Answer 1

Example I have a students list as below :

$scope.students = [  
   { name: 'Hai', age: 25, gender: 'boy' },  
   { name: 'Hai', age: 30, gender: 'girl' },  
   { name: 'Ho', age: 25, gender: 'boy' },  
   { name: 'Hoan', age: 40, gender: 'girl' },  
   { name: 'Hieu', age: 25, gender: 'boy' }  
 ];  

I want to filter students via gender to be boy and filter by name of them.

The first I create a function named "filterbyboy" as following:

$scope.filterbyboy = function (genderstr) {  
   if ((typeof $scope.search === 'undefined')||($scope.search === ''))  
     return (genderstr = "")  
   else  
    return (genderstr = "boy");  
 };  

Explaination: if not filter name then display all students else filter by input name and gender as 'boy'
