Question

我有一个像这样的对象数组：

result = [{
        email: 'jaiswal.shubham84@gmail.com',
        profile: './image/jaiswal.shubham84@gmail.com/6.jpg'
    },
    {
        email: 'sj1303058@gmail.com',
        profile: './image/sj1303058@gmail.com/5.jpg'
    }
]

如何根据result在email中找到正确的对象？

我认为@Gabriel Bleu很好地回答了这个问题。我只想补充一点：如果你想要所有符合条件的对象，请使用filter代替find：

result = [{
        email: 'jaiswal.shubham84@gmail.com',
        profile: './image/jaiswal.shubham84@gmail.com/6.jpg'
    },
    {
        email: 'sj1303058@gmail.com',
        profile: './image/sj1303058@gmail.com/5.jpg'
    },{
        email: 'jaiswal.shubham84@gmail.com',
        profile: 'heyehye'
    },
    {
        email: 'hahahahaha@gmail.com',
        profile: 'hahahaha'
    }
]

//every matching email. Returns an array of all matching (even if only one)
const filtered = result.filter(r => r.email === 'jaiswal.shubham84@gmail.com')
//only one. Will be the first one found so returns an object
const found = result.find(r => r.email === 'jaiswal.shubham84@gmail.com')

console.log("filtered : " + JSON.stringify(filtered))
console.log("found : " + JSON.stringify(found))

如果以前没有安装lodash那么

var lodash = require（“lodash”）;

function getobject(array,keyvalue)
{

  var obj = lodash.filter(array, { 'email': keyvalue } );

  return picked[0].profile;
}
