I am trying create multiple checkboxes using ng-repeat from Array1, and I'd like apply the "checked" attribute (using ng-checked) to certain ones depending if there is a match in Array2.
Here we have array1 in the controller:
$scope.possibleConditions = ["condition1", "condition2", "condition3", "condition4"];
and then array2 is from the same controller but via JSON API.
{
"treated" : false,
"data" : [{
"conditions" : ["condition1", "condition2"],
}]
}
This is my current ng-repeat set up in the template:
<p ng-repeat="condition in possibleConditions">
<input type="checkbox" id="{{condition}}" />
<label for="{{condition}}">
{{condition}}
</label>
</p>
The desire is to apply the attribute checked to the input if, say, "condition1" in Array1 is found in "conditions" from Array2.
What I've tried:
1: I've tried using a filter (which I found on stackoverflow) after my controller:
.filter('customArray', function($filter){
return function(list, arrayFilter, element){
if(arrayFilter){
return $filter("filter")(list, function(listItem){
return arrayFilter.indexOf(listItem[element]) != -1;
});
}
};
with the ng-repeat amended slightly:
<p ng-repeat="conditions in possibleConditions | customArray:profileData.data:'conditions' ">
But that didn't work.
2: I've tried using another ng-repeat within the ng-repeat, then check it against the first one fir a match.
Example:
<p ng-repeat="conditions in possibleConditions">
<input ng-repeat="condition in profileData.data[0].conditions | filter{condition == conditions}" type="checkbox" id="{{condition}}" />
<label ng-repeat="condition in profileData.data[0].conditions | filter{condition == conditions}" for="{{condition}}">
{{condition}}
</label>
</p>
Hopefully somebody can help / point some guidance.
Thank You.
You don't really need a filter here, simple ngChecked directive could work:
<p ng-repeat="condition in possibleConditions">
<input type="checkbox" id="{{condition}}"
ng-checked="response.data[0].conditions.indexOf(condition) > -1" />
<label for="{{condition}}">
{{condition}}
</label>
</p>

where response is your data from API.

I am creating a html / angularjs form. In the form i have a radio button with yes or no. So i want to check by default the button No.
This is the code i use :
My controller :
angular.module('radioExample', [])
.controller('ExampleController', ['$scope', function($scope) {
$scope.myvariable = 'false';
}]);
My html code snippet:
<div class="col-lg-10">
<input type="radio" id="variable" name="variable" ng-model="myvariable" value="true">Yes</input>
<input type="radio" id="variable" name="variable" ng-model="myvariable" value="false">No</input>
</div>
But nothing is selected(checked) when i load the form the first time. I have to click to one value to have one selected (checked)
What's wrong with my code ? Here the plunker link
Thanks
I've made a fiddle for you. Check HERE
You should also set ng-value which should be true or false
<div ng-controller="MyCtrl">
<div ng-repeat="o in options">
<input type="radio" name="group1" ng-model="o.checked" ng-value="o.checked"></input>
<label>{{o.name}}</label>
</div>
</div>
var myApp = angular.module('myApp', []);
function MyCtrl($scope) {
$scope.options = [
{ name: 'OPT1', id: 1, checked: false },
{ name: 'OPT2',id: 2, checked: false },
{ name: 'OPT3',id: 3, checked: true }
];
}
The reason why it does not work in your plunkr is because you create a module named "radioExample" but you don't use it when you write the HTML code.
Basically, replace this -
<html ng-app>
at the beginning of the code with this
<html ng-app="radioExample">
This way, when you declare the controller, AngularJS knows which module it needs to look into to get the controller.
Note - if you had not associated your controller with a module, then your code would work.
Check out ng-checked. What you have to do is to add ng-app="radioExample" to the html-Tag of your Application.
Then add ng-checked="myvariable == 'false'" and ng-value="'value'" like in the following plunker example:
Plunker
<div class="col-lg-10">
<input ng-checked="myvariable == 'true'" type="radio" id="variable" name="variable" ng-model="myvariable" value="true">Yes
<input ng-checked="myvariable == 'false'" type="radio" id="variable" name="variable" ng-model="myvariable" value="false">No
</div>
Error in data binding. Define myvariable in controller override value in radiobutton. You must use ng-repeat like
<div ng-repeat="o in options">
<input type="radio" name="name" ng-model="o.checked" ng-value="o.checked"></input>
<label>{{o.name}}</label>
</div>
(I use code from previous answer)
I have a checkbox that should check all checkboxes. The checkbox works as it should by checking all the checkbox's, however angular doesnt think they have been checked? The only way angular knows if they are checked is if i manually check each one. (The brackets and for loop are blade php from laravel)
<label class="checkbox-inline">
<input type="checkbox" ng-model="everyoneCheck"/> Everyone
</label>
#foreach($company->users as $tagIndex => $user)
<label class="checkbox-inline">
<input type="checkbox" ng-checked="everyoneCheck" ng-model="newDiscussion.notify_partners[{{$tagIndex}}]" ng-true-value="{{$user->id}}" /> {{ $user->first_name }} {{ $user->last_name }}
</label>
#endforeach
upon click of the submit button i proceed to $http.post to my server, i just pass in an object to the post function, this is the object.
var discussionData = {
'title': $scope.newDiscussion.title,
'discussion': $scope.newDiscussion.summary,
'company_id': company_id,
'notify_partners': $scope.newDiscussion.notify_partners
};
for some reason when i use the check all approach, nothing gets put into notify_partners, however when i manually click each checkbox, they will get entered and submitted properly.
Any help? I feel like its some sort of binding issue, where i just need to tell angular, hey its updated!
Here's a way to do it:
<p><input type="checkbox" ng-model="globalCheck" ng-click="toggleCheckAll()" /> Check All</p>
<ul>
<li ng-repeat="i in init">
<input type="checkbox" ng-model="checkbox[$index]" /> Checkbox {{ $index + 1 }} {{ checkbox[$index] }}
</li>
</ul>
Then in your controller:
function myControl($scope) {
$scope.globalCheck = false;
$scope.checkbox = {};
$scope.init = [0,1,2,3,4,5,6,7,8,9];
$scope.toggleCheckAll = function() {
var k, val = !$scope.globalCheck;
console.log(val);
for(k in $scope.init) {
$scope.checkbox[k] = val;
}
}
}
See JSfiddle for working example
ng-checked does not update the value bound in ng-model. It only affects the presence of the checked attribute on the element itself.
Your best bet is to use ng-change to execute some function and update all your models accordingly.
<input type="checkbox"
ng-model="everyoneCheck"
ng-change="toggleCheckAll()"/>
And in your controller, you can have toggleCheckAll() loop over your models and set them based on the value of everyoneCheck
I'm new to Angular so this might be real easy.
I have a JSON array of some offers. Each offer has a price among other things. I want to be able to add a filter so that the user can specify their min/max spent and only sees offers that fall into these brackets.
In the list controller I have
// MinMax filter:
$scope.minMax = function(prop, mn, mx){
return function(item){
if ( (Number(item[prop]) >= mn) && (Number(item[prop])<= mx) ) return true;
}
}
In the View HTML I have two simple text input fields:
<input id='cheapest' name="cheapest" type='text' value='10' />
<input id='dearest' name="dearest" type='text' value='5000' />
and the repeater
<div ng-repeat="offer in offers | filter: minMax('Price' , [?cheapest?], [?dearest?]) ">
The filter works when I hardcode values in, but how do I bind them to the input field?
Thanks
This is a calling to Captain ngModel ;)
Just bind your input values:
<input id='cheapest' name="cheapest" type='text' value='10' ng-model="cheapest" />
<input id='dearest' name="dearest" type='text' value='5000' ng-model="dearest" />
and pass the value to your filter:
<div ng-repeat="offer in offers | filter: minMax('Price', cheapest, dearest) ">
or access them via $scope.cheapest in your controller.
I am not sure with the syntax though but it will work somehow :)
After reading this article, I understand how to dynamically add a form field using ng-repeat.
I am wondering how can multiple form elements be dynamically created with incrementing ng-model values.
For example, the following would be created from a button click.
<input ng-model="vm.foo.bar1.first">
<input ng-model="vm.foo.bar1.second">
<input ng-model="vm.foo.bar1.third">
<input ng-model="vm.foo.bar1.fourth">
<input ng-model="vm.foo.bar2.first">
<input ng-model="vm.foo.bar2.second">
<input ng-model="vm.foo.bar2.third">
<input ng-model="vm.foo.bar2.fourth">
<input ng-model="vm.foo.bar3.first">
<input ng-model="vm.foo.bar3.second">
<input ng-model="vm.foo.bar3.third">
<input ng-model="vm.foo.bar3.fourth">
How can this be done?
I would suggest to restructure your ViewModel to make vm.foo.bar an array. Then this would be trivial:
<div ng-repeat="item in barItems">
<input ng-model="vm.foo.bar[$index].first">
<input ng-model="vm.foo.bar[$index].second">
<input ng-model="vm.foo.bar[$index].third">
<input ng-model="vm.foo.bar[$index].fourth">
</div>
Or, if you insist, then also
<div ng-repeat="item in barItems" ng-init="outerIdx = $index">
<input ng-repeat='p in ["first", "second", "third", "fourth"]'
ng-model="vm.foo.bar[outerIdx][p]">
</div>
(I'm assuming here, that unlike with first, second, etc..., the number of bars is not known - hence an array is a better option)
EDIT:
If you really want, you could also make vm.foo an object that holds properties bar1, bar2, etc...:
<div ng-repeat="item in [1, 2, 3, 4]">
<input ng-model="vm.foo['bar' + item].first">
<input ng-model="vm.foo['bar' + item].second">
<input ng-model="vm.foo['bar' + item].third">
<input ng-model="vm.foo['bar' + item].fourth">
</div>
but don't forget to first create vm.foo object in the controller:
this.foo = {};
When I have to do this I use the $index to control the names of things. Although I've never tried this exact code, this should work.
<input ng-model='vm.foo.bar3[$index]'></input>
$index comes along whenever you do ng-repeat and is just the index of the list item. So that should end up making ng-models that are vm.foo.bar3.0 to whatever.
To my point of view, you should create arrays of models in your controller.
$scope.vm.foo = [{
bar1: [{
first: '',
second: '',
...
},
bar2: ...
],
}]
And then in your view iterate on your tab :
<div ng-repeat="elem in foo">
<div ng-repeat="input in elem">
<input ng-model="input">
</div>
</div>
Hope it will help you !
I have a javascript array like so:
$scope.quantityMachines = [
{ 'snippet' : 'One' },
{ 'snippet' : 'Two' },
{ 'snippet' : 'Three or more',
'extraField' : true },
{ 'snippet' : 'Not sure, need advice' }
];
Then I have a list of radio buttons generated by Angular JS using the array:
<ul>
<li ng-repeat="quantity in quantityMachines">
<input type="radio" id="quantityMachines{{$index}}" name="quantityMachines" value="{{quantity.snippet}}" ng-model="howMany" />
<label for="quantityMachines{{$index}}">{{quantity.snippet}}</label>
</li>
</ul>
This works. In the array there is an extraField with value true in one of the indexes. I need Angular to show an extra input field when a radio button with the extraField setting is checked. The array may change to have more than one index with the extraField value.
So the extra field would look something like this.
<input type="text" ng-model="extraInfo" ng-show="howMany" />
Other than knowing to use ng-show, I'm not sure what would be the correct way to do this. The above example of course does nothing.
You could use ng-if and ng-show combination and a scope variable to keep track what is selected. ng-if will make sure the textbox is not added unwantedly to the DOM and ng-show to show and hide as the radio gets toggled.
In your input:-
<input type="text" ng-model="extraInfo" ng-if="quantity.extraField" ng-show="option.selected === howMany" />
and in your Radio add ng-click="option.selected=quantity.snippet"
<ul>
<li ng-repeat="quantity in quantityMachines">
<input type="radio" id="quantityMachines{{$index}}" name="quantityMachines" value="{{quantity.snippet}}" ng-model="howMany" ng-click="option.selected=quantity.snippet"/>
<label for="quantityMachines{{$index}}">{{quantity.snippet}}</label>
<input type="text" ng-model="extraInfo" ng-if="quantity.extraField" ng-show="option.selected === howMany" />
</li>
</ul>
and add in your controller:-
$scope.option = { selected:'none'};
Bin
You could even use howMany to track what was selected except that you need to set it as a property to an object on the scope (Since ng-repeat creates its own child scope and proto inheritance comes to play).
So in your radio just add ng-model="option.howMany", in your controller add $scope.option = { }; and in the text box ng-if="quantity.extraField" ng-show="quantity.snippet === option.howMany"
Bin
If only you had a plunker...without that try this
<ul>
<li ng-repeat="quantity in quantityMachines">
<input type="radio" id="quantityMachines{{$index}}" name="quantityMachines"
value="{{quantity.snippet}}" ng-model="howMany" />
<label for="quantityMachines{{$index}}">{{quantity.snippet}}</label>
<input type="text" ng-model="extraInfo" **ng-if="quantity.extraField"** />
</li>
</ul>
http://jsbin.com/biwah/1/edit?html,js,output
<ul>
<li ng-repeat="quantity in quantityMachines">
<input type="radio" id="quantityMachines{{$index}}" name="quantityMachines" value="{{quantity.snippet}}" ng-model="howMany" />
<label for="quantityMachines{{$index}}">{{quantity.snippet}}</label>
<input type="text" ng-model="quantity.extraInfo" ng-show="quantity.extraField" />
</li>
</ul>
The easiest way to show something when radio button is checked is the following:
Lets say you have a radio-group with: ng-model="radio-values"
To show or hide your input then depends on the values within the radio-group: value="radio-value1", value="radio-value2"
To finally show or hide the input field (lets say you want to show something if "radio-value1" is set) you do:
<input ng-show="radio-values == 'radio-value1'" ...>
