vue后台系统管理项目：

技术选型：vue + element-ui
菜单权限管理模块功能

角色列表查询，通过（角色名称；角色编号；状态：启用、禁用）进行角色数据搜索。
查询、重置、新建角色功能
角色列表分页实现
角色编辑，角色禁用，角色删除操作
新建角色功能包括对角色名称、菜单权限信息的保存提交

角色权限分配管理功能

element-ui tree组件注意事项
node-key 每个树节点用来作为唯一标识的属性，整棵树应该是唯一的
check-strictly 在显示复选框的情况下，是否严格的遵循父子不互相关联的做法，默认为 false

expand-on-click-node 是否在点击节点的时候展开或者收缩节点，默认值为 true，如果为 false，则只有点箭头图标的时候才会展开或者收缩节点。

check-change 节点选中状态发生变化时的回调，共三个参数，依次为：传递给data属性的数组中该节点所对应的对象、节点本身是否被选中、节点的子树中是否有被选中的节点

props

role.vue模块

1.查询重置搜索

 <!-- 查询重置搜索 -->
    <el-form :model="ruleForm" ref="ruleForm" label-width="100px" class="demo-ruleForm" size="35">
      <el-row>
        <el-col :span="8">
          <div class="grid-content bg-purple-light">
            <el-form-item label="角色名称" prop="roleName">
              <el-input v-model="ruleForm.roleName" placeholder="请输入角色名称"></el-input>
            </el-form-item>
          </div>

        </el-col>
        <el-col :span="24">
          <div class="grid-content bg-purple-light ">
            <el-form-item>
              <el-button type="primary" @click="submitForm('ruleForm')">查询</el-button>
              <el-button @click="resetForm('ruleForm')">重置</el-button>

        </el-col>
      </el-row>
    </el-form>

2.table列表

<!--列表-->
    <el-table :data="tableData" border highlight-current-row v-loading="loading" element-loading-text="拼命加载中"
              style="width: 100%;height:auto;" :header-cell-style="{textAlign: 'center',background:'#fafafa'}"
              :cell-style="{ textAlign: 'center' }">

        </template>
      </el-table-column>
    </el-table>

3.分页

<el-pagination background @size-change="handleSizeChange" @current-change="handleCurrentChange"
                   :current-page="pagination.page" :page-sizes="[10, 20, 30, 40,50]" :page-size="pagination.pageSize"
                   layout="total, sizes, prev, pager, next, jumper" :total="pagination.total"></el-pagination>

4.新建/编辑角色弹窗

 <!-- 新建发送弹框 -->
    <el-dialog title="新建角色" :visible.sync="dialogFormUser">
      <el-form ref="newRoleForm" :rules="rules" :model="newRoleForm" label-width="100px">

5.接口引入

import {
  getRolePage,//获取角色列表
  addRole,//添加角色
  allMenu,//菜单列表
  disableRoleEnable,//禁用角色
  roleEditInfo,//角色编辑
  updateEditRole, //更新角色
  delSysRole//删除角色
} from "../../api/userMG";

6.data定义

data() {
    return {
      loading: false, //是显示加载
      isCanUse: false,
      dialogFormUser: false,
      checkStrictly: true,
      pagination: {
        page: 1,
        pageSize: 10,
        total: 0
      },
      ruleForm: {

          {required: true, message: "请输入角色名称", trigger: "blur"}
        ]
      },
      treeCheckedData: [],
      CheckedData: [], //选择新建角色的勾选
      tableData: [],
      data2: [],
      roleId: "",
      defaultProps: {
        children: "childMenu",
        label: "name"
      }
    };
  },

7.methods方法

查询数据

submitForm(ruleForm) {
      this.$refs[ruleForm].validate(valid => {
        if (valid) {
          this.pagination.page = 1;
          this.getRolePageFun();
        } else {
          console.log("error submit!!");
          return false;
        }
      });
    },

重置数据

resetForm(ruleForm) {
      this.pagination.page = 1;
      this.$refs[ruleForm].resetFields();
      (this.ruleForm.roleName = ""),

        (this.ruleForm.disable = ""),
        (this.ruleForm.pageNum = 1);
      this.ruleForm.pageSize = this.pagination.pageSize;
      this.getRolePageFun();
    },

选择一页几条数据

handleSizeChange(val) {
      this.pagination.pageSize = val;
      this.pagination.page = 1;
      this.getRolePageFun();
    },

      this.dialogFormUser = true;
    },

启用和禁用角色

handleDisableClick(row) {
      console.log(row, "row");

            id: row.id
          };
          disableRoleEnable(params)
            .then(res => {
              this.loading = false;
              if (res.code == 200) {
                console.log("开启或者禁用");
                this.$message.success(
                  row.disable == true ? "启用成功" : "禁用成功"
                );
                this.reload();
              } else {
                this.$message.error(res.msg);
              }
            })
            .catch(err => {
              this.loading = false;
              this.$message.error("菜单加载失败，请稍后再试！");
            });
        })
        .catch(() => {
          this.$message({
            type: "info",
            message: "已取消操作"
          });
        });
    },

删除角色，根据角色id

delFun(row) {
      this.$confirm(
        "是否将此用户删除?",
        "提示",
        {
          confirmButtonText: "确定",
          cancelButtonText: "取消",
          type: "warning"
        }
      ).then(() => {
        delSysRole({id: row.id}).then(res =>{
          if (res.code === 200) {
            this.$message.success("操作成功");
            this.reload();
          }else {
            this.$message.warning(res.msg);
          }
        })
      }).catch(() => {
        this.$message.info("取消操作");
      })
    },

添加角色

addNewRole() {
      this.dialogFormUser = true;
      this.treeCheckedData = [];
      this.newRoleForm.roleName = "";
      this.roleId = "";
      this.getAllMenu();
    },

点击节点选中（节点选中状态发生变化时的回调）

handleChecked(data) {
      this.CheckedData = this.$refs.tree.getCheckedKeys();
    },

立即保存角色

saveRole() {
      this.addRoleFun();
    },

点击编辑

handleEditClick(row) {
      console.log(row, "row");
      this.dialogFormUser = true;
      // /sysRole/info// 根据id查看角色详情
      roleEditInfo(row.id)
        .then(res => {
          this.loading = false;
          if (res.code == 200) {
            console.log(res.data, "根据id查看角色详情");
            this.getAllMenu();
            this.roleId = res.data.id;
            // this.newRoleForm.id = res.data.id;
            this.newRoleForm.roleName = res.data.roleName;
            let that = this;
            setTimeout(function () {
              res.data.menuIds.forEach(value => {
                that.$refs.tree.setChecked(value, true, false);
              });
            }, 1000);
          } else {
            this.$message.error(res.msg);
          }
        })
        .catch(err => {
          this.loading = false;
          this.$message.error("菜单加载失败，请稍后再试！");
        });
    },

新建角色

getRolePageFun() {
      this.ruleForm.pageNum = this.pagination.page;
      this.ruleForm.pageSize = this.pagination.pageSize;
      getRolePage(this.ruleForm)
        .then(res => {
          this.loading = false;
          if (res.code == 200) {
            console.log(res.data, "角色列表函数");
            this.tableData = res.data.records;
            this.pagination.total = res.data.total;
          } else {
            this.$message.error(res.msg);
          }
        })
        .catch(err => {
          this.loading = false;
          this.$message.error("菜单加载失败，请稍后再试！");
        });
    },

添加角色保存函数

addRoleFun(newRoleForm) {
      console.log(this.newRoleForm, "this.newRoleForm");
      if (this.newRoleForm.roleName == "") {
        this.$message.error("角色名称不能为空");
      } else if (this.CheckedData.length == 0) {
        this.$message.error("权限不能为空");
      } else {
        if (this.roleId == "") {
          this.newRoleForm.menuIds = this.CheckedData;
          addRole(this.newRoleForm)
            .then(res => {
              this.loading = false;
              console.log(res, "添加角色");
              if (res.code == 200) {
                this.$message.success("添加成功");
                this.reload();
              } else {
                this.$message.error(res.msg);
              }
            })
            .catch(err => {
              this.loading = false;
              this.$message.error("菜单加载失败，请稍后再试！");
            });
        } else {
          this.newRoleForm.menuIds = this.CheckedData;
          this.newRoleForm.id = this.roleId;
          console.log(this.newRoleForm.menuIds, "id获取");
          updateEditRole(this.newRoleForm)
            .then(res => {
              this.loading = false;
              console.log(res, "编辑角色");
              if (res.code == 200) {
                this.$message.success("编辑成功");
                this.reload();
              } else {

            });
        }
      }
    },

获取所有的菜单函数

getAllMenu() {
      allMenu()
        .then(res => {
          this.loading = false;
          console.log(res.data, "获取所有的菜单");
          if (res.code == 200) {
            this.data2 = res.data;
          } else {
            this.$message.error(res.msg);
          }
        })
        .catch(err => {
