Finding wrong behaviour from filter resut

I am trying to find the projects by its project ids. For that, I am using this filter method:

$scope.filteredPro = $filter('filter')( project.ProjectSummaryFilter, {"ProjectId" : "1" } );

But when I am getting the result, the project which has the id as 1 and 10 appears as well.. in this case if I make my filter using only by 10 like this:

$scope.filteredPro = $filter('filter')( project.ProjectSummaryFilter, {"ProjectId" : "10" } );

I am exactly getting the result from the id of 10. How can fix this?

Why am I getting a result including the project which has the id of 10 as well when I filter by 1?

Solution

  • for an exact match, you should try:

    $scope.filteredPro = $filter('filter')( project.ProjectSummaryFilter, {"ProjectId" : "1" },true );

    $filter('filter')(array, expression, comparator)

    where expression:

    Object: A pattern object can be used to filter specific properties on objects contained by array. For example {name:"M", phone:"1"} predicate will return an array of items which have property name containing "M" and property phone containing "1"

    where comparator value:

    true: A shorthand for function(actual, expected) { return angular.equals(actual, expected)}. This is essentially strict comparison of expected and actual.
