To create a custom attribute, replace * with a lowercase string, such as data-id, data-status, or data-location.
A custom data-title attribute on a <figure>.
The attribute value is not visible, but it is readable by JavaScript.
<figure data-title="San Giorgio">
<img src="/img/html/sangiorgio.jpg">
</figure>
The data-* attribute allows you to add custom attributes to a <figure> element.
The * part is replaced with a lowercase string, such as data-id, data-cost, or data-location.
An <figure> element can have any number of data-* attributes, each with their own name.
These attributes usually store additional data about the figure (e.g. id, options, variations, etc.).
Using data-* attributes reduces the need for Ajax requests to the server.
Note: The data-* attribute does not change the appearance of the figure tag in any way.
<figure data-*="value">
Note: The * can be any string, such as data-id, data-cost, data-supplier, etc.
| Value | Description |
|---|---|
| value | A string value. Can be numeric, alphanumeric, JSON, etc. |
A custom data-artist attribute on a <figure> element.
Clicking the button will display the artist value.
<figure id="myfigure" data-artist="Claude Monet">
<img src="/img/html/sangiorgio.jpg">
</figure>
<br/>
<button onclick="show();">Show data</button>
<script>
let show = () => {
let element = document.getElementById("myfigure");
alert("Artist = " + element.getAttribute('data-artist'));
}
</script>
The <figure> tag has a custom data-artist attribute.
The data-artist atttribute holds the figure artist.
Clicks are handled by the onclick event.
Onclick invokes a JavaScript function that extracts and displays the figure artist in an alert box.
Note: Notice how the title displays immediately without server call.
