iOS杂记

验证正式环境的远程推送是否正常

可以用Ad Hoc的分发方式，打包上传蒲公英，然后安装到手机。

前端杂记

作者

微信小程序云开发实现关键词搜索

if (keyword) {
    param.title = db.RegExp({
      regexp: event.keyword,
      options: 'i',
    })
  }

将鼠标光标改成小手形状(意指可点击)

style="cursor: pointer;"

created与mounted的区别

created //通常用于初始化某些属性值，例如data中的数据，然后再渲染成视图。
mounted //通常在初始化页面完成后，对html的dom节点进行需要的操作。

el-input中监听键盘事件“回车”

<el-input @keyup.enter.native="login()" "></el-input>

input监听回车键

<input @keyup.enter="login()" />

全局忽略eslint的报错

在项目根目录创建文件.eslintignore
内容为src，保存即可

JavaScript中的filter()和includes()

作者

数组a=[{"name":"张三","id":1},{"name":"李四","id":2},{"name":"王五","id":3}]，
如何筛选出id为1和id为2的对象？

const a = [{"name":"张三","id":1},{"name":"李四","id":2},{"name":"王五","id":3}];

const filtered = a.filter(obj => [1, 2].includes(obj.id));

console.log(filtered); // [{"name":"张三","id":1},{"name":"李四","id":2}]
