Question

Why doesn’t this work?

<script type="text/javascript" src="js/jquery-1.8.1.js"></script>
<script type="text/javascript">
    $(document).ready(function() {
            $("body").html($("body").html().replace(/&reg;/g, '<sup>&reg;</sup>').replace(/®/g, '<sup>&reg;</sup>').replace("\u00AE" , '<sup>&reg;</sup>'));
        };
    );
</script>

Firebug in Firefox gives this in the console:
“SyntaxError: missing ) after argument list”

But, this breaks the WordPress entirely…

<script type="text/javascript">
    $(document).ready(function() {
            $("body").html($("body").html().replace(/&reg;/g, '<sup>&reg;</sup>').replace(/®/g, '<sup>&reg;</sup>').replace("\u00AE" , '<sup>&reg;</sup>'));
        }
    );
</script>

The basic of this function is to find every single registration mark in the body, and replace it with “^®”
If this function is capable in PHP as well, that’s preferable.

Answer 1

It seemed like the best thing to do was to go into the database and just run a sql query to replace all registration marks and wrap it in “” tags.

However, this did work on individual elements. (Like adeneo said, it’s not a good idea to replace the entire site HTML… which broke the site for me)

<script type="text/javascript"  src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"> </script>
<script type="text/javascript">
    $(document).ready(function() {
        $("h1").html(
            $("h1").html()
                .replace("®", "<sup>&reg;</sup>")
                .replace(/&reg;/g, '<sup>&reg;</sup>')
                .replace(/®/g, '<sup>&reg;</sup>')
                .replace("\u00AE" , '<sup>&reg;</sup>')
        ); 
    });
</script>
