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

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>

See the JSFiddle.

But this does not work. Can someone help me with jQuery?

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>

Fiddle

When you split this string ---> 23/05/2013 on /

var myString = "23/05/2013";
var arr = myString.split('/');

you'll get an array of size 3

arr[0] --> 23
arr[1] --> 05
arr[2] --> 2013

Answer 2

Instead of using substring with a fixed index, you'd better use replace :

$("#date").html(function(t){
    return t.replace(/^([^\/]*\/)/, '<span>$1</span><br>')
});

One advantage is that it would still work if the first / is at a different position.

Another advantage of this construct is that it would be extensible to more than one elements, for example to all those implementing a class, just by changing the selector.

Demonstration (note that I had to select jQuery in the menu in the left part of jsfiddle's window)

Answer 3

You should use html():

SEE DEMO

$(document).ready(function(){
    $("#date").html('<span>'+$("#date").text().substring(0, 2) + '</span><br />'+$("#date").text().substring(3));     
});

Answer 4

try

date.innerHTML= date.innerHTML.replace(/^(..)\//,'<span>$1</span></br>')

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

Answer 5

var arr = $('#date').text().split('/');
console.log(arr);
$("#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>

Answer 6

use this

<div id="date">23/05/2013</div>
<script type="text/javascript">
$(document).ready(function(){
  var x = $("#date").text();
    x.text(x.substring(0, 2) + '<br />'+x.substring(3));     
});
</script>

Answer 7

Try this

$("div#date").text().trim().replace(/\W/g,'/');

Answer 8

var str = "How are you doing today?";

var res = str.split(" ");

Here the variable "res" is kind of array.

You can also take this explicity by declaring it as

var res[]= str.split(" ");

Now you can access the individual words of the array. Suppose you want to access the third element of the array you can use it by indexing array elements.

var FirstElement= res[0];

Now the variable FirstElement contains the value 'How'
