Create an a multi diemensional array from different variables in Javascript

Question

How do i create a multi-dimensional array from different javascript variables ?

For example, i have these three variables

var pdate = "|2019年12月26日|2019年12月26日|2019年12月26日"
var products_id = "3354|5009|61927"
var products_category = "ENERGETICS|CASIO|SEIKO" 

And i would like to transform them into this

var products_list = []
[0] = {pdate:"2019-12-26",products_id:"3354",products_category:"ENERGETICS"}
[1] = {pdate":"2019-12-26",products_id:"5009",products_category:"CASIO"}
[2] = {pdate:"2019-12-26",products_id:"61927",products_category:"SEIKO"}

Any ideas ?

Thanks

• daremachine: What you tried?
• Barmar: Use split() to split the strings into arrays. Then loop over them and create an array of objects.
• Barmar: Why does pdate have a delimiter at the beginning, but the other strings don't?
• Barmar: That's not a multidimensional array. It's a 1-dimensional array of objects.

Answer 1

You can use the function split to separate the datas:

var pdate = "2019-12-26|2019年12月26日|2019年12月26日";
var products_id = "3354|5009|61927";
var products_category = "ENERGETICS|CASIO|SEIKO";
var arrayPdate = getData(pdate);
var arrayProducts_id = getData(products_id);
var arrayProducts_category = getData(products_category);
var result = []
for (let i = 0; i < arrayPdate.length; i++) {
 let jsonObject = {
 pdate: arrayPdate[i],
 products_id: arrayProducts_id[i],
 products_category: arrayProducts_category[i]
 }
 result.push(jsonObject)
}
console.log(result);
function getData(c) {
 return c.split("|")
}

• daremachine: I think getData(c) is only redundant split wrapper leading for larger complexity IMO

You need use .split function on your string and then use loop with array index for others.

var pdate = "2019-12-26|2019年12月26日|2019年12月26日";
var products_id = "3354|5009|61927";
var products_category = "ENERGETICS|CASIO|SEIKO";
pdate = pdate.split('|');
products_id = products_id.split('|');
products_category = products_category.split('|');
let arr = [];
for(let i=0; i<pdate.length; i++) {
 arr.push({
 pdate: pdate[i],
 products_id: products_id[i],
 products_category: products_category[i] 
 });
}
console.log(arr);
