Can you please explain the line in this code

 // Load rules in t开发者_如何转开发o modal 
    $('#rules .text').load('rules.html'); 

as i want to load a page or video in to the dialgue box.

Load the rules.html into the element with id #rules with class .text

rules.html will be loaded from the server and the content is written into the element
