我很愚蠢,并使用绝对定位在 jsFiddle 中构建了一个 Web 小部件,因为它只是一个快速原型,用于向某人展示该功能如何工作。
好吧,我们决定现在就使用它,而我正忙着转换元素以利用相对定位。另外,我正在尝试将其转换为 jQuery UI 小部件,因此我希望所有内容都设置好,以便它可以毫无问题地转储到页面上。
小部件可以在这里看到。基本上它是一个搜索框,允许使用最左边的按钮进行一些过滤。
组件如下:
- #refine:最左边的按钮。
- #refineDropdown:单击优化按钮时出现的下拉菜单
- #search : 输入框
- #dropdown : 直播型搜索过滤框
- #submit:最右边的搜索按钮
问题:创建widget时,定位是相对还是绝对?如果我在一个页面上有多个这样的实例,下拉菜单的位置应该独立于它们在页面上的位置,但我不完全理解定位和 HTML 排列以使其工作。
