是否可以一次更改网站上的所有定位标记属性? [英] Is it possible to change all anchor tags properties on a website at once?

问题描述

我最近了解到target="_blank"是易受攻击的，我们必须使用rel="noopener".我正在一个网站项目中，所有锚标签都使用target属性.

I have recently learned that target="_blank" is vulnerable and we have to use rel="noopener". I am working on a website project where all anchor tags are using the target attribute.

只需使用以下一项即可更改这些anchor texts的颜色:

It is possible to change the colors of these anchor texts at once just by using:

a {color: blue;}

在网站顶部.

但是如果我尝试做

a {
rel="noopener"
target ="_blank"
}

上面的代码没有任何作用.因为rel和target未包含在CSS中.

The above code does not have any effect. Because rel and target are not covered in CSS.

那么有人怎么为整个站点设置这些attributes?

So how could someone set these attributes for the entire site?

此外，我尝试在w3schools上进行搜索，但是在CSS中他们对此没有任何答案.

Also, I tried searching on w3schools but they don't have any answer to it in CSS.

推荐答案

使用Vanilla JS查找元素.循环然后更改属性.

Find elements using Vanilla JS. Loop then change attributes.

document.querySelectorAll('a[target="_blank"]').forEach(function(el){
    el.setAttribute('rel', 'noopener');
});

然后应用CSS

a[target ="_blank"][rel="noopener"] {
    color: blue;
}
