你试过吗?
它有用吗?
这是
图片[ ig] .onload = preload_imgs;
我不明白。
//开始索引
var ig = 0;
//数字最大图像
var ig_max = 7;
函数preload_imgs()
{
if(ig< ig_max)
{
//这是一个了不起的新形象!
图片[ig] =新图片();
图片[ig] .onload = preload_imgs;
图片[ig] .src =" pic" ; + ig +" .jpg";
ig ++;
}
}

这个例子中有一个错误!
//开始索引
var ig = 0;
//数字最大图像
var ig_max = 7;
函数preload_imgs()
{
if(ig< ig_max)
{
//何!多么奇妙的新形象!
picture [ig] = new Image();
//在这个新图像上加载(存储在缓存中)
//启动函数:preload_imgs()
//(注意:没有括号!)
picture [ig] .onload = preload_imgs;
//也许获得这个新形象的路径
//会有所帮助吗?
picture [ig] .src =" ; PIC" + ig +" .jpg";
//增加指数
ig ++;
}
//功能结束
//如果需要,是时候重新启动它
//仅在图像加载完成时触发
//与body标签中的'onload'完全相同
}
//达到最大索引时
//函数preload_imgs()的循环停止
//在javascript readind期间启动预编码图像
preload_imgs();

它是
图片[ig] .onload = preload_imgs;
我不明白。
有一个这个例子中的错误!
//起始索引
var ig = 0;
//数字最大图像
var ig_max = 7;
函数preload_imgs()
{
if(ig< ig_max)
//
图片[ig] =新图片();
//在这个新图片上加载(存储在缓存中)
//启动功能:preload_imgs( )
//(注意:没有括号!)
图片[ig] .onload = preload_imgs;
//也许获取这个新图像的路径
//会有一些帮助吗?
picture [ig] .src =" pic" + ig +" .jpg";
//增加索引
ig ++;
}
//功能结束
//它''如果需要,重新启动它的时间
//仅在图像加载完成时才会触发
//与正文标签中的onload完全相同
}
//当达到最大索引时
//循环函数preload_imgs()停止
//在javascript readind期间启动预编码图像
preload_imgs();
Hello,
Can someone please explain how this preload images function works?
It is the
picture[ig].onload = preload_imgs;
which I don''t understand.
Thanks
Geoff
var ig = 0;
function preload_imgs()
{
picture[ig] = new Image();
picture[ig].onload = preload_imgs;
picture[ig].src = "pic" + ig + ".jpg";
ig++;
}
preload_imgs();

There was an error in this example !
// starting index
var ig = 0;
// number max images
var ig_max = 7;
function preload_imgs()
{
if(ig < ig_max)
{
// Ho! What marvelous new image !
picture[ig] = new Image();
// on this new image loaded (stored in cache)
// launch function : preload_imgs()
// (notice : NO parenthesis !)
picture[ig].onload = preload_imgs;
// perhaps path to get this new image
// would be of some help ?
picture[ig].src = "pic" + ig + ".jpg";
// increase index
ig++;
}
// end of function
// it''s time to re-launch it if needed

}
// when max index is reached
