在SWFObject上加载计时器以获取SWF加载时间 [英] Load timer on SWFObject for SWF load time

问题描述

有很多人抱怨SWF上的加载时间很慢，但是这个结果看起来很好。

Having a number of people complaining of slow load times on an SWF, but it appears fine this end.

我想添加一个加载计时器SWFObject javascript用于计算加载SWF然后将其发送回给我们需要多长时间（我将通过AJAX执行此操作）。

I'd like to add a load timer in the SWFObject javascript to time how long it takes to load an SWF and then send it back to us (I'll do that via AJAX).

我调查了可能性使用SWFObject回调，每10个小时启动一个计时器，然后一旦成功就会停止。但是，看看这个，如果嵌入成功，而不是加载，这只是一个开关。

I've looked into possibles with SWFObject callback, which starts a timer every 10millisecodns and then will stop once success. But, looking at this, this is just a switch if embed has been successful, not load.

    function loadSWF(playURL){
      swfobject.embedSWF(playURL, "playdiv", "170", "90", "9.0.0", "expressInstall.swf", color:face00}, {wmode:"opaque",allowfullscreen:"true",allowScriptAccess:"always"}, '', function(e) { 

        var loadTimer = window.setInterval(function() {

            if(e.success) {

                milSeconds = milSeconds+10;
                clearInterval(loadTimer); alert('TIME ' + milSeconds);
            } else {

                milSeconds = milSeconds+10;

            }
        },10);          


    });
    }

这就是我现在所拥有的。 Obv不会做我们需要的。

That's what I have right now. Obv won't do what we need.

Has anyone another path to follow?

推荐答案

您还可以查询SWF的 PercentLoaded 属性，而无需向SWF本身添加任何代码。这是一种快速（但草率）的方法：

You can also query the SWF's PercentLoaded property without needing to add any code to the SWF itself. Here's a quick (but sloppy) way to do it:

var start_time, end_time, total_time;

function getCurrentTime(){ return new Date(); }

function checkSWFStatus(swf){
    if(swf.PercentLoaded() !== 100){
        setTimeout(function (){
            checkSWFStatus(swf);
        }, 50);
    } else {
        end_time = getCurrentTime();
        total_time = end_time-start_time;
        console.log("Ended: " +end_time);
        console.log("Total load time: approximately " +total_time +" milliseconds");
    }
}

var callback = function (e){

    if(e.success && e.ref){

        if(!start_time){
            start_time = getCurrentTime();
            console.log("Started: " +start_time);
        }

        //Ensure SWF is ready to be polled
        setTimeout(function checkSWFExistence(){
            if(typeof e.ref.PercentLoaded !== "undefined"){
                checkSWFStatus(e.ref);
            } else {
                checkSWFExistence();
            }
        }, 10);

    }

};

swfobject.embedSWF("yourmovie.swf", "targetelement", "550", "400", "9", false, false, false, false, callback);
