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);The above is the detailed content of Why Does My JavaScript `animate()` Function Break in Chrome's Web Animations?. For more information, please follow other related articles on the PHP Chinese website!

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
