CSS属性更改侦听器的任何建议实现?也许:
thread =
function getValues(){
while(true){
for each CSS property{
if(properties[property] != nil && getValue(property) != properties[property]){alert('change')}
else{properties[property] = getValue(property)}
}
}
}

我认为你正在寻找这个:
document.documentElement.addEventListener('DOMAttrModified', function(e){
if (e.attrName === 'style') {
console.log('prevValue: ' + e.prevValue, 'newValue: ' + e.newValue);
}
}, false);
如果你谷歌,它会出现一堆东西。这看起来很有希望:

不推荐使用DOMAttrModified
等变种事件。请考虑使用MutationObserver。
示例:
<div>use devtools to change the <code>background-color</code> property of this node to <code>red</code></div>
<p>status...</p>
JS:
var observer = new MutationObserver((mutations) => {
mutations.forEach((mutation) => {
if (mutation.target.style.color === 'red') {
document.querySelector('p').textContent = 'success';
}
});
});
var observerConfig = {
attributes: true,
childList: false,
characterData: false,
attributeOldValue: true
};
var targetNode = document.querySelector('div');
observer.observe(targetNode, observerConfig);
