Semalt: Atributos del elemento. Todo lo que necesitas saber

Document Object Model (DOM) es una interfaz de programación de aplicaciones (API) para documentos estructurados XML y HTML. La API define la estructura definitiva de los documentos, cómo acceder a ellos y cómo los raspadores web acceden y raspan documentos a través de la web.

DOM trabaja para recuperar y modificar atributos presentes en elementos HTML. Con Dom, puede acceder a los atributos y estilos de los elementos utilizados en un documento en particular. Con algunas técnicas de raspado, puede recuperar la imagen de fondo del documento de destino.

Nodos de HTML DOM

Cuando se trata de JavaScript, DOM se denomina estándar del World Wide Web Consortium (W3C). Dom se utiliza para definir e ilustrar un estándar para acceder a documentos. El Modelo permite que las secuencias de comandos y los programas se actualicen y accedan a la estructura utilizada para escribir un documento.

Cuando se trata de HTML DOM, todo puede considerarse como un nodo. Por ejemplo:

  • Todos los atributos HTML son nodos de atributo;
  • Los comentarios son nodos de comentarios;
  • Todos los elementos HTML son nodos de elementos;
  • El documento en sí se denomina nodo de documento;

Document Object Model se usa para acceder y manipular elementos dentro de documentos XML y HTML. Los elementos se organizan y gestionan en una estructura de datos (similar a un árbol) que puede atravesarse fácilmente para su navegación y modificación. Puede agregar clases a DIV, cuerpo o elemento HTML usando hojas de estilo en cascada (CSS) o interactuar con los elementos usando JS.

Lo que necesita saber sobre los atributos de la propiedad

Se puede acceder y manipular los nodos utilizando sus respectivos números de índice, donde el índice mínimo es "0". La propiedad de atributos funciona devolviendo una colección detallada de los atributos de un nodo en particular, como el objeto NamedNodeMap. Tenga en cuenta que la indexación numérica lo ayudará a pasar por un atributo de elemento.

Elemento de atributo

La propiedad de atributo de elemento devuelve una colección válida de todos los nodos de atributo que están registrados en un nodo particular. En palabras simples, es un NamedNodeMap. Por lo tanto, carece de métodos de Array. El atributo (un par de cadenas que representan cualquier dato relacionado con el atributo dado) nodos puede diferir dependiendo del navegador utilizado.

En esta publicación, el objeto NamedNodeMap representa la colección no estructurada de nodos de atributo de un elemento específico. No tiene que entrar en pánico en lo que respecta al navegador que ha estado utilizando. El objeto NamedNodeMap y el objeto Attribute son compatibles con los principales navegadores web.

El objeto NamedNodeMap se compone de una propiedad de longitud que puede usar para determinar la cantidad precisa de atributos. Después de identificar el número total de atributos en un documento, recorra los nodos de atributos y extraiga su información de destino. Al recuperar datos de un texto, tenga en cuenta que los atributos HTML también se denominan nodos de atributos que comprenden propiedades para su objeto Atributo.

Para los entusiastas de Internet Explorer, debe tener en cuenta que la propiedad de atributos tiende a devolver una colección detallada de los atributos posibles para un elemento específico. Una vez que se genera un nodo DOM para cualquier elemento HTML dado, muchos de los atributos se relacionan con atributos que llevan los mismos nombres. Al desarrollar un código fuente HTML, puede definir los atributos en sus elementos HTML. Una vez que su navegador analiza su secuencia de comandos, se creará un DOM correspondiente con un nodo similar. El nodo correspondiente se denomina como un objeto.
