The DOM represents a document with a logical tree. Each branch of the tree ends in a node, and each node contains objects. DOM methods allow programmatic access to the tree; with them one can change the structure, style or content of a document. [2] Nodes can have event handlers (also known as event listeners) attached to them. Once an event is ...
Event bubbling is a type of DOM event propagation [1] where the event first triggers on the innermost target element, and then successively triggers on the ancestors (parents) of the target element in the same nesting hierarchy till it reaches the outermost DOM element or document object [2] (Provided the handler is initialized).
To prevent an event from bubbling, developers must call the stopPropagation() method of the event object. To prevent the default action of the event to be called, developers must call the preventDefault() method of the event object. The main difference from the traditional model is that multiple event handlers can be registered for the same event.
It is part of a larger collection of objects that the browser makes use of. This collection of browser objects is collectively known as the Browser Object Model, or BOM. [3] The top level of the hierarchy is the window object, which contains the information about the window displaying the document. Some of its fields are objects themselves that ...

The DOM API is the foundation of DHTML, providing a structured interface that allows access and manipulation of virtually anything in the document.
A DOM node can be selected from the tree structure, or by clicking on the browser chrome.

In addition, Carlson said if Trump lowers the Child Tax Credit from its current level of $2,000, families will feel the pinch, especially those with multiple children.
For example, the Document Object Model (DOM) is a collection of objects that represent a page in a web browser, used by script programs to examine and dynamically change the page. There is a Microsoft Excel object model [1] for controlling Microsoft Excel from another program, and the ASCOM Telescope Driver is an object model for controlling an ...
