由於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網頁的類型(PC還是移動終端)。就可以對症下藥，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後綴)動畫，PC端就不做改變。這樣就比較完美了！
如下所示,函數flashChecker() 就是用來檢測訪問的類型。
複製代碼代碼如下:
<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>
擴充：
複製代碼代碼如下:
<script language="javascript" type="text/javascript">
/*
* 根據參數輸出swf動畫
* url ：單擊swf動畫後的跳轉地址
* 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;
}
