HTMLElement: error event - Web APIs

The error event is fired on an element when a resource failed to load, or can't be used. For example, if a script has an execution error or an image can't be found or is invalid.

This event is not cancelable and does not bubble.

Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener("error", (event) => { })

onerror = (event) => { }

The event object is a UIEvent instance if it was generated from a user interface element, or an Event instance otherwise.

<div class="controls">
  <button id="img-error" type="button">Generate image error</button>
  <img class="bad-img" />
</div>

<div class="event-log">
  <label for="eventLog">Event log:</label>
  <textarea
    readonly
    class="event-log-contents"
    rows="8"
    cols="30"
    id="eventLog"></textarea>
</div>

body {
  display: grid;
  grid-template-areas: "control log";
}

.controls {
  grid-area: control;
  display: flex;
  align-items: center;
  justify-content: center;
}

.event-log {
  grid-area: log;
}

.event-log-contents {
  resize: none;
}

button {
  display: block;
}

button {
  height: 2rem;
  margin: 0.5rem;
}

img {
  width: 0;
  height: 0;
}

const log = document.querySelector(".event-log-contents");

const badImg = document.querySelector(".bad-img");
badImg.addEventListener("error", (event) => {
  log.textContent += `${event.type}: Loading image\n`;
  console.log(event);
});

const imgError = document.querySelector("#img-error");
imgError.addEventListener("click", () => {
  badImg.setAttribute("src", "i-dont-exist");
});
