="element-title" for="login"> E-Mail Address </label> </div><div class="element"> <input type="text" id="login" name="amember_login" size="15" value="" autofocus="autofocus"> </div></div><div class="_row"> <div class="element-title"> <label class="element-title" for="pass"> Password </label> </div><div class="element"> <input type="password" id="pass" name="amember_pass" size="15"> </div></div><div class="_row"> <div class="element-title"> <label class="element-title" for="remember"> Remember my password? </label> </div><div class="element"> <input type="checkbox" name="remember_login" value="1"> </div></div><div class="_row"> <div class="element"> <input class="button" type="submit" value="Login"> </div></div></fieldset> <input type="hidden" name="login_attempt_id" value="' + currentTime + '"><input type="hidden" name="amember_redirect_url" value="/amember/signup"> </form> </div></div></div><div class="am-coll-right"> <div class="am-coll-content"> <div class="am-form am-sendpass-form"> <form name="sendpass" method="post" action="/amember/sendpass"> <fieldset> <legend> Lost password?</legend> <div class="_row"> <div class="element-title"> <label for="sendpass"> Enter your E-Mail Address </label> </div><div class="element"> <input type="text" name="login" id="sendpass" size="15"> </div></div><div class="_row"> <div class="element"> <input class="button" type="submit" value="Get Password"> </div></div></fieldset> </form> </div></div></div><div class="am-layout-two-coll-bottom"></div></div></div></div></div>')
由于某种原因，它会使页面滚动到表单，如果我将代码注释掉，问题就会消失。可能是什么问题？

自动对焦？
如果您将自动对焦放在用户名输入字段中，浏览器会立即进行自动对焦
<input .... autofocus="autofocus">
删除它，它可以工作。
