将具有多个属性的对象数组分组并根据特定值提取值
[英]group an array of object with multiple properties and extract values based on the particular values
问题描述
i wanted to group by an array of object with multiple field and i have done it and i wanted to concat the email first with respect to the reportName and then with respect to the particular events i have done that part but when i am doing that in the fields i get it undefined with them i want to remove that undefined and print only the strings of email.
我想按具有多个字段的对象数组进行分组，我已经完成了，我想首先根据 reportName 连接电子邮件，然后根据特定事件连接我已经完成的那部分，但是当我这样做时我用它们未定义的字段我想删除未定义的字段并仅打印电子邮件字符串。

i have tried to solve this problem using this way我试图用这种方式解决这个问题
const processArray = data.filter(itms => {
return itms.event == 'processed';
});
const openEvent = data.filter(itms => {
return itms.event == 'open';
});
const recieved = data.filter(itms => {
return itms.event == 'delivered';
});
//console.log(processArray)
const processEmailRecord = processArray.map(arrayofObj => ({
processEmail: arrayofObj.email,
office: arrayofObj.office,
reportName: arrayofObj.reportName,
}));
const openEmailRecord = openEvent.map(arrayofObj => ({
openEmail: arrayofObj.email,
office: arrayofObj.office,
reportName: arrayofObj.reportName,
}));
const recEmailRecord = recieved.map(arrayofObj => ({
recEmail: arrayofObj.email,
office: arrayofObj.office,
reportName: arrayofObj.reportName,
}));
const eventwiseArray = [...processEmailRecord, ...recEmailRecord, ...openEmailRecord];
let hash1 = Object.create(null);
let eventArray = [];
eventwiseArray.forEach(o => {
var key = ['office', 'reportName']
.map(function(k) {
return o[k];
})
.join('|');
if (!hash1[key]) {
hash1[key] = {office: o.office, reportName: o.reportName,email:' ',processEmail:'',recEmail:'',openEmail:''};
eventArray.push(hash1[key]);
}
['email'].forEach(k => {
if (hash1[key] && !hash1[key][k].includes(o[k])) {
hash1[key][k] += o[k] + ',';
}
});
['processEmail'].forEach(k => {
if (hash1[key] && !hash1[key][k].includes(o[k])) {
hash1[key][k] += o[k] + ',';
}
});
['recEmail'].forEach(k => {
if (hash1[key] && !hash1[key][k].includes(o[k])) {
hash1[key][k] += o[k] + ',';
}
});
['openEmail'].forEach(k => {
if (hash1[key] && !hash1[key][k].includes(o[k])) {
hash1[key][k] += o[k] + ',';
}
});
});
i am getting output in this way我以这种方式获得输出

but i wanted to get the output without undefined written in front of it.all the emails in it must be unique like my solution's output.但我想得到没有未定义写在它前面的输出。其中的所有电子邮件必须像我的解决方案的输出一样是唯一的。

You could group the mails and add the values to the distinct groups by taking a Set for getting unique emails.您可以将邮件分组并将值添加到不同的组中，方法是使用Set来获取唯一的电子邮件。

I think you've made this more complicated then it has to be, my approach will be something like this:我认为你已经使这变得更复杂了，我的方法将是这样的：

[...v.recEmail].join(), openEmail: [...v.openEmail].join() })); console.log(result);
What this does is to first check (the a.find(..) call) if there was already an object created for the office and reportName of the object at the current iteration ( c ).它的作用是首先检查（ a.find(..)调用）是否已经为当前迭代 ( c ) 的office和对象的reportName创建了一个对象。 If it wasn't, one is created and added to the result array and then, the switch statement adds the email to the appropriate property of the found/created object.如果不是，则创建一个并将其添加到结果数组中，然后switch语句将电子邮件添加到找到/创建的对象的适当属性中。
This approach is not that efficient because of the .find call at each iteration, it can be improved by using a Map or object which has as keys c.office + c.reportName .由于每次迭代.find调用.find ，这种方法效率不高，可以通过使用Map或具有c.office + c.reportName键的object来改进。
