我试图在鼠标悬停时使用jQuery动画改变backgroundColor。

我检查了一些例子,我似乎有它是正确的,它与其他属性,如fontSize,但与backgroundColor我得到和“无效属性”js错误。 我正在使用的元素是div。

$(".usercontent").mouseover(function() {
    $(this).animate({ backgroundColor: "olive" }, "slow");
});

什么好主意吗?

我喜欢使用delay()来完成这个任务,这里有一个例子:

jQuery(element).animate({ backgroundColor: "#FCFCD8" },1).delay(1000).animate({ backgroundColor: "#EFEAEA" }, 1500);

这可以由函数调用,“element”是元素类/名称/等。元素将立即以#FCFCD8背景出现,稍等片刻,然后淡出为#EFEAEA。

ColorBlend插件完全是你想要的

这里是我的高亮代码

$("#container").colorBlend([{
    colorList:["white",  "yellow"], 
    param:"background-color",
    cycles: 1,
    duration: 500
}]);

这些天jQuery颜色插件支持以下命名颜色:

aqua:[0,255,255],
azure:[240,255,255],
beige:[245,245,220],
black:[0,0,0],
blue:[0,0,255],

color插件只有4kb,比UI库便宜多了。当然,你会想要使用一个像样的版本的插件,而不是那些bug百出的老东西,不能处理Safari和崩溃时,过渡太快。由于不提供缩小版本,您可能喜欢测试各种压缩器,并制作自己的最小版本。在这种情况下,YUI得到了最好的压缩,只需要2317字节,因为它是如此之小-下面是:

(function (d) {
    d.each(["backgroundColor", "borderBottomColor", "borderLeftColor", "borderRightColor", "borderTopColor", "color", "outlineColor"], function (f, e) {
        d.fx.step[e] = function (g) {
            if (!g.colorInit) {
                g.start = c(g.elem, e);
                g.end = b(g.end);
                g.colorInit = true
            }
            g.elem.style[e] = "rgb(" + [Math.max(Math.min(parseInt((g.pos * (g.end[0] - g.start[0])) + g.start[0]), 255), 0), Math.max(Math.min(parseInt((g.pos * (g.end[1] - g.start[1])) + g.start[1]), 255), 0), Math.max(Math.min(parseInt((g.pos * (g.end[2] - g.start[2])) + g.start[2]), 255), 0)].join(",") + ")"
        }
    });

    function b(f) {
        var e;
        if (f && f.constructor == Array && f.length == 3) {
            return f
        }
        if (e = /rgb\(\s*([0-9]{1,3})\s*,\s*([0-9]{1,3})\s*,\s*([0-9]{1,3})\s*\)/.exec(f)) {
            return [parseInt(e[1]), parseInt(e[2]), parseInt(e[3])]
        }
        if (e = /rgb\(\s*([0-9]+(?:\.[0-9]+)?)\%\s*,\s*([0-9]+(?:\.[0-9]+)?)\%\s*,\s*([0-9]+(?:\.[0-9]+)?)\%\s*\)/.exec(f)) {
            return [parseFloat(e[1]) * 2.55, parseFloat(e[2]) * 2.55, parseFloat(e[3]) * 2.55]
        }
        if (e = /#([a-fA-F0-9]{2})([a-fA-F0-9]{2})([a-fA-F0-9]{2})/.exec(f)) {
