I have the following form and I need that after the user clicks Save, an error message shows next to the radio group that is required (but no radio selected). I tried the following but it doesn't show the message at all.
<form #formList="ngForm" (ngSubmit)="Save(formList)">
<div *ngFor="let item of data">
<p>{{item.name}}</p>
<input type="radio" name="{{item.id}}" [value]="1" [(ngModel)]="item.isSelected" required>Foo
<input type="radio" name="{{item.id}}" [value]="2" [(ngModel)]="item.isSelected">Bar
<div *ngIf="formList.controls.item?.id.required">
The radio is required!
</div>
</div>
<button type="submit">Save</button>
</form>
Try this code
<form #formList="ngForm" (ngSubmit)="Save(formList)">
<div *ngFor="let item of data">
<p>{{item.name}}</p>
<input type="radio" name="{{item.id}}" [value]="1" [(ngModel)]="item.isSelected" required>Foo
<input type="radio" name="{{item.id}}" [value]="2" [(ngModel)]="item.isSelected">Bar
<div *ngIf="!formList.form.valid">
The radio is required!
</div>
</div>
<button type="submit">Save</button>
</form>

I use SpringBoot, Thymeleaf.
I want to update the value only for part of form in update page.
<form id="form" class="needs-validation col-sm-6" th:action="#{'/user/edit/' + ${userInfo.id}}" th:object="${userInfo}" method="post" novalidate>
<input type="hidden" name="_method" value="put"/>
<input type="hidden" name="id" th:value="${userInfo.id}"/>
<div class="form-group">
<label for="name">Name</label>
<h4 id="name" th:text="${userInfo.name}" th:value="${userInfo.name}"></h4>
<input type="hidden" name="name" th:value="${userInfo.name}"/>
</div>
<hr>
<div class="form-group">
<label for="nickname">Nickname</label>
<input id="nickname" type="text" name="nickname" th:value="${userInfo.nickname}" placeholder="enter nickname" required minlength="2">
</div>
<hr>
<div class="form-group">
<label for="volunteerTime">Volunteer Time</label>
<span id="volunteerTime" th:text="${userInfo.volunteerTime}+'hour'" name="volunteerTime" th:value="${userInfo.volunteerTime}"></span>
<input type="text" size="5px" placeholder="hour"/>
<button type="button" name="action" value="plus" onclick="ajax()">plus</button>
<button type="button" name="action" value="minus" onclick="ajax()">minus</button>
</div>
<div class="form-group">
<input type="submit" value="update">
</div>
</form>
The "volunteerTime" section of the above code seeks to update and show values added to existing data according to the number entered.
The same goes for Minus.
In This form I have to access the control of formControlName="last" to show errors of it.
<div [formGroup]="form">
<div formGroupName="name">
<input formControlName="first" placeholder="First name">
<input formControlName="last" placeholder="Last name">
<span *ngIf="name['controls'].last.invalid">invalid</span>
</div>
<input formControlName="email" placeholder="Email">
<button type="submit">Submit</button>
</div>
This code has thrown an error 'controls' of undefined(Bold Formatted line).
control could be accessible by form['controls'].name['controls'].last.invalid , but is there any way I could access the control directly by its formGroupName ?
Thanks in Advance
Try this
<div *ngIf="!form.controls.name.controls.last.valid">
Invalid last name !!
</div>
Could you try below snippet
<span *ngIf="form.get('last').invalid">invalid</span>
#sravanponugoti: we cannot use [formGroup] with in angular.
Try this code
<form [formGroup]="form">
<div formGroupName="name">
<input formControlName="first" placeholder="First">
<input formControlName="last" placeholder="Last">
<span *ngIf="form.controls['name'].controls.last.valid">invalid</span>
</div>
<input formControlName="email" placeholder="Email">
<button type="submit">Submit</button>
</form>
I am trying to submit a form in a bootstrap framework and cannot get past the validation, even with correct data.
I think there might be an error with this syntax,
<form name=form1 method=post action=signupck.php onsubmit='return validate(this)'><input type=hidden name=todo value=post>
then the form fields... which all display correctly - so no problems there - in the style:
<div class="row">
<div class="col-xs-2">
<label for="fname">Forename</label>
<input type="text" class="form-control" id="fname" placeholder="Forename"><br></br>
</div>
<div class="col-xs-2">
<label for="sname">Surname</label>
<input type="text" class="form-control" id="sname" placeholder="Surname">
</div>
</div>
and then,
<input type=submit value=Signup>
<input type="reset" class="btn btn-default" value="Reset">
The form on submission displays signupck.php, signalling validation messages when is should be submitted ok. I have got this working outside the bootstrap, but when I put this inside the template, in the form above, I get the problems.
Any help would be most appreciated.
I am trying to use the ng-required in a form.
All I did was add ng-required="true" on my input.
In Chrome, when clicking submit it prevents submission and asks the user to fill the field, as expected. On an iPhone, it doesn't show any error and it executes the submit function.
<form name="addGuest" ng-submit="GLCtrl.addGuest()">
<div class="form-group">
<label for="newGuestFirstName">First Name</label>
<input type="text" id="newGuestFirstName" ng-model="GLCtrl.newGuest.firstName" class="form-control" required="true"/>
</div>
<div class="form-group">
<label for="newGuestLastName">Last Name</label>
<input type="text" id="newGuestLastName" ng-model="GLCtrl.newGuest.lastName" class="form-control" required="true"/>
</div>
<div class="form-group">
<label for="arrivalDate">Arrival Date</label>
<div class="input-group">
<input type="text" id="arrivalDate" class="form-control" datepicker-popup="yyyy-MM-dd" ng-model="GLCtrl.newGuest.arrivalDate" is-open="opened" required="true" close-text="Close"
/>
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="open($event)"><i class="glyphicon glyphicon-calendar"></i></button>
</span>
</div>
</div>
<button type="button" class="btn btn-default" ng-click="GLCtrl.cancelAdd()"><i class="glyphicon glyphicon-remove"></i></button>
<button type="submit" class="btn btn-default"><i class="glyphicon glyphicon-ok"></i></button>
</form>
You need to check if the form is valid before proceeding to your form submission process. In regards to your problem, you are probably relying on HTML5's required attribute which is added when ng-required is true. This might work on chrome but it partially works in IOS.
See the note on this link
Partial support in Safari refers to lack of notice when form with required fields is attempted to be submitted. Partial support in IE10 mobile refers to lack of warning when blocking submission.
Solution:
Add novalidate in your form, don't use the HTML5 required attribute messaging which is only useful for some browsers. Show required error message explicitly.
Sample HTML implementation:
<form name="form" ng-submit="submit(form, user)">
<input type="email" required name="email" ng-model="user.email">
<div ng-show="form.email.$error.required>This field is required</div>
<input type="password" required name="password" ng-model="user.password">
<div ng-show="form.password.$error.required>This field is required</div>
<button type="submit">Login</button>
</form>
Sample Controller implementation:
$scope.submit = function(form, user) {
if(form.$valid) { // guard against any errors
// do you login process here..
}
};
Additionally, you can also use the ng-disabled approach to disable the submit button when when form is invalid.
<button type="submit" ng-disabled="form.$invalid">Login</button>
UPDATE:
This update takes into consideration that you are using twitter bootstrap3. By using the following classes: 'has-error' for form-groups and 'help-block' for showing the error messages. By using the ng-class and ng-show directives in showing the errors with angular form validation indicators mentioned in each angular input directives and the FormController and NgModelController documentation and also the guides shown in the developer's guide.

With succes I've created a page that uses the set of radio buttons that are formatted jquery. But as soon as I add the div's need to position the content on the page, the radio buttons are still formatted, but do not act as radio buttons anymore (they act like checkboxes). This is my code, what's wrong with it?
<script>
$(document).ready(function() {
$("#dt_hel").buttonset();
});
</script>
<!-- end script radiobuttons -->
<div class="demo">
<div id="ContentContainerLeft" >
<form id="dt_this_form" name="dt_this_form" action="this.php" method="post">
<p>
</div>
<div id="ContentContainerMiddle" >
<P>
<div id="dt_hel" style="font-size:80%;">
<input type="radio" id="radio1" name="dt_hel" value="0" /><label for="radio1">Lower</label>
<input type="radio" id="radio2" name="dt_hel" value="1" /><label for="radio2">Equal</label>
<input type="radio" id="radio3" name="dt_hel" value="2" checked/><label for="radio3">Higher</label>
</div>
<P></P>
</div>
<div id="TweetContainer" >
<P>
</div> <!-- end tweetcontainer -->
</div><!-- End demo -->
</form>
If you follow the rule of closing the most recent tag before closing older tag (ie set the form opening tag above the tag) then it should work e.g.
<form id="dt_this_form" name="dt_this_form" action="this.php" method="post">
<div class="demo">
<div id="ContentContainerLeft" >
<p>
</div>
<div id="ContentContainerMiddle" >
<P>
<div id="dt_hel" style="font-size:80%;">
<input type="radio" id="radio1" name="dt_hel" value="0" /><label for="radio1">Lower</label>
<input type="radio" id="radio2" name="dt_hel" value="1" /><label for="radio2">Equal</label>
<input type="radio" id="radio3" name="dt_hel" value="2" checked/><label for="radio3">Higher</label>
</div>
<P></P>
</div>
<div id="TweetContainer" >
<P>
</div> <!-- end tweetcontainer -->
</div><!-- End demo -->
</form>
