我知道这是你想要的答案,但如果你在某个项目中实际使用这一答案,那么有两点需要注意:

• You are only animating opacity – remember that IE<9 doesn t support this property.
• All current browsers that support opacity also support transitions (Firefox 3.X is the exception, but that s not going to hang around now 4 is out).

因此,在你所希望的所有现有浏览器中开展工作的更清洁的办法,是利用空间安全局建立这种系统。

-webkit-transition:opacity 0.6s ease-in-out;
-moz-transition:opacity 0.6s ease-in-out;
-o-transition:opacity 0.6s ease-in-out;
-ms-transition:opacity 0.6s ease-in-out;
transition:opacity 0.6s ease-in-out;

之后,在您的《联合材料》中,公正改变了不透明性。

this.style.opacity = ".90";

它将按要求进行校正,作为相当大笔的奖金,它将加速一些浏览器的硬件(当前是iOS)。

当你去此行时:

var opacity = this.style.opacity;

。

从一项功能中转来,您需要clearInterval。

function fadeOut(r, s) {
    var self = this;
    if (!self instanceof Element) return false;
    self.style.opacity = ".90";
    var t = setInterval(function() {
        if (!r) r = 500;
        self.style.opacity = self.style.opacity - s;
        if (self.style.opacity == ".0") {
            clearInterval(t);    
        }
    }, r);
};

Also, full opacity is 1 and none is 0. You are reducing it by s each time and s is defined as 5. Since you start by dropping to .9, you probably mean:

 fadeOut.apply(d, [100, .1]);

Your opacity starts at 0.9. Then you subtract 5 from it on every interval. What this means is that the first time the interval runs you will try to set the opacity to the string "-4.1", which will fail to parse as a valid opacity value, so the set will be ignored. And then you go around in circles. Did you mean 0.05 instead of 5? Or s/100 in the callback function?

var d = document.getElementById("box");

function fadeOut(r, s) {
    if (!this instanceof Element) return false;
    this.style.opacity = ".90";
    var opacity = this.style.opacity;
    var t = setInterval(function() {
        if (!r) r = 500;
        opacity = (opacity) - s;
        if (opacity == ".0") return;
    }, r); };

fadeOut.apply(d, [100, 5]);

There are many things wrong with this code.

首先,社会保障局的财产正在扼杀,因此,你的不透明补充线应当是:

opacity = parseInt(opacity) - 0.05 +   ;

平均率变成了星号,然后又增加了负0.05,然后用<代码>+ back。

其次,if (!r) r = 500;应当从匿名职能外界定。

应:

var d = document.getElementById("box");

function fadeOut(fadeScaler, hertz) {
    if (!this instanceof Element) return false;
    hertz = (!hertz) ? 60 : hertz; // Approx 60 hertz refresh rate

    var opacity = this.style.opacity
        opacity = ".9";

    var t = setInterval(
       function() {
         opacity = parseInt(opacity) - fadeScaler +   ;

         if (parseInt(opacity) <= 0) 
           clearInterval(t);
       },
       Math.floor(1000 / hertz)); // 1000 miliseconds / hertz = refresh rate
};

fadeOut.apply(d, [.05]);

更加注意你的法典的成文和风格。 一位立法者是智能代码。

此外,在《欧洲常规武装力量法》中,“不透明”相当于:

this.filters.alpha.opacity=100
