WordPress & jQuery: “$ is not a function”
If you are trying to add your own jQuery code to WordPress, and have had the error “$ is not a function” show up on Firebug, here is the fix:
Convert all dollar signs ($) to ‘jQuery’
The dollar sign is reserved in WordPress for the Prototype library, which is why it errors out. For example, instead of:
$().ready(function() {
$("#select_me").show();
});
Change it to:
jQuery().ready(function() {
jQuery("#select_me").show();
});
lol….
Thanks alot.
I change $ -> $$
Because when I used jQuery appear “is not a function”.
BR,
little rangda
Thanks this saved me a ton of time and worked fine, didn’t have to use $$ like the other commenter suggested.
dont both with this lot. do it like this:
(function($) {
// your code with dollars here
})( jQuery );
enclose your code in this type of structure.
thanks too much..
This saved me some hassle, thanks mate!
Thank you so much this saved my time:)
thank you
Thanks.
Thanx a lot
Many many thanks.
@Gabriel … good call … all the scripts using that construct work fine …
GRACIAS this was killing me!!
thanks a ton dude i was tweaking my code for a long tym coz of this error… in previous wordpress versions it was working out fine but since the 3.3 and 4 i was getting this error in firebug and chrome inspector..jslint also couldnt solve this lol
The thumbnails stopped working after updating to WordPress 3.4. I edited the script by replacing the $ with jQuery. The thumbnails work! Many thanks!
Thanks a lot man. I was struggling with the darn code and with all i could think of… when in the end it was just this small thing… -_-’ lol Thank you a lot
