Fetch Child Table data from other DocType [Clientside]

[FlashKiller]

Managed it by myself:

frappe.call({
  method:"frappe.client.get_list",
  args: {
      doctype:"ManagerAccounts",
   filters:{
              user: frappe.session.user}
      },
  callback: function(r) {
   frappe.call({
       method: "frappe.client.get",
       args: {
           doctype: "ManagerAccounts",
           name: r.message[0].name
       },
       callback: function (ret){
           $(ret.message.account).each((index,element) => console.log(element.account));
           // Do things here
       }
   })
  }
})
