我的问题是，如何才能通过单词找到所有数组索引?

My question is, how can I find all array indexes by a word ?

[
{name: "Jeff Crawford", tel: "57285"},

If I search for "Jeff", I want to get:

[
{name: "Jeff Crawford", tel: "57285"},

推荐答案

要使其更具通用性，您可以采用一个函数，该函数采用对象数组，所需的键和搜索字符串，稍后将其用作小写字母字符串.

To make it more versatile, you could take a function which takes an array of objects, the wanted key and the search string, wich is later used as lower case string.

function find(array, key, value) {
    value = value.toLowerCase();
    return array.filter(o => o[key].toLowerCase().includes(value));
}

var array = [{ name: "Jeff Crawford", tel: "57285" }, { name: "Jeff Maier", tel: "52141" }, { name: "Tim Maier", tel: "73246" }]

console.log(find(array, 'name', 'Jeff'));
