使用简单的for循环:

var result = null;
for (var i = 0; i < array.length; i++) { 
  if (array[i].name === "string 1") { 
    result = array[i];
    break;
  } 
}

如果可以，也就是说，如果您的浏览器支持，请使用Array。过滤器，它更简洁:

var result = array.filter(function (obj) {
  return obj.name === "string 1";
})[0];

你可以使用npm中的查询对象。您可以使用筛选器搜索对象数组。

const queryable = require('query-objects');

const users = [
    {
      firstName: 'George',
      lastName: 'Eracleous',
      age: 28
    },
    {
      firstName: 'Erica',
      lastName: 'Archer',
      age: 50
    },
    {
      firstName: 'Leo',
      lastName: 'Andrews',
      age: 20
    }
];

const filters = [
    {
      field: 'age',
      value: 30,
      operator: 'lt'
    },
    {
      field: 'firstName',
      value: 'Erica',
      operator: 'equals'
    }
];

// Filter all users that are less than 30 years old AND their first name is Erica
const res = queryable(users).and(filters);

// Filter all users that are less than 30 years old OR their first name is Erica
const res = queryable(users).or(filters);

使用findWhere方法:

var array = [
    { name:"string 1", value:"this", other: "that" },
    { name:"string 2", value:"this", other: "that" }
];


var result = _.findWhere(array, {name: 'string 1'});

console.log(result.name);

请参见JSFIDDLE

下面是搜索和替换的解决方案

function searchAndUpdate(name,replace){
    var obj = array.filter(function ( obj ) {
        return obj.name === name;
    })[0];
    obj.name = replace;
}

searchAndUpdate("string 2","New String 2");

另一种方法(帮助@NullUserException和@Wexoni的注释)是在数组中检索对象的索引，然后从那里开始:

var index = array.map(function(obj){ return obj.name; }).indexOf('name-I-am-looking-for');
// Then we can access it to do whatever we want
array[index] = {name: 'newName', value: 'that', other: 'rocks'};

您是否在对象列表中查找跨项目的通用搜索(筛选器)而不指定项目键

输入

var productList = [{category: 'Sporting Goods', price: '$49.99', stocked: true, name: 'Football'}, {category: 'Sporting Goods', price: '$9.99', stocked: true, name: 'Baseball'}, {category: 'Sporting Goods', price: '$29.99', stocked: false, name: 'Basketball'}, {category: 'Electronics', price: '$99.99', stocked: true, name: 'iPod Touch'}, {category: 'Electronics', price: '$399.99', stocked: false, name: 'iPhone 5'}, {category: 'Electronics', price: '$199.99', stocked: true, name: 'Nexus 7'}]
function customFilter(objList, text){
if(undefined === text || text === '' ) return objList;
return objList.filter(product => {
    let flag;
    for(let prop in product){
        flag = false;
        flag = product[prop].toString().indexOf(text) > -1;
        if(flag)
        break;
    }
return flag;
});}

执行

customFilter(productList, '$9');
