<script language="javascript" type="text/javascript">
var loaded = false;
$(function(){
if(!loaded){
//加载树
mytree = new dTree(‘mytree‘);
alert("==加载树"+mytree);
<logic:notEmpty name="TREE">
<logic:iterate id="fun" indexId="index" name="TREE">
mytree.add(<bean:write name="fun" property="funSortId"/>,<bean:write name="fun" property="funSortFid"/>,‘<bean:write name="fun" property="funSortName"/>‘,‘‘,<bean:write name="fun" property="flag"/>,<bean:write name="fun" property="check"/>);
</logic:iterate>
</logic:notEmpty>
alert(mytree);
$("#purviewDiv").append(mytree.toString());
loaded = true;
}
});
</script>
这里给了一个开关判断，这样就解决两次加载的事件。
