Do a regex to limit the find and replace

Hi

I need to do a find and replace ("/" with " / ") with java script - but only within <div> tag of a certain class.

So this:
Title 1/2 <div class="theclass">Option1/Option2/Option3</div>
Title 3/4 <div class="theclass">OptionA/OptionB/OptionC</div>

Would get changed to this:
Title 1/2 <div class="theclass">Option1 / Option2 / Option3</div>
Title 3/4 <div class="theclass">OptionA / OptionB / OptionC</div>

Can I use a javascript regex to do this?

Thanks,
Matt

yes you can

$(".theclass").each(function(){
  var html = $(this).html();
  html  = html.replace("/", " / ");
});

Modern browsers do have the querySelectorAll method.
Remember that the method returns a nodelist so you have to loop through it.
var allElements = document.querySelectorAll(".theclass");
for(var x = 0, len = allElements.length; x < len; x++) {
   var el = allElements.item(x), 
       prop = (el.textContent) ? "textContent" : "innerText";
   el[prop] = el[prop].replace(/\//g, " / ");
}

Thank you all for the suggestions!

Proculopsis:
Please can you comment the code?
- why does $(function(){ cuase the function to run straight away?

Why can I use something like this to choose when to run the function:

<script type='text/javascript'>
      function dorep(){
      
            $(".theclass").each( function() {
            
                var text = $(this).text();
                text = text.replace( /\//g, " / " );
                $(this).text( text );
            
            });
            
      }
      dorep();
</script>

Is it becuase it would need to be called after the page had loaded?

Can I limit this futher to only apply to a string of text passes to it (containing divs with those classes - rather than all the html content ...)

Thanks
