I am trying to highlight (temporarily) words in html. I can successfully edit the text content so that the
<mark>
tags are in the correct place in the text string, and it appears I am saving the edited string correctly, BUT....

the text displayed in the browser does not change!

here is the code:
$(document).ready(function (e) {
      $('#submit').click(function (e) {
          try {
              var $inputTxt = $('#search');
              result = $inputTxt.val();
              alert(result);
 

      $('p').each(function () {
 
          var a=$(this).html().toString();
          var aindx=[];
 
          while(a.indexOf(result) >= 0){
 
              //alert("string found "+a.indexOf(result)+" position");

              var b=a.substring((a.indexOf(result)+result.length));
 
              if(aindx.length > 0) {
                  var prev=aindx.length-1;
                  aindx[aindx.length]=a.indexOf(result)+aindx[prev];
                  $(this).html(a.substring(0,(aindx[aindx.length]-1))+'<mark id="tmprry">'+result+'</mark>'+a.substring(aindx[aindx.length+result.length-1]));
              } else {
                  aindx[0] =a.indexOf(result);
                  $(this).html(a.substring(0,(aindx[0]-1))+'<mark id="tmprry">'+result+'</mark>'+a.substring(aindx[0]));
              }
 
              //insert mark around position

              a=b;
          }
 

                  });
 

 
          } catch (ex) { e.preventDefault(); }
      });
