I have a list of Subjects , which are used to populate
a group of checkboxes. And I have a list of SubjectIds,
where, the values of the Subjects match with a Subject Id , then
the checkbox will be checked.
For this The html code is:
<div ng-repeat="subj in Subjects">
<div ng-repeat="sub in SubjectIds">
<input type="checkbox" ng-model="subjectModel[subj.SubjectId]" ng-checked="subj.SubjectId==sub"/>{{subj.SubjectName}}
</div>
</div>
This code checks the desired checkboxes, but the checkboxes are repeated by the number of the items in SubjectIds.
You need a logic that checks if the index is in the given array. I suggest you use .indexOf() method for arrays. Here is an example:
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.Subjects = [
{"SubjectId":1,"SubjectName":"Name1"},
{"SubjectId":12,"SubjectName":"Name12"},
{"SubjectId":101,"SubjectName":"Name101"},
];
$scope.SubjectIds = [1, 101];
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
<div ng-repeat="subj in Subjects">
<input type="checkbox" ng-model="subjectModel[subj.SubjectId]"
ng-checked="SubjectIds.indexOf(subj.SubjectId)!=-1"/>
{{subj.SubjectName}}
</div>
</div>
You can use this code instead:
<div ng-repeat="subj in Subjects">
<input type="checkbox" ng-model="subjectModel[subj.SubjectId]" ng-checked="SubjectIds.indexOf(subj.SubjectId) != -1"/>{{subj.SubjectName}}
</div>

I have list of product and from each product use will add some quantity which I need in my controller.
the product list is not fix it might be 10 product (10 input box for qty) or may 100 product.
In HTML this is my code
<div class="col m3" ng-repeat="product in productlist" ng-cloak>
<h6 style="font-size:14px;">{{ product.product_name }}</h6>
<input ng-modal="qty[product.pid]" placeholder="Qty" type="number">
<button class="btn-flat" ng-click="addQty(product.pid)">ADD</button>
</div>
I am not understanding how I can get this value along with pid in controller
// ORDER ADD
$scope.addQty = function (pid) {
//$scope.qty = {};
//$scope.product = $scope.productlist;
console.log($scope.qty[pid]);
var getlistURL = $scope.baseURL+$scope.uri.uri_1+"/"+$scope.uri.uri_2+"/ng_add_to_cart/"+pid+"/";
$http.post(getlistURL).
success(function(data, status) {
if(data.length != 0) {
$scope.stockmovement = data;
$('#showStockMovement').modal('open');
}
});
};
Thanks
Here you should not try to pass just id like you did in the code. Instead of that, pass the entire object to the function and when you will manipulate its attributes, it will get effect on the page at the same time. This is how you can get real time effect of quantity change.
So modify the argument of the addQty function.
<div class="col m3" ng-repeat="product in productlist" ng-cloak>
<h6 style="font-size:14px;">{{ product.product_name }}</h6>
<input ng-modal="qty[product.pid]" placeholder="Qty" type="number">
<button class="btn-flat" ng-click="addQty(product)">ADD</button>
</div>
Then you can access any attribute of the product object in the function. Like written below:
// ORDER ADD
$scope.addQty = function (product) {
//$scope.qty = {};
//$scope.product = $scope.productlist;
console.log(product.pid);
var getlistURL = $scope.baseURL+$scope.uri.uri_1+"/"+$scope.uri.uri_2+"/ng_add_to_cart/"+product.pid+"/";
$http.post(getlistURL).
success(function(data, status) {
if(data.length != 0) {
$scope.stockmovement = data;
$('#showStockMovement').modal('open');
}
});
};
This is your solution.
Deducing from the limited information that is available, my guess is that you haven't initialized your array qty.
You should initialize your qty array to a length equal to the length of your productlist, with all initial values set to 0.
$scope.qty = [];
var initQty = function(){
for(var i = 0;i<$scope.productlist.length;i++){
$scope.qty[i]=0;
}
}();
Apart from that, your code looks fine after changing the ng-modal to ng-model, as already suggested by other folks.
I have updated my answer
angular.module('myApp', [])
.controller('myController', function($scope) {
//$scope.productlist = [];
$scope.modelData = {};
$scope.productlist = {
0:{"pid" : 1,
"product_name" : "Laptop",
},
1:{"pid" : 2,
"product_name" : "Computer",
},
2:{"pid" : 3,
"product_name" : "Camera",
},
3:{"pid" : 4,
"product_name" : "Tv",
}
}
$scope.addQty = function(pid){
alert(pid)
console.log($scope.modelData[pid])
}
});

Please check this demo. Let me know if it works!
if your productlist is of this type.
$scope.productlist =
[
{product_name: "Soap", pid: 25},
{product_name: "Bag", pid: 100}
];
Use this code
<div class="col m3" ng-repeat="product in productlist">
{{ product.product_name }}
<input ng-model="product.pid" placeholder="Qty" type="number">
<button class="btn-flat" ng-click="addQty(product)">ADD</button>
</div>
if you want to enter pid manually and get value in controller and don't want to attach with productlist
<div class="col m3" ng-repeat="product in productlist">
{{ product.product_name }}
<input ng-model="qty" placeholder="Qty" type="number">
<button class="btn-flat" ng-click="addQty(qty)">ADD</button>
</div>
and in your code type error is there change "ng-modal" to "ng-model"
seems like you want only the qty number so better try second one
https://plnkr.co/edit/gBLx1iIWL4x84ldtQAtF?p=preview
Here is a working plunker.. Changes I made are only 2 ng-model instead of ng-modal and initialised qty as object so now your quantities will be stored with pid as key of the object and qty as value of the object
for example :-
{ "1" : 6, "2" :12}
so you can basically have as many products you want with this
ng-repeat is an isolated scope , so model variables created in ng-repeat are not accessible in controller.
To solve your requirement we can follow two approaches
1.you can pass product id and quantity as two arguments and retrieve that in a function
<body ng-app="myApp" ng-controller="myCtrl">
<div class="col m3" ng-repeat="product in productlist" ng-cloak>
<h6 style="font-size:14px;">{{ product.product_name }}</h6>
<input ng-model="qty" placeholder="Qty" type="number">
<button class="btn-flat" ng-click="addQty(product.id,qty)">ADD</button>
</div>`
but this approach we dont have track of all products and all quantities, please check below plunker
https://plnkr.co/edit/zAz6FVgazOH4NWYpKb4u?p=preview
2.Second approch is following ControllerAs concepts , instead of using $scope we use ControllerAs to get values inside controller model.
<body ng-app="myApp" ng-controller="myCtrl as ctl">
<div class="col m3" ng-repeat="product in ctl.productlist" ng-cloak>
<h6 style="font-size:14px;">{{ product.product_name }}</h6>
<input ng-model="ctl.qty[product.id]" placeholder="Qty" type="number">
<button class="btn-flat" ng-click="ctl.addQty(product.id)">ADD</button>
</div>
{{ctl.qty}}
In this approach we can build an object called qty where we can keep track of all products and quantities
Please check below plunker for this approach

Hope this meets your requirement
I am trying to add a dropdown list with "Others" option. If user select "Others", Others (Please specify) input box will become Mandatory. How should I validate this case? Right now I added Javascirpt code to valid this. Is there anyway to do this like "Please specify other reason."?
<form name="myForm">
<div ng-app="myApp" ng-controller="myCtrl">
Reason : <select ng-model="reason" ng-options="x for x in names" required></select> <span ng-show="myForm.reason.untouched">The reason is required.</span>
<p>Others (specify): <input type="text" ng-model="others"></p>
</div>
</form>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.names = ["reason1", "reason2", "reason3","Others"];
$scope.addItem = function () {
if ($scope.reason == "Others" && !$scope.others)
{
window.alert("Please specify others");
}
if($scope.others && $scope.reason!='Others')
{
window.alert("Please select reason others");
}
});
</script>
Angular has an ng-required property that allows you to set it conditionally.
<form name="myForm">
<div ng-app="myApp" ng-controller="myCtrl">
Reason : <select ng-model="reason" ng-options="x for x in names" required>
</select> <span ng-show="myForm.reason.untouched">The reason is required.
</span>
<p>Others (specify): <input type="text" ng-model="others" ng-required="reason == 'Others'"></p>
</div>
</form>
I've built a shopping cart for a training site. People can purchase a number of 'seats' for each training session. What I need to add is a form requiring the name and email for each seat(attendee). So if someone purchases 3 seats, then I will need to generate form fields for each attendee.
I'm assuming there's something in the following code that plays a part in solving this problem but I'm not skilled enough in Angular to work it out.
ng-repeat="i in quantity track by $index"
look at this codepen
it works fine :)
var app = angular.module('myapp',[]);
app.controller('ctrlParent',function($scope){
$scope.myNumber=1;
$scope.range = function(count){
var output = [];
for (var i = 0; i < count; i++) {
output.push(i)
};
return output;
}
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myapp">
<div ng-controller="ctrlParent">
<input ng-model="myNumber" type="text" placeholder="Quantity"/>
<form ng-repeat="i in range(myNumber) track by $index">
<input type="text" placeholder="Name"/>
<input type="text" placeholder="Name"/>
<input type="text" placeholder="Name"/>
<input type="button" value="Ok"/>
</form>
</div>
</div>
First, get the number of seats, in the form (send the seats number by events OR shared service if the form are in another angular controller) So, let say $scope.nbrSeats (initial value = 0) in forms controller.
Second, using ng-repeat :
<form ng-repeat="i in nbrSeats">...</form>
Here is a working example for you:
var myApp = angular.module('myApp', []);
myApp.controller('MyCtrl', function($scope) {
$scope.quantity = '1';
$scope.availableQuantity = '10';
$scope.range = function(num) {
num = parseInt(num);
return new Array(num);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="MyCtrl">
<form name="myForm">
<select ng-model="quantity">
<option ng-repeat="option in range(availableQuantity) track by $index">{{$index + 1}}</option>
</select><br/><br/>
<div ng-repeat="customer in range(quantity) track by $index">
Customer {{$index + 1}} name: <input type="text" ng-model="customer_$index"><br/>
</div><br/><br/>
<button type="submit">Purchase</button>
</form>

$scope.fruits = ['apple', 'banana', 'cherry', 'orange', 'watermelon'];
$scope.selectedBasket = null;
};
});

</html>
if I select Mary or Jane, I can correctly see the correct items in their basket checked. However if I manually check all the fruits and then look at Mary or Jane, it doesn't exclude the items that are not in their baskets. Why is ng-checked failing?
Bonus question, is it best practise to set selectedBasket to null and checking for null in a directive assuming I want nothing as a default value, is there a better way?
You've got no ng-model in your checkbox so your manual action isn't registered anywhere.
ng-checked is only used to make a 'slave' checkbox it can take no manual action.
My guess is you should use a ng-model initialized to your ng-check value instead of using a ng-checked.
If you want to keep your ng-checked what you can do is :
<input type="checkbox" ng-click="selectedBasket.items.push(f)" ng-checked="selectedBasket !== null && selectedBasket.items.indexOf(f) !== -1">
in fact it's still wrong... must be tired, use a toogle function in your ng-click which add or remove the item should be better...
Had the same problem with ng-check, tried everything but nothing worked. I wanted to control the number of checked Items when clicked to 2, so I used the $Event sent with ng-click and disable it.
Here is a sample code:
<input type="checkbox" ng-click="toggleCheck($event, product._id);"
ng-checked="isChecked(product._id)">
$scope.toggleCheck($event, productId){
if ( $scope.featuredProducts.indexOf(productId) === -1) {
if ($scope.featuredProducts.length < 2) {
$scope.featuredProducts.push(productId);
}else {
$event.preventDefault();
$event.stopPropagation();
}
} else {
$scope.featuredProducts.splice( $scope.featuredProducts.indexOf(productId), 1);
}
}
$scope.isChecked(productId){
return ($scope.featuredProducts.indexOf(productId) !== -1);
}
Here's the jsFiddle: http://jsfiddle.net/VSph2/274/
I'm trying to make a filter with checkboxes.
When the user clicks the checkbox, it adds the id to an array called color_ids. I know that's working because I print the array in the console.
However, when I try to combine that with a filter, it doesn't work. I try to pass the $scope.color_ids array, but it is always passing an empty array and not passing the array with values in them.
app.controller('IndexCtrl', ['$scope', "Product", "Color", function($scope, Product, Color) {
...
// this method is triggered by a checkbox
$scope.toggleColorFilter = function(color_id) {
var index = $scope.color_ids.indexOf(color_id);
if (index > -1) {
$scope.color_ids.splice(index, 1);
} else {
$scope.color_ids.push(color_id);
}
console.log($scope.color_ids); //<-- prints the array properly with the new values.
};
}]);
and a filter that isn't working:
app.filter('productFilter', function(){
return function(input, color_ids) {
console.log(color_ids); //<-- prints an empty array all the time [ ]
return input;
}
})
This is my HTML
<h2>Products</h2>
<div class="filters col-two" ng-controller="IndexCtrl">
<h3>Color</h3>
<div ng-repeat="color in colors">
{{color.name}} <input type="checkbox" ng-model="color_ids" ng-change="toggleColorFilter(color.id)">
</div>
<h3>Shape</h3>
<h3>Material</h3>
</div>
<div class="products col-ten" ng-controller="IndexCtrl">
<div class="product" ng-repeat="product in products | productFilter:color_ids">
<h3>
{{ product.name }}
</h3>
<div class="product-thumbs">
<div class="image-wrapper" ng-repeat="product_color in product.products_colors">
<img src="{{ product_color.color.image.url }}" width="75" height="40">
</div>
</div>
</div>
</div>
I want the filter to eventually only show products with a color_id that exist in the color_ids array.
You have three divs with ng-controller="IndexCtrl" in your JSFiddle example. This is the problem. Each time the Angular compiler finds ng-controller in the HTML, a new scope is created.
<div class="filters col-two" ng-controller="IndexCtrl">
<h3>Color</h3>
<div ng-repeat="color in colors">{{color.name}}
<input type="checkbox" ng-model="color_ids" ng-change="toggleColorFilter(color.id)">
</div>
</div>
<div class="products col-ten" ng-controller="IndexCtrl">
<div class="product" ng-repeat="product in products | productFilter:color_ids">
{{ product.name }}
</div>
</div>
Simpliest way is to place this code in one controller and it will print 2 similiar arrays in your console:
<div ng-controller="IndexCtrl">
<div class="filters col-two">
<h3>Color</h3>
<div ng-repeat="color in colors">{{color.name}}
<input type="checkbox" ng-model="color_ids" ng-change="toggleColorFilter(color.id)">
</div>
</div>
<div class="products col-ten">
<div class="product" ng-repeat="product in products | productFilter:color_ids">
{{ product.name }}
</div>
</div>
</div>
JSFiddle
The filter is applied before the color_ids is updated, you should apply the filter in the controller inside the toggle function:
$filter('productFilter')($scope.products, $scope.color_ids);
Here is the working findle (at least I think): http://jsfiddle.net/VSph2/276/
Don't forget to inject the $filter in your controller.
