I have this code and I need to pass the text to the tooltip whether checkbox is active or not, so this will display eg. "active" when checkbox is active and "disactive" when not. How to do that?
<div class="wifi__switcher switcher">
<input type="checkbox" [id]="wifiIdentifier" class="input switcher--input js-checkbox" [checked]="activated" (click)="saveState()">
<label class="switcher--label" [for]="wifiIdentifier" matTooltipPosition="above" matTooltip="(tooltipMessageAccordingToCheckboxState)">Toggle</label>
<!--</div>-->
</div>
DEMO
HTML:
<div class="wifi__switcher switcher">
<input type="checkbox" class="input switcher--input js-checkbox" [checked]="activated" (change)="saveState($event)">
{{activated}}
<label matTooltipPosition="above" matTooltip="{{activated?'activated': 'not active'}}">Toggle</label>
</div>
TS:
activated: boolean = false;
saveState(ev){
if(ev.target.checked){
this.activated = true
} else{
this.activated = false
}
}

I would like to change a boolean value inside the component file with a simple checkbox. If it is not checked it should remain false, otherwise it should be true.
Component:
export class UsersComponent {
public Personal: boolean = false;
}
HTML:
<label>
<input type="checkbox" name="Personal" [(ngModel)]="Personal"/>
Personal
</label>
Since you have added 2 way binding in html [(ngModel)]="Personal", it should assign automatically
check via
<label>
<input type="checkbox" name="Personal" [(ngModel)]="Personal"/>
{{Personal}}
</label>
You can use these to toggle the value of the Personal
HTML:
<label>
<input type="checkbox" [checked]="Personal" (change)="mPersonal = !Personal" /> Checked + Change
{{Personal}}
</label>
Correct For 2 way binding :
<label>
<input type="checkbox" name="Personal" [(ngModel)]="Personal" />
{{Personal}}
</label>
I am new to ionic 2 and I could not find a proper solution for this.I have two radio buttons in my signup form. I need to enable two in put fields based on the radio button that is clicked. If radio button one is clicked input field one should be enabled.
Radio buttons
<div radio-group formGroupName="church">
<label>Church</label>
<div>
<label>CGT</label>
<ion-radio value="cgt" ></ion-radio>
<label>Other church</label>
<ion-radio value="noncgt"></ion-radio>
</div>
</div>
<div>
Input fields
<div>
<label>CGT member ID </label>
<input formControlName="cgtMemberID" type="text" disabled="true">
<small [hidden]="myForm.controls.cgtMemberID.valid || (myForm.controls.cgtMemberID.pristine && !submitted)">
member ID required .
</small>
</div>
<div>
<label>Church Name </label>
<input formControlName="churchName" type="text" disabled="true">
<small [hidden]="myForm.controls.churchName.valid || (myForm.controls.churchName.pristine && !submitted)">
Church name required .
</small>
</div>
I think you need this:
1- in html:
<div radio-group>
<label>Church</label>
<div>
<label>CGT</label>
<ion-radio value="cgt" (ionSelect)="radio_select('cgt')"></ion-radio>
<label>Other church</label>
<ion-radio value="noncgt" (ionSelect)="radio_select('noncgt')"></ion-radio>
</div>
</div>
<div>
<label>CGT member ID </label>
<input type="text" [disabled]="cgt">
</div>
<div>
<label>Church Name </label>
<input type="text" [disabled]="cn">
</div>
2- and in .ts file:
cgt: boolean = true;
cn: boolean = true;
radio_select(value) {
if (value == 'cgt') {
this.cgt = false;
this.cn = true;
} else if (value == 'noncgt') {
this.cgt = true;
this.cn = false;
}
}
you also can add your form logic.
<div>
ToDo<br>
<input ng-show="add" type="checkbox" >{{val}}
</div>
<div>
<input type="text" ng-model="ToDo">
<input type="button" ng-click="addToDo()" name="btn" placeholder="add todo here" ng-model="add" value="add" />
</div>
And the javascript:
var app = angular.module("myapp",[]);
app.controller("myctrl",function($scope,$log){
$scope.addToDo = function(){
$scope.val = $scope.ToDo;
}
});
If i click on the 'add' button, a checkbox should appear along with the text of the texxtbox. But only text is showing, no checkbox. How do i display the checkbox?
You have to call the function in your controller and update some variable to true/ false. Based on the value and using ng-if directive, you can toggle the HTML element.
$scope.displayCheckBox = false;
$scope.val = "someRandoValue";
$scope.addToDo = function() {
$scope.displayCheckBox = true;
};
<div>
ToDo<br>
<span ng-if="displayCheckBox">
<input type="checkbox" >{{val}}
</span>
</div>
The following form shows a list of data on submit. I am trying to show no results found when there is no data on submit. I tried like shown below,it shows and hides the div. But when there is no options selected on form and click submit button it shows the no result div.How to show the no results div only when form validation succeeds and there is no data to display.
HTML
<div class="form-group" >
<label class="radio-inline">
<input name="sampleinlineradio" value="3" type="radio" ng-model="radioption"
ng-required="!radioption"> MAIN 1</label>
<label class="radio-inline">
<input name="sampleinlineradio" value="1" type="radio" ng-model="radioption" >
Main 2</label>
<div ng-show="!radioption && buttonClicked">Please select one.</div>
</div>
<div class="form-group">
<label ng-repeat="branch in branches">
<input type="checkbox" name="selectedBranches[]" value="{{branch.value}}"
ng-model="branch.selected" ng-required="isOptionsRequired()" >
{{branch.name}}</label>
<div ng-show="isOptionsRequired() && buttonClicked">Please select one.</div>
</div>
<input type="button" ng-click="fetchresults()" value="submit" >
<div ng-show="buttonClicked">
<table> <thead>.....</thead>
<tbody>
<tr ng-show="results.length!=0" ng-repeat="r in results">
<td></td></tbody></table>
</div>
<div ng-show="buttonClicked">
<span ng-show="results.length==0 ">No results.</span>
</div>
Minimal Controller Code
$scope.fetchresults = function(){
$scope.results = Result.query({main: $scope.radioption, branch: $scope.selection[0], });
$scope.buttonClicked = true;
}
EDIT:
I used model to validate and $valid is also working, as suggested below.But Got a couple of glitches. If i click the button it does not show div. but after validation is over it shows automatically "no results" from the click before. How to stop this.And while it lists data when its available it shows "no results" for a second or so
Give your form a name
<form name="formName">
Then you can do
ng-show="results.length==0 && formName.$valid"
Some more information on angularJS form validation
You can check the below snippet, I have changed most of them in angular way with $invalid, $pristine, $submitted and $valid.
You can check the angular documentation to read about them.
Link 1, Link 2
Note: You can use a submit button and get rid of ng-click event and use ng-submit instead which can't be used in this snippet as form submit is not allowed. Comment the line form.$submitted = true; when you use a submit button.
var app = angular.module('app', []);
app.controller('TestController', function($scope){
$scope.isFieldInvalid = function(field) {
var form = $scope.testForm;
return form[field].$invalid && (!form[field].$pristine || form.$submitted);
};
$scope.fetchResults = function(){
var form = $scope.testForm;
form.$submitted = true; // comment this line if button type="submit"
if(form.$valid){
$scope.searching = true;
$scope.results = [];
var rnd = Math.random();
if(rnd >= 0.5) {
$scope.results = [{id: 1}, {id: 2}];
}
//$scope.results = Result.query({main: $scope.radioption, branch: $scope.selection[0], });
$scope.buttonClicked = true;
$scope.searching = false;
}
};
});
angular.bootstrap(document, ['app']);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

I am trying to associate a radio input with a specified text input. As you can see in the picture, there are two options. I know I can use for="" to associate the label to the radio input, but how can I also associate it to the text input underneath, and vise versa so when I focus on the text input, if focuses the correct radio button?
NOTE: The amount entered will be inserted into the database, so that's the most important part of this form. Currently if I click on $Off, I can still enter a number in %Off. I don't want this to happen, so the user does not get confused.
My markup:
<div class="row-fluid control-group">
<div class="span7 pull-left">
<label class="radio" for="discount-dollars">
<input type="radio" name="discount" id="discount-dollars" value="dollars" checked="checked">
$ Off
</label>
<div class="input-append">
<input type="text" name="discount-dollars-amount" id="discount-dollars-amount" class="input-small dollars" placeholder="enter amount">
<span class="add-on">.00</span>
</div>
</div><!-- .span7 .pull-left -->
<div class="span5">
<label class="radio" for="discount-percent">
<input type="radio" name="discount" id="discount-percent" value="percent">
% Off
</label>
<input type="text" name="discount-percent-amount" id="discount-percent-amount" class="input-small percent" placeholder="enter amount" disabled="disabled">
</div>
</div><!-- .row-fluid .control-group -->
<script type="text/javascript">
$(function (){
$("form input[type=radio]").click(function (){
// get the value of this radio button ("dollars" or "percent")
var value = $(this).val();
// find all text fields...
$(this).closest("form").find("input[type=text]")
// ...and disable them...
.attr("disabled", "disabled")
// ...then find the text field whose class name matches
// the value of this radio button ("dollars" or "percent")...
.end().find("." + value)
// ...and enable that text field
.removeAttr("disabled")
.end();
});
});
</script>
You can't use a single <label> element to label two separate inputs. I would suggest associating the labels to the radio buttons, since the radio button is such a small click target and the label expands that target.
Choose one of the radios to be selected by default, perhaps "$ Off". Disable the other text field by default:
<div class="row-fluid control-group">
<div class="span7 pull-left">
<label class="radio" for="discount-dollars">
<input type="radio" name="discount" id="discount-dollars" value="dollars" checked="checked">
$ Off
</label>
<div class="input-append">
<input type="text" name="discount-dollars-amount" id="discount-dollars-amount" class="input-small dollars" placeholder="enter amount">
<span class="add-on">.00</span>
</div>
</div><!-- .span7 .pull-left -->
<div class="span5">
<label class="radio" for="discount-percent">
<input type="radio" name="discount" id="discount-percent" value="percent">
% Off
</label>
<input type="text" name="discount-percent-amount" id="discount-percent-amount" class="input-small percent" placeholder="enter amount" disabled="disabled">
</div>
</div><!-- .row-fluid .control-group -->
Then use jQuery to do something like this:
$(function (){
$("#discount-dollars, #discount-percent").click(function (){
// get the value of this radio button ("dollars" or "percent")
var value = $(this).val();
// find all text fields...
$(this).closest(".control-group").find("input[type=text]")
// ...and disable them...
.attr("disabled", "disabled")
// ...then find the text field whose class name matches
// the value of this radio button ("dollars" or "percent")...
.end().find("." + value)
// ...and enable that text field
.removeAttr("disabled")
.end();
});
});
Basically, this listens for click events on both radio buttons. When you click one radio, it enables its associated text field (i.e., the text field with a CSS class name matching the value of the radio button) and disables the other text field. That way, you can't enter text into either text field unless its associated radio button is checked.
use image radio button with 2 states, selected and not selected, when you click the radio image just set focus to the textbox and swap to your selected radio image, and vice versa.
You cannot focus on two elements, it will be either the input text field or the radio button.
But you should use JavaScript or jQuery, when you click on the radio button to focus on the field below, or when you enter value in the field below to check the radio button above.
This can help you if you want to use jquery : http://api.jquery.com/val/ and http://api.jquery.com/focus/
This is a VERY rough sketch to help you out, but you could do something like this (giving you follow a certain naming convention):
<input type="radio" name="rGroup" id="radioDollarOff" onclick="changeMe(this);"/> <input type="text" name="textDollarOff" id="textDollarOff" onclick="changeMe(this);"/>
<br />
<input type="radio" name="rGroup" id="radioPctOff" onclick="changeMe(this);"/> <input type="text" name="textPctOff" id="textPctOff" onclick="changeMe(this);"/>
<script>
function changeMe(inField) {
var fieldId = inField.id;
var type = fieldId.substring(0, 4);
if(type == 'text') {
var name = fieldId.substring(4);
var radioButton = document.getElementById("radio" + name);
radioButton.checked = true;
}else {
var name = fieldId.substring(5);
var textField = document.getElementById("text" + name);
textField.focus();
}
}
</script>
jQuery is what you want. Assuming your elements had IDs as follows:
$ radio button: money-radio
$ text box: money-text
% radio button: percent-radio
% text box: percent-text
...the code might look something like this. This will take care of disabling text boxes and focusing input properly.
<form>
<table>
<tr>
<td>
<input type="radio" id="money-radio" name="unit" value="money" />
<label for="money-radio">$ Off</label>
</td>
<td>
<input type="radio" id="percent-radio" name="unit" value="percent" />
<label for="percent-radio">% Off</label>
</td>
</tr>
<tr>
<td>
<input type="text" id="money-text" name="money-off" />
</td>
<td>
<input type="text" id="percent-text" name="percent-off" />
</td>
</tr>
</table>
</form>
<script type="text/javascript">
$(function() {
$('#percent-radio, #money-radio').change(function() {
if ($('#percent-radio').val() == true) {
$('#percent-text').removeAttr('disabled').focus();
} else {
$('#percent-text').attr('disabled', 'disabled');
}
if ($('#money-radio').val() == true) {
$('#money-text').removeAttr('disabled').focus();
} else {
$('#money-text').attr('disabled', 'disabled');
}
}).change();
});
</script>
