试图通过JavaScript播放声音,并希望使用的sessionStorage如何动态创建一个JavaScript的sessionStorage内的阵列/ HTML5
下面是一个简化版本,在Android设备/ FF的Linux播放声音/秒动态地改变它/ Win当你点击“sprite me”按钮时 - 我已经包含了其他按钮来设置和检索HTML5中的会话值。

维基下方有Android手机的规格,其中它的工作原理:(三星Galaxy SII)的情况下,你有兴趣
http://globability.org/wiki/doku.php?id=current_working_specs_p-tab /又见http://globability.org/wiki/doku.php?id=mobile_pointing_tablet,以获取有关它是什么,一个正确的想法我正在努力。
我需要的是“play soundsprite”javascript,您可以在下面的部分中从sessionstorage加载并从插入到数组中插入从sessionstorage加载的值。
我不在寻找任何改变是如何播放声音 - 只需要在特定的javascript内部动态构建数组。
下面的代码基于www.phpied.com/audio-sprites/上的Stoyan Stefanov的声音想法 - 用于减少播放声音所需的http调用...还可以稳定声音质量,减少颤音等
Antway这里有云:你只需要看看伪科 - 其余功能
<script>
var thing = 'the thing';
function shut() {
if (typeof thing.pause !== 'undefined') {
thing.pause();
}
}
function log(what) {
document.getElementById('log').innerHTML += what + "<br>";
}
var spriteme = function(){
var sprites = {
// id: [start, length]
'blank':[0.1, 0.5], //This the first sprite, it has to be the first defined and is
called first, it is a blank piece of sound in the combined sound file and needed as of
now.
'success':[13, 2,5],
/* I would like to be able to set the parameters i.e. sound bite to play dynamically -
here a pseudocode example using session storage in preparation for getting the sound
parameters from a database
'wordgen'[null,null];
//this array should be dynamically built from values read from the two session storage keys not sure you need the new thing in HTML5
sessionStorage.globabilitykey1;
sessionStorage.globabilitykey2;
strkey1=globabilitykey1
strkey2=globabilitykey2
var gkey1=parsefloat(strkey1)
var gkey2=parsefloat(strkey2)
'wordgen':[gkey1,gkey2]
and then the idea is to replace the array success in the script with the "generated"
array 'wordgen' to allow dynamic seting of sound to play back */
//the following are sound bites from the collection of soundsprites the site plays from
'word1': [0.5, 2,36], //one
'word2': [3.1, 3.0], //two
'word3': [7.0, 1.82], //three
'word4': [10.03, 2], //four ?
},
song = ['blank', 'success'],
//here you're setting the playback sequence (this is where I would like to replace 'success' with 'wordgen'
current = 0,
id = song[current],
start = 0,
end = sprites[id][1],
int;
thing = document.getElementById('sprite');
thing.play();
log('file: ' + thing.currentSrc);
log(id + ': start: ' + sprites[id].join(', length: '));
// change
int = setInterval(function() {
if (thing.currentTime > end) {
thing.pause();
if (current === song.length - 1) {
clearInterval(int);
return;
}
current++;
id = song[current];
start = sprites[id][0];
end = start + sprites[id][1]
thing.currentTime = start;
thing.play();
log(id + ': start: ' + sprites[id].join(', length: '));
}
}, 10);
};
</script>
如何动态地根据该值是在JavaScript中创建“wordgen”点阵任何想法sessionstorage?

我知道的页面是一个丑陋的烂摊子......但是这是一个alpha原型:)
***如果您觉得它有帮助,请将问题投票!*** –
http://globability.org/webapp/asprite20111205_5。html - 一个更好的例子,其中setanyvalue(arg1,arg2)函数将任意值传递给sessionstorage,并自动开始播放声音sprite(用于未来版本,使用从数据库读取的值等) –
