javascript obj if condition-CodePudding

I am having trouble on if condition in object array, what I want is add a total count if the id is equal to authorsid

I have this code

let arrAuthorPublished = { name: [], totalCount: [] }
for(let x = 0; x < counts; x  ){
  if(ids == authorsid){
    arrAuthorPublished.name.push(authorName);
    arrAuthorPublished.totalCount.push(total = total   1);
  } else {
    console.log("fail")
  }
}

the value of ids are

[440944522, 440936792, 440936202, 440930072]

and the value of authors are:

[440944522, 440936792, 440936202, 440930072]

UPDATE

const author = async()=>{
    return new Promise((resolve, reject)=>{
        var getAuthor = (`SELECT id, name FROM Author`, 1000, data=>{
            let obj = { ids: [], authorName: [] }
            for(let x = 0; x < data.length; x  ){
                obj.ids.push(data[x][0]);
                obj.authorName.push(data[x][0]);
            }
            return resolve(obj);
        })
    })
}
const transaction = async()=>{
    return new Promise((resolve, reject)=>{
          var getAuthorTransac = (`SELECT  rAuthors, exp_fAuthor FROM Transaction`, 1000, data=>{
              let arrAuthorPublished = { authors: [], counts: [] }
              for(let x = 0; x < data.length; x  ){
                    arrAuthorPublished.authors.push(data[x][0]);
                    arrAuthorPublished.counts.push(data[x][1]);
              }
              return resolve(arrAuthorPublished);
          })
      })
}

const compute = async() => {
    var {ids, authorName} = await author();
    var {authors, counts} = await transaction();
    let total = 0;
    let arrAuthorPublished = { name: [], totalCount: [] }
    for(let x = 0; x < counts; x  ){
        if(ids == authors){
            arrAuthorPublished.name.push(authorName);
            arrAuthorPublished.totalCount.push(total = total   1);
        }
    }
    return arrAuthorPublished;
}

CodePudding user response：

I think you are trying to accomplish something like this:

const ids = [440944522, 440936792, 440936202, 440930072];
const authors = [440944522, 440936792, 440936202, 440930072];

const countMatches = (id, authors) => authors.filter(author=>author===id).length;

const totals = [];

for(let i = 0; i < ids.length; i  ){
  totals.push(countMatches(ids[i], authors))
}

CodePudding user response：

.filter() one array and compare:

arrA.filter(a => arrB.includes(a));

Then get the count by .length

const obj = {
  arrA: [440944522, 440936792, 440936202, 440930072],
  arrB: [440944522, 440936792, 440936202, 440930071]
};

const idTotal = obj.arrA.filter((a, i) => obj.arrB.includes(a));
console.log(idTotal.length);

let arrAuthorPublished = { name: [], totalCount: [] }
for(let x = 0; x < counts; x  ){
    for (let y = 0; y < ids.len; y  ){
        if(ids[y] != authorsid[y]){
            console.log("fail")
        } else {
            arrAuthorPublished.name.push(authorName)
            arrAuthorPublished.totalCount.push(total = total   1);
        }
    }
