I have a pair of lists that are the same length.
My goal is to utilize AngularJS to generate a repeated UI table.
<tr ng-repeat="pair in pairs ..>
For example, with lists [1,2,3,4] and [a,b,c,d]:
Table:
1 row: 1 a
2 row: 2 b
3 row: 3 c
4 row: 4 d
How can I achieve this functionality?
Should I merge the two lists and then iterate over them in Angular? Or is there another method involving nested loops?
A great approach is to merge both arrays into a single array by doing the following:
var $scope.combinedArray = [];
for (var i = 0; i < firstArray.length; i++) {
$scope.combinedArray.push({number: firstArray[i], letter: secondArray[i]});
}
Then in your HTML:
<tr ng-repeat="item in combinedArray>
<td>
{{item.number}} - {{item.letter}}
</tr>
</tr>
ng-repeat on list1.{{}})$index as an index to retrieve values from another array Here is the solution
angular.module('app',[]).controller('ctrl', function($scope){
$scope.list1 = [1,2,3,4];
$scope.list2 = ["a","b","c","d"];
})<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.9/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
<div ng-repeat="list in list1">
{{list}} row : {{list}} {{list2[$index]}}
</div>
</div>To retrieve values from another array, you can utilize the iterator's '$index' in AngularJS.
//controller
$scope.items = [10, 20, 30];
$scope.otherItems = ['apple', 'banana', 'cherry'];
//template
<tr ng-repeat="item in items">
<td>{{ item }}</td>
<td>{{ otherItems[$index] }}</td>
</tr>
It is important to note that this method will only work if both arrays have the same length.
