使用dojo对tree进行动态操作

动态添加：

var treeNode = backuptarget_treeStore_position.getValue(controlitem,"value");//controlitem为当前需要添加节点的树节点

//controlitem = item;

if(item.children==undefined)

{

var childnum = 0;

}

else{

var childnum = item.children.length;

}

//alert(childnum);

backuptarget_treeStore_position.newItem({label: builderfilename,

id: treeNode+'.'+(childnum+1),value:mount_confirm+path_clickall,children:[]},{parent:controlitem, attribute:'children'});

删除：

backuptarget_treeStore_position.deleteItem(controlitem);

backuptarget_treeStore_position.save();

对newitem和deleteitem需要灵活运用，才能实现自己项目的使用
