拿起一个元素并为其添加CSS规则

I have a CMS (Joomla) site, with the ® sign on many places. Instead of going through every module and adding a span to it, than making it superscript, is there a JS or jQuery code I can use, to pick this sign up and make it superscript?

我有一个CMS(Joomla)网站,在许多地方都有®标志。而不是通过每个模块并添加一个跨度,而不是使其成为上标,是否有我可以使用的JS或jQuery代码,选择这个注册并使其成为上标?

I know it is a long shot, but if that actually exists it would be super cool.

我知道这是一个很长的镜头,但如果真的存在,那将是非常酷的。

Thanks.

EDIT: If possible with pure JS as I have a complex slider and including jQuery brings errors

编辑:如果可能使用纯JS,因为我有一个复杂的滑块,包括jQuery带来错误

You can actually do this using JavaScript / jQuery, but it is a very costly function!

你可以使用JavaScript / jQuery实际做到这一点,但它是一个非常昂贵的功能!

$(document).ready(function () {
  $("body").html($("body").html().replace(new RegExp('®', 'g'), '<sup>&reg;</sup>'));
});

Note 1: This is terrible in performance!

注1:这在性能上很糟糕!

Note 2: This may remove the events, so better replace "body" with a selector, that has only Rich Text Content!

注意2:这可能会删除事件,因此最好将“body”替换为仅包含Rich Text Content的选择器!

Solution for Note 2:

注2的解决方案:

$(document).ready(function () {
  $(".user-content-area").html($(".user-content-area").html().replace(new RegExp('®', 'g'), '<sup>&reg;</sup>'));
});

There may be chances like using ® for the same. So, for those:

有可能使用®对于相同的。所以,对于那些:

$(document).ready(function () {
  $(".user-content-area").html($(".user-content-area").html().replace(new RegExp('&reg;', 'gi'), '<sup>&reg;</sup>'));
});

There's an alternative version for the regex! You can use split() and join() too! Instead of:

还有正则表达式的替代版本!你也可以使用split()和join()!代替:

.replace(new RegExp('®', 'g'), '<sup>&reg;</sup>')

Change it with:

改变它:

.split('®').join('<sup>&reg;</sup>')
.split('&reg;').join('<sup>&reg;</sup>')

Note: This is case sensitive! :(

注意:这是区分大小写的! :(

Better use some CSS instead of some javascript for that. CSS:

更好地使用一些CSS而不是一些javascript。 CSS:

.sup { vertical-align: super; }

HTML:

<span class="sup">&reg;</span>

You could easily do a search/replace on many files using Sed

您可以使用Sed轻松地对许多文件进行搜索/替换

find . -name "*.php" -print | xargs sed -i 's/\&reg;/<span class=\"sup\">\&reg;<\/span>/g'
