CSS 选择器匹配数字大于的类 [英] CSS selector to match class with number greater than

问题描述

我有一个使用 Sencha Touch 2 开发的移动混合应用程序，需要根据运行的 iOS 版本进行一些自定义.

I have a mobile hybrid application developed with Sencha Touch 2 which needs some customization based on the iOS version it is running on.

我曾经在我的 Sass 样式表中有以下选择器:

I used to have the following selector in my Sass stylesheet:

.x-ios-7 {
/* put here iOS7 customizations */

}

现在在 iOS8 中，框架添加了一个 x-ios-8 类而不是 x-ios-7 并且自定义显然被破坏了.

Now with iOS8 the framework adds a x-ios-8 class instead of x-ios-7 and the customizations are obviously broken.

有没有办法用 x-ios-{i} 其中 {i} >= 7 选择所有类?

Is there a way to select all classes with x-ios-{i} where {i} >= 7?

允许使用 Sass.我不想对已知案例进行硬编码.

Sass usage is allowed. I don't want to hardcode known cases.

推荐答案

SASS

@for $i from 3 through 6 {
    .x-ios-#{$i} { background:blue; }
}

生成

.x-ios-3 { background:blue; }
.x-ios-4 { background:blue; }
.x-ios-5 { background:blue; }
.x-ios-6 { background:blue; }

常规 CSS

div { width:100px;height:100px;border:1px solid black;float:left; }
[class^="x-ios-"]:not([class*="1"]):not([class*="2"]) { background:blue; }

<div class="x-ios-1"></div>
<div class="x-ios-2"></div>
<div class="x-ios-3"></div>
<div class="x-ios-4"></div>
<div class="x-ios-5"></div>
<div class="x-ios-6"></div>

或者为您的用例提出第 n 个配方..

Or come up with a nth recipe for whatever your use case is..

:nth-child(n+5) matches children 5, 6, 7, ...
:nth-child(2n+5) matches children 5, 7, 9, ...
:nth-child(-n+7) matches children 1, 2, 3, 4, 5, 6, 7
:nth-child(-3n+8) matches children 2, 5, and 8
