Question

I’ve three strings.

var ids = "1*2*3";
var Name ="John*Brain*Andy";
var Code ="A12*B32*C38";

I want to create a JavaScript object of it.

Answer 1

A JSON object is just a string, so it would be:

var json = '{"ids":"'+ids+'","Name":"'+Name+'","Code":"'+Code+'"}';

If you want the strings converted into string arrays:

var json = '{"ids":["'+ids.replace(/\*/g,'","')+'"],"Name":["'+Name.replace(/\*/g,'","')+'"],"Code":["'+Code.replace(/\*/g,'","')+'"]}';

If you are not at all looing for JSON, but in fact a Javascript object, it would be:

var obj = {
  ids: ids.split('*'),
  Name: Name.split('*'),
  Code: Code.split('*')
};

Based on your description “I want first item of the array to be having three props i.e. Id, name and code with values 1,John, A12 respectively.” it would however be completely different:

var Ids = ids.split('*'), names = Name.split('*'), codes = Code.split('*');
var arr = [];
for (var i = 0; i < Ids.length; i++) {
  arr.push({ Id: Ids[i], name: names[i], code: codes[i] });
}

And if you want that as JSON, it would be:

var Ids = ids.split('*'), names = Name.split('*'), codes = Code.split('*');
var items = [];
for (var i = 0; i < Ids.length; i++) {
  items.push('{"Id":"'+Ids[i]+'","name":"'+names[i]+'","code":"'+codes[i]+'"}');
}
json = '[' + items.join(',') + ']';

(Note: The last code only works properly when the strings doesn’t contain any quotation marks, otherwise they have to be escaped when put in the string.)
