你是一次全选么?贴一个最小化复现代码

from vue-easy-tree.

我是模拟了获取数据,默认选中的

<template>
  <div>
    <el-button type="primary" @click="setTreeValue">赋值</el-button>
    <vue-easy-tree
      ref="veTree"
      node-key="id"
      height="400px"
      :data="treeData"
      :props="props"
      :show-checkbox="true"
      :default-expanded-keys="['abc']"
      :default-checked-keys="checkSelectKeys"
    ></vue-easy-tree>
  </div>
</template>

<script>
import VueEasyTree from "@wchbrad/vue-easy-tree";
import "@wchbrad/vue-easy-tree/src/assets/index.scss";
export default {
  name: "Test",
  props: [],
  data() {
    return {
      props: {
        label: "name",
        children: "children",
      },
      checkSelectKeys: [],
      treeData: [],
    };
  },
  components: { VueEasyTree },
  created() {},
  mounted() {
    this.setTree();
  },
  methods: {
    setTree() {
      let arr = [];
      for (let i = 0; i < 20000; i++) {
        arr.push({ id: `id-${i}`, name: `name-${i}` });
      }
      let tree = [{ id: "abc", name: "全部", children: arr }];
      this.treeData = tree;
    },
    setTreeValue() {
      let arr = [];
      for (let i = 10; i < 3000; i++) {
        arr.push(`id-${i}`);
      }
      this.checkSelectKeys = arr;
      // this.$refs.veTree.setCheckedKeys(arr);
    },
  },
};
</script>

<style lang="scss" scoped>
</style>

用以下代码替换setTreeValue方法

setTreeValue() {
      let arr = [];
      for (let i = 10; i < 3000; i++) {
        arr.push(`id-${i}`);
      }
      const allNodes = this.$refs["veTree"].store._getAllNodes();

      for (const node of allNodes) {
        if (arr.includes(node.key)) {
          node.checked = true;
        }
      }
},

from vue-easy-tree.

这个方法可以

from vue-easy-tree.

这个还有点小问题,父级没有半选的状态。

from vue-easy-tree.
