要获取el-tree中选中的数据,可以使用以下方法:this.$refs.tree.getCheckedKeys()。这个方法会返回一个数组,包含了选中节点的id。但是需要注意的是,该方法只能获取到选中节点的id,无法获取到父节点的id。如果需要同时获取到选中节点和父节点的id,可以使用下面的方法:
let checkedData = this.$refs.tree.getCheckedKeys().concat(this.$refs.tree.getHalfCheckedKeys())。这样可以获取到所有选中节点和半选中节点的id,其中半选中节点是指部分子节点被选中但父节点未被选中的情况。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
