针对“BOOTSTRAP时间控件显示在模态框下面的bug修复”的问题,我提供以下完整攻略:
问题描述
在使用BOOTSTRAP时间控件时,当该控件被放置在模态框(Modal)中时,会出现控件被模态框遮挡,无法选取的bug。这是因为模态框Z-index值的默认设置会使得该控件表现异常。
修复步骤
要解决这个问题,我们可以通过以下步骤:
- 首先,需要将BOOTSTRAP时间控件的Z-index值与模态框保持一致。
.datepicker {
z-index:1052 !important;
}
- 然后,可以将该CSS代码添加到一个单独的CSS文件中,例如style.css文件中,并在HTML文件中引用该CSS文件。
<link rel="stylesheet" href="style.css">
这样就能够修复该问题,使得BOOTSTRAP时间控件能够显示在Modal中。
示例说明
以下是两个示例,说明如何在HTML文件中实现以上步骤:
