/** * @class Ext.dom.Query * @alternateClassName Ext.DomQuery * @alternateClassName Ext.core.DomQuery * @singleton * * Provides high performance selector/xpath processing by compiling queries into reusable functions. New pseudo classes * and matchers can be plugged. It works on HTML and XML documents (if a content node is passed in). * * DomQuery supports most of the [CSS3 selectors spec][1], along with some custom selectors and basic XPath. * * All selectors, attribute filters and pseudos below can be combined infinitely in any order. For example * `div.foo:nth-child(odd)[@foo=bar].bar:first` would be a perfectly valid selector. Node filters are processed * in the order in which they appear, which allows you to optimize your queries for your document structure. * * ## Simple Selectors * * For performance reasons, some query methods accept selectors that are termed as **simple selectors**. A simple * selector is a selector that does not include contextual information about any parent/sibling elements. * * Some examples of valid simple selectors: * * var simple = '.foo'; // Only asking for the class name on the element * var simple = 'div.bar'; // Only asking for the tag/class name on the element * var simple = '[href];' // Asking for an attribute on the element. * var simple = ':not(.foo)'; // Only asking for the non-matches against the class name * var simple = 'span:first-child'; // Doesn't require any contextual information about the parent node * * Simple examples of invalid simple selectors: * * var notSimple = 'div.foo div.bar'; // Requires matching a parent node by class name * var notSimple = 'span + div'; // Requires matching a sibling by tag name * * ## Element Selectors: * * - **`*`** any element * - **`E`** an element with the tag E * - **`E F`** All descendent elements of E that have the tag F * - **`E > F`** or **E/F** all direct children elements of E that have the tag F * - **`E + F`** all elements with the tag F that are immediately preceded by an element with the tag E * - **`E ~ F`** all elements with the tag F that are preceded by a sibling element with the tag E * * ## Attribute Selectors: * * The use of `@` and quotes are optional. For example, `div[@foo='bar']` is also a valid attribute selector. * * - **`E[foo]`** has an attribute "foo" * - **`E[foo=bar]`** has an attribute "foo" that equals "bar" * - **`E[foo^=bar]`** has an attribute "foo" that starts with "bar" * - **`E[foo$=bar]`** has an attribute "foo" that ends with "bar" * - **`E[foo*=bar]`** has an attribute "foo" that contains the substring "bar" * - **`E[foo%=2]`** has an attribute "foo" that is evenly divisible by 2 * - **`E[foo!=bar]`** attribute "foo" does not equal "bar" * * ## Pseudo Classes: * * - **`E:first-child`** E is the first child of its parent * - **`E:last-child`** E is the last child of its parent * - **`E:nth-child(_n_)`** E is the _n_th child of its parent (1 based as per the spec) * - **`E:nth-child(odd)`** E is an odd child of its parent * - **`E:nth-child(even)`** E is an even child of its parent * - **`E:only-child`** E is the only child of its parent * - **`E:checked`** E is an element that is has a checked attribute that is true (e.g. a radio or checkbox) * - **`E:first`** the first E in the resultset * - **`E:last`** the last E in the resultset * - **`E:nth(_n_)`** the _n_th E in the resultset (1 based) * - **`E:odd`** shortcut for :nth-child(odd) * - **`E:even`** shortcut for :nth-child(even) * - **`E:contains(foo)`** E's innerHTML contains the substring "foo" * - **`E:nodeValue(foo)`** E contains a textNode with a nodeValue that equals "foo" * - **`E:not(S)`** an E element that does not match simple selector S * - **`E:has(S)`** an E element that has a descendent that matches simple selector S * - **`E:next(S)`** an E element whose next sibling matches simple selector S * - **`E:prev(S)`** an E element whose previous sibling matches simple selector S * - **`E:any(S1|S2|S2)`** an E element which matches any of the simple selectors S1, S2 or S3 * - **`E:visible(true)`** an E element which is deeply visible according to {@link Ext.dom.Element#isVisible} * * ## CSS Value Selectors: * * - **`E{display=none}`** css value "display" that equals "none" * - **`E{display^=none}`** css value "display" that starts with "none" * - **`E{display$=none}`** css value "display" that ends with "none" * - **`E{display*=none}`** css value "display" that contains the substring "none" * - **`E{display%=2}`** css value "display" that is evenly divisible by 2 * - **`E{display!=none}`** css value "display" that does not equal "none" * * ## XML Namespaces: * - **`ns|E`** an element with tag E and namespace prefix ns * * [1]: http://www.w3.org/TR/2005/WD-css3-selectors-20051215/#selectors */Ext.define('Ext.dom.Query', function() { var DQ, doc = document, cache, simpleCache, valueCache, useClassList = !!doc.documentElement.classList, useElementPointer = !!doc.documentElement.firstElementChild, useChildrenCollection = (function() { var d = doc.createElement('div'); d.innerHTML = '<!-- -->text<!-- -->'; return d.children && (d.children.length === 0); })(), nonSpace = /\S/, trimRe = /^\s+|\s+$/g, tplRe = /\{(\d+)\}/g, modeRe = /^(\s?[\/>+~]\s?|\s|$)/, tagTokenRe = /^(#)?([\w\-\*\|\\]+)/, nthRe = /(\d*)n\+?(\d*)/, nthRe2 = /\D/, startIdRe = /^\s*#/, // This is for IE MSXML which does not support expandos. // IE runs the same speed using setAttribute, however FF slows way down // and Safari completely fails so they need to continue to use expandos. isIE = window.ActiveXObject ? true : false, key = 30803, longHex = /\\([0-9a-fA-F]{6})/g, shortHex = /\\([0-9a-fA-F]{1,6})\s{0,1}/g, nonHex = /\\([^0-9a-fA-F]{1})/g, escapes = /\\/g, num, hasEscapes, // True if the browser supports the following syntax: // document.getElementsByTagName('namespacePrefix:tagName') supportsColonNsSeparator = (function () { var xmlDoc, xmlString = '<r><a:b xmlns:a="n"></a:b></r>'; if (window.DOMParser) { xmlDoc = (new DOMParser()).parseFromString(xmlString, "application/xml"); } else { xmlDoc = new ActiveXObject("Microsoft.XMLDOM"); xmlDoc.loadXML(xmlString); } return !!xmlDoc.getElementsByTagName('a:b').length; })(), // replaces a long hex regex match group with the appropriate ascii value // $args indicate regex match pos longHexToChar = function($0, $1) { return String.fromCharCode(parseInt($1, 16)); }, // converts a shortHex regex match to the long form shortToLongHex = function($0, $1) { while ($1.length < 6) { $1 = '0' + $1; } return '\\' + $1; }, // converts a single char escape to long escape form charToLongHex = function($0, $1) { num = $1.charCodeAt(0).toString(16); if (num.length === 1) { num = '0' + num; } return '\\0000' + num; }, // Un-escapes an input selector string.
