AngularJS Scope don't call elements

AngularJS Scope don't call elements - arrays

Hi guys this exercise with scopes don't run,
View:
<body ng-controller="marcasController">
<ul>
<li ng-repeat="todo in marcas">
{{todo.nombre}}
<ul>
<li ng-repeat="tipo in todo.modelo">{{tipo.nombre}}</li>
</ul>
</li>
</ul>
</body>
Controller:
app.controller('marcasController', ['$scope', function($scope) {
$scope.marcas =
[{
"marcas": [
{
"marca": "Chevrolet",
"modelo": [
{
"nombre": "Aveo",
"image": "images/aveo.jpg",
"modelo": "2000-2014",
"tab": "aveo"
},
{
"nombre": "Captiva",
"image": "images/captiva.jpg",
"modelo": "2000-2014",
"tab": "captiva"
}
]
}
]
}];
}])
Example
please how use scopes to call objects

Given that data structure you should be doing it like this:
<ul>
<li ng-repeat="todo in marcas[0].marcas">
{{todo.marca}}
<ul>
<li ng-repeat="tipo in todo.modelo">{{tipo.nombre}}</li>
</ul>
</li>
</ul>
Example
Notice that $scope.marcas is an Array of objects that contains just one element, that element has only one attribute: marcas which is another Array...
Maybe you wanted that data structure to be like this instead:
$scope.marcas =[
{
"marca": "Chevrolet",
"modelo": [
{
"nombre": "Aveo",
"image": "images/aveo.jpg",
"modelo": "2000-2014",
"tab": "aveo"
},
{
"nombre": "Captiva",
"image": "images/captiva.jpg",
"modelo": "2000-2014",
"tab": "captiva"
}
]
}
];
In that case, the correct syntax for your view would be:
<ul>
<li ng-repeat="todo in marcas">
{{todo.marca}}
<ul>
<li ng-repeat="tipo in todo.modelo">{{tipo.nombre}}</li>
</ul>
</li>
</ul>

Update list of child items in data set using ng-repeat and index value passed from navigation

I have displayed a list of items in my data set using the ng-repeat as below.
<li ng-repeat="item in adults[1].children">
{{item.childName}}
</li>
What I would like to do is HOW TO dynamically update the list using navigation such as this to show the other child items -
<li ng-click="updateList(1)">First kids</li>
<li ng-click="updateList(2)">Second group of kids</li>
<li ng-click="updateList(3)">Third group of kids</li>
dataset
$http.get('data/parents-data.json')
.then(function(res) {
$scope.adults= res.data;
});
[
{
"parentName": "Jim",
"age": "32",
"sex": "M",
"children": [
{"childName": "Jennifer"},
{"childName": "Timmy"}
]
},
{
"parentName": "Barbara",
"age": "29",
"sex": "F",
"children": [
{"childName": "Oliver"},
{"childName": "Henry"},
{"childName": "Jane"}
]
},
{
"parentName": "Sue",
"age": "40",
"sex": "F",
"children": [
{"childName": "William"},
{"childName": "Robyn"},
{"childName": "Sarah"}
]
}
]
I'm really stumped as to how to get the updateList function to return the index back to the the ng-repeat
I tried
$scope.updateList = function(val) {
return adults[x].children;
}
With
<li ng-repeat="item in updateList()>
{{item.childName}}
</li>
But this obviously didn't work. I just can't get this clear in my head. Maybe I'm doing this wrong. Any help at all greatly appreciated : )

You just have to create a new $scope variable and update it on ng-click to change the list of childrens.
//Default set of children
$scope.childrens=$scope.adults[0].children;
//Update childrens variable on click
$scope.updateList = function(x) {
$scope.childrens=$scope.adults[x].children;
}
var app=angular.module("App",[]);
app.controller("AppCtrl",function($scope){
$scope.adults = [
{
"parentName": "Jim",
"age": "32",
"sex": "M",
"children": [
{"childName": "Jennifer"},
{"childName": "Timmy"}
]
},
{
"parentName": "Barbara",
"age": "29",
"sex": "F",
"children": [
{"childName": "Oliver"},
{"childName": "Henry"},
{"childName": "Jane"}
]
},
{
"parentName": "Sue",
"age": "40",
"sex": "F",
"children": [
{"childName": "William"},
{"childName": "Robyn"},
{"childName": "Sarah"}
]
}
];
$scope.childrens=$scope.adults[0].children;
$scope.updateList = function(x) {
$scope.childrens=$scope.adults[x].children;
}
});

You can create a new variable on your $scope to keep track of which children to display. Then we could create a function to update this group. See below
In your controller
$scope.children = $scope.adults[0]; // Default to the first group
$scope.updateGroup = function(newGroupNumber) {
$scope.children = $scope.adults[newGroupNumber];
};
Then in your template:
<li ng-repeat="child in children>
{{child.childName}}
</li>
...
<li ng-click="updateGroup(1)">First kids</li>
<li ng-click="updateGroup(2)">Second group of kids</li>
<li ng-click="updateGroup(3)">Third group of kids</li>

AngularJS ng-repeat for a JSON contains String or an array of a same property

I'm having a JSON data namely $scope.family, it contains the family.name and optionally family.child
app.controller('test', function ($scope) {
$scope.family = [
{
"name": "Siva",
"child": [
{
"name": "Suriya"
},
{
"name": "Karthick"
}
]
},
{
"name": "Kumar",
"child": [
{
"name": "Rajini"
},
{
"name": "Kamal"
},
{
"name": "Ajith"
}
]
},
{
"name": "Samer",
"child": "Ranjan"
},
{
"name": "Mahesh",
"child": "Babu"
},
{
"name": "Joseph"
}
];
});
Cases:
If family.child has one child then the name is directly assign as a string
If family.child has more than one child then the name is assign as a array of string with the property family.child.name
If family.child doesn't in the collection just show the family.name
My Expected Output UI is
Siva
Suriya
Karthick
Kumar
Rajini
Kamal
Ajith
Samer
Ranjan
Mahesh
Babu
Joseph
My HTML Source Code (I Can't able to get the expected output from this code)
<ul>
<li ng-repeat="member in family">
{{ member.name }}
<div class="liststyling" ng-if="member.child.length > 0">
<ul>
<li ng-repeat="chdMember in member.child>
{{ chdMember.name }}
</li>
</ul>
</div>
</li>
</ul>
Kindly assist me...

Please refer the fiddle here. You need some changes in the model and loop with the new modified model - newFamily instead of family.
HTML:
<div ng-app="app" ng-controller="test">
<ul>
<li ng-repeat="member in newFamily">
{{ member.name }}
<div class="liststyling" ng-if="member.child.length > 0">
<ul>
<li ng-repeat="chdMember in member.child track by $index">
{{ chdMember.name }}
</li>
</ul>
</div>
</li>
</ul>
</div>
JS:
var app = angular.module('app', []);
app.controller('test', function ($scope) {
$scope.family = [
{
"name": "Siva",
"child": [
{
"name": "Suriya"
},
{
"name": "Karthick"
}
]
},
{
"name": "Kumar",
"child": [
{
"name": "Rajini"
},
{
"name": "Kamal"
},
{
"name": "Ajith"
}
]
},
{
"name": "Samer",
"child": "Ranjan"
},
{
"name": "Mahesh",
"child": "Babu"
},
{
"name": "Joseph"
}
];
$scope.newFamily = [];
angular.forEach($scope.family, function (v, k) {
var existingChildArray = v.child;
var newChildArray = [];
if (!angular.isArray(v.child) && v.child) {
newChildArray.push({ 'name': v.child });
}
var addChild = newChildArray.length > 0 ? newChildArray : existingChildArray;
$scope.newFamily.push({ 'name': v.name, 'child': addChild });
});
});

Try this for your actual output.
<ul>
<li ng-repeat="member in family">
{{ member.name }}
<div class="liststyling">
<ul>
<li ng-repeat="chdMember in member.child">
{{ chdMember.name }}
</li>
</ul>
</div>
</li>
</ul>
$scope.family = [
{
"name": "Siva",
"child":
[
{
"name": "Suriya"
},
{
"name": "Karthick"
}
]
},
{
"name": "Kumar",
"child": [
{
"name": "Rajini"
},
{
"name": "Kamal"
},
{
"name": "Ajith"
}
]
},
{
"name": "Samer",
"child": [{name:"Ranjan"}]
},
{
"name": "Mahesh",
"child": [{name:"Babu"}]
},
{
"name": "Joseph",
"child": []
}
];

You can add the following method to your controller
$scope.isArray = function(obj) {
return angular.isArray(obj);
}
and update the markup as
<li ng-repeat="member in family">
{{ member.name }}
<div class="liststyling">
<ul ng-if="isArray(member.child)">
<li ng-repeat="chdMember in member.child">
{{ chdMember.name }}
</li>
</ul>
<ul ng-if="member.child && !isArray(member.child)">
<li>
{{ member.child }}
</li>
</ul>
</div>
</li>
This should do, I think.

Even though #MarcNuri provided a good answer. But if you are not changing the data pattern you can use this also.
HTML
<ul>
<li ng-repeat="member in family">
{{ member.name }}
<div class="liststyling" ng-if="isArray(member.child) && member.child.length > 0">
<ul>
<li ng-repeat="chdMember in member.child">
{{ chdMember.name }}
</li>
</ul>
</div>
<div class="liststyling" ng-if="!isArray(member.child) && member.child.length > 0">
<ul>
<li>
{{ member.child}}
</li>
</ul>
</div>
</li>
</ul>
JS
app.controller('test', function ($scope) {
$scope.isArray = angular.isArray;
$scope.family = [
{
"name": "Siva",
"child": [
{
"name": "Suriya"
},
{
"name": "Karthick"
}
]
},
{
"name": "Kumar",
"child": [
{
"name": "Rajini"
},

"name": "Kamal"

"name": "Samer",
"child": "Ranjan"
},
{
"name": "Mahesh",
"child": "Babu"
},
{
"name": "Joseph"
}
];
});
just notice $scope.isArray = angular.isArray; in js.Find plank HERE

Here is a simple running version of your code JSFiddle (not the best coding practices)
Keep in mind that you should use at least AngularJS 1.1.15 version at least to use ng-if.
You should simply tidy up your script a little and it'll work:
HTML:
<body ng-app="myApp">
<div ng-controller="ctrl">
<ul>
<li ng-repeat="member in family">
<h2>
{{ member.name }}
</h2>
<div class="liststyling" ng-if="member.child.length > 0">
<ul>
<li ng-repeat="chdMember in member.child">
{{ chdMember.name }}
</li>
</ul>
</div>
</li>
</ul>
</div>
</body>
Javascript:
var app = angular.module('myApp',[]);
app.controller('ctrl', MyCtrl);
function MyCtrl($scope) {
$scope.family = [
{
"name": "Siva",
"child": [
{
"name": "Suriya"
},
{
"name": "Karthick"
}
]
},
{
"name": "Kumar",
"child": [
{
"name": "Rajini"
},
{
"name": "Kamal"
},
{
"name": "Ajith"
}
]
},
{
"name": "Samer",
"child": [{name:"Ranjan"}]
},
{
"name": "Mahesh",
"child": []
},
{
"name": "Joseph"
}
];
}

Angular ng-repeat nested array

I've got this array
{
"menus": [
{
"id": "4",
"name": "Administrator",
"icon": "symbol-male",
"is_show": "1",
"sub_menus": [
{
"id": "6",
"admin_menu_id": "4",
"name": "Manage Admin Role",
"link": "admin-roles",
"is_show": "1"
},
{
"id": "5",
"admin_menu_id": "4",
"name": "Manage Administrator",
"link": "admins",
"is_show": "1"
}
]
}
]
}
How can I ng-repeat with the sub_menus properly with the menus?
I've tried
<ul>
<li ng-repeat="menu in menus">{{ menu.name }}
<ul>
<li ng-repeat="sub_menu in menu.sub_menus">{{ sub_menu.name}} </li>
</ul>
</li>
</ul>
But the sub_menus.name not shown when I repeat it.

Your html need to be something like below.
<ul>
<li ng-repeat="menu in menuItems.menus">{{ menu.name }}
<ul>
<li ng-repeat="sub_menu in menu.sub_menus">{{ sub_menu.name}} </li>
</ul>
</li>
</ul>
Have alook at this JSFiddle

Accessing the nested Arrays using ng-repeat in angularjs

JSFiddle
I'm not able to access the array images in the nested collection. Why am I not able to see any output?
The model:
var obj = [{
"id": "7",
"date": "1 Jan",
"images": ["507f42c682882", "507e24b47ffdb", "507e2aeca02d5", "507e2b19663a9"]
}, {
"id": "7",
"date": "1 Jan",
"images": ["507f42c682882", "507e24b47ffdb", "507e2aeca02d5", "507e2b19663a9"]
}];
This is the HTMl with ng-repeat:
<ul>
<li ng-repeat="img in item">
<br />
<li ng-repeat="img1 in img.images">{{img1}}</li>
</li>
</ul>
Can anyone point me to what I'm missing?

The problem is you are trying to repeat a list of li elements inside of a li element, which is invalid HTML. As such, angular will not render this.
Update your HTML to:
<ul>
<li ng-repeat="img in item">
<ul>
<li ng-repeat="img1 in img.images">{{img1}}</li>
</ul>
</li>
</ul>
