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.
- Full implementation of CSS3 & CSS4 selectors
- Partial implementation of jQuery extensions
- Pretty good performance
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');/**
* 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));
});/**
* 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
}
});/**
* Filter All Visible H2 tags
*/
var visibleH2 = dizzle.filter(':visible',dizzle('h2'));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)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
*/

The child selector selects all elements that are the children of a specified element.
dizzle('div > p > span');The adjacent sibling selector selects all elements that are the adjacent siblings of a specified element.
dizzle('div.copyright > p.content + span.year');The general sibling selector selects all elements that are siblings of a specified element.
dizzle('p ~ span');The descendant selector matches all elements that are descendants of a specified element.
dizzle('div p span');All notable changes to this project will be documented in this file.
