jQuery animate backgroundColor: Handling Invalid Property Error
When attempting to animate a change in backgroundColor using jQuery on mouseover, you may encounter an "Invalid Property" error, despite having the correct syntax. This is because jQuery does not natively handle color animations.
Solution: Using a jQuery Color Plugin
To resolve this issue, you can utilize a jQuery color plugin, such as the one provided in the answer. The plugin extends jQuery's animation functionality to handle color transformations, including backgroundColor.
Benefits of Using the Plugin
- Lightweight, only adding a few kilobytes to your codebase
- Minimal overhead, making it highly performant
- Compatibility with major browsers, including Safari
Usage
To use the plugin, include the following code in your page:
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-color/2.2.6/jquery.color.min.js"></script>
Then, you can animate backgroundColor as follows:
$(".usercontent").mouseover(function() {
$(this).animate({
backgroundColor: "olive"
}, "slow");
});
Custom Minification
If you prefer to create your own minified version of the plugin, you can use online compressors like JSCompress or Closure Compiler. The result should be similar to the one provided in the answer.
