這篇文章主要介紹了Vue使用zTree插件封裝樹(shù)組件操作,結(jié)合實(shí)例形式分析了vue.js整合zTree插件實(shí)現(xiàn)樹(shù)組件與使用相關(guān)操作技巧,需要的朋友可以參考下

本文實(shí)例講述了Vue使用zTree插件封裝樹(shù)組件操作。分享給大家供大家參考，具體如下：

1.通過(guò)npm安裝jquery

npm install jquery --save-dev

2.在build/webpack.base.conf文件當(dāng)中引入jquery

module.exports = {
  ...
  resolve: {
    extensions: ['.js', '.vue', '.json'],
    alias: {
      'vue$': 'vue/dist/vue.esm.js',
      '@': resolve('src'),
      'jquery': path.resolve(__dirname, '../node_modules/jquery/src/jquery')
    }
  },
  ...
}

3.在項(xiàng)目根目錄創(chuàng)建一個(gè)文件夾plugins，將zTree的js文件放進(jìn)去

4.將zTree的樣式文件放在static文件夾下（放在別的地方大飽之后會(huì)出現(xiàn)圖片路徑找不到等問(wèn)題，放在static下打包時(shí)會(huì)避免ztree樣式的壓縮）。在main.js中引入該樣式：

import '../static/zTreeStyle/zTreeStyle.css'

5.創(chuàng)建公共組件ztree>index.vue，下面為我的公共組件

html：

<template>
  <div class="ztree">
    <el-row>
      <el-col :span="12">
        <el-button icon="el-icon-plus" size="mini" type="text" @click="add">新增節(jié)點(diǎn)</el-button>
      </el-col>
      <el-col :span="12">
        <el-button icon="el-icon-delete" type="text" size="mini" @click="remove">刪除節(jié)點(diǎn)</el-button>
      </el-col>
    </el-row>
    <ul id="treeDemo" class="ztree"></ul>
    </div>
</template>

js：

<script>
import '../../../plugins/zTree/jquery-1.4.4.min'
import '../../../plugins/zTree/jquery.ztree.core'
import '../../../plugins/zTree/jquery.ztree.excheck'
import '../../../plugins/zTree/jquery.ztree.exedit'
export default {
  props: {
    zNodes: {
      type: Array
    },
    selectedNodeId: ""
  },
  data() {
    return {
      selectedNode: {},
      setting: {
        view: {
          showIcon: false
        },
        edit: {
          enable: true,
          showRemoveBtn: false,
          showRenameBtn: false
        },
        data: {
          keep: {
            parent: true,
            leaf: true
          },
          simpleData: {
            enable: true
          }
        },
        callback: {
          onClick: this.zTreeOnClick,
          onRename: this.zTreeOnRename
        }
      }
    };
  },
  methods: {
    // 初始化ztree
    init() {
      $.fn.zTree.init($("#treeDemo"), this.setting, this.zNodes);
    },
    // 樹(shù)節(jié)點(diǎn)點(diǎn)擊事件
    zTreeOnClick: function(event, treeId, treeNode) {
      this.selectedNode = treeNode;
      this.$emit("treeClick", treeNode);
    },
    // 樹(shù)節(jié)點(diǎn)編輯名稱(chēng)回調(diào)
    zTreeOnRename(event, treeId, treeNode, isCancel) {
      this.$emit("addNode", treeNode);
    },
    // 點(diǎn)擊添加按鈕事件
    add() {
      let newCount = 1;
      let zTree = $.fn.zTree.getZTreeObj("treeDemo"),
      nodes = zTree.getSelectedNodes(),
      treeNode = nodes[0];
      if (treeNode) {
        if (treeNode.level === 2) {
          this.$message("分類(lèi)不能超過(guò)三級(jí)");
          return;
        } else {
          treeNode = zTree.addNodes(treeNode, {
            id: 100 + newCount,
            isParent: true,
            pId: treeNode.id,
            name: "new node" + newCount++
          });
        }
      } else {
        treeNode = zTree.addNodes(null, {
          id: 100 + newCount,
          isParent: true,
          pId: 0,
          name: "new node" + newCount++
        });
       }
      zTree.editName(treeNode[0]);
    },
    // 點(diǎn)擊刪除按鈕事件
    remove() {
      let zTree = $.fn.zTree.getZTreeObj("treeDemo"),
      nodes = zTree.getSelectedNodes(),
      treeNode = nodes[0];
      if (nodes.length == 0) {
        this.$message("請(qǐng)先選擇一個(gè)節(jié)點(diǎn)");
        return;
      } else {
        this.$confirm("此操作將永久刪除該節(jié)點(diǎn), 是否繼續(xù)?", "提示", {
          confirmButtonText: "確定",
          cancelButtonText: "取消",
          type: "warning"
        })
        .then(() => {
          this.$emit("removeNode", treeNode);
        })
        .catch(() => {});
      }
    }
  },
  watch: {
    // 監(jiān)聽(tīng)樹(shù)節(jié)點(diǎn)的變化更新樹(shù)
    zNodes: function(val) {
      this.init();
    },
  },
  mounted() {
    this.init();
  }
};
</script>

希望本文所述對(duì)大家vue.js程序設(shè)計(jì)有所幫助。
