why ngMessages alert appears only one time?
When I use (data-dismiss="alert" class="close") from the bootstrap options the alert is hide but then it never shows up again.
<body ng-app="ngMessagesExample">
<form name="myForm">
<label>
Enter your name:
<input type="text" name="myName" ng-model="name" ng-minlength="5" ng-maxlength="20" required />
</label>
<pre>myForm.myName.$error = {{ myForm.myName.$error | json }}</pre>
<div ng-messages="myForm.myName.$error">
<div role="alert" class="alert alert-danger alert-dismissible fade in">
<button aria-label="Close" data-dismiss="alert" class="close" type="button">
<span aria-hidden="true">when close never display again -> ×</span>
</button>
<div ng-message="required">You did not enter a field</div>
<div ng-message="minlength">Your field is too short</div>
<div ng-message="maxlength">Your field is too long</div>
</div>
</div>
</form>
</body>

Thanks!
Try this:
<body ng-app="ngMessagesExample">
<form name="myForm">
<label>
Enter your name:
<input type="text" name="myName" ng-model="name" ng-minlength="5" ng-maxlength="20" required />
</label>
<pre>myForm.myName.$error = {{ myForm.myName.$error | json }}</pre>
<div ng-messages="myForm.myName.$error" ng-show="myForm.myName.$touched">
<div ng-message="required">You did not enter a field</div>
<div ng-message="minlength">Your field is too short</div>
<div ng-message="maxlength">Your field is too long</div>
</div>
</form>
</body>
What this will do is show/hide the error message when the user touches the field but does not necessarily make any changes to it. You do not need the button to remove the error message manually as it will be hidden automatically if the user input matches your conditions. You can replace $touched with $pristine or $dirty to trigger the error message based on whether user has not entered anything or has entered something in the field.

I am working on application where I've one form and It should show validation error message for input fields on wrong input.
My form will look like this -
It should show error message if -
Input field modified with wrong input
Submit button clicked without modification in required input field.
It should show error message as below -
To achieve this I am using ng-message directive. It wil help me to show error message on $dirty of input field. But for Submit button I could not find correct way. Currently I am using a flag which will be modified on submit click. But I am interested in some better approach. Is there predefined method available to achieve this ?
Here is the complete example which I tried, and here is plunkr for the same.

app.controller('myCtrl', function($scope) {
$scope.submitForm = function() {
$scope.submitted = true;
if (myForm.$valid) {
alert('Form submitted with passed validation');
}
};
});

You can use $submitted for the form,
Syntax: formname.$submitted
$submitted : True if user has submitted the form even if its invalid.

I could not display the error message while input field takes the invalid data using Angular.js. Here is my code:
<form name="billdata" id="billdata" enctype="multipart/form-data" novalidate>
<div ng-class="{ 'myError': billdata.type.$touched && bill data.type.$invalid }">
<input type="number" class="form-control oditek-form" ng-model="type" name="type" step="1" min="0" placeholder="Add Type" ng-pattern="/^[0-9]+([,.][0-9]+)?$/">
</div>
<div class="help-block" ng-messages="billdata.type.$error" ng-if="billdata.type.$touched">
<p ng-message="pattern" style="color:#F00;">This field needs only number(e.g-0,1..9).</p>
</div>
</form>
Here I need to only give number as input. If user is entering anything rather than number it should display the error message. Here myError is showing the red color border on input field which is coming properly but the message is not coming which should display.
<html>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<div ng-app="">
<form name="myForm">
For Text <input name="myName" ng-model="myName" ng-pattern="/^[a-zA-Z ]+$/" required>
<span style="color: red" ng-show="myForm.myName.$error.required">First Name is required.</span> <span style="color: red" ng-show="myForm.myName.$error.pattern">Any other symbol are not allow.</span>
<br />
For Number
<input type="number" class="textbox_usr" name="txtmobno" id="txtmobno" ng-model="txtmobno" ng-minlength="10" ng-maxlength="10" required /><br />
<span style="color:red" ng-show="myForm.txtmobno.$dirty && myForm.txtmobno.$invalid">
<span ng-show="myForm.txtmobno.$error.required || myForm.txtmobno.$error.number">Valid Mobile number is required</span>
<span ng-show="((myForm.txtmobno.$error.minlength || myForm.txtmobno.$error.maxlength) && myForm.txtmobno.$dirty) ">Mobile number should be 10 digits</span>
</span>
</form>
</div>
ng-messages div should be like following
<div ng-messages="billdata.type.$error" ng-show="billdata.type.$touched">
<div ng-message when="pattern">
<span>This field needs only number(e.g-0,1..9).</span>
</div>

<button>Save</button>
</form>
we can enter the value in number and click add, it will create new textbox with same option (delete,cancel,add). That textbox has some validation
Required
Min and Max range
If i create 4 text-boxes dynamically by clicking add and changing the value of any textbox causes validation failed means , i want to disable the save button which is outside of ng-repeat.
if any textbox failed in validation need to disable the save button.
Can you try the following:
<button ng-disabled="!myForm.$valid">Save</button>
As far as I understand your question this is what you are trying to achieve?
I have used below code for bootstrap textbox and textarea and also in the last div I have used button type="reset" .But when I entered invalid shop name and valid Address and click on Reset button it reset it and after only entering invalid shop name and click on Add shop then it is successfully adding new shop.Both the textbox show green background-color and correct sign even after it is empty.
Please help me.
Please see below image after onclick of reset button:
<form id="defaultForm" method="post" class="form-horizontal"
data-bv-message="This value is not valid"
data-bv-feedbackicons-valid="glyphicon glyphicon-ok"
data-bv-feedbackicons-invalid="glyphicon glyphicon-remove"
data-bv-feedbackicons-validating="glyphicon glyphicon-refresh">
<div class="form-group">
<label class="col-xs-3 control-label">Shop Name</label>
<div class="col-xs-4">
<input type="text" class="form-control" pattern="^[a-zA-Z\s]+$"
data-bv-regexp-message="The shop name can consist of alphabetical characters only" name="shopName" placeholder="Shop Name" data-bv-trigger="blur" data-bv-notempty="true" data-bv-notempty-message="Shop name is required and cannot be empty" />
</div>
</div>
<div class="form-group">
<label class="col-xs-3 control-label">Shop Address</label>
<div class="col-xs-4">
<textarea id="id_txt_addr" type="text" class="form-control" name="shop_address" placeholder="Shop Address" style="height:100px" maxlength="200" data-bv-trigger="blur" data-bv-notempty="true" data-bv-notempty-message="Shop address is required and cannot be empty"></textarea>
</div>
</div>
<div class="form-group">
<div class="col-xs-9 col-xs-offset-3">
<input type="submit" name="add" class="btn btn-primary" value="Add Shop">
<button type="reset" class="btn btn-default">Reset</button>
</div>
</div>
</form>
On reset button click, remove all relevant validation classes and elements handling error message inside closest form. Here an example:
$(':reset').on('click', function(){
var $form = $(this).closest("form");
$form.find('*').removeClass('has-success has-error glyphicon-ok glyphicon-remove');
$form.find('.help-block').remove();
});
-DEMO-
Now maybe there is a bootstrap method to reset validation, you should check bootstrap DOC maybe.
$(document).ready(function () {
$("#ibtReset").on("click", function () {
$('#ShopName').val("");
$('#id_txt_addr').val("");
$('.glyphicon ').remove();
});
});
On reset button click both the values become empty.

I have this form with validation in AngularJS:
<form ng-app="myApp" ng-controller="validateCtrl as validate" name="myForm" action="sendEmail" novalidate>
<div class="form-group">
<input type="email" name="email" class="form-control" ng-model="validate.email" placeholder="Email" required>
<span style="color:yellow" ng-show="myForm.email.$dirty && myForm.email.$invalid">
<span ng-show="myForm.email.$error.required">Email is required.</span>
<span ng-show="myForm.email.$error.email">Invalid email address.</span>
</span>
</div>
<div class="form-group">
<input type="text" name="subject" class="form-control" ng-model="validate.subject" placeholder="Subject" required>
<span style="color:yellow" ng-show="myForm.subject.$dirty && myForm.subject.$invalid">
<span ng-show="myForm.subject.$error.required">Subject is required.</span>
</span>
</div>
<div class="form-group">
<textarea type="text" name="message" class="form-control" ng-model="validate.message" placeholder="Message..." required></textarea>
<span style="color:yellow" ng-show="myForm.message.$dirty && myForm.message.$invalid">
<span ng-show="myForm.message.$error.required">Message is required.</span>
</span>
</div>
<button type="submit" class="btn btn-lg btn-success"
ng-disabled="myForm.email.$dirty && myForm.email.$invalid ||
myForm.subject.$dirty && myForm.subject.$invalid ||
myForm.message.$dirty && myForm.message.$invalid"></button>
</form>
The button is disabled until the email, subject and message aren't correct. Ok, it's fine. But that is true, only if I have already interacted with the form.
In fact, when the page is loaded the first time and I haven't interacted with the form yet, the button is enabled. So, if I click it, I could send an empy email! I would that when the page is loaded the button is disabled and when I fill the fields become enabled.
How can I do that?
Thanks.
You first condition can be ng-disabled=" myForm.email.$invalid . Remove "myForm.email.$dirty
Try like this
<form name="postForm" method="POST" novalidate>
<div class="col-md-8">
<div class="col-md-12">
<div class="col-md-12"><legend>Submit New Post</legend></div>
</div>
<div class="col-md-12 form-group">
<div class="col-md-12" ng-class="{ 'has-error' : postForm.title.$invalid && !postForm.title.$pristine }">
<input type="text" placeholder="Write Title" class="form-control" name="title" ng-model="post.title" required>
<p ng-show="postForm.title.$invalid && !postForm.title.$pristine" class="text-danger">* Write Post Title</p>
</div>
</div>
<div class="col-md-12 form-group">
<div class="col-md-12" ng-class="{ 'has-error' : postForm.url.$invalid && !postForm.url.$pristine }">
<input type="url" placeholder="Write URL" class="form-control" name="url" ng-model="post.url" >
<p ng-show="postForm.url.$invalid && !postForm.url.$pristine" class="text-danger">* Write URL in http:// or https:// Format</p>
</div>
</div>
<div class="col-md-12">
<div class="col-md-12" >
<p class="text-danger">{{msg}}</p>
</div>
</div>
<div class="col-md-12 form-group">
<div class="col-md-12"><button type="submit" class="btn btn-info" ng-disabled="postForm.$invalid" ng-click="submitForm(....)">Submit</button>
<img src="img/loading.gif" ng-show="loading" /></div>
</div>
</div>
</form>
On your submit button, modify the ng-disabled to this:
ng-disabled="myForm.$invalid || myForm.$pristine">
In this case, you don't have to validate all your inputs separetely. Just test if your form is invalid OR if the user never interacted with it yet.
A form in AngularJS has two different states: pristine and dirty. The pristine indicates that your form was never touched. And dirty is the opposite. When the user set any value to one of your inputs, the angular change the state of your form from pristine to dirty.
I guess this post is a good reference to read about forms in angular
