我想检索可以设置为dom对象的所有可用键/样式的列表：CSSStyleDeclaration对象。如果我在chrome中运行此代码行
console.log(Object.keys(document.querySelector('.class1').style));
我得到了预期的结果：
(517) ["alignContent", "alignItems", "alignSelf", "alignmentBaseline", "all", "animation", "animationDelay", "animationDirection", "animationDuration", "animationFillMode", "animationIterationCount", "animationName", "animationPlayState", "animationTimingFunction", "backdropFilter", "backfaceVisibility", "background", "backgroundAttachment", "backgroundBlendMode", "backgroundClip", "backgroundColor", "backgroundImage", "backgroundOrigin", "backgroundPosition", "backgroundPositionX", "backgroundPositionY", "backgroundRepeat", "backgroundRepeatX", "backgroundRepeatY", "backgroundSize", "baselineShift", "blockSize", "border", "borderBlockEnd", "borderBlockEndColor", "borderBlockEndStyle", "borderBlockEndWidth", "borderBlockStart", "borderBlockStartColor", "borderBlockStartStyle", "borderBlockStartWidth", "borderBottom", "borderBottomColor", "borderBottomLeftRadius", "borderBottomRightRadius", "borderBottomStyle", "borderBottomWidth", "borderCollapse", "borderColor", "borderImage", "borderImageOutset", "borderImageRepeat", "borderImageSlice", "borderImageSource", "borderImageWidth", "borderInlineEnd", "borderInlineEndColor", "borderInlineEndStyle", "borderInlineEndWidth", "borderInlineStart", "borderInlineStartColor", "borderInlineStartStyle", "borderInlineStartWidth", "borderLeft", "borderLeftColor", "borderLeftStyle", "borderLeftWidth", "borderRadius", "borderRight", "borderRightColor", "borderRightStyle", "borderRightWidth", "borderSpacing", "borderStyle", "borderTop", "borderTopColor", "borderTopLeftRadius", "borderTopRightRadius", "borderTopStyle", "borderTopWidth", "borderWidth", "bottom", "boxShadow", "boxSizing", "breakAfter", "breakBefore", "breakInside", "bufferedRendering", "captionSide", "caretColor", "clear", "clip", "clipPath", "clipRule", "color", "colorInterpolation", "colorInterpolationFilters", "colorRendering", "columnCount", "columnFill", …]
但是在firefox中，我得到了一个空数组，而在Edge中，我得到了只有一项的数组
[object Array]: ["WebkitAnimation"]
0: "WebkitAnimation"
length: 1
我的单行代码怎么了？
