Create Element Js
Examples
The following code example shows how to examine an arbitrary HTML document and derive a string describing the HTML elements, with indentation and level numbers used to indicate how deeply nested the elements are in the document. This code example requires that your application hosts a WebBrowser control named WebBrowser1.
Remarks
HtmlElement represents any possible type of element in an HTML document, such as BODY, TABLE, and FORM, among others. The class exposes the most common properties you can expect to find on all elements.
Most elements can have child elements: other HTML elements that are placed underneath them. Use the CanHaveChildren property to test whether a given element has children, and the Children collection to iterate through them. The Parent property returns the HtmlElement in which the current element is nested.
You often need access to attributes, properties, and methods on the underlying element that are not directly exposed by HtmlElement, such as the SRC attribute on an IMG element or the Submit method on a FORM. The GetAttribute and SetAttribute methods enable you to retrieve and alter any attribute or property on a specific element, while InvokeMember provides access to any methods not exposed in the managed Document Object Model (DOM). If your application has unmanaged code permission, you can also access unexposed properties and methods with the DomElement attribute.
Use the TagName property to test whether an element is of a specific type.
Any HTML document can be modified at run time. You can create new HtmlElement objects with the CreateElement method of HtmlDocument, and add them to another element using the AppendChild or InsertAdjacentElement methods. You can also create the elements as HTML tags and assign them to an existing element's InnerHtml property.
