I have some list to display for user reputation census.
With sigle option radio button I use this code and work great when user answer and then when he return on the same question to check his previous answer.
<li ng-repeat="item in items">
<input name="myName" value="{{item.id}}" type="radio"
ng-selected="myModel==item.id" ng-model="myModel"/>{{item.text}}
</li>
But with multiple option I've to use check box and I don't know how write code to mantain checked previous answer. Now I use this code but it doesn't work:
<li ng-repeat="item in items">
<input name="myName" checklist-value="{{item.id}}" type="checkbox"
ng-checked="myModel==item.id" checklist-model="myModel"/>{{item.text}}
</li>
Any help, please?
UPDATE
Now i have a model array with multiple value inside (myModel). With following code i'm not able to check correct items.
<li ng-repeat="item in items">
<input name="myName" checklist-value="{{item.id}}" type="checkbox"
ng-checked="myModel[$index]==item.id" checklist-model="myModel"/>{{item.text}}
</li>
Where is my error?
Thanks
Try following snipet
<li ng-repeat="item in items">
<input name="myName" type="checkbox" ng-model="ngModel"
ng-checked="myModel===item.id" ng-true-value="{{item.id}}"/>{{item.text}}
</li>
<label ng-repeat="language in languages">
<input type="checkbox" data-checklist-model="profile.languageId" data-checklist-value="language.languageId">
{{language.Language}}
</label>
It is working
Step:
you need to download "checklist-model.js" file (link)
you need to inject "checklist-model" module in your app.
then your code will work.

I want to validate an angular form input and give it a class if is not $valid, the problem is, it´s inside a ng-repeat looping an array of int, and the input name is based on the $index:
<li ng-repeat="item in selectedItem.data.ax_ch">
<div ng-class="{'has-error':!form.ax_$index.$valid}">
<input type="text" id="ax_{{$index}}" name="ax_{{$index}}" ng-model="item" required=""/>
</div>
</li>
Everything gets the $index in the output, but the ng-class:
<li ng-repeat="item in selectedItem.data.ax_ch">
<div ng-class="{'has-error':!form.ax_$index.$valid}">
<input type="text" id="ax_0" name="ax_0" ng-model="item" required=""/>
</div>
</li>
What I expected it to be:
<li ng-repeat="item in selectedItem.data.ax_ch">
<div ng-class="{'has-error':!form.ax_0.$valid}">
<input type="text" id="ax_0" name="ax_0" ng-model="item" required=""/>
</div>
</li>
I have searched and people have similar problems but none of them have been solved so far. Is there any angular-super-hero-master-plus-advanced who can help me with it :) ?
Because you are constructing the property/key on form dynamically, you do the same thing you would in normal Javascript: use square["bracket"] notation.
Change your markup to:
<li ng-repeat="item in selectedItem.data.ax_ch">
<div ng-class="{'has-error':!form['ax_' + $index].$valid}">
<input type="text" id="ax_{{$index}}" name="ax_{{$index}}" ng-model="item" required=""/>
</div>
</li>
I'm trying to display two ng-repeats showing the same array in two different formats: A simple list with checkboxes and the same list, with extended info and checkboxes.
The following example works fine in Angular.
<label ng-repeat="item in vm.items">
<input type="checkbox" ng-model="item.selected">
{{item.name}}
</label>
<div ng-repeat="item in vm.items">
<h1>{{item.name}}</h1>
<p>{{item.desc}}</p>
<input type="checkbox" ng-model="item.selected">
</div>
But if I use Material Design Lite, the checked state isn't updated, so when you click in one checkbox, the other one stills the same.
Real example:
<div ng-repeat="item in vm.items">
<div class="mdl-card__title" ng-style="{'background-image': 'url({{item.photo}})'}">
<h2 class="mdl-card__title-text">{{item.name}}</h2>
</div>
<label class="mdl-checkbox mdl-js-checkbox mdl-js-ripple-effect" for="checkbox-{{$id}}">
<input type="checkbox" ng-model="item.selected" ng-change="vm.updateMDL()" class="mdl-checkbox__input" id="checkbox-{{$id}}">
<span class="mdl-checkbox__label">Select {{item.name}}</span>
</label>
</div>
And in the list:
<div ng-repeat="item in vm.items">
<label class="mdl-checkbox mdl-js-checkbox mdl-js-ripple-effect" for="checkbox-list-{{$id}}">
<input type="checkbox" ng-model="item.selected" class="mdl-checkbox__input" id="checkbox-list-{{$id}}">
<span class="mdl-checkbox__label">{{item.name}}</span>
</label>
</div>
If I click one checkbox then the same one in the list, object's selected status gets toggled and the clicked checkbox doesn't change (since it didn't change to selected in the first place)
Anyone else facing this issue? Workarounds?
I am trying to create a dynamic form with multiple radio button options and get selected values..
<form name="myForm" ng-submit="sendAnswers(question)">
<ul>
<li ng-repeat="question in questionForm.questions">
<p>{{question.description}}</p>
<ul>
<li ng-repeat="option in question.options">
<input type="radio" ng-model="question.answer" value="option.value">
{{option.value}}
</li>
</ul>
</li>
</ul>
<p><input type="submit" value="sendAnswers"></p>
</form>
Problem is as I click on button, both options get selected..what am I doing wrong here?
Live example: http://plnkr.co/edit/aStk4SCHzAW0AKQuH7JE?p=preview
Thanks in advance!
Add a "name" parameter:
<input name="{{question.description}}" type="radio" ng-model="question.answer" value="option.value">
Also, you need to change "value" to {{option.value}}
<input name="{{question.description}}" type="radio" ng-model="question.answer" value="{{option.value}}">
Working Example
Angular ng-repeat with filter works this way (I just discovered it by observing DOM in Chrome's developer tools):
It actually removes the nodes which don't satisfy filter condition and re-renders everything.
See this fiddle example. If you look at the DOM, and see what happens there, you can understand what I mean.
<div ng-app>
<h2>Instant Search</h2>
<div ng-controller="SearchCtrl">
<input type="text" ng-model="filterText" />
<ul>
<li ng-repeat="state in states | filter:filterText">
<label>
<input type="checkbox" ng-model="state.abbreviation">
{{state.name}}
</label>
</li>
</ul>
</div>
</div>
What I need now, is to make angular js hide nodes, not remove them. In other words, when I filter nodes, for example I want to make those nodes which don't satisfy filter condition to have a class of hidden, and I'll hide them via CSS.
ng-show placed on the repeating element will cause them to be hidden: Fiddle http://jsfiddle.net/NAumK/19/
http://docs.angularjs.org/api/ng.directive:ngShow
<div ng-app>
<h2>Todo</h2>
<div ng-controller="TodoCtrl">
<input type="text" ng-model="filterText" />
<ul>
<li ng-repeat="state in states" ng-show="state.name.indexOf(filterText) != -1">
<label>
<input type="checkbox" ng-model="state.abbreviation">
{{state.name}}
</label>
</li>
</ul>
<input type="text" ng-model="textFilter" />
</div>
</div>
Filters remove elements as does the ng-if and ng-switch directives. You can also use css coupled with the ng-class directive to hide the elements however I recommend sticking with the ng-show for clarity. One further note of caution, hiding as opposed to removing elements makes the test cases harder to prove. You can have collisions with classes that display incorrectly but still pass (Selenium) tests.
You can use ng-show or ng-hide instead of filters.
You cannot use filter in ng-repeat because it filters the actual array that ng-repeat receives. You'll have to implement your own "filtering" logic.
I'd do it using a conditional ng-class, like this:
<li ng-repeat="state in states" ng-class="{'hidden': isHidden(state)}">
<label>
<input type="checkbox" ng-model="state.abbreviation">
{{state.name}}
</label>
</li>
$scope.isHidden = function(state) {
if(state.name.toLowerCase().indexOf($scope.filterText.toLowerCase()) < 0) {
return true;
}
return false;
}
I thinks that one answer would be like this
<div ng-app>
<h2>Instance Search</h2>
<div ng-controller="SearchCtrl">
<input type="text" ng-model="filterText" />
<ul>
<li ng-repeat="state in states"
ng-show="state.name.tolowerCase().indexOf(filterText.toLowerCase()) != -1">
<label>
<input type="checkbox" ng-model="state.selected">
{{state.name}}
</label>
</li>
</ul>
</div>
</div>
Just replace filter with:
ng-show="([state] | filter:filterText).length > 0"
ng-repeat's each item get its own scope, but how to get the input value?
In a normal situation, just set a ng-model and refer it through $scope.
<div ng-repeat="item in items">
<input type="text">
</div>
Is thre a way to work around this?
<div ng-repeat="item in items">
<input type="text" ng-model="item.value">
</div>
