What does this mean in jquery

This article will explain in detail what this means in jquery. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

This in jquery stands for "current object", this represents the current element in html, uses the "$(this)" statement to turn the html element into a jquery object, and then uses the jquery method to process the current object, and the syntax is "$(this) .jQuery method name ();".

The operating environment of this tutorial: windows10 system, jquery3.2.1 version, Dell G3 computer.

This is a dom object, to put it bluntly, the tags in html. $(this) changes the dom object to a JQuery object, so that you can then use the JQuery method to deal with the Dom object.

Let's first look at the symbol $() in JQuery, which is actually equivalent to JQuery () in JQuery, that is, $(this) = jquery (); that is, it returns a jquery object. So, when you alert ($('# id')); in a web page, a [object Object] pops up, the object object, that is, the jquery object.

Examples are as follows:

$(document) .ready (function () {$("p") .click (function () {$(this). Hide (); / / $(this) is within the method click, where the $(this) represents the object $("p") that currently calls the click method, that is, the current object, the object that is currently calling the method};})
