从文件中的javascript客户端脚本播放音频时出现问题，autostart = true [英] Problem playing audio from a javascript client side script in a file, autostart = true
问题描述
我正在尝试播放一个音频文件，该音频文件在单击按钮时会发出蜂鸣声.它是一个客户端脚本，音频需要嵌入到项目中.由于某种原因，除非我在对象中设置了autostart = true并嵌入，否则它无法正常工作.但是问题是，如果我将autostart = true放置，则在页面加载时和单击button时会听到蜂鸣声.如果我设置为autostart = false，那么当我单击该按钮时，页面不会发出蜂鸣声.但是我不希望它在加载页面时发出哔哔声.
I am trying to play a audio file which makes a beep when I click a button. Its a client side script and the audio needs to be embedded in the project. For some reason, its not working unless i set autostart=true in the object and embed . But the problem is that if i put autostart=true, i hear beeping when the page loads and when I click on button . If i set autostart=false, then the page doesnt make a beeping sound when i click on the button. But I do not want it to beep when I load the page.
<script language="javascript" type="text/javascript">
var button;
var label1;
function PlayIt(movname) {
var movname = eval("document." + movname);
movname.Play();
}
</script>
