實現(xiàn)功能:
1.由外部參數(shù)flashvars指定數(shù)據(jù)源的文件位置或render鏈接.
2.在源數(shù)據(jù)上加href和target屬性來控制打開窗口.
3.可自定義父節(jié)點和子節(jié)點圖標,不設置采用系統(tǒng)默認.
直接上源碼:

調(diào)用的時候在flashvars里面加上url=xxx
復制代碼 代碼如下:
object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
id="tree" width="242" height="442"
codebase="http://fpdownload.macromedia.com/get/flashplayer/current/swflash.cab">
param name="movie" value="${ctx}/js/as/menu.swf" />
param name="quality" value="high" />
param name="bgcolor" value="#869ca7" />
param name="allowScriptAccess" value="sameDomain" />
!-- 指定菜單的數(shù)據(jù)源 -->
param name="flashvars" value="url=${ctx}/user/user!renderMenu.do?id=${user.usid}" />
embed src="tree.swf" quality="high" bgcolor="#869ca7"
width="242" height="442" name="tree" align="middle"

loop="false"
quality="high"
allowScriptAccess="sameDomain"
type="application/x-shockwave-flash"
pluginspage="http://www.adobe.com/go/getflashplayer">

其中url可以指定xml文件的位置或者render的鏈接
