I want to set my angular chosen with default value from my response. also my Angular chosen dropdown values also coming from AJAX response. I tried ng-init and pointing the value with respect to index. But no luck.
HTML
<select ng-init="model.country = cities[currentLocationIdx]"
chosen ng-model="model.country"
ng-options=" cities.name for cities in cities" required>
<option value="">Select a Location</option>
</select>
JS:
$scope.model.country = "Bangalore";
$scope.currentLocationIdx = $scope.cities.findIndex( city => city.name === $scope.model.country );
JSON:
[
{
"name": "South Andaman"
},
{
"name": "Nicobar"
},
{
"name": "Adilabad"
},
{
"name": "Anantapur"
},
{
"name": "Chittoor"
},
{
"name": "East Godavari"
},
{
"name": "Bangalore"
}
]
You just need to declare your variable as obj in controller like this:
$scope.model = {};

Try this below updated code. Its working at my end with chosen library.

I am trying to set height of the ui-grid to be the size of 3 rows. I went through the ui-grid documentation and it contains something like minRowsToShow but there is no equivalent property to maxRowsToShow or something similar.
I am trying to avoid setting a css fixed height manually on the grid.
var app = angular.module('app', ['ui.grid', 'ui.grid.edit']);
app.controller('MainCtrl', ['$scope', '$http', function ($scope, $http) {
$scope.gridOptions = {
columnDefs: [
{ field: 'name' },
{ field: 'amount', name: 'Number', cellFilter: 'fractionFilter' },
{ field: 'amount', name: 'Currency', cellFilter: 'currencyFilter:this' }
]
};
$scope.gridOptions.data = [
{
"name": "Claire",
"amount": 21.9015,
"currency": "euro"
},
{
"name": "Fitzpatrick",
"amount": 41.6352,
"currency": "pound"
},
{
"name": "Ericka",
"amount": 31.4228,
"currency": "pound"
},
{
"name": "Navarro",
"amount": 2.1944,
"currency": "dollar"
},
{
"name": "Cherie",
"amount": 31.9234,
"currency": "dollar"
},
{
"name": "Cobb",
"amount": 45.5756,
"currency": "pound"
}
];
}])
.filter('fractionFilter', function () {
return function (value) {
return value.toFixed(0);
};
})
.filter('currencyFilter', function () {
var currencyMap = {
'dollar': '$',
'pound': '£',
'euro': '€'
};
return function (value, scope) {
return currencyMap[scope.row.entity.currency] + value.toFixed(2);
};
})
;

My desired result is this. Is there a way of achieving this with existing ui-grid options/properties?
You can use pagination and disable the pagination control:
$scope.gridOptions1 = {
enableHorizontalScrollbar: 0,
enableVerticalScrollbar: 0,
paginationPageSizes: [3],
paginationPageSize: 3,
enablePaginationControls: false,
columnDefs: [
...
]
};

I am trying to displaying country names from json object. json data looking collection of array object, this object using ng-repeat iterating that json data and displaying into select box. i tried bellow code.
Json
----
$scope.countries = [
{
"AT": "Austria"
},
{
"CI": "Côte d'Ivoire"
},
{
"CG": "Congo"
},
{
"SV": "El Salvador"

]
html
----
<select ng-model="counryNames" >
<option ng-repeat="(key,country) in countries" value="{{key}}">{{country[key]}}</option>
</select>
Change your ng-repeat as, you should access the key of countries not country
<option ng-repeat="(key, value) in countries" value="{{key}}">{{countries[key]}}</option>
DEMO
angular.module("myapp", [])
.controller("MyController", function($scope) {
$scope.countries = [{

I have a list of name's and id's. I have displayed it with ng-repeat property. I want to show the corresponding id's along with the name in 1 second on its click.
$scope.showFn = function() {
$scope.showPopup = true;
$timeout(function(){
console.log("timeout");
$scope.showPopup = false;
}, 1000);
};
I have created a plunker https://plnkr.co/edit/kvkgwp60Bxq2MrHrr5Rr?p=preview
Now showing all the id's in a single click. Please help. Thanks.
Try with below in HTML:
<!DOCTYPE html>
<html ng-app="app">
<head>
<script data-require="angular.js#*" data-semver="1.3.0-beta.5" src="https://code.angularjs.org/1.3.0-beta.5/angular.js"></script>
<link rel="stylesheet" href="style.css" />

</head>
<body ng-controller="main">
<ul>
<li ng-repeat="item in items">
{{item.name}}
<span ng-show="showPopup && item.id == shownId">{{item.id}}</span>
</li>
</ul>
</body>
</html>
Controller will be like below:
var app = angular.module('app', [])
.controller('main', function($scope, $timeout) {
$scope.items = [{
"name": "one",
"id": "1"
}, {
"name": "two",
"id": "2"

"name": "three",
"id": "3"
}, {
"name": "four",
"id": "4"
}, {
"name": "five",
"id": "5"
}, {
"name": "six",
"id": "6"
}, {
"name": "seven",
"id": "7"
}]
$scope.showFn = function(Item) {
$scope.shownId = Item;
$scope.showPopup = true;
$timeout(function() {
console.log("timeout");
$scope.showPopup = false;
}, 1000);
};
});
I'm trying to filter a nested array of objects with my own objects, by idSubject. But I'm not getting the right result.
I have articles (which have subjects)
And a array of objects (which are the subjects I want to filter the articles with)
Data looks like this:
So I'm trying to filter the array of articles by its subjects.
I tried the following:
<div class="panel panel-default"
ng-repeat="searchArticle in searchArticles | filter: {subjects: filterSubjects} as articleSearchResult">
So filterSubjects is the second screenshot and SearchArticles is the first screenshot.
Without much luck.
Hope you can help, please tell me if things are still unclear.
This custom filter will help you.
Example : http://plnkr.co/edit/jMizCLxPH6DtDA5wL15Q?p=preview
HTML:
<body ng-app="myApp">
<div ng-controller="MainCtrl">
<h2>Select Subjects</h2>
<div ng-repeat="subject in subjects">
<label>
<input type="checkbox" ng-model="filterSubjects[subject.id]" ng-true-value="'{{subject.id}}'" ng-false-value="''">{{subject.name}}</label>
</div>
<h2>Filtered Articles</h2>
<div ng-repeat="searchArticle in searchArticles | subjectFilter:filterSubjects">{{searchArticle.name}}</div>
</div>
</body>
JS:
var app = angular.module('myApp', []);
app.controller('MainCtrl', function($scope) {
$scope.searchArticles = [{
"name": "Article1",
"sid": "1"
}, {
"name": "Article2",
"sid": "1"
}, {
"name": "Article3",
"sid": "2"
}];
$scope.subjects = [{
"name": "Subject1",
"id": "1"
}, {
"name": "Subject2",
"id": "2"
}];
$scope.filterSubjects = [];
});
app.filter('subjectFilter', function() {
return function(articles, filterSubjects) {
filtered = articles.filter(function(e){return filterSubjects.indexOf(e.sid) >= 0},filterSubjects);
return filtered;
}
});
if you want to filter based on object :
var app = angular.module('myApp', []);
app.controller('MainCtrl', function($scope) {
$scope.searchArticles = [{
"name": "Article1",
"sid": "1"
}, {
"name": "Article2",
"sid": "1"
}, {
"name": "Article3",
"sid": "2"
}];
$scope.subjects = [{
"name": "Subject1",
"id": "1"
}, {
"name": "Subject2",
"id": "2"
}];
$scope.filterSubjects = [{
"name": "Subject1",
"id": "1"
}, {
"name": "Subject1",
"id": "2"
}];
});
app.filter('subjectFilter', function() {
return function(articles, filterSubjects) {
var sFiltered = [];
for (var i = 0; i < filterSubjects.length; i++) {
sFiltered.push(filterSubjects[i].id);
}
var filtered = articles.filter(function(e) {
return sFiltered.indexOf(e.sid) >= 0;
}, sFiltered);
return filtered;
}
});
I'm trying to populate a Select getting data from a webapi using ng-options.
Basically, my webapi returns the following JSON:
{
"items":[
{
"name":"X",
"id":1
},
{
"name":"Y",
"id":2
}
]
}
And I Need to generate options in a select displaying the name property, but with the id as value.
The problem is that I can't display my options using ng-options. Here's what I'm trying:
<html ng-app='app'>
<head>
<title>angular</title>
</head>
<body ng-controller='DemoCtrl'>
<select ng-model="selectedTestAccount" ng-options="option.name for option in testAccounts">
<option value="">Select Account</option>
</select>
<script src='https://code.angularjs.org/1.5.0-rc.0/angular.min.js'></script>
<script>
angular.module('app', []).controller('DemoCtrl', function ($scope, $http) {
$scope.selectedTestAccount = null;
$scope.testAccounts = [];
$http({
method: 'GET',
url: '/api/values',
data: {}
}).success(function (result) {
console.log(result);
$scope.testAccounts = JSON.parse(result.items);
});
});
</script>
</body>
</html>
I hope this helps you
angular.module("app", []);
angular.module("app").controller("ctrl", function($scope) {
$scope.testAccounts = [];
var youJson = [
{ "items": [{ "name": "X", "id": "your value for X" }, { "name": "Y", "id": "your value for Y" }] },
{ "items": [{ "name": "A", "id": "your value for A" }, { "name": "B", "id": "your value for B" }] }
];
angular.forEach(youJson, function(items) {
angular.forEach(items.items, function(item) {
$scope.testAccounts.push(item);
});
});
console.log($scope.testAccounts);
});
