点击添加打开模态框

    // 添加角色
    addRoles() {
      this.ruleForm={
        roleName:"",

      };
      this.dialog = {

        option: "edit",
      };
      this.ruleForm={

        roleDesc:value.roleDesc,
        id:value.id
      }
    },

点击确认按钮判断是添加还是编辑

    onSubmit() {
      this.$refs.cateForm.validate(async (valid) => {
        if (valid) {
          if (this.dialog.option == "edit") {
            const { data: res } = await qqq(this.addCateForm);//qqq请求接口名
            if (res.meta.status !== 200) {
              return this.$message.error("编辑失败！");
            }
            this.$message.success("编辑成功！");
          } else if (this.dialog.option == "add") {
            const { data: res } = await qqq(this.addCateForm);//qqq请求接口名
            if (res.meta.status !== 201) {
              return this.$message.error("添加失败！");
            }
            this.$message.success("添加成功！");
          }
          this.dialog.show = false;
        } else {
          console.log("error submit!!");
          return false;
        }
      });
    },
