I have the following html
<div class="row">
<div class="col-lg-6">
<label class="radio">
<input type="checkbox">
</label>
</div>
<div class="col-lg-1">
<input type="text" disabled="" class="col-lg-2 form-control" name="notes_33">
</div>
</div>
there is an on click event on the checkbox input in "col-lg-6" div, i want to get the value input text under "col-lg-1", here is my way to get it
$("#medication").on('click', ':checkbox', function(){
var $note = $(this).parent().parent().siblings('.col-lg-1').find(":text");
//... change the value of $note
});
is my way is good? is there any better way to traverse to the input filed starting from the check box?
This looks like simpler:
$(this).closest('.row').find(':text')
Edit:
Here is the comparisons between closest and parents:

I have the following radiobuttons:
<div class="nextgen-goal-overall-radiobuttons pull-left">
<label class="nextgen-input-label">Overall Goal</label>
<div class="radio-button-item pull-left" *ngFor="let goalType of goalTypesRadioButton">
<p-radioButton class="nextgen-radio-button" name="{{goalType.id}}" value="{{goalType.id}}" label="{{goalType.description}}" [(ngModel)]="selectedGoalTypeId"></p-radioButton>
</div>
</div>
When I click on any radio button the selectedGoalTypeId is updated with the corresponding value.
My problem here is that on my HTML I have the following conditional divs:
<div class="nextgen-input-container nextgen-goal-input pull-left">
<span *ngIf="selectedGoalTypeId === 1" class="goals-currency-icon">{{currencyFormat}}</span>
<label class="nextgen-input-label nextgen-target-group-label">{{selectedGoalTypeId}}</label>
<input class="nextgen-input" [class.nextgen-input-budget] = "selectedGoalTypeId === 1" type="number" pInputText placeholder="">
</div>
<div *ngIf="selectedGoalTypeId === 3" class="nextgen-goal-frequency-dropdown pull-left">
<label class="nextgen-input-label nextgen-target-group-label">Frequency</label>
<p-dropdown [showTransitionOptions]="'0ms'" [hideTransitionOptions]="'0ms'" dropdownIcon="fa fa-angle-down" class= "nextgen-dropdown" [options]="FrequencyLookup" [(ngModel)]="selectedFrequency" value="selectedFrequency"></p-dropdown>
</div>
Asking if selectedGoalTypeId is 1 or 3 it shows some divs or not.
The problem here is that the selectedGoalTypeId is updated correctly. I put some label on the HTML to check. But the divs are not changed according to the conditions it always displays the same despite of the value of selectedGoalTypeId. What I'm missing here?
In p-radioButton change value="{{goalType.id}}" to [value]="goalType.id"
And I suppose that *ngIf="selectedGoalTypeId === 1" should be placed on the upper div than on the span
Posted the solution Here
PS : I guess goalType.id and selectedGoalTypeId are both number
I have A form with several Items, including some check boxes that need to receive their status from the data service/ a model.
<div class="col">
<label for="expired">IsExpired</label>
<div>
<input type="checkbox" id="expired" disabled>
</div>
</div>
this is in the class of card.model.ts
expired: boolean;
and data.service.ts:
new CardModel('4',new Duration(2, 0), new LessonModel('#5DC878', 'Bialogy'), 'just the first part', false,true,new Date(2018,11,11,13,30),new Date(2018,11,11),true,false)
I have tried to put [(ngModel)] = "expired" into the input tag but I receive an error:
Can't bind to 'ngModel' since it isn't a known property of
'input'
what is the problem?
Try this:-
html
<div class ="col">
<label for="expired">IsExpired</label>
<div>
<input type="checkbox" id="expired" [checked]="checkedStatus">
<input type="checkbox" [(ngModel)]="checkedStatus" name="ele_name"/> <=== add name
</div>
</div>
ts
checkedStatus = true;
I used to implement an Angular 2/4 application with Bootstrap 3 and used the Reactive Forms approach. I had a field-validation where the border of the input-field turned red and an error message appeared under the field in red font color.
it looks like this:
<div class="form-group row"
[ngClass]="{'has-error': (sourcesForm.get('sourceName').touched ||
sourcesForm.get('sourceName').dirty) &&
!sourcesForm.get('sourceName').valid }">
<label class="col-md-2 col-form-label"
for="sourceNameId">Source Name</label>
<div class="col-md-8">
<input class="form-control"
id="sourceNameId"
type="text"
placeholder="Source Name (required)"
formControlName="sourceName" />
<span class="help-block" *ngIf="(sourcesForm.get('sourceName').touched ||
sourcesForm.get('sourceName').dirty) &&
sourcesForm.get('sourceName').errors">
<span *ngIf="sourcesForm.get('sourceName').errors.required">
Please enter the Source Name.
</span>
<span *ngIf="sourcesForm.get('sourceName').errors.minlength">
The Source Name must be longer than 3 characters.
</span>
<span *ngIf="sourcesForm.get('sourceName').errors.maxlength">
The Source Name is too long.
</span>
</span>
</div>
</div>
Now i have to use Bootstrap 4 and neither the error message or the input-field turns red. How do i realise this? I tried to change the class of the parent span-block to "form-text" but it didn't work.
For beta version of Bootstrap v4, you can check out Form validation docs. There you can read about the new way, supported by all modern browsers for HTML5 way of form-validation with valid/invalid css classes. There Bootstrap uses the .was-validated and .invalid-feedback classes for what you want to achieve (see code snippet).
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/css/bootstrap.min.css" rel="stylesheet"/>
<form class="container" id="needs-validation" novalidate>
<label for="validationCustom02">Last name</label>
<input type="text" class="form-control" id="validationCustom02" placeholder="Last name" value="Otto" required>
<label for="validationCustom03">City</label>
<input type="text" class="form-control" id="validationCustom03" placeholder="City" required>
<div class="invalid-feedback">
Please provide a valid city.
</div>
<button class="btn btn-primary" type="submit">Submit form</button>
</form>
<script>
// Example starter JavaScript for disabling form submissions if there are invalid fields
(function() {
"use strict";
window.addEventListener("load", function() {
var form = document.getElementById("needs-validation");
form.addEventListener("submit", function(event) {
if (form.checkValidity() == false) {
event.preventDefault();
event.stopPropagation();
}
form.classList.add("was-validated");
}, false);
}, false);
}());
</script>
If you want something more similar to Bootstrap 3, you can use what they call server-side validation, as it is written:
As a fallback, .is-invalid and .is-valid classes may be used instead of the pseudo-classes for server side validation. They do not require a .was-validated parent class.
Previous answer for alpha version of Bootstrap V4 (if you must use this).
On Bootstrap V4 Form Validation Docs there is the following example:
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" rel="stylesheet"/>
<div class="form-group has-danger">
<label class="form-control-label" for="inputDanger1">Input with danger</label>
<input type="text" class="form-control form-control-danger" id="inputDanger1">
<div class="form-control-feedback">Sorry, that username's taken. Try another?</div>
<small class="form-text text-muted">Example help text that remains unchanged.</small>
</div>
So i think you just need to change the has-error class to has-danger
This is the solution:
<div class="form-group row">
<label class="col-md-2 col-form-label"
for="sourceNameId">Source Name</label>
<div class="col-md-8">
<input class="form-control"
[ngClass]="{'is-invalid': (sourcesForm.get('sourceName').touched ||
sourcesForm.get('sourceName').dirty) &&
!sourcesForm.get('sourceName').valid }"
id="sourceNameId"
type="text"
placeholder="Source Name (required)"
formControlName="sourceName" >
<span class="invalid-feedback" *ngIf="(sourcesForm.get('sourceName').touched ||
sourcesForm.get('sourceName').dirty) &&
sourcesForm.get('sourceName').errors">
<span *ngIf="sourcesForm.get('sourceName').errors.required">
Please enter the Source Name.
</span>
<span *ngIf="sourcesForm.get('sourceName').errors.minlength">
The Source Name must be longer than 3 characters.
</span>
<span *ngIf="sourcesForm.get('sourceName').errors.maxlength">
The Source Name is too long.
</span>
</span>
</div>
</div>
i needed to put the [ngClass]into the input-tag. Then i had to define the class as is-invalid and set the parent span-class to invalid-feedback
i know that your question is for long time ago, but it is the best way to validate the form-control input field by reactive form technique and bootstrap 4 to display the validation. first you need to write some code for your form :
in html section:
<form [formGroup]="myForm">
<div class="form-group">
<label for="name">first Name: </label>
<input type="text" class="form-control" formControlName="firstName" id="name">
<div *ngIf="firstName.touched && firstName.invalid" class="alert alert-danger">
<div *ngIf="firstName.errors.required">filling name is required!</div>
</div>
</div>
in ts file, you should implement the logic to conduct the validation.
in ts file:
myForm = new FormGroup({
'firstName':new FormControl('',Validators.required)
})
//getter method
get firstName(){
this.myForm.get('firstName');
}
now you can see that the validation is working. now to give style to input field to show the red border around the invalid input, just go to css file of component and add this class to the css file:
.form-control.ng-touched.ng-invalid{border:2px solid red;}
and simply you can see the result.
I have an array like below
standardInput:any = [{val:'1'},{val:'2'},{val:'3'}];
When i loop it in my view
<div class="form-group row text-right" *ngFor='let row of standardInput' >{{row.val}}
<label class="col-sm-3 form-control-label m-t-5" for="password-h-f"></label>
<div class="col-sm-9 form-control-label m-t-5" for="password-h-f">
<div class="row">
<div class="col-sm-9" >
<input class="form-control" name="roles" [formControl]="form.controls['service_standard_sub_heading']" [(ngModel)]="row.val" id="email-h-t" type="email">
</div>
<div class="col-sm-3">
<button class="btn btn-danger" (click)="removeInputs('standard',i)">Remove</button>
</div>
</div>
</div>
</div>
The output is :3 3 3,it is showing only the last object in the array for the 3 iterations.I am not able to understand what's the reason.Can anyone please suggest help.Thanks.
I believe you are using template-driven form, if not, let me know and we can look at a solution for model-driven form :)
In forms, the name attribute needs to be unique. Even though the ngModel is unique, Angular doesn't really care about it, but looks at the name attribute instead. Since you are using a template-driven form and ngModel, I see no need to use formControl here, you can just rely on the the ngModel and name attribute instead. So, to get the unique name attribute, we can bind the row.val to it, like so:
[name]="row.val"
So your complete template would look like this:
<form #form="ngForm">
<div class="form-group row text-right" *ngFor='let row of standardInput'>
<input class="form-control" [name]="row.val" [(ngModel)]="row.val">
</div>
</form>
This is my HTML code. It's a custom DropDownList that I made. Can someone advise how I could set one of the options to be checked by default in this case below?
<div class="dropdownlistheader" ng-click="toggle('subdiv','item')">
<input type="text" readonly="readonly" class="dropdownlistinput" value="{{selectedItemValuesDisplay}}" />
</div>
<div id="ddl123" ng-show="showItemOptions" class="dropdownlist">
<div ng-show="showItemOptions" ng-repeat="option in ItemTypeDDL">
<input type="checkbox" ng-model="selected[$index]" ng-click="toggleItemSelection(option.TypeID, option.TypeName)"> {{option.TypeName}}
</div>
</div>
Based on the limited details provided in the questions, I'll suggest the following:
<div id="ddl123" ng-show="showItemOptions" class="dropdownlist" ng-init="selected[0] = true">
<div ng-show="showItemOptions" ng-repeat="option in ItemTypeDDL">
<input type="checkbox" ng-model="selected[$index]" ng-click="toggleItemSelection(option.TypeID, option.TypeName)"> {{option.TypeName}}
</div>
</div>
The ngInit directive will select the first element in the selected flags list, by setting the first index of the array to true
