jquery, replace multiple elements recursively -

-

i got stuck following issue. i'm explaining content footnotes. footnotes e.g. [10] have format <sup>[10]</sup>. screenshot of content footnotes

i'm trying replace <sup>[10]</sup> <a href="#m10" data-toggle="modal"><sup>[10]</sup></a> using following jquery:

<script type='text/javascript'> $(window).on('load', function() {     $(function(){         var s = $('sup').html().slice(1, -1);         $("sup").replacewith('<a href="#m'+s+'" data-toggle="modal"><sup>['+s+']</sup></a>');     }); });  </script>

unfortunately code replaces footnotes same/first found footnote - in case, footnotes replaced "10" (see screenshot). want recursively replace each footnote.

i don't know how solve problem got stuck several days. perhaps of guys or girls can me. many in advance.

iterate on each of sup elements , replace corresponding html rather replacing all sup elements. inside of .each() method, this refers current sup element.

based on jquery provided, want:

$('sup').each(function() {   var s = this.textcontent.slice(1, -1);    $(this).replacewith('<a href="#m' + s + '" data-toggle="modal"><sup>[' + s + ']</sup></a>'); });

rather using .slice(), extract digit(s) using .match() method:

$('sup').each(function() {   var s = this.textcontent.match(/\d+/)[0];    $(this).replacewith('<a href="#m' + s + '" data-toggle="modal"><sup>[' + s + ']</sup></a>'); });
