Validate textarea with Angular ng-messages when using Tinymce (ui-tinymce) - angularjs

How to validate using ng-messages like ng-maxlength when the <textarea> has a ui-tinymce attribute?
Or is there a better way?
<div class="form-group">
<div class="col-sm-12">
<label>Description</label>
<p class="small">Please provide as much detailed information as possible.</p>
<textarea name="description" class="form-control required" ui-tinymce="tinymceOptions" ng-model="aC.testData.description"
ng-maxlength="100" required></textarea>
<div class="help-block" ng-messages="mainForm.description.$error" ng-show="mainForm.description.$touched">
<p ng-message="required">A description is required.</p>
<p ng-message="maxlength">Description must not exceed 100 characters.</p>
</div>
</div>
</div>


The issue you are seeing is that the standard directives just count characters so a simple (empty) HTML sample:
<p></p>
Would indeed show as 7 characters when in reality there is no "visible" content. I built a custom directive for another editor and what I ended up doing is using jQuery's .text() function against the HTML. This removes all of the HTML tags and provides an approximation for the number of actual text characters in the editor. This is a portion of the code in the diective:
var jStrippedString = jQuery(modelValue).text().trim();
return (maxlength < 0) || ngModelCtrl.$isEmpty(jStrippedString) || (jStrippedString.length <= maxlength);
I believe that you would want to create a custom Attribute directive that allows you to grab the model data for the editor and perform this validation yourself.


Adding forced_root_block: "" to the tinymce options should also work. By default it will not add <p></p> from the start.

How can make a label not visible as soon as a user types in an input using AngularJS?

I have a html as follows
<input ng-required="true" ng-model="Email" type="text" value="">
and i have a div as follows:
<div id="invalid" style="display: none">
<strong><i class="mycustomclass" ></i>Invalid</strong>
</div>
How can i make it that as soon as the user types in the input then the div is no longer visible or hidden using Angularjs. I know i need to use ng-show or hide but i cant seem to figure out how to put it together with the input ?

If you are using components it will look like this:
<div id="invalid" data-ng-hide="$ctrl.Email">
<strong><i class="mycustomclass" ></i>Invalid</strong>
</div>
If you are using old controller style:
<div id="invalid" data-ng-hide="Email">
<strong><i class="mycustomclass" ></i>Invalid</strong>
</div>

How to use ng-messages within repeated md-input-container

With Angular 1.5.5 and Angular-Material 1.0.9 I have created a HTML form like this with a repeated input element. I want to use ngMessages for the error messages. The problem I have is that when I enter for example -1, the correct error message is shown in a tooltip, but not below the input element. The issue seems to be that the ng-messages attribute does not support interpolation like the input's name attribute. I could put a variable into the $scope which contains the correct name, but I am not happy with that option because then the input's name is defined in the HTML template and the JavaScript controller. Is there a way to do this more cleanly?
<form name="form">
<md-input-container ng-repeat="product in purchase.products">
<input type="number" min="0" max="9999" ng-model="product.quantity"
name="product[{{$index}}].quantity">
<div ng-messages="form.product[$index].quantity.$error" md-auto-hide="false">
<div ng-message="min">Please enter 0 or more</div>
<div ng-message="max">Please enter 9999 or less</div>
</div>
</md-input-container>
</form>
To be extra clear: In the rendered DOM, there is <input name="product[0].quantity" while ng-messages does not change and $index is not evaluated. I guess I would need an expression that evaluates to "product[0].quantity".

Change your name property to:
<input type="number" min="0" max="9999" required ng-model="product.quantity" name="product_{{$index}}">
And your ngMessages to:
<div ng-messages="form['product_' + $index].$error">
Now it should work.

textAngular validation

I am trying to validate textAngular fileds, I need to add required, max and min characters and border color on red/green on textAngular... I have for each loop and inide textAngulars...
Here is my code:
<form ng-submit="addReply(x)" class="dd animated slideInDown" novalidate>
<div class="form-group">
<text-angular ng-minlength=10 ng-maxlength=600 required ta-text-editor-class="form-control myform1-height" ta-html-editor-class="form-control myform1-height" ta-toolbar="[['bold','italics']]" style="min-height: 100px; color:red;" ng-model="form.reply[x.pivot.comment_id]"></text-angular>
<span ng-show="form.reply[x.pivot.comment_id].$dirty && form.reply[x.pivot.comment_id].$invalid"></span>
<span ng-show="form.reply[x.pivot.comment_id].$error.min || form.reply[x.pivot.comment_id].$error.max">
The value must be in range 0 to 10!</span>
<span ng-show="form.reply[x.pivot.comment_id].$error.required">Email is required.</span>
</div>
<div class="form-group">
<addreply></addreply>
</div>
</form>
My code don't work I don't know why...

According to AngularJS documentation, your form and inputs should have names.
Then you should set validation ng-show's to form_name.input_name.$error and so on, like here

this one is a small example based on your question for
validating the required field

How do I dynamically set element name for form validation?

I have a form with input fields generated with an ng-repeat. The field names are set dynamically from the model. I cannot get validation to work.
Here is the input field that is repeated within ng-repeat:
<input class="form-control input" type="number" id="item.id" name="item.name" ng-change="ctrl.updateSub(item)" ng-model="item.qty" max="item.maxqty" min="0">
I am trying to validate against the max value, which is also set dynamically.
What I cannot find anywhere is how to set the name within the ng-show classes.
<div class="col-sm-2 error" ng-show="form.{{item.name}}.$invalid">
<small class="error" ng-show="form.{{item.name}}.$error.max">
You exceeded the maximum allowed
</small>
</div>
How am I supposed to handle the {{item.name}} bit?
Thanks in advance for any help or pointers.
Angular 1.3.12

Firstly form is a reserved keyword, you cannot use that as your form name.
Coming to your problem, unfortunately as of right now it is not possible to generate dynamic names for form inputs.
You can achieve what you want with the help of ng-form
Have a look at this example :
<form name="yourForm" >
<div ng-repeat="field in fields" ng-form="myInnerForm">
<input type="text" name="dynamic_input" ng-model="field.name"/>
<div ng-show="myInnerForm.dynamic_input.$dirty && myInnerForm.dynamic_input.$invalid">
The field is required.
</div>
</div>
</form>

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.
