Yet again... the error "Variable $ is undefined" pops up while attempting to incorporate sIFR

Here is the beginning of my file:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>My title</title>
<link rel="stylesheet" type="text/css" href="css/style.css" />
<script src="js/update.js" type="text/javascript"></script>

<!-- sifr -->
<link href="sifr207/sIFR-screen.css" rel="stylesheet" type="text/css"  media="screen" />

<script src="sifr207/sifr.js" type="text/javascript"></script>
<script type="text/javascript">  
$(document).ready(function()  
  {  
       if(typeof sIFR == "function")
       {
           sIFR.replaceElement("sifr", named({sFlashSrc: "sIFR-2.0.7/corporateacon-reg.swf", sColor: "#FF0000" , sWmode: "transparent"}));
       };
   });
</script>
<!--  -->
</head>

I am puzzled as to why the '$(document).ready(function()' function is not being recognized, considering that I have included sifr.js before that specific call.

If anyone has any suggestions, I would greatly appreciate it!

Best regards, supervision

Answer №1

Make sure to include jQuery.js in your file!

Since SIFR is a jQuery plugin, it's necessary to first load the base library before sifr.js.

Consider adding

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript></script>
to the start of your script.

Answer №2

It appears that the issue lies in not including a reference to JQuery prior to making that call, which is why '$' is undefined. To resolve this, consider adding the following line of code before:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js" type="text/javascript"></script>

Answer №3

The reason why sIFR is lacking a $ function is likely because it does not align with the structure of Prototype.js, jQuery, or any other library that utilizes this particular variable name.

Answer №4

$(document).ready(callback) is a function introduced by the jQuery framework to execute callback once the document parsing has finished. It appears that there is no jQuery script included in your file, hence this function cannot be utilized.

Answer №5

To integrate sifr smoothly, ensure that jQuery is included in the head section of your website prior to loading sifr.
