使用 javascript，如何在元素外单击时复制 div 作为 select 元素的行为？
Using javascript, how do I duplicate the behavior of a div acting as a select element when clicking outside the element?
我需要创建一个伪 select 元素来显示 select 中每一行的列。由于 HTML 不允许 <option> 标签包含 HTML，我不得不采用这种方法。
普通 select 元素的一个特点是当您在元素外部单击时它会折叠起来，无论用户单击何处。它可以在文档中，可以在地址栏中，或任何地方。我无法复制该行为。在文档内部进行控制很容易。但是点击地址栏，甚至点击developer/console window，都不行。

我需要创建一个伪 select 元素来显示 select 中每一行的列。由于 HTML 不允许 <option> 标签包含 HTML，我不得不采用这种方法。
普通 select 元素的一个特点是当您在元素外部单击时它会折叠起来，无论用户单击何处。它可以在文档中，可以在地址栏中，或任何地方。我无法复制该行为。在文档内部进行控制很容易。但是点击地址栏，甚至点击developer/console window，都不行。
