PerformanceElementTiming.id

The id read-only property of the PerformanceElementTiming interface returns the id of the associated element.

Syntax

var id = PerformanceElementTiming.id;

Value

Examples

In this example calling entry.id will log to the console myImage, this being the id of the image element.

<img src="image.jpg" alt="a nice image" elementtiming="big-image" id="myImage">
const observer = new PerformanceObserver((list) => {
  let entries = list.getEntries().forEach(function (entry) {
    if (entry.identifier === "big-image") {
      console.log(entry.id);
    }
  });
});
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.
