js如何利用正则和findIndex 来匹配出array中所有符合条件的index？

Question

有以下 array[  {name: '小红', age: 15},  {name: '小明', age: 14},  {name: '小强', age: 13},  {name: '老张', age: 22},  {name: '王小兰', age: 16},  {name: '张小', age: 18},]能否利用正则和findIndex类似的方法，来匹配出所有符合 name中带有 ‘小’的index？比如这次返回的是 [0,1,2,4,5]

Answer 1

let resIndexs = [];

let searchStr = '小';

let data = [

  {name: '小红', age: 15},

  {name: '小明', age: 14},

  {name: '小强', age: 13},

  {name: '老张', age: 22},

  {name: '王小兰', age: 16},

  {name: '张小', age: 18},

];

data.forEach((d, i) => {

  if (d.name.indexOf(searchStr) !== -1) {

    resIndexs.push(i);

  }

});

console.log(resIndexs); // [0, 1, 2, 4, 5]
