I'm developing a page where I need to show some boxes (using ng-repeat
) that contains info of channels and where it will be shown (which are cities).
The problem I am facing is when I repeat the second ng-repeat
:
<table class="table table-condensed" ng-init="nitsCh = [objsCh[$index].nit]">
This should get the $index of first ng-repeat and create a new array with the places the channels will be shown. And it does exactly that. But, when I apply the second ng-repeat using this array, it doesn't work properly.
Said that my html looks like this (PS: I need to use the index value instead of objCh.name
because I place these boxes into columns)
<div class="box box-solid box-default" ng-repeat="(indexO, objCh) in objsCh track by indexO" ng-if="indexO%4==0 && indexO<=10">
<div class="box-header">
<div class="pull-left">
<img src="dist/img/channels/{{ objsCh[indexO].pic }}" data-toggle="tooltip" title="" data-original-title="Alterar logo do canal">
<h3 class="box-title">{{ objsCh[(indexO)].name }}</h3>
</div>
<div class="box-tools pull-right">
<button class="btn btn-box-tool" data-toggle="tooltip" title="" data-original-title="Adicionar ou Remover NIT"><i class="fa fa-plus"></i></button>
</div>
</div>
<div class="box-body">
<table class="table table-condensed" ng-init="nitsCh = [objsCh[indexO].nit]">
<tbody>
<tr>
<th style="width: 10px">#</th>
<th>Nit</th>
</tr>
<tr ng-repeat="(indexN,nitCh) in nitsCh track by indexN">
<td>{{ objsCh[(indexO + 1)].nit[indexN].num }}</td>
<td>{{ objsCh[(indexO + 1)].nit[indexN].name }}</td>
</tr>
</tbody>
</table>
</div>
</div>
The JS file looks like this:
var app = angular.module('appApp', []);
app.controller('ctrlApp', function($scope, $http) {
var url = "includes/exibChNit.php";
$http.get(url).success(function(response) {
all = response;
$scope.objsCh = all.channels;
});
});
And the json file (that php create) looks like this:
{
"channels": [{
"id": "1",
"sid": "1",
"name": "Channel",
"pic": "channel.jpg",
"crc32": "A1g423423B2",
"special": "0",
"url": "",
"key": "",
"type": "",
"city": [{
"num": "1",
"name": "S�o Paulo"
}, {
"num": "2",
"name": "Rio de Janeiro"
}]
}, {
"id": "2",
"sid": "2",
"name": "CHannel 1",
"pic": "channel.jpg",
"crc32": "A1F5534234B2",
"special": "0",
"url": "",
"key": "",
"type": "",
"city": [{
"num": "1",
"name": "S�o Paulo"
}, {
"num": "2",
"name": "Rio de Janeiro"
}]
}]
}
When I try this it works:
<table class="table table-condensed" ng-init="nitsCh = [objsCh[($parent.$index + 1)].nit]">
But I can't make it this way because the json nodes will be dynamic.
Thanks in advance!
NEST TWO ng-repeatThe first ng-repeat in the tr tag will create the rows and the second one in the td tag will create one column per element in the collection. By using one ng-repeat for the row and an other for the column, the rows and the columns of your table is now driven by a subset.
And you should consider using ng-repeat with pagination. You can consider using transclusion inside a custom directive, to achieve the behavior you are looking for without using ng-repeat.
ng-options is the directive which is designed specifically to populate the items of a dropdown list. One major advantage using ng-options for the dropdown is, it allows us to pass the selected value to be an object. Whereas, using ng-repeat the selected value can only be string.
However, some directives, such as ng-controller and ng-repeat, create new child scopes and attach the child scope to the corresponding DOM element.
ng-repeat
's create their own $scope
.
So, for the inner ng-repeats, you have access to $parent.$index
, where $parent
is the parent scope of the current repeat block.
For ex:
<ul ng-repeat="section in sections">
<li>
{{section.name}}
</li>
<ul>
<li ng-click="loadFromMenu($parent.$index)" ng-repeat="tutorial in section.tutorials">
{{tutorial.name}}
</li>
</ul>
</ul>

(simplified from this answer passing 2 $index values within nested ng-repeat)
