JavaScript

jsfiddle.net/jhfgj5Lr/2

I'm trying to have the .wrap-span's parent, .wrap, be determined when the .wrap-span is clicked, and then look for its .wrap-p child element and apply .fadeIn(). I try through this, it doesn't work.
I ask for your help

Write a sample code.
Most likely, your this changes when it gets into the handler function. To get rid of the problem, you need to store this in a variable.
