HTMLImageElement.currentSrc

The read-only HTMLImageElement property currentSrc indicates the URL of the image which is currently presented in the <img> element it represents.

Syntax

let currentSource = htmlImageElement.currentSrc;

Value

A USVString indicating the full URL of the image currently visible in the <img> element represented by the HTMLImageElement. This is useful when you provide multiple image options using the sizes and/or HTMLImageElement.srcset properties. currentSrc lets you determine which image from the set of provided images was selected by the browser.

Example

In this example, two different sizes are provided for an image of a clock. One is 200px wide and the other is 400px wide. The sizes attribute is provided to indicate that the image should be drawn at 50% of the document width if the viewport is under 400px wide; otherwise, the image is drawn at 90% width of the document.

HTML

 <img src="/files/16797/clock-demo-400px.png"
      alt="Clock"
      srcset="/files/16864/clock-demo-200px.png 200w, /files/16797/clock-demo-400px.png 400w"
      sizes="(max-width: 400px) 50%, 90%">

JavaScript

var clockImage = document.querySelector("img");
let p = document.createElement("p");

if (!clockImage.currentSrc.endsWith("200px.png")) {
  p.innerText = "Using the 200px image.";
} else {
  p.innerText = "Using the 400px image!";
}
document.body.appendChild(p);
