我的数据是这样的，this.$refs.tree.setChecked(data,false); this.$refs.tree.getNode(data).checked
都是生效， 怎么回事，用例子给的数据 就生效，是数据有什么问题吗？

elementTree.setChecked方法用于设置元素的选中状态。如果在使用时出现setChecked方法不生效的情况，可能的原因有以下几种：-
元素不存在：在JavaScript中，元素对象的
checked属性是undefined。因此，即使在元素存在的情况下，setChecked方法也无法生效。 -
elementTree对象不存在：在JavaScript中，elementTree对象的实例是一个对象，如果这个对象不存在，那么setChecked方法也无法生效。 -
状态不存在：在JavaScript中，元素的状态可以通过
elementTree.setAttribute方法进行设置。如果elementTree.setAttribute方法也返回undefined，那么setChecked方法也无法生效。 -
问题在于你可能在其他地方调用了
elementTree.setChecked方法，但是你的代码没有正确地调用这个方法。
因此，如果
setChecked方法不生效，你需要检查一下你的代码，确保你正确地调用了elementTree.setChecked方法。 -
