No warning message when document.ready - jQuery

Question

This is my code:

$(document).ready(function() { alert("I am an alert box!"); }); 

when I refresh the page, there is no warning window. Are there any errors?

jQuery seems to be added correctly, but I can't get a warning to test jQuery work. Any ideas on how to make an alert show?

Answer 1

This should work if you downloaded jQuery and you did not use noConflict . He works here , for example.

We cannot help without additional information, but here are some tips:

• Look at your JavaScript console for errors. Most likely there is a syntax error elsewhere on the page that prevents code from ever running from running.
• Make sure you download jQuery correctly.

• If you are using noConflict , change $ to jQuery in your code:

   jQuery(document).ready(function() { /* ... */ }); 

Answer 2

Did you enable the jQuery library before calling in the document?

 <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script> ... <script type="text/javascript"> $(document).ready(function() { alert("I am an alert box!"); }); </script> 

Answer 3

This should definitely work. Be sure to download jQuery before invoking these snippets.
Take a look at the javascript console for any error

Answer 4

Some features:

• jquery doesn't overlap
• the script has a typo
• you may have another javascript that creates the problem.

Answer 5

Try using:

 (function($) { $(document).ready(function() { alert("I am an alert box!"); } })(jQuery); 

If this doesn't work as well as the other answers, then check firebug for errors. You can find it here if you are not already using it.
