这是我的意见:
data = [
{ name: "John Cena", groupName: "WWE" },
{ name: "Nandini", groupName: null },
{ name: "Rock", groupName: "WWE" },
{ name: "Vinay", groupName: null },
{ name: "Rey Mesterio", groupName: "WWE" },
{ name: "Gokul", groupName: "FSD" },
{ name: "Rohitha", groupName: "FSD" }
];
我需要以下格式的输出:
requiredFormat = [
{ name: "FSD", value: ["Gokul", "Rohitha"] },
{ name: "WWE", value: ["John Cena", "Rock", "Rey Mesterio"] },
{ name: null, value: ["Nandini", "Vinay"] }
];
您可以使用reduce并检查数组值是否已经存在来完成此操作。 如果是的话，再加上。 如果没有，就创建它。
null
const data = [
{ name: "John Cena", groupName: "WWE" },
{ name: "Nandini", groupName: null },
{ name: "Rock", groupName: "WWE" },
{ name: "Vinay", groupName: null },
{ name: "Rey Mesterio", groupName: "WWE" },
{ name: "Gokul", groupName: "FSD" },
{ name: "Rohitha", groupName: "FSD" }
];
const requiredFormat = data.reduce((acc, el) => {
const found = acc.find(({ name }) => name === el.groupName);
if (found) found.value.push(el.name);
else acc.push({ name: el.groupName, value: [el.name] })
return acc;
}, []);
console.log(requiredFormat);
使用Array.Reduce解决您的问题
const data = [
{ name: "John Cena", groupName: "WWE" },
{ name: "Nandini", groupName: null },
{ name: "Rock", groupName: "WWE" },
{ name: "Vinay", groupName: null },
{ name: "Rey Mesterio", groupName: "WWE" },
{ name: "Gokul", groupName: "FSD" },
{ name: "Rohitha", groupName: "FSD" }
];
const requiredFormat = data.reduce((acc, item, key) => {
const group = acc.find(group => group.name === item.groupName);
if (!group) {
acc.push({name: item.groupName, value: [item.name]})
} else {
group.value.push(item.name);
}
return acc;
}, []);
console.log(requiredFormat);
您可以简单地reduce它并获取object.values()
null
var data = [ { name: "John Cena", groupName: "WWE" }, { name: "Nandini", groupName: null }, { name: "Rock", groupName: "WWE" }, { name: "Vinay", groupName: null }, { name: "Rey Mesterio", groupName: "WWE" }, { name: "Gokul", groupName: "FSD" }, { name: "Rohitha", groupName: "FSD" } ];
var result = Object.values(data.reduce((acc, {name, groupName})=>{
acc[groupName] =acc[groupName] || {name:groupName, value:[]};
acc[groupName].value.push(name);
return acc;
},{}));
console.log(result);
