+ <h1>SoundManager 2: Lazy Loading Example</h1>
+ <p>This is an example of dynamically loading SoundManager 2 using JS, after window.onload() has fired.</p>
+ <h2>How it works</h2>
+ <p>This page waits until window.onload(), delays 1 second and loads soundmanager2.js, which should then start up.</p>
+
+<p>SoundManager 2 status: <b id="sm2-status">Waiting for window.onload()...</b></p>
+
+<pre>window.onload = function() {
+ <span>// Window loaded, waiting 1 second...</span>
+ setTimeout(function() {
+ <span>// Loading soundmanager2.js...</span>
+ loadScript('../../script/soundmanager2.js',function() {
+ <span>// SM2 script has loaded</span>
+ soundManager.url = '../../swf/';
+ soundManager.onready(function() {
+ if (soundManager.supported()) {
+ soundManager.createSound({
+ id:'foo',
+ url:'../_mp3/mouseover.mp3'
+ }).play();
+ }
+ <span>// msg(soundManager.supported()?'started OK':'Loaded OK, but unable to start: unsupported/flash blocked, etc.');</span>
+ });
+ soundManager.beginDelayedInit(); <span>// ensure start-up in case document.readyState and/or DOMContentLoaded are unavailable</span>
+ });
+ },1000);
+}</pre>
+
+ <h2 id="flashblock-handling">Handling flash blockers</h2>
+ <p>It's good to let users see the flash component of SM2, so those with flash blockers can unblock it and allow SM2 to start. For more info on this, see the <a href="../flashblock/" title="SoundManager 2 with Flash block handling" onclick="if (!document.domain) this.href=this.href+'index.html'">Flashblock</a> example.</p>
+
+ <h2>Making SM2 wait for window.onload()</h2>
+ <p>If you prefer to have the library wait for window.onload() before calling soundManager.onload()/onerror() methods, you can modify SM2's "waitForWindowLoad" property:</p>
+<code>soundManager.waitForWindowLoad = true;</code>
+ <h2 style="margin-top:1em">Disabling debug output</h2>
+ <p>SoundManager 2 will write to a debug <div> element or a javascript console if available, by default. To disable it, simply set the relevant property to false:</p>
+<code>soundManager.debugMode = false;</code>
+ <p>To see related configuration code, refer to the source of this page which basically does all of the above "for real."</p>
+ <h2>Troubleshooting</h2>
+ <p>If SM2 is failing to start and throwing errors due to flash security, timeouts or other issues, check out the <a href="../../doc/getstarted/#troubleshooting" title="SoundManager 2 troubleshooting tool" onclick="if (!document.domain) this.href=this.href.replace(/\#/,'index.html#')">troubleshooting tool</a> which can help you fix things.</p>
+ <h2>No-debug, compressed version of soundmanager2.js</h2>
+ <p>Once development is finished, you can also use the "minified" (60% smaller) version of SM2, which has debug output and comments removed for you: <a href="../../script/soundmanager2-nodebug-jsmin.js">soundmanager2-nodebug-jsmin.js</a>. If you can, serve this with gzip compression for even greater bandwidth savings!</p>
