我想创建一个类似的窗口，其中包含如下图所示的表单。
在我的例子中，当点击顶部导航栏上的登录链接时，包含表单的屏幕被调用。
我的方法是使用包含表单及其元素的隐藏 div，同时调用函数来启用和禁用 div 的可见性。
目前我正在将 div 样式设置为隐藏，如 public.css 中的 log_in_form_div 类所示。
下面是我的 HTML 代码:

我的问题是:
我采用的方法是最好的吗？
我似乎在尝试启用和禁用 div 的代码的 javascript 位中出错？
谢谢
最佳答案
对于您的导航菜单，您可以像这样使用 jquery。你只需要用这个改变导航标签
<nav id="topbar">
<a id="logo_link" href="">ABCD corp</a>
<ul>
<li><a href='#' id="login">LOG IN</a></li>
<li><a href='#'>HOW IT WORKS</a></li>
<li><a href='#'>FEATURES</a></li>
<li><a href='#'>abcd.com</a></li>
</ul>
</nav>
在你的脚本标签中添加这个。
<script>
$(document).ready(function(){
$('#login').click(function(){
$('#log_in_form_div').show();
});
$('#btn_cancel_log_in_form').click(function(){
$('#log_in_form_div').hide();
});
$('.carousel').carousel( {
interval: 3500 //changes the speed
});
)};
</script>
