由于很多移动终端不支持 Flash,因此 许多绚丽多彩的 Flash效果出不来。如果，能够判断出访问Web网页的类型(PC还是移动终端)。就可以对症下药，找出解决的办法！
访问的类型为移动终端我们就用.gif代替Flash(.swf后缀)动画，PC端就不做改变。这样就比较完美了！
如下所示,函数 flashChecker() 就是用来检测访问的类型。
复制代码代码如下:
<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>
扩充：
复制代码代码如下:
<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='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' " +
"pluginspage='" + url + "' />" +
"</object>";
return html;
}
