HTML頁面中播放(fàng)Flash視(shì)✔©頻(pín)的(de)時(shí)候，遇到(dào)了(le)一(∑λyī)個(gè)小(xiǎo)問(wèn)題，那(n' à)就(jiù)是(shì)如(rú)果Flash播放(fàng)器(×®σ✘qì)的(de)寬和(hé)高(gāo)不(bù≠§≤‍)合适，那(nà)麽Chrome就(jiù)會(₽ε♦huì)攔截播放(fàng)器(qì)的(de)自(zì)動播放(fàng£♥)

然後必須要(yào)點擊一(yī)下(xià)λπ♥♠播放(fàng)按鈕，才能(néng)繼續播放(fàng)。π♣

給出了(le)下(xià)面幾個(gè)解決方法✘₹≤♦：

1、使用(yòng)ExternalInterface

2、初始化(huà)播放(fàng)器(qì)尺寸大(dà)于398x29↓≤↓∏8，然後使用(yòng)transform: scale()。

Google 到(dào)了(le) Chrλλ±♣ome 官方論談的(de)一(yī)篇帖子(zǐ)。帖子(zǐ)把 ↕δChromium 的(de)源碼都(dōu)給扒出來(lá<☆‌i)了(le)，最終給出了(le)一(yī)個€∑'(gè)解決辦法：

1、跨站(zhàn)（Cross-origin）的(de) fla​&sh 的(de)寬度至少(shǎo)是(shì) 39±®₽8，高(gāo)度至少(shǎo)是(shì) 298，否則會( ♠Ωhuì)被認為(wèi)是(shì)不(bù)重要 ₹♦≠(yào)的(de) flash
2、flash 內(nèi)容的(de)寬度比"↓≈為(wèi) 16:9 的(de) flash 會(huì)被當作↔••(zuò)重要(yào)的(de)，因此可¥×↓(kě)以自(zì)動播放(fàng)。


相(xiàng)關的(de)源碼如(rú)下(xià)：
