Javascript custom function determines whether the website access type is PC or mobile terminal

Since many mobile terminals do not support Flash, many colorful Flash effects cannot be produced. If, the type of accessed Web page (PC or mobile terminal) can be determined. You can prescribe the right medicine and find a solution!

If the type of access is a mobile terminal, we will use .gif instead of Flash (.swf suffix) animation, and there will be no changes on the PC side. This is more perfect!

As shown below, the function flashChecker() is used to detect the type of access.

<script language="javascript" type="text/javascript"> 
/* 
*用来检测是 PC还是移动终端 
*返回：flashChecker().f == true PC终端 
* 反之为移动终端 
*/ 
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>

Expansion:

<script language="javascript" type="text/javascript"> 
/* 
* 根据参数 输出swf动画 
* url ：单击 swf动画 后的跳转地址 
* swfLink： *.swf 素材地址 
*/ 
function GetSwfHtml(url, swfLink) { 
html = "<a style=&#39;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;&#39; href=&#39;" + url + "&#39; target=&#39;_blank&#39;>" + 
"</a>" + 
"<object width=&#39;590&#39; height=&#39;55&#39; align=&#39;middle&#39;>" + 
"<param name=&#39;allowScriptAccess&#39; value=&#39;never&#39; />" + 
"<param name=&#39;quality&#39; value=&#39;high&#39; />" + 
"<param name=&#39;wmode&#39; value=&#39;transparent&#39; />" + 
"<param name=&#39;movie&#39; value=&#39;" + swfLink+ "&#39; />" + 
"<embed wmode=&#39;transparent&#39; src=&#39;" + swfLink+ "&#39; quality=&#39;high&#39; " + 
"width=&#39;590&#39; height=&#39;55&#39; align=&#39;middle&#39; allowscriptaccess=&#39;never&#39; type=&#39;application/x-shockwave-flash&#39; " + 
"pluginspage=&#39;" + url + "&#39; />" + 
"</object>"; 


return html; 
}
