- When using a function as its parameter,
$()will execute the function once the page's DOM is fully loaded.
For instance:$(function(){ /* do something */ }); - When passing a string containing a CSS selector,
$()will return all the HTML nodes which match the selector.
For instance:$('ul#nav'); - That set of nodes can then be assigned to any of jQuery's methods. For instance, if you want to hide the navigation element returned by the above selector.
For instance:$('ul#nav').slideUp('fast'); When using pure HTML code as its parameter,
$()will create the node (DOM element). That node can, again, be used with any of jQuery's methods.
For instance:$("<li>Sign Off</li>").appendTo("ul#nav");
