Experiencing a lack of defined information when using a service

After spending hours trying to figure it out, I have a question.

The issue here is that the data is being received faster than my services can load.

gen-service

function genEmpId() {
settingsService.getSettings().then(function (data) {
    var comId = data.data[0].companyId;
    console.log(comId);
    var test = comId + ' - ';
    return test;
});}

controller

function genId() {
   var data = genService.genEmpId();
   console.log(data); // The data is retrieved too quickly; how can I implement a callback?
}

When my controller loads, it calls the service but I'm getting an undefined return value.

Answer №1

Here is a suggestion for your code. Remember to include a return statement in your function and be aware that it is an asynchronous call, so you need to wait for it to finish.

// gen-service

function generateEmployeeId() {
  return settingService.getSettings().then(function (data) {
    var companyId = data.data[0].companyId;
    console.log(companyId);
    var result = companyId + ' - ';
    return result;
  });
}

// controller

function generateId() {
  var data = genService.generateEmployeeId().then(function (data) {
    console.log(data);
  })
}
