Comparison between native JS and jQuery DOM, jsjquerydom

I. Create element nodes

1.1 native JS creates element nodes


1.2 create an element node using jQuery


2. Create and add text nodes

2.1 native JS creates text nodes

`document.createTextNode("Text Content");

Generally, you can create text nodes and element nodes in combination. For example:

var textEl = document.createTextNode("Hello World.");var pEl = document.createElement("p");pEl.appendChild(textEl);

2.2 create and add a text node using jQuery:

var $p = $('<p>Hello World.</p>');

Iii. Copy nodes

3.1 native JS replication nodes:

var newEl = pEl.cloneNode(true); `

Difference between true and false:

  • True: Clone the entire '<p> Hello World. </p>' node.
  • False: Clone '<p> </p>' only, do not clone the text Hello World .'

3.2 jQuery replication Node

$newEl = $('#pEl').clone(true);

Note:Duplicate 'id' should be avoided when cloning a node

4. Insert nodes

4.1 native JS adds a new subnode to the end of the subnode list


Native JS inserts a new subnode before the existing subnode of the node:

El.insertBefore(newNode, targetNode);

4.2 In jQuery, there are more methods to insert nodes than native JS.

Add content at the end of the child node list of matching elements

$('#El').append('<p>Hello World.</p>');

Add matching elements to the end of the target element subnode list

$('<p>Hello World.</p>').appendTo('#El');

Add content at the beginning of the child node list of the Matching Element

$('#El').prepend('<p>Hello World.</p>');

Add matching elements to the beginning of the target element subnode list

$('<p>Hello World.</p>').prependTo('#El');

Add target content before Matching Element

$('#El').before('<p>Hello World.</p>');

Add the matching element to the target Element

$('<p>Hello World.</p>').insertBefore('#El');

Add target content after Matching Element

$('#El').after('<p>Hello World.</p>');

After adding the matching element to the target Element

$('<p>Hello World.</p>').insertAfter('#El');

5. delete a node

5.1 native JS delete node


5.2 jQuery delete a node


Vi. Replacing nodes

6.1 native JS replacement Node

El.repalceChild(newNode, oldNode);

Note:OldNode must be a real child node of parentEl.

6.2 jQuery replacement Node

$('p').replaceWith('<p>Hello World.</p>');

VII. Set Properties/get Properties

7.1 native JS sets attributes/obtains attributes

imgEl.setAttribute("title", "logo");imgEl.getAttribute("title");checkboxEl.checked = true;checkboxEl.checked;

7.2 jQuery sets/retrieves attributes:

$("#logo").attr({"title": "logo"});$("#logo").attr("title");$("#checkbox").prop({"checked": true});$("#checkbox").prop("checked");
