请教能否在网页中播放警报声
请问能否在网页中播放警报声?
比如我添加了一个变量$AlarmThreshold,当它超过某个阈值时自动播放该声音?这样怎么弄好呢?是不是要添加一个flash之类的呢?求方法。
------解决方案--------------------
php不能说话的。。要用flash或html的媒体标签
------解决方案--------------------
那你总得也要跟前端交互才行啊。
最终还是要js去触发
------解决方案--------------------
这要用js控制,可以用PHP在页面放一个判断值,用js获取其中的value,然后再输出报警声:
- JScript code
<script> <?php if(!empty($alarmList)){ ?> //这里的src指向声音文件 $("#music").html('<embed id = "soundControl1" src = "./style/baojing.mp3" mastersound hidden = "true" loop ="true" autostart = "true">'); <?php }else{ ?> $("#music").html(""); ?> </script> <div id="music"></div> <div class="clear"> </div>
