querySelectorAll 其中 class 不包含 'hide'
querySelectorAll where class does not contain 'hide'
document.querySelectorAll('.giftUpsell-offer-desc + a')
Returns3个元素:
[
<a href="https://www.qa.example.com" class="button button--primary button--wide u-hide" someattribute="fish">
Extend & Save
</a>, <a href="www.qa.example.com" class="button button--primary button--wide u-hide" someattribute="cats">
Extend & Save
</a>, <a href="www.qa.example.com" class="button button--primary button--wide" someattribute="dogs">
Extend & Save
</a>
]
我需要找到元素当前可见的 "someattribute" 的值。我知道 class 属性不包含 "hide" 的元素是我想要的。
如何将上述选择器编辑为 return 这个特定的 <a>
元素?在这个例子中是给狗的。
使用:not(<selector>)
伪class:
.giftUpsell-offer-desc + a:not(.u-hide)
使用 :not
伪选择器:
var els = document.querySelectorAll('.giftUpsell-offer-desc + a:not(.u-hide)');
console.log(els);
<div class="giftUpsell-offer-desc"></div>
<a href="https://www.qa.example.com" class="button button--primary button--wide u-hide" someattribute="fish">Extend & Save</a>
<div class="giftUpsell-offer-desc"></div>
<a href="www.qa.example.com" class="button button--primary button--wide u-hide" someattribute="cats">Extend & Save</a>
