how to use ng-show with checkboxes - javascript

I have tried all the solutions i could find but i am stuck. I have 2 checkboxes, HBO and Marvin. Marvin needs to show a div. HBO needs to show nothing. It works until I need to click the checkbox twice for it to show/hide. usually this would be a $apply() issue but that does not seem to be the case. I believe I am not updating the model correctly. I forgot to mention that the checkboxes need to reset to false when the other is true.
plunker
var ctrl = this;
ctrl.showMeMarvin = function () {
if (ctrl.show === true) {
//$timeout(function () {
ctrl.marvin = false;
ctrl.show = false;
ctrl.hbo = false;
//})
}
else {
//$timeout(function () {
ctrl.marvin = true;
ctrl.show = true;
ctrl.hbo = false;
//})
}
};
ctrl.showMeHBO = function () {
if (ctrl.show === true) {
// $timeout(function () {
ctrl.show = false;
ctrl.hbo = true;
ctrl.marvin = false;
//})
}
else {
//$timeout(function () {
ctrl.marvin = false;
ctrl.hbo = true;
//})
}
};

Just change the div ng-show like this:
<div class="col-xs-12" ng-show="checkedHBO == 1">
And it will work without any additional functions calls.
Edit:
To have it working with the condition to reset the prev selected value you can use this:
<div ng-controller="ShowController as ctrl">
<div class="col-xs-12">
<label for="checkedHBO" class="ts-label">HBO</label>
<input id="checkedHBO" name="mygroup" type="radio" value="hbo" ng-model="checkedHBO" ng-change="checkedMarvin = undefined"/>
<label for="checkedMarvin" class="ts-label">Marvin</label>
<input id="checkedMarvin" name="mygroup" type="radio" value="marvin" ng-model="checkedMarvin" ng-change="checkedHBO = undefined"/>
</div>
<div class="col-xs-12" ng-show="checkedHBO">
<center>
<div class="jumbotron">
DIV 1
</div>
<div class="jumbotron">
DIV 2
</div>
<div class="jumbotron">
DIV 3
</div>
</center>
</div>
</div>

You should be using a radio input instead of checkboxes. http://plnkr.co/edit/hE68w9RKUoFamAWGgRzR?p=preview
<input name="radio" id="checkedHBO" type="radio" ng-model="ctrl.show" ng-value="false" />
<input name="radio" id="checkedMarvin" type="radio" ng-model="ctrl.show" ng-value="true"/>

angular ng-disable checkbox not update with dynamic source

I have several checkboxes dynamicaly generated from array source:
/*js*/
$scope.arrondissements = JSON.parse('
[{"name":"4e","checked":false,"disable":true},
{"name":"5e","checked":false,"disable":false},
{"name":"11e","checked":false,"disable":false},
{"name":"12e","checked":false,"disable":false},
{"name":"13e","checked":false,"disable":false},
{"name":"14e","checked":false,"disable":false},
{"name":"15e","checked":false,"disable":false},
{"name":"16e","checked":false,"disable":false},
{"name":"17e","checked":false,"disable":false},
{"name":"18e","checked":false,"disable":false},
{"name":"19e","checked":false,"disable":false},
{"name":"20e","checked":false,"disable":false}]');
<!-- HTML -->
<div ng-repeat="item in arrondissements" class="checkbox-inline ">
<label>
<input type="checkbox" ng-disabled="{{item.disable == true}}"
value="{{item.checked}}" ng-model="item.checked" >
<span>{{item.name}}</span>
</label>
</div>
Checkboxes are generated correctly but When source gets updated , checkbox doesn't update
/*js*/
$scope.disableCb = function () {
$scope.arrondissements[5].disable = true;
$scope.arrondissements[6].disable = true;
$scope.arrondissements[7].disable = true;
}
<!-- HTML -->
<button ng-click="disableCb()">disable</button>
Could you tell me why and how to fix it?
I made a Plunker : http://plnkr.co/edit/jD1l3NgJuduTOoskpeVM
You should define your $scope.disableCb function inside your controller function.
function controller( $scope) {
var vm = $scope;
$scope.title = 'controller';
$scope.arrondissements = JSON.parse('[{"name":"4e","checked":true,"disable":true},{"name":"5e","checked":false,"disable":false},{"name":"11e","checked":false,"disable":false},{"name":"12e","checked":false,"disable":false},{"name":"13e","checked":false,"disable":false},{"name":"14e","checked":false,"disable":false},{"name":"15e","checked":false,"disable":false},{"name":"16e","checked":false,"disable":false},{"name":"17e","checked":false,"disable":false},{"name":"18e","checked":false,"disable":false},{"name":"19e","checked":false,"disable":false},{"name":"20e","checked":false,"disable":false}]');
$scope.disableCb = function () {
$scope.arrondissements[5].disable = true;
$scope.arrondissements[6].disable = true;
$scope.arrondissements[7].disable = true;
}
}
I've also fixed how you used your directives. I've removed the value attribute on the checkboxes since they're redundant with ng-model.
I've fixed your usage of ng-disabled as well
<div ng-repeat="item in arrondissements" class="checkbox-inline ">
<label>
<input type="checkbox" ng-disabled="item.disable"
ng-model="item.checked" >
<span>{{item.name}}</span>
</label>
</div>
<button ng-click="disableCb()">disable</button>

Adding event on ng-repeat element

I am very new to angular :). I would like to add a simple event one form element with a particular value, built by ng-repeat. This is how the HTML looks:
<div class="labels">
<div class="checkbox-element" ng-repeat="suggestName in $ctrl.suggests" ng-click="$ctrl.toggleSelection(suggestName, 'suggestsSelection', this)">
<label>
<input type="checkbox" name="suggestsSelection[]"
class="hidden"
value="{{suggestName}}"
><span></span>{{suggestName}}
</label>
</div>
<div class="optionary hidden">
<br>
<div class="question__text">Any other?</div>
<label><input type="text"
ng-model="$ctrl.survey.suggest_other"
name="suggests_other1"></label><br>
</div>
</div>
And the controller code:
vm.survey = {};
vm.suggests = ['quality', 'price', 'habbit', 'other'];
// selected
vm.survey.suggestsSelection = [];
// toggle selection for a given names
vm.toggleSelection = function toggleSelection(value, array, scope) {
var idx = vm.survey[array].indexOf(value);
// is currently selected
if (idx > -1) {
vm.survey[array].splice(idx, 1);
}
// is newly selected
else {
vm.survey[array].push(value);
}
};
What I need is to create an event that would toggle the class "hidden" from the div with class "optionary" after clicking on the last created checkbox ("other" in this case). Clicking on other checkboxes shouldn't affect the "optionary" div.
I tried with some configurations like:
if(scope.$last){
$(scope).closest('.optionary').toggleClass('hidden');
}
or similar. I don;t know what should be the way to approach the topic.
You need to use ng-show and a control variable. Take a look.
jsFiddle here: https://jsfiddle.net/U3pVM/24834/
<div ng-app class="labels" ng-controller="MyCtrl">
<div class="checkbox-element" ng-repeat="suggestName in suggests" ng-click="toggleSelection(suggestName, suggestsSelection, this)">
<label>
<input type="checkbox" ng-model="cbSuggest[$index]" name="suggestsSelection[]" class="hidden" value="{{suggestName}}">
<span>{{suggestName}}</span>
</label>
</div>
<div class="optionary hidden" ng-show="showOther">
<br>
<div class="question__text">Any other?</div>
<label><input type="text" ng-model="survey.suggest_other" name="suggests_other1"></label><br>
</div>
</div>
var myApp = angular.module('myApp',[]);
function MyCtrl($scope) {
$scope.survey = {};
$scope.suggests = ['quality', 'price', 'habbit', 'other'];
$scope.cbSuggest = [];
$scope.showOther = true;
// selected
$scope.survey.suggestsSelection = [];
// toggle selection for a given names
$scope.toggleSelection = function(value, array, scope) {
var showOther = true;
angular.forEach($scope.cbSuggest, function(k,v){
if(k) {
showOther = false;
}
});
$scope.showOther = showOther;
};
}
As you can see ng-repeat has special properties: https://docs.angularjs.org/api/ng/directive/ngRepeat
The one you're interested in is $last. You could add ng-change to your checkboxes, call a function with the paramter $last, and that function would set a scope variable. The hidden class could rely on that.
Something like this:
<input type="checkbox" name="suggestsSelection[]"
class="hidden"
ng-change="showHidden($last)"
value="{{suggestName}}">
And in your controller:
$scope.hidden = true;
$scope.showHidden = function(isLast) {
if (isLast) $scope.hidden = false;
else $scope.hidden = true;
}
And then you add ng-class to your div:
<div class="optionary" ng-class="{'hidden': hidden}">...</div>

Default Select all checkboxes in angularjs

I am creating a app in angularjs. I have problem while showing all checkbox selected when page open.
here is my code:
<div class="check_box">
<input type="checkbox" id="checkbox1" name="checkbox" ng-model="selectedAllStatus" ng-click="checkAllTypes()">
<label for="checkbox1"><span for="checkbox1">All</span></label>
</div>
</li>
<li ng-repeat="customersFlowsList in customersFlows | unique:'type'" ng-init="checkAllTypes()">
<div class="check_box">
<input type="checkbox" id="checkbox1" name="checkbox" ng-model="filter[customersFlowsList.type]">
<label for="checkbox1"><span for="checkbox1">{{customersFlowsList.type | customerType}}</span></label>
</div>
</li>
Here is my js code:
$scope.checkAllStatus = function()
{
console.log($scope.selectedAll)
if ($scope.selectedAll) {
$scope.selectedAll = true;
} else {
$scope.selectedAll = false;
}
angular.forEach($scope.customersFlows, function (customersFlowsList) {
$scope.filterLink[customersFlowsList.linkStatus] = $scope.selectedAll;
});
}
On click of button all checkboxes selected(this is working),but I want when page is open then all checkboxes should be selected.
you can do it in controller before template load
$scope.checkAllStatus = function() {
console.log($scope.selectedAll)
if ($scope.selectedAll) {
$scope.selectedAll = true;
} else {
$scope.selectedAll = false;
}
angular.forEach($scope.customersFlows, function(customersFlowsList) {
$scope.filterLink[customersFlowsList.linkStatus] = $scope.selectedAll;
});
}
$scope.selectedAllStatus = true;
$scope.checkAllStatus()

Error in enabling submit button when all field are entered

I have a login form.
Field: Username textbox, password text box, 2 check boxes, submit button--- everything inside a form.
submit button initially disabled. It is enabled only when username, password or AT LEAST any one checkbox is checked. button gets enabled when username & password fields are entered. no change happens even if checkbox is checked or unchecked.
<form class="form-horizontal" role="form" action="page2.html">
<div class="form-group">
<label for="txtusername" class="col-sm-4 control-label ">Username</label>
<div class="col-sm-8">
<input type="text" class="form-control textboxprop" id="txtusername" placeholder="Username">
</div>
</div>
<div class="form-group">
<label for="txtpassword" class="col-sm-4 control-label ">Password</label>
<div class="col-sm-8">
<input type="password" class="form-control textboxprop" id="txtpassword" placeholder="Password">
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-4 col-sm-8">
<div class="checkbox">
<input id="chk" type="checkbox" >chk1
<input id="chk" type="checkbox" >chk2
</div>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-4 col-sm-8">
<button type="submit" id="signin" class="btn btn-default" disabled>Sign in</button>
</div>
</div>
</form>
This is the form. Below given is the javascript function I use.
var $input = $('input'),
$register = $('#signin');
$register.attr('disabled', true);
$input.keyup(function() {
var trigger = false;
$input.each(function() {
if (!$(this).val()) {
trigger = true;
}
});
trigger ? $register.attr('disabled', true) : $register.removeAttr('disabled');
});
You need to listen checkboxes change event too. Try this code:
var $input = $('input'),
$check = $input.filter(':checkbox'),
$register = $('#signin');
$register.attr('disabled', true);
$input.on('keyup change', function() {
var trigger = false;
$input.each(function() {
if (this.type != 'checkbox' && !$(this).val()) {
trigger = true;
}
});
$register.prop('disabled', trigger || !$check.filter(':checked').length);
});
Demo: http://jsfiddle.net/jy3UR/1/
Your HTML is invalid. A <label> is closed which wasn't started and you have a duplicate ID 'chk'...
You need to put it in the onload event of the document and indeed as #dfsq already stated, you need to add a check for the checkboxes too, like so:
$(document).ready(function() {
var $input = $('input'),
$register = $('#signin');
$chk = $('input[type=checkbox]');
$register.attr('disabled', true);
$input.on('keyup change', function() {
var trigger = false;
$input.each(function() {
if (this.type != 'checkbox' && !$(this).val()) {
trigger = true;
}
});
$register.prop('disabled', trigger || !$chk.filter(':checked').length);
});
})
otherwise it will get executed when the DOM has not fully loaded yet and your fields will not be available...
DEMO
First of all you have used same id for both the check box.
rename it like below
<input id="chk1" type="checkbox" >chk1</label>
<input id="chk2" type="checkbox" >chk2</label>
and modify your code like below :
<script>
$(document).ready(function() {
var $input = $('input'),
$register = $('#signin');
$register.attr('disabled', true);
$input.keyup(function() {
var trigger = false;
$input.each(function() {
var checked = $("input[type='checkbox']:checked");
if(checked.length >0) // check if atleast one checkbox checked
trigger = true;
if(!trigger){
if(!$(this).val()) {
trigger = true;
}
}
});
trigger ? $register.attr('disabled', true) : $register.removeAttr('disabled');
});
});
</script>
You should try this simple solution :
jQuery(function($) {
$('form input').on('change',function() {
isDisabled = !(($('#txtusername').val().length > 0 && $('#txtpassword').val().length > 0) || $('input[type="checkbox"]:checked').length > 0);
$('#signin').attr('disabled', isDisabled);
});
});
It does its job.

chech/unchek all checkboxes (dynamically generated)

I have a view with checkboxes, generated dynamically, and a button for chech/unchek all the checkboxes. I try the code bellow but, the checkboxes are not checked ob button click event. Please help.
Thank you.
View with checkboxes:
<button id="selectinvert" name="selectinvert" class="clear-selection ui-btn-hidden" aria-disabled="false" > Select / Deselect All</button>
#for (int i = 0; i < #Model.workDaysList.Count; i++)
{
<div class="framed">
<div data-role="collapsible" data-collapsed="true" class="ui-btn-inner ui-corner-top ui-corner-bottom">
<h3>
<div class="ui-checkbox" id="checkbox">
<input type="checkbox" id="#Model.workDaysList[i][0]" />
<span class="ui-btn-text">
<label for="#Model.workDaysList[i][0]" data-theme="c">
#Model.workDaysList[i][1].Substring(6, 2)/#Model.workDaysList[i][1].Substring(4, 2)/#Model.workDaysList[i][1].Substring(0, 4)
</label>
</span>
</div>
</h3>
#Model.detailDaysList[i][0] / #Model.detailDaysList[i][1]
<br />
#Model.detailDaysList[i][2] / #Model.detailDaysList[i][3]
<br />
#Model.detailDaysList[i][4] h
</div>
</div>
</div>
}
Jquery code:
<script type="text/javascript">
$(document).ready(function () {
$("#selectinvert").click(function () {
$("INPUT[type='checkbox']").each(function () {
if (this.checked == false) {
this.checked = true;
} else {
this.checked = false;
}
});
});
});
</script>
Try This:
<script lang='javascript'>
$(document).ready(function(){
$('#selectinvert').click(function(){
$("input[type='checkbox']").each(function (){
if($(this).is(':checked')){
$(this).prop('checked', false);
}else{
$(this).prop('checked', true);
}
});
})
});
</script>
there are closing }) missing..
btw: the toggle can written like this:
this.checked = !this.checked
Try to start with a basic HTML code and build upon that! Your model code might be braking your HTML. You can find the working prototype here!
<button id="selectinvert" name="selectinvert" class="clear-selection ui-btn-hidden" aria-disabled="false" > Select / Deselect All</button>
<div class="framed">
<div class="ui-checkbox" id="checkbox">
<input type="checkbox" id="#Model.workDaysList[i][0]" />
<span class="ui-btn-text">First</span>
</div>
<div class="ui-checkbox" id="checkbox">
<input type="checkbox" id="#Model.workDaysList[i][0]" />
<span class="ui-btn-text">Second</span>
</div>
</div>
$("#selectinvert").click(function() {
$("INPUT[type='checkbox']").each(function() {
if (this.checked == false) {
this.checked = true;
} else {
this.checked = false;
}
});
});
As others suggest, you were missing closing brackets.
You could also shorten your code a bit:
$("#selectinvert").click(function() {
$("input[type='checkbox']").each(function() {
this.checked = !this.checked;
});
});
Also note that your problem has nothing to do with ASP.NET or jQuery UI.
​
try
$("#selectinvert").click(function () {
$("INPUT[type='checkbox']").each(function () {
if (!$(this).is(":checked")) {
$(this).attr('checked','checked');
} else {
$(this).removeAttr('checked','checked');
}
})
});
I think the code you have written will only only work when all the checkboxes are either checked or unchecked..
What happens when some of them are checked.. Your code will just toggle those..
Your logic should be dependent on the button and not the checkboxes..
$(document).ready(function() {
var isChecked = false;
$("#selectinvert").click(function() {
var $checkboxes = $("INPUT[type='checkbox']") ;
if(isChecked){
isChecked = false;
}
else{
isChecked = true;
}
$checkboxes.prop('checked' , isChecked);
});
});​
