Sample text

Id); } First up, you grab the

with an ID of main and change the background color to red. Next, you grab all the paragraph elements, loop through each one, and set the font size to 2 ems. The last example grabs the tag and then loops through its child nodes and pops an alert with the ID of the element. That last example covers a few tricks. First, all elements are grabbed that have the tag name of body. Your HTML document will have only one. Therefore, you can use [0] to retrieve the first (and only) element from the collection.

For example, getAttribute("class") should work, but because IE simply maps the method to the attribute property, and because class is a reserved word, it doesn’t work. Instead, you have to specify className. com/2007/ 1/11/attribute-nightmare-in-ie. The style Property Each element in the DOM has a style property that enables you to style the elements dynamically. All the CSS properties are available through the style property. display = 'none'; // hides the element from the user JavaScript doesn’t like hyphens in methods or properties, so any hyphenated CSS properties have the hyphen removed and the first letter of the second word capitalized—this format is also known as camel case.

The extension also addresses the need to be backward-compatible with the features of DOM Level 0. Many of these HTMLspecific features share widespread and consistent browser support. • DOM Level 2 adds additional XML- and HTML-specific extensions and adds support for manipulating style information, events, and ranges (handy for doing browser-based WYSIWYG editing). At this level, you start to see a divergence in how these standards are implemented across browsers. Mozilla browsers such as Firefox have stuck very closely to the W3C specification, whereas IE went in a different direction.
