Match IDs and subIDs with looped AJAX and Relate them with Neo4j

Question

OK title may be not clear, but here is the problem:
I have an array where the IDs of some main-equipment data is stored. Each equipment entity has some child-equipment with their subIDs.
I make an AJAX call to server to retrieve subIDs of each child-equipment by looping the IDs of main-equipment. Later I want to map the individual main-equipment ID with its child-equipment IDs and assign a relationship between them with Neo4j graph database. Following what I have came up:

for (var j in mainIDs) {
   $.ajax({
     type: "GET",
     url: "https://someserver.com/api/v1/equipment/"+mainIDs[j]+"/childequipments",
     dataType: "json",
     cache: false
       }).done(function (result) {
           // get ID number of child equipments
           var results = result.content;
           for (var i = 0; i < results.length; i++) {
             $.ajax({
                type: "POST",
                url: "http://localhost:7474/db/data/transaction/commit",
                accepts: {json: "application/json"},
                dataType: "json",
                contentType: "application/json",
                data: JSON.stringify({"statements": [{"statement": "START n=node(*), m=node(*) WHERE has (n.id) and has(m.id) and n.id ='"+mainIDs[j]+"' and m.id='"+results[i].id+"' MERGE (m)-[:BELONGS_TO]->(n)"}]}),
                success: function(result) {
                  console.log('successful');
           }

What I am in this query to reach sth similar like following logic:

Equipment 11 has child-equipment 20
Equipment 11 has child-equipment 21
Equipment 11 has child-equipment 22
Equipment 13 has child-equipment 40
Equipment 13 has child-equipment 41

But I get only one main-equipment ID (usually first) with all child-equipment ID instead of each of the main-equipmentID. How can I reach the above result? Thanks.

You is using forEach when you do for (var j in mainIDs) {. In this block:

+mainIDs[j]+

or you can only pass j, like +j+, or you can alter the for method:

for ( var j=0 ; j <= mainIDs ; j++) {

and then you will be able to +mainIDs[j]+

Thanks for your reply. I tried your solution, asynchronous, loop closure,etc. but still have the problem.. – ylcnky Sep 23 '16 at 21:45

Hey. It was a typo from other variables caused the problem. But your suggested helped for another issue. Thanks, accepted. – ylcnky Sep 24 '16 at 13:40
