GET – Requests data from a specified resource
POST – Submits data to be processed to a specified resource
In computing, POST is a request method supported by the HTTP protocol used by the World Wide Web. By design, the POST request method requests that a web server accept the data enclosed in the body of the request message, most likely for storing it. It is often used when uploading a file or when submitting a completed web form.

Note that the query string (name/value pairs) is sent in the HTTP message body of a POST request:
POST /test/demo_form.php HTTP/1.1
Host: w3schools.com
name1=value1&name2=value2
POST requests are never cached
POST requests do not remain in the browser history
POST requests cannot be bookmarked
POST requests have no restrictions on data length

The jQuery syntax is tailor-made for selecting HTML elements and performing some action on the element(s).
Basic syntax is: $(selector).action()
1) A $ sign to define/access jQuery
2) A (selector) to “query (or find)” HTML elements
3) A jQuery action() to be performed on the element(s)

$(this).hide() – hides the current element.
$(“p”).hide() – hides all <p> elements.
$(“.test”).hide() – hides all elements with class=”test”.
$(“#test”).hide() – hides the element with id=”test”.

$ is just a shortcut for jQuery. The idea is that everything is done with the one global symbol (since the global namespaces is ridiculously crowded), jQuery, but you can use $ (because it’s shorter) if you like.

// These are the same barring your using noConflict (more below)
var divs = $(“div”); // Find all divs
var divs = jQuery(“div”); // Also find all divs, because
console.log($ === jQuery); // “true”

Code 1:
$(‘#row DIV’).mouseover(function(){
$(‘#row DIV’).addClass(‘testing’);
});
Code 2:
$(‘.row div’).mouseover(function(){
$(this).addClass(‘testing’);
});

The hash (#) specifies to select elements by their ID’s
The dot (.) specifies to select elements by their classname
$(‘.row’) will select any element with class=”row”
$(‘#row’) will select the element with id=row
