I'm trying to validate a phone number using the ngMessages and ngMessage directives, but I am facing two problems:
The "Invalid Input" message is shown only after the pattern's expression is met and the user continued typing.
The "required" message is not shown when the input is empty.
I want the "Invalid Input" to be shown as soon as the user starts typing, and not only after the pattern is met.
I don't understand what is wrong with my code, so I'd appreciate any help.
<form name="PhoneForm">
<div>
<md-icon md-svg-src="icons/ic_phone_48px.svg"></md-icon>
<md-input-container>
<label>Phone</label>
<input ng-model="contactPhone" name="PhoneInput" required ng-pattern="/^(05){1}[0-9]{8}$/"/> <!-- i.e 05x-xxxxxxx -->
<div ng-messages="PhoneForm.PhoneInput.$error" ng-if="PhoneForm.PhoneInput.$dirty">
<div ng-message="required">This field is required!</div>
<div ng-message="pattern">Invalid Input!</div>
</div>
</md-input-container>
</div>
Thank you

Not sure why I'm getting the following message. Has anyone else encountered this in AngularJS/Angular Material? What am I doing wrong? The message itself seems a little vague.
mdInput messages show animation called on invalid messages element:
md-input-container.md-block.md-icon-right.md-default-theme.md-input-has-value
Old question, but just in case anyone bumps into this, you need to supply an error message for the input field. The error is saying that it can't animate the error message into view because the messages element is missing.
In your md-input-container include the ng-messages element to handle the error. For example, if you have a form called myFrm with a required email address input named email, your code would be something like this:
<form name="myFrm">
<md-input-container>
<label>Email Address</label>
<input type="email" ng-model="myFrm.email" name="email" required/>
<div ng-messages="myFrm.email.$error">
<div ng-message="required">Email address is required</div>
</div>
</md-input-container>
<!-- Other form elements.... -->
</form>
I'm using angular-messages to display form validation errors on my angular app.
As per the documentation, I have built the following code
<form name="loginForm">
<label class="item item-input">
<input type="email" placeholder="Email" ng-model="data.email" name="email" required>
</label>
<div ng-messages="loginForm.email.$error" style="color:maroon">
<div ng-message="required">Please input a valid e-mail address</div>
<div ng-message="email">You did not enter your email address correctly...</div>
</div>
</form>
I have included the ngMessages directive in my javascript as well as imported the angular-messages.js file.
Unfortunately, these two messages are showing perpetually. Regardless of what I type in the input field, be it a valid email or not. Both messages are always showing. If I try to only include one ng-message, the result is the same.
What could I be doing wrong?
edit: In case my description isn't very clear, this is a print of the result

You gotta make sure you are actually including ngMessage to your module.
var app = angular.module('app', [
'ngMessages'
])
... and that you included the library to your project
<script src="/scripts/vendors/angular-messages/angular-messages.js"></script>
Everything seems to be fine in the code you're sharing.
<form name="loginForm">
<label class="item item-input">
<input type="email" placeholder="Email" ng-model="data.email" name="email" required>
</label>
<div ng-messages="loginForm.email.$error" style="color:maroon">
<div ng-message="required">Please input a valid e-mail address</div>
<div ng-message="email">You did not enter your email address correctly...</div>
</div>
</form>
Here is a working copy on Plunker I'm using your piece of code.
From Angularjs documentation.
By default, ngMessages will only display one error at a time. However, if you wish to display all messages then the ng-messages-multiple attribute flag can be used on the element containing the ngMessages directive to make this happen.
If you want to show the errors after the field is dirty, please visit this link.
Make sure you are including ngMessage module and the library as well. Please see Carlos's answer.
Thanks
Check with
<div ng-messages="loginForm.email.$error" ng-show="loginForm.email.$invalid && loginForm.email.$touched">
...
</div>
This trick saved my day.
how do I trigger the error messages without knowing the input name? See the code below:
<input class="form-control"
id="{{field.field_id}}"
set-name="{{field.field_id}}"
type="text"
ng-model="field.field_value"
ng-minlength="field.field_char_num_min"
ng-maxlength="field.field_char_num_max"/>
<div ng-messages="don't know the input name yet" class="my-messages">
<div ng-message="minlength">Your field is too short</div>
<div ng-message="maxlength">Your field is too long</div>
</div>
In ng-messages should be written the path to errors from the input, like myForm.inputName.$error. But the Inputs will be generated and appended automatically so I can't write the name because a generator sets the names. I have to get a hold of the input name. How can I do it?
Try something like this in in ng-message
<form name="formName">
<input type="text" id="anyName" name="anyName" required/>
<span ng-show="formName.anyName.$error.required"> Please enter a value.</span>
</form>
You could use field[field.field_id]['$invalid'] to determine whether field is valid or not, and then by using field[field.field_id]['$error'] show minlength & maxlength error
Markup
<div ng-show="field[field.field_id]['$invalid']" class="my-messages">
<div ng-message="field[field.field_id]['$error'].minlength">Your field is too short</div>
<div ng-message="field[field.field_id]['$error'].maxlength">Your field is too long</div>
</div>
I am trying to submit the form on only successful validation.
validation is working for required but not working for ng-minlength
form input is invalid but form is still being submitted.
<form name="myForm" ng-submit="count = count + 1" ng-init="count=0" ng-app>
<div class="control-group" ng-class="{error: myForm.mobile.$invalid}">
<label class="control-label" for="mobile">Mobile</label>
<div class="controls">
<input type="text" name="mobile" placeholder="07XXXXXXXXX" ng-model="mobile" ng-minlength="11" required />
<span ng-show="myForm.mobile.$error.required" class="help-inline">Required</span>
<span ng-show="myForm.mobile.$error.minlength" class="help-inline">Mobile number should be minimum 11 character starting from 07</span>
</div>
</div>
<div class="control-group">
<div class="controls">
<input class="btn" type="submit" value ="submit" />
</div>
count: {{count}}<br />
<tt>myForm.$invalid = {{myForm.$invalid}}</tt><br/>
</div>
</form>

what am I doing wrong.
I don't want to use submit button disable method.
This is what you are doing wrong: you are mixing two concepts, Angular validators and
HTML5 validators.
The required HTML5 validators, for instance, states that:
When present, it specifies that an input field must be filled out before submitting the form.
So, if you try to submit a form that has an input with this attribute, it will show a message explaining this to the user, and it will prevent the form from being sent. This is the behavior you want. Why isn't working for ng-minlength? Because ng-minlength is an Angular validator (you can tell because it begins with ng-), and it doesn't add any special behavior to the form. It simply set the input where it is located to invalid (and hence, the form), and let you decide what to do with it.
You have an option: you can use the pattern HTML5 validator, to specify the field requires at least 11 characters. It would like this:
<input type="text" pattern=".{11,}">
So when you submit a form containing this input, it will no be sent if the user has enter less than 11 characters.
But since we are it, and you are already using the pattern validator, you could use the regular expression in its full potential, and define something like:
<input type="text" pattern="07[0-9]{9}" />
Which will only admit values of 11 characters, that start by "07" and that contains only digits. I have modified your fiddle to show you how it would work: http://jsfiddle.net/helara/w35SQ/
I mistakenly used ngMaxlength="12" ngMinlength="6" instead of ng-minlength="6" ng-maxlength="12", it's working fine now.
Both ng-minlength & mg-maxlength works in AngularJS.
I've tested this in AngularJS version 1.3.
Make sure to use novalidate with <form> to disable browser's native validation.
This should work:
To enter mobile number
ng-show="myForm.mobile.$touched && myForm.mobile.$error.required"
For minimum length
ng-show="myForm.mobile.$touched && myForm.mobile.$error.minlength"
For maximum length
ng-show="myForm.mobile.$touched && myForm.mobile.$error.maxlength"
This work for me guys
<div class="mdl-textfield mdl-js-textfield mdl-textfield--floating-label">
<input ng-minlength="11" class="mdl-textfield__input" type="text" name="cpf" id="cpf" ng-model="avaliacao.cpf" ng-required="true" ng-pattern="/^\d+$/">
<label class="mdl-textfield__label" for="cpf">CPF *</label>
</div>
<p style="color: #d50000;" ng-show="myForm.cpf.$error.required && myForm.cpf.$dirty">Field Required</p>
<p style="color: #d50000;" ng-show="myForm.cpf.$error.pattern">Only numbers</p>
<p style="color: #d50000;" ng-show="myForm.cpf.$error.minlength">Min 11 Chars</p>
I'm facing the same issue, and I think you can only disable the button or ignore the entered value by yourself. You can also check the $valid property in your controller and ignore the value... It is not so nice, but I found no other way.
I am able to validate my AngularStrap datetimepicker, but I cannot differentiate between a required validation failure and an invalid date failure. The only error that ever shows on screen is the required error, whether it is required or an invalid string. Is it possible in cases where a string has been entered that is invalid to show a different validation message? Here is my code :
<div class="control-group" ng-class="{error: form.BirthDate.$invalid}">
<label class="control-label" for="BirthDate">{{'_BirthDate_' | i18n}}</label>
<div class="controls">
<input id="BirthDate" name="BirthDate" title="BirthDate" type="text" ng-model="user.BirthDate" data-date-format="dd/mm/yyyy" bs-datepicker required>
<span ng-show="form.BirthDate.$dirty && form.BirthDate.$error.required">{{'_BirthDateRequired_' | i18n}}</span>
<!--<span ng-show="form.BirthDate.$dirty && form.BirthDate.$error.pattern">{{'_BirthDateInvalid_' | i18n}}</span>-->
</div>
</div>
What I want is something similar to the ng-pattern check but specific to the datetimepicker.
first of all, I think this has no real link with the date picker or not, if I understand your problem, you are trying to display different messages according to the error that lead to the $invalid for the form
If it's the case, the code you provided will only show a message when the date is invalid (but only because you commented the part for the pattern ;) )
I was super lazy while testing, so I didn't use the datepicker, you'll have to enter a date manually, but I did this fiddle : http://jsfiddle.net/DotDotDot/ELf5A/2/
As I didn't know exactly in what context you were using it, I used different methods to display validation error messages
The HTML part is simple. There is a form, two fields required, one with a pattern check for the date, the other only for the required validation. I added 2 error messages for the date, one displayed when the form hasn't been touched, telling you what format is expected, the other only shows up when the pattern is wrong.
You can click on the button to check the whole validation and then show another message, which will tell you if the form is valid or not, and if not, if it's because of the pattern of the date.
<div ng-controller='theCtrl'>
<form name='theForm'>
Enter something here : <input type='text' ng-model='someField' name='someField' required /> <br/>
Enter a date here : <input type='text' ng-model='theDate' name='theDate' ng-pattern='datePattern' required />
<span ng-show='theForm.theDate.$error.pattern'>Your date format is invalid, please check it again</span>
<span ng-show='theForm.theDate.$pristine'>Enter a valid date here : DD/MM/YYYY</span>
<br/> <input type='button' ng-click='validation(theForm)' value='Try to validate me!' />
<br /> {{errorMsg}}
</form>
</div>
The JS part is not very complicated either. When you click on the button, the form is being sent to the validation function, which will actually do all the checks you want, I only did the one corresponding to the pattern, but you could totally check whatever you want about the validation
$scope.validation=function(aForm){
//console.log(aForm)
if(aForm.theDate.$error.pattern)
$scope.errorMsg='The pattern you entered isn\'t good enough, try again !'
else{
if(aForm.$invalid)
$scope.errorMsg='Something is invalid, please check all the fields !'
else//valid
{
$scope.errorMsg='Not bad !'
alert("good job !")
//maybe you can also submit this form here ;)
}
}
}
This validation function could totally be used as the trigger in a ng-show/ng-hide too, this is why I also added another function :
$scope.whatToDisplay=function(aForm){
if(aForm.$valid)
return 'valid';
if(aForm.theDate.$error.pattern)
return 'date';
if (aForm.$invalid)
return 'notdate';
}
This will return a string corresponding to what is happening during the validation, which will be handled with ng-show :
<span ng-show='whatToDisplay(theForm)=="date"'>Displayed if the date is wrong</span>
<span ng-show='whatToDisplay(theForm)=="notdate"'>This is displayed if the form is invalid, but not because of the date format</span>
<span ng-show='whatToDisplay(theForm)=="valid"'>Displayed if the form is valid</span>
To summarize a bit, you can use 4 different methods
A validation function triggered with a click (useful for submit buttons), corresponding to the validation() function in my fiddle
A function associated with some ng-show, which will automatically watch every change, like the whatToDisplay() function
The ng-show associated with only the form attributes, like what you were doing with your code
The class automatically applied to the form ( I didn't explain it, but you can see it in the fiddle, the border change if the pattern is wrong or if it's only invalid )
Sorry, I had some difficulties to make this short, I let you play with the code, it's easier to understand that way, I hope this will help you
You should use ngMessages in AngularJS 1.3 to do the error messaging with less code and complexity. The bs-angular directive creates a message for the "date" string value of ng-message in your list of messages.
<div class="control-group" ng-class="{error: form.BirthDate.$invalid}">
<label class="control-label" for="BirthDate">
{{'_BirthDate_' | i18n}}
</label>
<div class="controls">
<input id="BirthDate" name="BirthDate" title="BirthDate" type="text"
ng-model="user.BirthDate" data-date-format="dd/mm/yyyy"
bs-datepicker required>
<span ng-show="form.BirthDate.$dirty && form.BirthDate.$error.required">{{'_BirthDateRequired_' | i18n}}</span>
</div>
<div class='alert alert-danger' ng-messages='myForm.BirthDate.$error'
ng-if='!myForm.BirthDate.$valid'>
<div ng-message="date">Please enter a valid date</div>
<div ng-message="required">Birthdate is required</div>
</div>
</div>
This code helps to show the invalid datetime error message
$scope.date=='Invalid Date'
{
err('Your error message');
}
