function CustomerController($scope) {
    $scope.list = [
        { ID:"1", FirstName: 'Bharani', LastName: 'Kumar', City: 'New Delhi' },
        { FirstName: 'Pat', LastName: 'J', City: 'Paris' },
        { FirstName: 'John', LastName: 'P', City: 'Washington DC' },
        { FirstName: 'Max', LastName: 'X', City: 'London' }
    ];
 
	$scope.delCustomer = function (FirstName) {
	     var index = $scope.list.indexOf(FirstName);
		 $scope.list.splice(index, 1); 
    };

您必须发送记录而不是仅仅将FirstName发送到函数，它将尝试将第一个名称与记录数组匹配，它将始终返回-1作为索引。

function CustomerController($scope) {
    $scope.list = [
        { ID:"1", FirstName: 'Bharani', LastName: 'Kumar', City: 'New Delhi' },
        { FirstName: 'Pat', LastName: 'J', City: 'Paris' },
        { FirstName: 'John', LastName: 'P', City: 'Washington DC' },
        { FirstName: 'Max', LastName: 'X', City: 'London' }
    ];
 
	$scope.delCustomer = function (FirstName) {
	     var index = $scope.list.indexOf(FirstName);
		 $scope.list.splice(index, 1); 
    };
}
