expandNode展开节点，checkNode选中其下的某个子节，由于数据太多，初始化的时候，选中的节点在界面上看不到，有没有API可以移动到当前选中的这个子节点，使用户可以看到，而不用再用鼠标拖动滚动条？

selectNode 方法即可

试过了在chrome 18中没有滚动
在IE8中没有滚动到地方，差一个节点就到选中的节点的父节点了。
FF12，只滚动到父节点。

那要看你的 selectNode 方法中的 treeNode 是哪个节点了

请你看看官网提供的 Demo 是否都正常？

忘了说了，我是用js来选中节点。demo中没有我说那种情况：
树有2层，每层下一个节点，树根共计有100节点，如果我js选中第100个节点的子节点，界面是不会滚动到那个节点的，使那个节点可以让用户看到。我的意思是有没有什么API让界面滚动到那个节点是用户可以直接看到。

selectNode 方法就是让 节点自动滚动到可视区域内的呀！

我明白了，你是一边使用 expandNode ，一边使用selectNode 吧

这样有问题，因为 expandNode 是动画效果展开，这个是异步的，所以当selectNode 定位时，还没有完全展开。
建议你使用 expandNode 触发 onExpand 事件，在onExpand 事件中使用 selectNode 方法，这样就没问题了

我要承认这的确是一个 zTree 的bug，但是在 v3.2 中已经得到了修正。 所以请你升级到 v3.2 吧。

OK，我试下，不知道和3.0兼容怎么样，如果没问题，我就升了。。。

childs换成children，别的还没发现兼容不兼容。。。

css 和 img 需要升级的！！！

谢谢，这2个也升级了！

我也遇到这个问题，用expandNode方法展开某个节点（异步），然后用selectNode选中展开后的下级的某个节点，可以选中，但是无法滚动到可视区域，我用的最新版的3.5.35也不行，吧主帮忙回复一下呗
