To display results of 2 ng-repeats alternately

manishk Published in 2018-01-12 17:53:45Z

I need the values returned from {{compNames}} and {{compDesc}} to print alternately, like a top-down stack. But with the 2 ng-repeats I'm not able to get it in that format.

<div class="title">
            <td class="comp-names" ng-repeat="compNames in $ctrl.data.compNames track by $index">{{compNames}}</td>
            <td class="comp-desc" ng-repeat="compDesc in $ctrl.data.compDesc track by $index">{{compDesc}}</td>

If I print out {{$ctrl.data}}, I get the following-

"details": {
    "comp": { 
        "id": "12345",
        "company_name": "Google",
        "date_created": "2018-01-10 18:03:27",
"compNames": ["five","nine","twelve"],
"compDesc": [" String combinations"," String combinations"," String manipulation to eval"]

I checked a similar thread and tried to do something like the following but I think it's the wrong approach and doesn't work for me (hence I have given the $ctrl.data output as well)-

<div ng-repeat="data in $ctrl.data">

One solution is to do a zip-operation on the two arrays beforehand in your controller and then iterate over the resulting array.

Something like this:

ctrl.combined = ctrl.data.compNames.map(function(value, index){
    return { name: value, desc: ctrl.data.compDesc[index] };

and then iterate over it like this:

<tr ng-repeat="comp in $ctrl.combined track by $index">
    <td class="comp-names">{{comp.name}}</td>
    <td class="comp-desc">{{comp.desc}}</td>

or in case you had something else in mind when you said alternating, you can do something like this:

<tr ng-repeat-start="comp in $ctrl.combined track by $index">
    <td class="comp-names">{{comp.name}}</td>
<tr ng-repeat-end>
    <td class="comp-desc">{{comp.desc}}</td>

Beware that you need to add extra logic to the map-function, in case you expect the two arrays to be of different lengths. But based on your data, it doesn't seem like that'll be an issue.

if length of your compNames is equal to compDesc, you can use length in your ng-repeat to iterate length many times


$scope.getNumber = function() {
    return new Array( $scope.data.compNames.length);


<div ng-repeat="i in getNumber() track by $index">
