Most efficient method for dynamically changing HTML content with JavaScript

Can anyone provide guidance on how to switch HTML content using JavaScript?

For example:

if($sid == 0)
 {insert one HTML code}
else
 {insert another HTML code}

Which method is preferable - LESS, jQuery, CSS3, etc?

Answer №1

It is recommended to utilize jQuery's load function while transferring the HTML content as shown below:

if($sid === 0) {
  $('#result').load('ajax/test.html', function() {
     alert('The load operation was successful. (sid is equal to 0)');
  });
} else {
  $('#result').load('ajax/othercontent.html', function() {
     alert('The load operation was successful. (sid is not equal to 0)');
  });
}

Answer №2

jQuery was created to fulfill the task you have requested (and many other tasks as well) in a browser-independent manner.

<html>
<head>
<style>
  .hidden { display: none; }
</style>

<script type="text/javascript">
  $(function() {
    if(condition) $('#div1').show();
     else $('#div2').show();
  }); 
</script>
</head>

<body>
  <div id="div1" class="hidden">...</div>
  <div id="div2" class="hidden">...</div>
</body>
</html>

Answer №3

I'm uncertain about the purpose of

if($sid == 0)

but if you wish to modify the HTML content, you can utilize

$("#id").html("<span>your html</span>");
