I am attempting to check if my Jquery Library is loaded onto my HTML page. I am checking to see if it works, but something is not right. Here is what I have:
<html xmlns="http://www.w3.org/1999/xhtml"> <head> <script type="text/javascript" src="/query-1.6.3.min.js"></script> <script type="text/javascript"> $(document).ready(function(){ if (jQuery) { // jQuery is loaded alert("Yeah!"); } else { // jQuery is not loaded alert("Doesn't Work"); } }); </script> 
743
Type this command in the Chrome Developer Tools Javascript console window to see what version of the jQuery is being used on this page: console. log(jQuery(). jquery);
something is not right
Well, you are using jQuery to check for the presence of jQuery. If jQuery isn't loaded then $() won't even run at all and your callback won't execute, unless you're using another library and that library happens to share the same $() syntax.
Remove your $(document).ready() (use something like window.onload instead):
window.onload = function() { if (window.jQuery) { // jQuery is loaded alert("Yeah!"); } else { // jQuery is not loaded alert("Doesn't Work"); } } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
