Why Does My JavaScript `animate()` Function Break in Chrome's Web Animations?

JS Function animate May Break in Chrome Due to Web Animations

This JavaScript code attempts to animate an HTML element named "demo" by changing its position and color. However, it fails to work in Chrome.

function animate() {
  var div = document.getElementById('demo');
  div.style.left = "200px";
  div.style.color = "red";
}

The Problem

In Chrome, the issue lies with the global function animate() being overridden by a newly introduced method on the Element prototype in Web Animations. This means the global function is no longer accessible within the scope of the event handler.

The Solution

To address this problem, consider the following options:

• Rename the Function: Rename animate to avoid conflicts with the prototype method, such as animate__.

function animate__() {
  // ... same code as above ...
}

• Use JavaScript's bind Method: Bind the global animate function to the scope of the event handler.

document.getElementById('demo').onclick = animate.bind(this);

• Use Element's Native animate() Method: Leverage the native animate() method on the target element directly.

document.getElementById('demo').animate([
  { left: "200px" },
  { color: "red" }
], 2000);
