由于很多移動終端不支持 Flash,因此許多絢麗多彩的 Flash效果出不來。如果，能夠判斷出訪問Web網(wǎng)頁的類型(PC還是移動終端)。就可以對癥下藥，找出解決的辦法！

訪問的類型為移動終端我們就用.gif代替Flash(.swf后綴)動畫，PC端就不做改變。這樣就比較完美了！

如下所示,函數(shù) flashChecker() 就是用來檢測訪問的類型。

復(fù)制代碼代碼如下:

 
<script language="javascript" type="text/javascript"> 
/* 
*用來檢測是 PC還是移動終端 
*返回：flashChecker().f == true PC終端 
* 反之為移動終端 
*/ 
function flashChecker() { 
var hasFlash = 0; 
var flashVersion = 0; 
var isIE = /*@cc_on!@*/0; 
if (isIE) { 
var swf = new ActiveXObject("ShockwaveFlash.ShockwaveFlash"); 
if (swf) { 
hasFlash = 1; 
VSwf = swf.GetVariable("$version"); 
flashVersion = parseInt(VSwf.split(" ")[1].split(",")[0]); 
} 
} 
else { 
if (navigator.plugins && navigator.plugins.length > 0) { 
var swf = navigator.plugins["Shockwave Flash"]; 
if (swf) { 
hasFlash = 1; 
var words = swf.description.split(" "); 
for (var i = 0; i < words.length; ++i) { 
if (isNaN(parseInt(words[i]))) { 
continue; 
} 
flashVersion = parseInt(words[i]); 
} 
} 
} 
} 
return { 
f: hasFlash, v: flashVersion 
}; 
} 
</script> 

擴(kuò)充：

復(fù)制代碼代碼如下:

 
<script language="javascript" type="text/javascript"> 
/* 
* 根據(jù)參數(shù) 輸出swf動畫 
* url ：單擊 swf動畫 后的跳轉(zhuǎn)地址 
* swfLink： *.swf 素材地址 
*/ 
function GetSwfHtml(url, swfLink) { 
html = "<a style='position: absolute; top: 0; left: 0; bottom: 0; right: 0; display: block; " + 
"width: 100%; height: expression(this.parentNode.scrollHeight); filter: alpha(opacity=0);" + 
"opacity: 0; background: #FFF;' href='" + url + "' target='_blank'>" + 
"</a>" + 
"<object width='590' height='55' align='middle'>" + 
"<param name='allowScriptAccess' value='never' />" + 
"<param name='quality' value='high' />" + 
"<param name='wmode' value='transparent' />" + 
"<param name='movie' value='" + swfLink+ "' />" + 
"<embed wmode='transparent' src='" + swfLink+ "' quality='high' " + 
"width='590' height='55' align='middle' allowscriptaccess='never' type='application/x-shockwave-flash' " +

return html; 
}
