jquery src returning "Undefined" in Wordpress

Asked

I have a function to create extra fields in the profile editor of users of a site in Wordpress. A part of it creates two image upload fields (media Uploader with thickbox), and a snippet in jQuery to fill in a text input with the image URL, and a placeholder (img) with the image itself. That’s basically the result:

inserir a descrição da imagem aqui

The media Uploader must provide the url with:

var imgurl = $( 'img', html ).attr( 'src' );

It’s working normally on localhost, but when I put it on the server, it doesn’t work. The log shows "Undefined", and interestingly only in Chrome (but works in Chrome on localhost).

Any ideas? If relevant, I can post the entire code.

  • if you change the var imgurl to a fixed value it works?

  • Yes, it works normal. So I guess there’s only one problem left with the $( 'img', html ).attr( 'src' ); (I just don’t know which...)

  • I think the problem is using $... check out: http://codex.wordpress.org/Function_Reference/wp_enqueue_script#jQuery_noConflict_Wrappers

I discovered by researching the OS in English (here). Instead of using:

imgurl = $( 'img', html ).attr( 'src' );

...just use

imgurl = $( html ).attr( 'src' );

Strange is that the first way works on localhost... Thanks to those who tried to help.
