点击保存按钮时，如果form里面的表单验证通过这进入下面代码中的 if(valid) 里面，否者进入else.

  //点击保存按钮
    save () {
        this.$refs['form'].validate((valid) => {
          if (valid) {
              console.log('验证通过') ;
              this.resetFrom();
            });
          } else {
            console.log('验证不通过') ;
            return false;
          }
        });
      },    

PS：表单输入长度控制验证

name: [
  {required: true, message: '请输入活动名称', trigger: 'blur'},
  {min: 3, max: 5, message: '长度在 3 到 5 个字符', trigger: 'blur'}
],
