The element
read-only property of the PerformanceElementTiming
interface returns an Element
which is a literal representation of the associated element.
Syntax
var element = PerformanceElementTiming.element;
Value
An Element
.
Examples
In this example calling entry.element
will log to the console <img src="image.jpg" alt="a nice image" elementtiming="big-image">
.
<img src="image.jpg" alt="a nice image" elementtiming="big-image">
const observer = new PerformanceObserver((list) => {
let entries = list.getEntries().forEach(function (entry) {
if (entry.identifier === "big-image") {
console.log(entry.element);
}
});
});
observer.observe({ entryTypes: ["element"] });
This example uses the PerformanceObserver
interface to create a list of performance measurement events. In our case we observe the PerformanceEntry.entrytype
element
in order to use the PerformanceElementTiming
interface.
