What?

Dizzle turns CSS selectors into functions that tests if elements match them. When searching for elements, testing is executed "from the top", similar to how browsers execute CSS selectors.

Features:

• Full implementation of CSS3 & CSS4 selectors
• Partial implementation of jQuery extensions
• Pretty good performance

Usage

Get Dizzle From jsDelivr and use it like this:

<script src="https://cdn.jsdelivr.net/npm/dizzle/dist/dizzle.umd.min.js"></script>
<script>
  var divs = dizzle('div');
  console.log(divs);
</script>

Dizzle is also available through npm as the dizzle package:

npm install --save dizzle

That you can then use like this:

import dizzle from "dizzle";

dizzle.find('div.myelement');

Documentation

Finding Elements

/**
 * Search For h2 elements inside div in whole document
 */
console.log(dizzle('div > h2'));

/**
 * Fetches All H2 Elements in document
 * and loops into results and find span element in each h2 element
 */
var $h2 = dizzle('h2');
$h2.forEach(function(element){
    console.log(dizzle('span',element));
});

IS / Match Element Pseudo

/**
 * Fetches All H2 Elements in document
 * and loops into results and find span element in each h2 element
 */
var $h2 = dizzle('h2');
$h2.forEach(function(element){
   
    if(dizzle.is(':visible',element)){
        // your code if h2 is visible 
    }
});

Element Filter

/**
 * Filter All Visible H2 tags
 */
var visibleH2 = dizzle.filter(':visible',dizzle('h2'));

Custom Adapter Support

const customAdapter = {
	attr: function( elem, attrName ) {
		if( 'custom-Name' === attrName ) {
			return elem.getAttribute('customName');
		}
		return elem.getAttribute( attrName );
	}
};

const attr = dizzle('[custom-Name="Yes"]',null,customAdapter)

Custom Adapter Functions

A custom adapter must implement the following functions:

isTag, getChildren, getParent, attr, getSiblings, getTagName

Please check src/adapter.js for more information Custom adapters can be passed for all the below functions

/**
  * @param selector String
  * @param context Parent Element / Root
  * @param adapter Custom Adapter Function
  */
dizzle( selector, context, adapter );

/**
  * @param selector String
  * @param elem Single Element Object
  * @param adapter Custom Adapter Function
  */
dizzle.is( selector, elem, adapter )

/**
  * @param selector String
  * @param elems Array of elements
  * @param adapter Custom Adapter Function
  */
dizzle.filter( selector, elems, adapter )

dizzle('div.copyright > p.content + span.year');

Sibling ~
