<h3>Show SWF inline, wait indefinitely for load (click-to-run or whitelist)</h3>
|
||
|
|
|
||
|
|
<p class="note">You can run this demo with <a href="#flash8" onclick="window.location.replace(this.href);window.location.reload()">Flash 8</a> (default), <a href="#flash9" onclick="window.location.replace(this.href);window.location.reload()">Flash 9</a> (normal mode) or <a href="#flash9-highperformance" onclick="window.location.replace(this.href);window.location.reload()">Flash 9 + highPerformance mode</a> (higher JS callback frequency).</p>
|
||
|
|
|
||
|
|
<h4>Where (and when) to show the SWF</h4>
|
||
|
|
|
||
|
|
<p>To handle potential flash block cases, put <code><div id="sm2-container"></div></code> in your markup where you'd like the SWF to appear in those cases. If not specified, SM2 will create and append the <code>#sm2-container</code> node to the document when it starts.</p>
|
||
|
|
|
||
|
|
<p>When <code>soundManager.useFlashBlock</code> is true, SM2 will not apply styles (eg. <code>style.position.left</code>) directly to the flash; rather, it will assign CSS classes and you can handle it as you choose. Take a look at <a href="#flashblock-css">the related CSS</a> file you will also need if you turn this feature on.</p>
|
||
|
|
|
||
|
|
<h4>Handling failed start-up cases</h4>
|
||
|
|
|
||
|
|
<p>In the blocked/failed start-up case, <code>#sm2-container</code> will have a class name of <code>swf_timedout</code> applied to it.</p>
|
||
|
|
|
||
|
|
<p>SM2 will start its init process, and will fire <code>onready()</code>, <code>onload()</code> and <code>onerror()</code> handlers accordingly. Keep in mind that while <code>onerror()</code> may fire at first, it may be preceded by a successful <code>onload()</code> if the user first loads the page and then later unblocks the flash movie.</p>
|
||
|
|
|
||
|
|
<p>Note that flash blockers may not run when viewing offline (via <code>file://</code>) content, so try viewing this demo online. For FlashBlock (under Firefox), you can also go to <code>about:config</code> using your address bar and change the value of <code>flashblock.blockLocal</code> to test while offline.</p>
|
||
|
|
|
||
|
|
<h3>Flash Block Example</h3>
|
||
|
|
|
||
|
|
<p>Here, Flash is appended by SM2 to the <code>#sm2-container</code> DIV and after a failed start attempt (if you have a blocker active), will have a <code>swf_timedout</code> class appended.</p>
|
||
|
|
|
||
|
|
<p>The SWF uses <code>position:absolute</code> and negative left/top values so as not to affect the normal page layout, but shifts to <code>left:auto;top:auto</code> (effectively left/top:0) in the blocked case, and becomes visible to the user. On a successful unblock, the movie goes back to left/top:-9999em and is hidden from view.</p>

<h3 id="flashblock-css">Flash Block-related CSS</h3>
|
||
|
|
|
||
|
|
<p>When <code>soundManager.useFlashBlock</code> is enabled, CSS is applied to <code>#sm2-container</code> depending on the progress of SM2's start-up.</p>
|
||
|
|
<p>This page + demos use the rules below, fully-defined and commented in <a href="flashblock.css">flashblock.css</a>. Use it as a base for your own SM2 + flash block implementations.</p>
