What is the difference between the JQuery object from the usual DOM element?




Explain popular. Links – slippery topic. I never opened to me completely.
What is the difference:

this - element DOM
$ (this) - JQuery object

In JS there are objects, all sorts of different. The $ () function returns the jQuery object, it’s just a JS object with some kind of methods and properties (specified in the jQuery library), and the dom object is another object, it has other properties and methods. Simplified jQuery object is similar to the DOM object roughly as a on B in this example:

var $ = (function () {
  el.prototype.elements = [];
  el.prototype.add = FUNCTION (ELEMENT) {
    this.Elements.Push (Element);
    Return this;
    RETURN NEW EL (). Add (Element);
}) ();
var a = document.getelementByid ('test');
var b = $ (a);
Console.log (A, B);

(i.e. not at all)

Language One – JavaScript, EVENING This is only one. This indicates the call context.

When you write $ (this), the f-ya jQuert.fn.init is called, it is very scary, but in the end returns Normal jQuery object . Those item points to a code, and jQuery object has the properties of Length and Context.

Answer 3

this - pure js
$ (this) - jQuery

For example, if you use this to function, then the jQuery chain of functions will not work. A chain of functions of pure js

will work
