如何使用orderBy并过滤其他JSON对象中的某些内容

Question

How can I filter and search the item name when the item details are coming from another JSON object ?

Demo: http://codepen.io/anon/pen/GjAxKX

The rest of the filter and orderBy working fine, but I couldn't find solution for the item part for orderBy and filter

Answer 1

first modify the data:

function preprocess(expenses) {
  for (var i = 0; i < expenses.length; i++) {
    var expense = expenses[i];
    expense.item = $scope.theItems[expense.item].name;
    expenses[i] = expense;
  }
  return expenses;
}

$scope.expenses = preprocess($scope.expenses);

then modify the html: <td>{{expense.item}}</td>
