在我们的网站上,我在html中嵌入了flash builder生成的flash,闪存大小超过2M。由于网络不良,可能需要30秒才能加载闪存。我怎么知道闪存已被浏览器完全加载?

您可以轮询SWF以获取其PercentLoaded
值。
这是一种方法(从learnswfobject.com复制的代码):
function swfLoadEvent(fn){
//Ensure fn is a valid function
if(typeof fn !== "function"){ return false; }
//This timeout ensures we don't try to access PercentLoaded too soon
var initialTimeout = setTimeout(function (){
//Ensure Flash Player's PercentLoaded method is available and returns a value
if(typeof e.ref.PercentLoaded !== "undefined" && e.ref.PercentLoaded()){
//Set up a timer to periodically check value of PercentLoaded
var loadCheckInterval = setInterval(function (){
//Once value == 100 (fully loaded) we can do whatever we want
if(e.ref.PercentLoaded() === 100){
//Execute function
fn();
//Clear timer
clearInterval(loadCheckInterval);
}
}, 1500);
}
}, 200);
}
//This function is invoked by SWFObject once the <object> has been created
var callback = function (e){
//Only execute if SWFObject embed was successful
if(!e.success || !e.ref){ return false; }
swfLoadEvent(function(){
//Put your code here
alert("The SWF has finished loading!");
});
};
swfobject.embedSWF("movie.swf", "flashcontent", "550", "400", "9", false, false, false, false, callback);

pipwerks答案工作正常。 你甚至可以获得更低的价值:而不是1500,只有100可以。
但我在Firefox上遇到了一些问题。 而不是超时,initialTimeout应该是一个timeInterval,因为在FF有时,在第一次调用时你将e.ref.PercentLoaded未定义,但下一次调用将没有问题。 当然你需要调用clearInterval(initialTimeout); if if是真的。
所以你会得到像:
var initialTimeout = setInterval(function (){
if(typeof e.ref.PercentLoaded !== "undefined" && e.ref.PercentLoaded()){
clearInterval(initialTimeout);
