Jquery or javascript to add one line break <br /> after x amount of characters in a <div>

I am looking for a way to insert a <br /> after only the first 4 or 5 characters in a <div>.

Example: <div id="wine-name">2008 Cabernet Sauvignon</div>

To display like:

2008
Cabernet Sauvignon

Not sure which would be easier javascript or jQuery. The site is already using jQuery.

Any ideas?

Both the above answers have not considered the fact that the use case might include sentences where the break should be included at the nearest space prior to required limit . i.e. Above methods will break the words at specified index. But in most cases that is not the most suitable solution. Here is my take on this.

function myFunction() {
  var str = "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book";
   //var str = "LoremIpsumissimplydummytextoftheprintingandtypeset tingindustry.Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimensdfdfdfdfsdsds book";
  var originalStr = str;
  str = splitString(str);
  document.getElementById("demo").innerHTML = str;
}
function splitString(str)
{
    var originalStr = str;
      var charLimit = 50;
      var slicedStringList = [];
      var flag = 1;
      while(flag)
      {
        if(str.length <=50)
        {
          slicedStringList.push(str);
          flag=0;
        }
        else
        {
          var tempChar = str[charLimit]
          if(tempChar == ' ' ||tempChar == '\n' ||tempChar == '\r')
          {
            slicedStringList.push(str.substring(0,charLimit));
            str = str.substring(charLimit+1,originalStr.length);
          }
          else
          {
            var tempStr = str.substring(0,charLimit);
            var nearestSpace = tempStr.lastIndexOf(" ");
            if(nearestSpace>-1)
            {
              slicedStringList.push(str.substring(0,nearestSpace));
              str = str.substring(nearestSpace+1,originalStr.length);
            }
            else
            {
              slicedStringList.push(tempStr);
              str = str.substring(charLimit+1,originalStr.length);
            }
          }
        }
         
      }
      var newString = slicedStringList.join("<br>");
      return newString;
}
<!DOCTYPE html>
<html>
<body>

<button onclick="myFunction()">Try it</button>
<p id="demo"></p>
</body>
</html>

But its probably better to go with css instead.(more subtle)

If you are certain that you always want to insert the break after the fourth character, you can do this:

var html = $("#wine-name").html();
html = html.substring(0, 4) + "<br>" + html.substring(4);
$("#wine-name").html(html);

You can see it in action here.

If you want it to instead break after the first word (delimited by spaces), you can do this instead:

var html = $("#wine-name").html().split(" ");
html = html[0] + "<br>" + html.slice(1).join(" ");
$("#wine-name").html(html);

You can see this in action here.

EDITed for your comment:

$(".wine-name").each(function() {
    var html = $(this).html().split(" ");
    html = html[0] + "<br>" + html.slice(1).join(" ");
    $(this).html(html);
});

See it here.

The code in JavaScript would look something like this:

var element = document.getElementById('wine-name');
element.innerHTML = element.innerHTML.substring(0, element.innerHTML.indexOf(' ')) + '<br />' + element.innerHTML.substring(element.innerHTML.indexOf(' '), element.innerHtml.length);

It's probably better to go with JQuery.
