Class goog.dom.DomHelper

Create an instance of a DOM helper with a new document object.

Instance Method Summary
	`createDom(string tagName, (Object\|null\|string=) opt_attributes, (goog.dom.Appendable\|null\|undefined) var_args) ⇒ !Element` Returns a dom node with a set of attributes. This function accepts varargs for subsequent nodes to be added. Subsequent nodes will be added to the first node as childNodes. So: `createDom('div', null, createDom('p'), createDom('p'));` would return a div with two child paragraphs An easy way to move all child nodes of an existing element to a new parent element is: `createDom('div', null, oldElement.childNodes);` which will remove all child nodes from the old element and add them as child nodes of the new DIV.
	`createElement(string name) ⇒ !Element` Creates a new element.
	`createTable(number rows, number columns, boolean= opt_fillWithNbsp) ⇒ !Element` Create a table.
	`createTextNode(string content) ⇒ !Text` Creates a new text node.
	`getCompatMode() ⇒ string` Returns the compatMode of the document.
	`getDocument() ⇒ !Document` Gets the document object being used by the dom library.
	`getDocumentHeight() ⇒ number` Calculates the height of the document.
	`getDocumentScroll() ⇒ !goog.math.Coordinate` Gets the document scroll distance as a coordinate object.
	`getDocumentScrollElement() ⇒ ?Element` Gets the document scroll element.
	`getElement((Element\|null\|string) element) ⇒ ?Element` Alias for {@code getElementById}. If a DOM node is passed in then we just return that.
	`getElementByClass(string className, (Document\|Element\|null=) opt_el) ⇒ ?Element` Returns the first element we find matching the provided class name.
	`getElementsByClass(string className, (Document\|Element\|null=) opt_el) ⇒ {length: number}` Returns an array of all the elements with the provided className.
	`getElementsByTagNameAndClass(?string= opt_tag, ?string= opt_class, (Document\|Element\|null=) opt_el) ⇒ {length: number}` Looks up elements by both tag and class name, using browser native functions ({@code querySelectorAll}, {@code getElementsByTagName} or {@code getElementsByClassName}) where possible. The returned array is a live NodeList or a static list depending on the code path taken.
	`getViewportSize(?Window= opt_window) ⇒ !goog.math.Size` Gets the dimensions of the viewport.
	`getWindow() ⇒ !Window` Gets the window object associated with the document.
	`htmlToDocumentFragment(string htmlString) ⇒ !Node` Converts an HTML string into a node or a document fragment. A single Node is used if the {@code htmlString} only generates a single node. If the {@code htmlString} generates multiple nodes then these are put inside a {@code DocumentFragment}.
	`isCss1CompatMode() ⇒ boolean` Returns true if the browser is in "CSS1-compatible" (standards-compliant) mode, false otherwise.
	`setDocument(!Document document)` Sets the document object.
