我有一个数组
var arrList = [{
"email": "[email protected]",
"pname": "john doe1" },
{
"email": "[email protected]",
"pname": "john doe2" },
{
"email": "[email protected]",
"pname": "john doe3" } ]
我想转换这个数组，并希望输出如下
{
"[email protected]": [{
"email": "[email protected]",
"pname": ["john doe1", "john doe2", "john doe3"]
}]
}
我在下面尝试了lodash但没有成功
arrList = _.uniqBy(arrList, "email", "pname")
result = _.chain(arrList).groupBy('email').value('')
在数组中，有多个不同的电子邮件呈现，我们需要按电子邮件分组。
使用_.groupBy()，然后_.map()将分组的对象转换为请求的形式：
var arrList = [{"email":"[email protected]","pname":"john doe1"},{"email":"[email protected]","pname":"john doe2"},{"email":"[email protected]","pname":"john doe3"}];
var result = _(arrList)
.groupBy('email')
.map((v, email) => ({
email,
pname: _.map(v, 'pname')
}))
.value();
console.log(result);<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js"></script>本文收集自互联网，转载请注明来源。
