Using select value in ng-repeat
Right now I have to use the limitTo filter with the selected value, but I really want to use the selected value as the number of times the ng-repeat should run. But this value is an object, and ng-repeat expects an array.
So in theory it works. But ultimately all the information should generate this table.
Update: the code works, but instead of declaring a range [1,2,3,4,5,6]
(and applying a filter afterwards), I want to use a value factorSelection.value
that is an object while it expects an array.
var app = angular.module('application', []);
app.controller('mainCtrl', ['$scope', function($scope) {
$scope.factors = [
{value: '1', name: '1 factor'},
{value: '2', name: '2 factors'},
{value: '3', name: '3 factors'},
{value: '4', name: '4 factors'},
{value: '5', name: '5 factors'}
];
$scope.states = [
{value: '1', name: '1 state'},
{value: '2', name: '2 states'},
{value: '3', name: '3 states'},
{value: '4', name: '4 states'},
{value: '5', name: '5 states'}
];
}]);
.item {
padding: 10px;
border-bottom: 1px solid #999;
}

Got a response via another channel (Google+), will add it as a response with updated code.
Added functions to get the length and return these values as parameters.
This still ends up in conflict with various input fields, but this is something I can work on to fix and update once when done.
var app = angular.module('application', []);
app.controller('mainCtrl', ['$scope', function($scope) {
$scope.factors = [
{value: '1', name: '1 factor'},
{value: '2', name: '2 factors'},
{value: '3', name: '3 factors'},
{value: '4', name: '4 factors'},
{value: '5', name: '5 factors'}
];
$scope.states = [
{value: '1', name: '1 state'},
{value: '2', name: '2 states'},
{value: '3', name: '3 states'},
{value: '4', name: '4 states'},
{value: '5', name: '5 states'}
];
/*
* Get factor options
*/
$scope.getFactors = function(len){
return $scope.getOptions(len, $scope.factors);
}
/*
* Get state options
*/
$scope.getStates = function(len){
return $scope.getOptions(len, $scope.states);
}
/*
*
*/
$scope.getOptions = function(len, options){
if (len && len <= options.length ){
return options.slice(0, len);
}
}
}]);
.item {
padding: 10px;
border-bottom: 1px solid #999;
}
