我正在制作一个小型小行星避免游戏，当我的生命结束时，我正在执行以下代码：
gameover.play();
虽然gameover定义如下：
var gameover = new Audio('gameover.wav');
当我执行代码时，它会循环播放声音，我只想播放一次，我该怎么做？感谢。

我相信将loop属性设置为var products = new kendo.data.Model.define({
id: "ID",
fields: {
ID: { editable: false, type: "number" },
ProductID: { type: "number", nullable: false, editable: true },
Quantity: { type: "number", nullable: false, editable: true },
Description: { type: "string" },
UnitPrice: { type: "number" },
TotalPrice: { type: "number" },
WorkText: { type: "string" },
CreatedDateTime: { type: "date" }
}
});
var dataSource = new kendo.data.DataSource({
transport: {
read: {
url: "/Service/ProductsReadTicket",
dataType: "json"
},
update: {
url: "/Service/ProductsUpdateTicket",
dataType: "json",
contentType: "application/json"
},
create: {
url: "/Service/ProductsCreateTicket",
dataType: "json",
contentType: 'application/json; charset=utf-8'
},
parameterMap: function (options, operation) {
if (operation !== "read" && options.models) {
return { model: options.models };
}
if (operation == "read") {
return { ticketid: iidee };
}
}
},
batch: true,
pageSize: 20,
schema: {
model: products,
data:
function (data) {
return data.Data;
}
}
});
$("#grid3").kendoGrid({
toolbar: ["create", "save", "cancel"],
dataSource: dataSource,
sortable: true,
autobind: false,
pageable: true,
selectable: true,
filterable: true,
columns: [
{ field: "ID", title: "ID", hidden: true },
{ field: "CreatedDateTime", title: "Pvm", format: "{0:dd.MM.yyyy HH:mm}" },
{ field: "ProductID", title: "Tuotenro" },
{ field: "Description", title: "Nimi" },
{ field: "WorkText", title: "Teksti" },
{ field: "Quantity", title: "Määrä" },
{ field: "UnitPrice", title: "Hinta" },
{ field: "TotalPrice", title: "Kokonaishinta" },
],
editable: true
});
即可实现目标。
false
var birdSound = new Audio('http://www.noiseaddicts.com/samples_1w72b820/4929.mp3');
birdSound.loop = false;
birdSound.play();
var birdSound = new Audio('http://www.noiseaddicts.com/samples_1w72b820/4929.mp3');
birdSound.loop = false;
birdSound.play();
var statusElem = document.getElementById('status');
var startTime = Date.now();
updateStatus();
function updateStatus(){
if (birdSound.ended){
statusElem.innerText = 'Stopped';
} else {
statusElem.innerText = 'Playing (' + ( ( Date.now() - startTime ) / 1000 ) + ')';
window.setTimeout(updateStatus, 50);
}
}
