Microdata DOM API

Warning: Microdata were implemented in some browsers for a long time. Nowadays, they have been abandoned and removed from all browsers and are therefore deprecated. You can't use them anymore and this document is kept as information only.

js var biography = document.getItems("http://example.org/biography")[0]; alert('Hi there ' + biography.properties['name'][0].textContent + '!');

```js // This sample shows how the getItems() method can be used to obtain a list // of all the top-level microdata items of one type given in the document:

var cats = document.getItems("http://example.com/feline"); ```

```js // This sample gets the first item of type "http://example.net/user" // and then pops up an alert using the "name" property from that item.

var user = document.getItems('http://example.net/user')[0]; alert('Hello ' + user.properties['name'][0].content + '!'); ```

```js // The HTMLPropertiesCollection object, when indexed by name in this way, // actually returns a PropertyNodeList object with all the matching properties. // The PropertyNodeList object can be used to obtain all the values at once // using its values attribute, which returns an array of all the values.

var cat = document.getItems('http://example.org/animals#cat')[0]; var colors = cat.properties['http://example.com/color'].values; var result; if (colors.length == 0) { result = 'Color unknown.'; } else if (colors.length == 1) { result = 'Color: ' + colors[0]; } else { result = 'Colors:'; for (var i = 0; i < colors.length; i += 1) result += ' ' + colors[i]; } ```
