Question

I have a problem running my jsp pages.

My jsp pages has reference to some .js file say (file1.js) and in file1.js I’m invoking the jquery calls like $(document).ready. The IE browser is complaining about the error:

SCRIPT5009: '$' is undefined file1.js, line 225 character 1

I see the same exception on Firefox as well.

I have included the <script src="http://code.jquery.com/jquery-latest.js"></script> and also <script type="text/javascript" src="/js/file1.js"></script> in my jsp.

Answer 1

• Check that you include the jQuery library
• file1.js append to document after jQuery library load (if you already add it).

Add jQuery library like following before any other js load

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>

And one important note

Don’t forget to place all your jQuery code within

$(document).ready(function() {
  // your code
});

in short

$(function() {
   // your code
});
