問(wèn)題描述

是否可以在 :not 選擇器中包含嵌套值?例如:

Is it possible to have nested values inside the :not selector? For eg:

:not(div > div)

每當(dāng)我嘗試它時(shí)，它似乎都不起作用.也許您需要以另一種我還沒(méi)有想到的方式使用它?到目前為止，在我看到的所有示例中，您只能在此選擇器中使用一個(gè)值.

Whenever I tried it, it does not seem to work. Perhaps you need to use it another way which I have not figured out? So far, in all the examples I see, you can only use one value inside this selector.

推薦答案

:not() 一次只接受一個(gè)簡(jiǎn)單的選擇器；Selectors 3 規(guī)范中提到了這一點(diǎn):

:not() only accepts one simple selector at a time; this is mentioned in the Selectors 3 spec:

否定偽類 :not(X) 是一個(gè)采用 簡(jiǎn)單選擇器(不包括否定偽類本身)作為參數(shù).它表示其參數(shù)未表示的元素.

The negation pseudo-class, :not(X), is a functional notation taking a simple selector (excluding the negation pseudo-class itself) as an argument. It represents an element that is not represented by its argument.

您的示例中的簡(jiǎn)單選擇器將是您擁有的兩個(gè) div 標(biāo)記.其他簡(jiǎn)單的選擇器包括類選擇器、ID 選擇器、屬性選擇器和偽類.它不接受多個(gè)簡(jiǎn)單的選擇器，也不接受 > 或空格等組合符.

The simple selectors in your example would be the two div tokens that you have. Other simple selectors include class selectors, ID selectors, attribute selectors and pseudo-classes. It does not accept more than one simple selector, nor does it accept combinators like > or space.

根據(jù)您要準(zhǔn)確選擇的元素，可能無(wú)法排除 div >div:

Depending on which elements you're trying to select exactly, there may not be a way to exclude div > div:

• 如果您只想選擇 div 的子元素，而這些元素本身不是 div，請(qǐng)改用:

• If you only want to select elements that are children of a div, that are themselves not div, use this instead:

div > :not(div)

:not(div) > div

如果你想單獨(dú)使用這個(gè)否定，選擇所有個(gè)其他元素，那么只使用一個(gè)選擇器是沒(méi)有辦法的.

If you want to use this negation by itself, selecting all other elements, then there isn't a way using just a selector.

我能想到的唯一其他可行的 CSS 解決方法是在沒(méi)有 :not() 表達(dá)式的情況下將樣式應(yīng)用于您想要的元素，然后為 div > 撤消它們.div.這適用于您嘗試定位的任何一組元素；缺點(diǎn)是并非所有屬性都可以輕松重置.

The only other viable workaround in CSS that I can think of is to apply styles to the elements you want without the :not() expression, then undo them for div > div. This works for any set of elements you're trying to target; the disadvantage is that not all properties can be easily reset.

或者，如果您使用 jQuery，它確實(shí)支持 :not(div > div) 與 CSS 版本不同，您可以將選擇器放在腳本中，例如，讓 jQuery 將類名應(yīng)用于那些然后元素在您的 CSS 中定位該類.

Alternatively, if you're using jQuery, which does support :not(div > div) unlike the CSS version, you can place the selector in a script and, for instance, have jQuery apply a class name to those elements then target that class in your CSS.
