Tutorials - HTML Table Add Row - innerHTML vs. DOM vs. cloneNode - mredkj.com
Overview The purpose of this page is to provide some simple examples of adding rows to an existing table. All the examples do the same basic thing, but in different ways. When deciding which technique to use, you may want to refer to some discussion others have had on the topic of how to dynamically manipulate a web page. In March 2006, Chris Heilmann wrote From DHTML to DOM scripting , which examines many aspects of old DHTML techniques versus DOM scripting. This led to a lot of chatter around the web, especially on the topic of innerHTML vs.W3C DOM
As we've discussed previously, DOM (Document Object Model) is the way to access things on the screen. And, as we've examined, there are numerous browser-inconsistancies from accessing layers with document.layers to document.all to document.getElementById . To standardize the DOM, W3C created a future more standard Document Object Model, which is in place in some current browsers, at least partly, and will be in place (it should be) in future browsers. Currently, IE 5 supports most of the features we'll review, and NS 6 should support all of them, but both can present some problems.From Semantic Web Standards Overview RDF is a standard model for data interchange on the Web. RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed. RDF extends the linking structure of the Web to use URIs to name the relationship between things as well as the two ends of the link (this is usually referred to as a “triple”).
