裡面的SelectionStart SelectionEnd是如何用的，可否控制wmv從一個指定的幀開始，到一個指定的幀結束。
請高手作答，謝謝

<param name=CurrentPosition value=200>
這裡設置為視頻開始播放的時間
頁面onload=SetPause()
function SetPause(){
setTimeout(pause(),1000);
}
function pause(){
var current_time = document.getElementById(mediaplayer1).controls.currentPosition;
if (current_time>parseInt('1261.230')){
toPlay();
}else{
setTimeout(pause(),1000);
}
}
