javascript - 如何使用JavaScript/Jquery在 anchor 中显示动态生成的代码

标签 javascript jquery html

我建立了一种方法，每次用户更改下拉菜单的值时，都会生成一些HTML代码。该代码应该显示在页面上的特定区域，但是我不知道如何在该位置显示即时HTML。

下面的页面是我的index.htm，其中包含代码。它正确显示了我的数组，但是我无法在我的div id = liab_layers中显示它……只是不知道从那里去哪里。

希望有人能帮帮我！

编辑：我已经修改了代码。现在，它显示了我想要的内容，但没有显示在我想要的位置。

没关系，我想通了。这不是一种优雅的做事方式，但是它有效，这就是我所需要的。如果其他人偶然发现此代码并需要一些指导，则在下面的代码中。
