PerformanceElementTiming.url

The url read-only property of the PerformanceElementTiming interface returns the initial URL of the resource request when the element is an image.

Syntax

var url = PerformanceElementTiming.url;

Value

A DOMString which is the initial URL of the resources request for images or 0 for text.

Examples

In this example calling entry.url returns https://example.com/image.jpg.

<img src="https://example.com/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.url);
    }
  });
});
observer.observe({ entryTypes: ["element"] });

Note: 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.
