背景色不停闪烁的特效

要完成此效果需要两个步骤

第一步：把如下代码加入到%26lt;head%26gt;区域中

%26lt;SCRIPT LANGUAGE=%26quot;JavaScript%26quot;%26gt;

%26lt;!-- Hide from old browsers
var Color= new Array(9);
Color[1] = %26quot;ff%26quot;;
Color[2] = %26quot;ee%26quot;;
Color[3] = %26quot;dd%26quot;;
Color[4] = %26quot;cc%26quot;;
Color[5] = %26quot;bb%26quot;;
Color[6] = %26quot;aa%26quot;;
Color[7] = %26quot;99%26quot;;
Color[8] = %26quot;88%26quot;;
Color[9] = %26quot;77%26quot;;
Color[10] = %26quot;66%26quot;;
Color[11] = %26quot;55%26quot;;
Color[12] = %26quot;44%26quot;;
Color[13] = %26quot;33%26quot;;
Color[14] = %26quot;22%26quot;;
Color[15] = %26quot;11%26quot;;
Color[16] = %26quot;00%26quot;;
/* Do not display text on a fading background. Instead, let it
fade in and out once or twice, then load a new page. */
function fadeIn(where) {
if (where %26gt;= 1) {
document.bgColor=%26quot;#%26quot; + Color[where] +%26quot;0000%26quot;;
where -= 1;
setTimeout(%26quot;fadeIn(%26quot;+where+%26quot;)%26quot;, 15);
} else {
setTimeout('fadeOut(1)', 15);
}
}
function fadeOut(where) {
if (where %26lt;=16) {
document.bgColor=%26quot;#%26quot; + Color[where] +%26quot;0000%26quot;;
where += 1;
setTimeout(%26quot;fadeOut(%26quot;+where+%26quot;)%26quot;, 15)
} else {
setTimeout(%26quot;fadeIn(16)%26quot;, 15);
// window.location.href=%26quot;http://www.jojoo.net/%26quot;;
}
}
// Unhide --%26gt;
%26lt;/SCRIPT%26gt;


第二步：把“onLoad=%26quot;fadeIn(16)%26quot;”加在%26lt;body%26gt;标记里
例如：%26lt;body onLoad=%26quot;fadeIn(16)%26quot;%26gt;
