Here is a JQuery tutorial which I don't understand.
$("[href!='#']") =>select all elements with an href attribute NOT equal to "#".
$("[href$='.jpg']") =>select all elements with an href attribute that ends with ".jpg".
what is the $ inside ? what it does there ? There is already a $ outside . I guess $ has something to do with the href attribute that ends with . But how ? Could you please throw somelight on this syntax ? Can I apply this any other places ?
