<label>Team Size</label>
<input type="text" class="s-txtboxes">
</span>
your ans will be very helpfull .
Thanks
updated jsFiddle
Angular has an already defined behavior for handling radio inputs. You don't have to use any radioChecked function, just use combination of ng-model and value on your inputs :
<input type="radio"
ng-model="hasTeam"
value="true"/> - Yes
<input type="radio"
ng-model="hasTeam"
value="false"/> - No
<span ng-if="hasTeam">
I'm showing only if yes is selected.
</span>
Maybe you should read the docs here.
you must use ng-hide or ng-show directive
for example
HTML
<input type="radio" id="radios3" name="radiosgg" class="SwitchOn" value="true" checked
ng-click="radioChecked()" ng-model="myvar" ng-hide="hideVar">
JavaScript
$Scope.hideVar = false;
$Scope.myvar = false;
$Scope.radioChecked= function () {
$Scope.hideVar = true; // Hide your checkbox
... dosomething...
}

I am working on an AngularJS application. I am trying to create a page that allows the user to select one of three radio buttons. Two of the three also have checkboxes underneath them to allow the user to select additional options if they've selected the appropriate radio button. To try to prevent improper checkbox selections, I'm trying to set the ng-disabled attribute on the checkboxes. So far, it's not working, and I've tried several different iterations.
This is my HTML:
<div class="panel-body">
<input type="radio" id="notFraudulent" name="actionSelector" ng-model="cleared" /><label for="notFraudulentRadio"> Not Fraudulent</label><br />
<input type="checkbox" id="highVolumeCustomer" ng-model="highVolumeCustomer" ng-disabled="(fraudulent||cleared)" /><label for="highVolumeCustomer"> High Volume Customer</label><br />
<br/>
<input type="radio" id="appearsFraudulent" name="actionSelector" ng-model="fraudulent" /><label for="isFraudulentRadio"> Appears Fraudulent</label><br />
<input type="checkbox" id="reportAccount" ng-model="reportAccount" ng-disabled="(cleared||reviewed)" /><label for="reportAccount"> Report Account</label><br />
<br/>
<input type="radio" id="markReviewed" name="actionSelector" ng-model="reviewed" /><label for="markReviewed"> Mark As Reviewed For Later</label>
</div>
I have tried changing the operator on the ng-disabled expressions to &&, as I've seen some articles where it's suggested that the operators don't mean what one thinks they mean. But that doesn't work, and neither does it work if I put just a single condition in the expression. There isn't anything in the controller (yet) that tries to use or manipulate any of the ng-models in the HTML. I've come to the conclusion that there's something I'm missing with regard to the radio buttons, but I can't for the life of me figure out what.
Can anyone see what my mistake is?
you should use value property to bind special value for radio button, and when radiobutton's status is changed, the value will be kept at ng-model.
refer the code snippet below:
angular.module("app", [])
.controller("myCtrl", function($scope) {
$scope.selectedValue = 'cleared';
$scope.cleared = false;
$scope.fraudulent = false;
$scope.reviewed = false;
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div class="panel-body" ng-app='app' ng-controller="myCtrl">
<input type="radio" id="notFraudulentRadio" name="actionSelector" value="cleared" ng-model="selectedValue" /><label for="notFraudulentRadio"> Not Fraudulent</label><br />
<input type="checkbox" id="highVolumeCustomer" ng-model="highVolumeCustomer" ng-disabled="selectedValue === 'fraudulent' || selectedValue === 'cleared'" /><label for="highVolumeCustomer"> High Volume Customer</label><br />
<br/>
<input type="radio" id="isFraudulentRadio" name="actionSelector" value="fraudulent" ng-model="selectedValue"/><label for="isFraudulentRadio"> Appears Fraudulent</label><br />
<input type="checkbox" id="reportAccount" ng-model="reportAccount" ng-disabled="selectedValue === 'cleared' || selectedValue === 'reviewed'" /><label for="reportAccount"> Report Account</label><br />
<br/>
<input type="radio" id="markReviewed" name="actionSelector" value="reviewed" ng-model="selectedValue"/><label for="markReviewed"> Mark As Reviewed For Later</label>
<br>
cleared:{{cleared}}<br>
fraudulent:{{fraudulent}}<br>
reviewed:{{reviewed}}<br>
selectedValue: {{selectedValue}}
</div>
Hi Friends I have radiobuttons
"%" and "Count"
If i click "%" then In the text box "%" Should be placeholder
If i click "Count" Then "Count" Should be placeholder for same textbox
Here Fiddle link:http://jsfiddle.net/qbauuzj2/
Html
<div class="winner-par">
<p>Winner Parameter</p>
<div class="onoffswitch-green2">
<input type="radio" id="radios5" name="radiosg5" class="SwitchOn" value="true" checked
ng-click="radioChecked()">
<label for="radios5">%</label>
<input type="radio" id="radios6" name="radiosg5" class="SwitchOff" value="false" ng-click="radiounChecked()">
<label for="radios6">Count</label>
</div>
</div>
<input type="text">
You can dynamically update DOM-elements
<div ng-app="" ng-controller="Controller">
...
<input type="text" placeholder="{{placeholder}}" />
</div>
Your controller
function Controller($scope) {
$scope.radioChecked = function ()
{
$scope.placeholder="%";
$scope.apply();
}
$scope.radiounChecked = function ()
{
$scope.placeholder="Count";
$scope.apply();
}
}

If you use >1.1.3 angular version - better way for this ng-attr-placeholder(thanks for Teq1)
<input type="text" ng-attr-placeholder="{{placeholder}}" />
Look at this
Follow this example:
Change value of input placeholder via model?
Depending on which is selected, change the value of the "placeholder" variable in your scope, then bind that variable to the placeholder attribute on the element.
In my HTML page, I have two sets of Boolean based radio buttons: Labeled: "Yes" and "No" / Values: True and False respectively. I'm populating a full form from a PostgreSQL database table to allow the authenticated user to view the form with populated data and edit the populated fields including the radio buttons, then save the form which will save the data to the DB. All of the other text fields populate without issue; it's both collection of radio buttons I am having an issue with pre-checkmarking the radio buttons.
The below does not pre-populate the checked on front end (but adds the correct attribute of checked in HTML source):
<input id="billing-no" type="radio" name="billing" ng-model="person.billing" value="FALSE" ng-checked="person.billing == 'false'" />
<input id="billing-yes" type="radio" name="billing" ng-model="person.billing" value="TRUE" ng-checked="person.billing == 'true'" />
However, this does check the correct radio button on load:
<input id="billing-no" type="radio" name="billing" value="FALSE" ng-checked="person.billing == 'false'" />
<input id="billing-yes" type="radio" name="billing" value="TRUE" ng-checked="person.billing == 'true'" />
Note: I needed to check against the string boolean value in the directive ng-checked since the boolean value always comes back as a string from PostgreSQL. This, apparently, was a part of PostgreSQL's design when querying data from columns that have boolean data types.
When adding the ng-model directive, the radio button no longer is checked (at least in the rendered browser view). The odd part is that I looked at the source and it clearly checks the correct one. What's even more odd, is that I have to click on the radio button twice to 'check' it. I've tested this in latest version of Chrome, FF, and IE and it all results in the same issue.
The question is: when adding the ng-model directive, why would the HTML source add 'checked' in the radio button attribute, but seemingly does not mark the radio button? Furthermore, why would I have to click twice on the radio button that IS supposed to be checked?
Solution:
To fix this, I removed the ng-checked directive from the radio buttons and only used ng-model as suggested by #Cypher and #aet. I then replaced the attribute value with the directive ng-value "true" & "false". After, I set the values in the controller.
HTML
<input id="billing-no" type="radio" name="billing" ng-model="person.billing" ng-value="false" />
<input id="billing-yes" type="radio" name="billing" ng-model="person.billing" ng-value="true" />
Angular JS
app.controller('peopleCtrl', function($scope, peopleFactory){
...
peopleFactory.getPerson(personParams).then(function(data){
$scope.person = data;
/* moved from ng-checked */
$scope.person.billing = data.billing == 'true';
});
...
};
I think you should only use ng-model and should work well for you, here is the link to the official documentation of angular https://docs.angularjs.org/api/ng/input/input%5Bradio%5D
The code from the example should not be difficult to adapt to your specific situation:
<script>
function Ctrl($scope) {
$scope.color = 'blue';
$scope.specialValue = {
"id": "12345",
"value": "green"
};
}
</script>
<form name="myForm" ng-controller="Ctrl">
<input type="radio" ng-model="color" value="red"> Red <br/>
<input type="radio" ng-model="color" ng-value="specialValue"> Green <br/>
<input type="radio" ng-model="color" value="blue"> Blue <br/>
<tt>color = {{color | json}}</tt><br/>
</form>
I solved my problem simply using ng-init for default selection instead of ng-checked
<div ng-init="person.billing=FALSE"></div>
<input id="billing-no" type="radio" name="billing" ng-model="person.billing" ng-value="FALSE" />
<input id="billing-yes" type="radio" name="billing" ng-model="person.billing" ng-value="TRUE" />

Avoiding using $scope, based on John Papa Angular Style Guide
so my idea is take advantage of the current model:
(function(){
'use strict';
var app = angular.module('way', [])
app.controller('Decision', Decision);
Decision.$inject = [];
function Decision(){
var vm = this;
vm.checkItOut = _register;
function _register(newOption){
console.log('should I stay or should I go');
console.log(newOption);
}
}
})();
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div ng-app="way">
<div ng-controller="Decision as vm">
<form name="myCheckboxTest" ng-submit="vm.checkItOut(decision)">
<label class="radio-inline">
<input type="radio" name="option" ng-model="decision.myWay"
ng-value="false" ng-checked="!decision.myWay"> Should I stay?
</label>
<label class="radio-inline">
<input type="radio" name="option" ng-value="true"
ng-model="decision.myWay" > Should I go?
</label>
</form>
</div>
</div>
I hope I could help ;)
Please explain why same ng-model is used? And what value is passed through ng- model and how it is passed? To be more specific, if I use console.log(color) what would be the output?
can we change URL when radio button selected. I am using angularjs?
following is my code and I want to change url when input radiobox is selected
<div class="switch">
<input type="radio" class="switch-input" name="view" value="week" id="week" checked>
<label for="week" class="switch-label switch-label-off">
Automatically
</label>
<input type="radio" class="switch-input" name="view" value="month" id="month">
<label for="month" class="switch-label switch-label-on">
Manually
</label>
<span class="switch-selection">
</span>
</div>
In AngularJS, you can use the $location service to change path as:
$location.path('/new-route');
On your input tag, you can then use the ng-change or the ng-click directives to call a function that will change the route. So, it can be something like this:
<input type="radio" ng-click="changeLocation('route-name')>
With your controller having the following code:
$scope.changeLocation = function (newRoute) {
$location.path(newRoute);
};
In AngularJS, I'm trying to add/remove a checked class on a parent element, when its child radio button is checked/unchecked.
<label ng-class="{checked: menuType.isChecked0}">
<input type="radio" name="menuType" ng-model="menuType.isChecked0" />Text 1
</label>
<label ng-class="{checked: menuType.isChecked1}">
<input type="radio" name="menuType" ng-model="menuType.isChecked1" />Text 2
</label>
Here is a fiddle: http://jsfiddle.net/fAA2w/
There is no controller or any other relative code. If there is a better way to approach this, please share. This seems simple enough, but I cannot find an answer to this question. What am I doing wrong here?
You need to give the radio input a value.
For more examples see http://docs.angularjs.org/api/ng/input/input%5Bradio%5D.
<div ng-app>
<label ng-class="{checked: isChecked == 1}">
<input type="radio" name="menuType" ng-model="isChecked" value="1" />Text 1
</label>
<label ng-class="{checked: isChecked == 2}">
<input type="radio" name="menuType" ng-model="isChecked" value= "2" />Text
</label>
</div>
This is the correct way to be doing it. Reason being, when your ng-model changes, your ng-class will pick up on that and update the view, the Angular way!
