javascript - How to split a string at the first `/` (slash) and surround part of it in a `<span>`?

Question

I want to format this date: <div id="date">23/05/2013</div>.

First I want to split the string at the first / and have the rest in the next line. Next, I’d like to surround the first part in a <span> tag, as follows:

<div id="date">
<span>23</span>
05/2013</div>

23
05/2013

What I did:

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<div id="date">23/05/2013</div>
<script type="text/javascript">
  $(document).ready(function() {
    $("#date").text().substring(0, 2) + '<br />';
  });
</script>

Answer 1

Using split()

Snippet :

var data =$('#date').text();
var arr = data.split('/');
$("#date").html("<span>"+arr[0] + "</span></br>" + arr[1]+"/"+arr[2]);  

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="date">23/05/2013</div>
