SVGAElement: interestForElement property

Value

An Element object instance, or null if the associated <a> element does not have a target element set.

Examples

Basic interestForElement usage

In this example, we use an SVG <a> element's interestForElement property to set its target element and then retrieve the target element's tagName. The tagName is then included in the <a> element's text content.

HTML

The markup contains an SVG <a> element with a <text> element, and the link text is included within the <text> element. There's also an HTML <div> element. We turn the <div> element into a popover by setting the popover attribute on it.

<svg>
  <a href="#">
    <text x="90" y="20" text-anchor="middle">A link</text>
  </a>
</svg>
<div id="mypopover" popover>I am a <code>&lt;div&gt;</code> element.</div>

svg {
  width: 200px;
  height: 100px;
}

svg a text {
  fill: blue;
  text-decoration: underline;
}

JavaScript

We get references to the <a>, <text>, and <div> elements in script. We then create the interest invoker-target relationship between the <a> and the <div> by setting the <a> element's interestForElement property equal to a reference to the <div>. We then update the <text> content to display the target element's tagName, retrieved via invoker.interestForElement.tagName.

const invoker = document.querySelector("a");
const invokerText = document.querySelector("text");
const popover = document.querySelector("div");

invoker.interestForElement = popover;

invokerText.textContent = `My target is a ${invoker.interestForElement.tagName} element`;

Result

The example renders like this:

Try showing interest in the link (for example, by hovering or focusing it) to make the <div> appear.
