validating minlength and maxlength in md-text-float - angularjs

I want to validate if the user is entering an input between 4-20 characters of length into a md-text-float (angular material directive), with plain angular I would just insert the ng-minlength and ng-maxlength attributes into an tag then validate. But in it doesn't work. How should I validate if the text float holds the required string length and enable the submit button?
<md-text-float label="password" data-ng-model="formPassword"
data-ng-minlength="4" data-ng-maxlength="20" type="password" data-ng-required="true"></md-text-float>
and then enabling.
<md-button class="md-raised md-primary" data-ng-click="submitLogin()" data-ng-disabled="loginForm.$invalid">login</md-button>


Actually For md-text-float directive ng-minlenght and all will not work, validations are still in progress,You can see the link also
https://github.com/angular/material/issues/372
Still, if you want to validate then try to validate it in controller itself to handle validation.


If you want to validate material design inputs, I would suggest using md-input-group directly rather than md-text-float (which uses md-input-group internally), until it supports validation out-of-the-box. I couldn't do a plunker for you, as the site is down - will try to do later on, once the site is back up.
But to give you an idea, the html will look something like this:-
<div class="field" layout="column" layout-align="center center">
<md-input-group>
<label for="email">Email</label>
<md-input type="email" id="email" name="email" required maxlength="50"
ng-model="loginVm.user.email"></md-input>
</md-input-group>
<span class="error-message email-error" ng-if="loginform.$submitted && loginform.email.$invalid">Please enter a valid email address.</span>
</div>

Is it possible to use form attribute in angularjs for form validation?

Please think in angularjs way.
Actually my layout is different.
I have input fields inside form and also have input fields outside form, this is a special case in my product.
I know about form attribute in HTML5
But
In AngualrJS:
I want to achieve outside form input fields works as good as inside form input field works for validation purpose.
Is it possible? We can not remove the place of form tag.
If Yes please guide me.
<div ng-app="myApp" ng-controller="validateCtrl" >
<h6>Validation Example</h6>
<form id="frm" name="myForm" novalidate>
Inside form
<p>
<input type="submit" ng-disabled="myForm.email.$dirty && myForm.email.$invalid">
</p>
</form>
Outside form
<p>Email:<br>
<input form="frm" type="email" name="email" ng-model="email" required>
</p>
</div>

label hiding input text field value in md-input-container when retrieving with ng-value

When using angularjs to retrieve a value for a text input field with ng-value, the label the overlays the field doesn't transition above the field after the value is retrieved. I can only see the value in the input field after clicking on that field.
I'm using material's md-input-container:
<md-input-container>
<label>Name</label>
<input type="text" ng-value="profileInfo.name" ng-model="savedProfileInfo.name" class="provider-name" id="providerName" name="providerName" />
</md-input-container>
Here's the Inspect Element code:
<md-input-container class="">
<label for="providerName">Name</label>
<input type="text" ng-value="profileInfo.name" ng-model="savedProfileInfo.name" class="provider-name ng-pristine ng-untouched ng-valid md-input" id="providerName" name="providerName" aria-invalid="false" value="a"><div class="md-errors-spacer"></div>
</md-input-container>
You can clearly see that value="a" which was pulled after the page loaded using ng-value. But, the field still looks like this:
Only after I click on the field does it look how I would expect:
Is this a bug? Am I missing something? I though AngularJS and Material were supposed to play nice.
Available plunker here

In a roundabout way troig's comment helped me figure this out.
This form is used to display and update a user's profile information. I was using ng-model to update the user's profile and ng-value to display any existing user profile info from the database.
ng-value spits back the value="" attribute which does not play nice with md-input-container. To get this to work properly, I removed ng-value, replaced ng-model's value with profileInfo.name, and modified my controller to allow me to save profileInfo.name instead of savedProfileInfo.name.
Code translation:
<form ng-submit="saveProfile(profileInfo)">
<md-input-container>
<label>Name</label>
<input type="text" ng-model="profileInfo.name" class="provider-name" id="providerName" name="providerName" />
</md-input-container>
Moral of the story, ng-value does not play nice with md-input-container and form labels.

Angular form that contains nested directive not validating

I have a very simplified bit of html like so:
<call-panel>
<form name="hotListForm" >
<twilio>
<input type="text" name="phoneOtherText" id="phoneOtherText" class="form-control" required="required" ng-model="phoneNumber" ng-pattern="validation" ng-trim="false"/>
<span class="error" ng-show="hotListForm.phoneOtherText.$error.pattern">Not a valid phone number</span>
</twilio>
</form>
</call-panel>
But this doesn't work. Is there a special way to do this when in a nested directive. I have verified pattern is available.
Screenshot of it definitely being in the form and of form structure:

It is not working probably because you have the id set to "phoneOtherText" as well, try changing the id and try

angularjs ng-minlength validation is not working, form still being submitted

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.

Is ng-model needed when using ng-disabled and $invalid on a form?

I'm using AngularJS and have a form where I want the Submit button to be disabled if some fields are not filled in.
The standard way seems to be the following:
<form ng-app name="myForm">
<label>Name</label>
<input type="text" name="name" ng-model="form.name" required>
<input type="submit" ng-disabled="myForm.name.$invalid">
</form>
http://jsfiddle.net/YMSRU/
However, if I omit the model from the input field the validation doesn't work and I don't need any models on my input fields (I submit my form using the ngUpload directive so it's actually sent to the form action in an iframe).
Is there any solution or should I add random models just to make the validation work? It seems like a bad work-around.

You could simply do the invalid check at the form level, then no need to define a model for each input:
<form ng-app name="myForm">
<label>Name</label>
<input type="text" name="name" required>
<input type="submit" ng-disabled="myForm.$invalid">
</form>

You are missing your model at your test input tag : ng-model="form.name"
