如何自动为每个_blank链接添加图标？ [英] How to add an icon automatically to every _blank link?

问题描述

我在页脚中添加了以下脚本，自动将target =_ blank添加到每个外部链接：

I have the following script added to my footer that is automatically adding target="_blank" to every external link:

<script type="text/javascript">
    function linkopener(a) {
    var b = a ? "_blank" : "_self";
    var c = document.links;
    for (var i = 0; i < c.length; i++) {
        if (c[i].href.search("www.mydomain.tld") == -1) {
            c[i].addEventListener("click", function () {
                    this.target = b;
            });
         }
    }
};
$(document).ready(function(){
    linkopener(true);
});
</script>

现在我想将其扩展到每个链接末尾的一个小指标，以便用户知道它是一个外部链接，为此我找到了这个解决方案： https://stackoverflow.com/a/52058198 但是我不能让它发挥作用。如何将其整合到我的工作脚本中？

Now I would like to extend this to a small indicator at the end of every link so that a user is aware that it is an external link and for that I found this solution: https://stackoverflow.com/a/52058198 but I cannot make it work. How to integrate this into my working script?

推荐答案

我希望这段代码可以帮到你

I hope this code will help you

function linkopener(a) {
    var b = a ? "_blank" : "_self";
    var c = document.links;
    for (var i = 0; i < c.length; i++) {
        if (c[i].href.search("www.mydomain.tld") == -1) {
            /*
            c[i].addEventListener("click", function () {
                    this.target = b;
            });
            */
            c[i].target = b;
            c[i].className += ' external-link' 
         }
    }
};
$(document).ready(function(){
    linkopener(true);
});

a.external-link {
  position: relative;
  padding-right: 20px;
}
a.external-link:after {
  content: '\2197';
  position: absolute;
  right: 5px;
}
