el-tree-select 节点点击

el-tree-select节点点击的问题可能是由于冲突导致的。其中可能存在两种冲突情况。第一种是点击事件冲突，可能是因为触发了两次点击，一个是当前节点的handleNodeClick，另一个是onclick，导致了背景色丢失。解决这个问题可以检查代码中是否存在重复的点击事件，并进行相应的处理。第二种是驱动tree高亮的冲突，可能是因为在需要点击按钮让tree高亮显示时，值可能为null导致样式节点丢失。解决这个问题可以使用条件判断来避免空值导致的问题。例如使用`newVal && this.$refs.tree.setCurrentKey(newVal)`来进行空值判断。\[3\]
