- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
MVC 有很多值得称赞的地方,但我一直遇到的一个问题是 ID 名称冲突。
我在使用 foreach 循环生成网格时首先注意到它。在 SO 的帮助下,我发现解决方案是使用编辑器模板。
现在我对标签有同样的问题。
我使用这个引用来了解如何使用标签; http://blog.roonga.com.au/search?updated-max=2010-06-14T19:27:00%2B10:00&max-results=1
我的标签的问题是我正在使用带有日期选择器的日期字段。在上面的示例中,通过引用生成的容器元素的唯一 ID 来避免 ID 名称冲突。但是对于日期选择器,容器的 ID 无关紧要,只有日期字段的 ID 很重要。所以发生的情况是,如果我创建与第一个相同的第二个选项卡,当我更新我的第二个选项卡时,第一个选项卡上的日期会更新。
所以下面是我的 View ,以及显示日期的部分 View 。当我单击“添加缺勤 1 天”按钮时,我为该屏幕创建了一个选项卡;

最佳答案
问题似乎是 DOM 只有一个 NullableOtherLeaveDate 条目。由于使用了 ID,这似乎是合乎逻辑的。您还可以将哈希添加到 ID 中。如果您需要将该 ID 与任何 jQuery 匹配,您可以使用部分选择器,如下所示:
$('input[id*=NullableOtherLeaveDate]')
