系统信息:

  • 发行平台: [微信小程序]
  • 操作系统 [mac]
  • HBuilderX版本 [1.9.4]
  • 设备信息 [小程序开发工具]
    如图，第一个@click调用本vue页面的methods，可行
    第二个@click调用全局方法，不可行，看报错是去拿了本vue页面的data属性，但实际上应该优先拿v-for里的变量

建议将$store.commit 封装到一个方法里执行，类似第一种用法
$store.commit 的写法属于复杂表达式，使用这种复杂写法，编译至微信时，编译器和运行时均要做很多额外工作，尤其是在 v-for 中，可能会导致性能问题。
