PHP port of jQuery 2.0
pre-alpha version
I disliked phpQuery so I made a simple 1 to 1 port of jQuery 2.0 Source
It started as a couple of helper functions and grew to what it is now
It is in an unfinished state because otherwise I would have never published it.
Lots of stuff could be broken, so try it first. I provide no warranty what so ever.
Put the classes in /vendor/ThinkHTML/jQuery/ and use the PSR autoloader
$loader = require 'vendor/autoload.php';
require '/path/to/HTML5Parser.php';
require '/path/to/JQuery.php';
require '/path/to/JQueryObject.php';
require '/path/to/SymfonyCSSSelector.php';
SymfonyCSSSelector::import('/vendor/Symfony/Component/CssSelector/');
use ThinkHTML\jQuery\HTML5Parser;
$options = array('default_encoding'=>'utf-8');
$parser = new HTML5Parser($options);
$val = null;
$parser->parse($html, function($document, $jquery) use(&$val){
$val = $jquery('input')->prop('disabled',true)->val();
$nodes_array = $jquery->parseHTML('<div>');
});
You don't have to use HTML5Parser to use the jQuery class
$dom = new \DOMDocument;
$dom->loadHTML('<div></div>');
$jquery = new jQuery($dom);
$jquery('div')->append('<span>Hello world</span>');
starts with < = html
starts with / (or any of the xpath keywords) = xpath
everything else = css3
$jquery('.myclass'); // selects all elements with the class name "myclass" with CSS
$jquery('descendant::*[@id="myid"]'); // selects all elements with the id "myid" with XPath
$jquery('<div></div>'); // creates a div element in the current document (but does not attach it)
$document->getElementsById('myid'); // selects elements with id "myid" with a DOMDocument selector
$options = array(
'encoding'=>'utf-8', // force utf-8 encoding
'default_encoding'=>'utf-8', // set fallback encoding if it is not defined in the document
'data_camel_case'=>true, // convert data-* attributes when using $jquery().data() according to w3c spec
);
$parser = new HTML5Parser($options);
jQuery function in JavaScript
jQuery.each
jQuery Collection function in JavaScript
jQuery().each
###jQuery Collection plugin
attach
<script>
jQuery.fn.color = function(color){
this.css( "color", color );
};
</scrpt>
use
<script>
jQuery(function(){
jQuery('a').color('red');
});
</script>
###PHP jQuery Collection plugin
attach
$parser->extend(function($dom, $jquery){
$jquery->fn->color = function($that, $color){
$that->css( "color", $color);
};
});
use
$parser->parse($html, function($dom, $jquery){
$jquery('a')->color('red');
});
In order to support php5.3 the first argument passed to the jquery collection extension function will be an instance of the current jquery collection object (called $that in the example below).
All the other arguments are passed to the function are passed after $that (as normal)
While the jQuery class extensions do not need $that
$htmldoc = '<!DOCTYPE html><html><head><meta charset="utf-8"></head><body><h1>Error none</h1><p>Page found</p></body></html>';
$parser = new HTML5Parser($htmldoc);
$parser->error(function($err){
// $err is an Exception
});
// Example plugins
$parser->extend(function($dom, $q){
// jQuery fn extension
// http://learn.jquery.com/plugins/basic-plugin-creation/
$q->fn->greenify = function($that) use($q){
$that->css( "color", "green" );
};
$q->fn->showLinkLocation = function($that) use($q){
$that = isset($this)?$this:($q::$instance);
return $that->each(function($i, $el) use($q) {
$q( $el )->append( " (" . $q( $el )->attr( "href" ) . ")" );
});
};
// jQuery class extension
$q->sum = function() use($q){
return array_sum(func_get_args());
};
});
$parser->parse($html, function($document, $jquery){
// $document holds an instance of DOMDocument
// $jquery holds an instance of jQuery
// Run utility functions with $jQuery->parseHTML($data, $context, $keep_scripts);
// Query the DOM with CSS3 and manipulate the selection: $jquery('.class-name')->attr('rel', 'external');
// Query the DOM with XPATH and manipulate the selection: $jquery('descendant::select')->val('');
// Get the <body> content html: $jquery('body')->html();
});
- Works with unicode (was surprisingly hard to achieve)
- Supports working with multiple documents at the same time, even within each others callbacks
HTML5Parser::parse()creates a context for the jquery object to work with
-
Test setting attribute on detached elements
-
Add remaining functions
-
Add it to composer
-
Add unit tests
-
Can't use some forms of xpath when searching within a context, added option to disable css and treat everything as xpath
-
Simplify code by duplicating the functions attached to fn in jquery, for example
$.after($node, $node2); -
$jquery()->filter(); not working properly
-
Implement
$keep_scriptsparam inparseHTML($html, $keep_scripts) -
Make the css_converter customizable
$options = array('css_converter'=>'SymfonyCSSSelector::toXPath'); $parser = new HTML5Parser($options);
