Angular Filter控制台错误消息

Question

这个选择框正在做它应该做的事情，但由于某种原因它不再工作了。 选择框显示作为项目经理的员工。当我选择一个时，它会用它更新输入框。

过滤

app.filter('filterEmployees', function() {
 return function (input) {
console.log('input: ', input);
var output = [];
if (!input instanceof Array) {
  console.log('error');
  return output;
  }
  // for all TESPM's
   input.forEach(function (tespm) {
  var employees = tespm.Employees; 
  if (!employees instanceof Array) {
    console.log('error');
    return output;
  }
  // for all employees
  employees.forEach(function (employee) {
    // filter
    if (employee.EmployeeIsPM) {
      output.push(employee.EmployeeFirstName + ' ' + employee.EmployeeLastName);
    }
  });
});
console.log('output: ', output);
return output;
   };
});

查看

<div class="input-group">
   <span class="input-group-addon">J. TESPM</span>
   <input style="width:150px" ng-model="TESPM" class="form-control" type="text">
   <span class="input-group-addon">J. TESPM</span>
    <select class="form-control" ng-options="empl for empl in jobArray|filterEmployees" ng-model="TESPM">
          <option value="" disabled>Select</option>
    </select>
 </div>
