根据 where like 条件按属性过滤对象数组

Question

我需要过滤特定属性与用户类型匹配的对象数组。

鉴于此

peopleList = [ 
  {name: "john bee", age:23},
  {name: "john woo", age:43},
  {name: "jim foo", age:101},
  {name: "bob wow", age:67},
  {name: "last john", age:43},
]

只要用户输入第一个字符，我就想过滤数组，而不是完全匹配，而是“喜欢的地方”。

我已经检查了这个问题： Filtering array of objects with lodash based on property value

但它只返回一个完全匹配或不返回任何内容。

我可以使用什么 lodash 函数来返回一个对象数组，其中 name 属性与用户输入的查询字符串相匹配，这样如果用户键入“Jo”，就会返回：

[ 
  {name: "john bee", age:23},
  {name: "john woo", age:43},
  {name: "last john", age:43},
]

如果这很重要，我正在使用 Angular。

Answer 1

试试这个

const peopleList = [ 
  {name: "john bee", age:23},
  {name: "john woo", age:43},
  {name: "jim foo", age:101},
  {name: "bob wow", age:67},
  {name: "last john", age:43},
]
const search = "jo"

cosnt subList = peopleList.filter((person)=>person.name.indexOf(search) > -1)

Answer 2

在 es6 语法中看起来像

const filteredArray = peopleList.filter( people => people.name.includes(someText) );

Answer 3

这是没有 lodash 和纯 javascript 的工作 sn-p：

var peopleList = [ 
  {name: "john bee", age:23},
  {name: "john woo", age:43},
  {name: "jim foo", age:101},
  {name: "bob wow", age:67},
  {name: "last john", age:43},
];

var result = peopleList.filter(person => person.name.includes("jo"));

console.log(result);
