});Getting Attribute
var $source = $("img").attr("src");
Just getting into vars with jQuery and because of this I have a question to the last example…is it just your favourite way of naming a variable $source or do I have to do this like this to make it work?
It just appears to be a good way of writing variables that have to do with jQuery return values. I like to use it when setting a jQuery object to a variable — for example, var $elems = $(‘#mydivs’);
This is what I need .
