尝试解决此问题。我有这个＆＃34; Users_Data＆gt; Heard_Sound＆＃34;。我希望它执行一个函数＆＃34; play_sound＆＃34;如果Heard_Sound在任何这个数组中等于no。我希望它只执行一次。不是每个人都有一个＆＃34; Heard_Sound＆＃34;等于不喜欢它现在
{
User_name: "Jon Doe",
Mail_Id: "luiokiikukijuytjrytj",
Role: "Cfo",

photo: "http://www.kktv.com/content/news/Help-authorities-identify-this-John-Doe-in-El-Paso-County-405067576.html",
Heard_Sound: "No"
}
如果我有50个以上代码，它会同时为每个代码播放声音，使其非常响亮

Audio("Assets/Audio/Alert_Sound/Alert_01.mp3");

您可以为此维护一个全局变量。 HEARD_ONCE
相应地更改play_sound功能
let HEARD_ONCE = false;
function play_sound(Heard_Sound){
if(Heard_Sound == 'Noo' && !HEARD_ONCE){
HEARD_ONCE = true;
let Audio_File = new
Audio("Assets/Audio/Alert_Sound/Alert_01.mp3");
setTimeout(function(){
Audio_File.play();
}, 2000);
}
}
