I am new to angularjs.
I have 2 buttons on my form and one is Save and other is Test Connection button.
<td align="left" colspan="0" >
<input class="form-control" title="Specifies the IP address of the SIP trunk ethernet connection." placeholder="xxx.xxx.xxx.xxx"
style="display: inline-block;display:block;white-space: nowrap;overflow: hidden;" type="text"
name="pabxipaddress" id="pabxipaddress" ng-model="userSetup.pabxipaddress" required ng-pattern='patternPresent' >
</td>
<td>
<span class="error" ng-show="(testIPOfficeFlag || submitted) && userSetupForm.pabxipaddress.$error.required">
<label style="color: red;">Required!</label>
</span>
<span class="error" ng-show='(testIPOfficeFlag || submitted) && userSetupForm.pabxipaddress.$error.pattern'>
<label style="color: red;">Invalid IP Address!</label>
</span>
</td>
Now in my JS file when I do like,
$scope.userSetup.pabxipaddress.$valid for some dynamic testing it gives me
TypeError: Cannot read property '$valid' of undefined
when I alert like $scope.userSetup.pabxipaddress it displays the data correctly.
How to check whether individual field is correct and passed all constraints attached to it.
The valid property is not part of the model value... try
$scope.userSetupForm.postdail.$valid
where userSetupForm is the name of the form and postdail is the name of the input element.
var app = angular.module('my-app', [], function() {
})
app.controller('AppController', function($scope) {
$scope.check = function() {
$scope.validity = {
field1: $scope.myform.myfield1.$valid,
field2: $scope.myform.myfield2.$valid,
field3: $scope.myform.myfield3.$valid
}
};
})

1st of all you need to give your form a name here its signupForm .
2nd from there you need to give your input fields names for example here they areusername and email.
Then you can use various angular validation directives to set validation constrains like require , length then you can check for validation error using signupForm.username.$invalid and check various error like signupForm.email.$error.email.
Finally if you want to check if the whole from is valid use signupForm.$invalid
and for number validation use
angular.module('test')
.directive('validNumber', function() {
return {
require: '?ngModel',
link: function(scope, element, attrs, ngModelCtrl) {
if(!ngModelCtrl) {
return;
}
ngModelCtrl.$parsers.push(function(val) {
if (angular.isUndefined(val)) {
val = '';
}
var clean = val.replace( /[^0-9\.]/g, '');
if (val !== clean) {
ngModelCtrl.$setViewValue(clean);
ngModelCtrl.$render();
}
return clean;
});
element.bind('keypress', function(event) {
if(event.keyCode === 32) {
event.preventDefault();
}
});
}
};
});

In order to disable the submit button, you can do something like this:
<form name="myForm">
<input ...>
...
<button type="button" ng-disabled="myForm.$invalid" ng-click="formsubmit();">
Submit
</button>
</form>
Notice that I have put ng-disabled with a condition of myForm being invalid. So, instead of waiting for user to click the button, we are disabling the submit button upfront when form is invalid!
For Email validation, I would suggest you to go with <input type = "email"...> unless you have specific email validation requirements not handled by type = "email"
Here's the updated fiddle which disables the submit button until we put a valid email address.
Edit: Here's an example of how ng-pattern can be used to validate email for given rules (i.e. email must contain #, dot and after dot minimum 2 & maximum 4 alphabet characters)
<input type="text" ng-model="user.email" name="email" required
ng-pattern="/[a-zA-Z0-9_.]+\#[a-zA-Z0-9_]+\.[a-zA-Z]{2,4}$/"/>
Here's the updated fiddle

I want to retain the selected check boxes as is even when I am
changing my search query. Initially I am posting some query in search
and selecting one of the resulted values, Now if I change my search
query, then New values will be my result. But I want to retain the
checkbox selected for the previous values...

Try to add ng-model="item.selected" to your checkbox tag
<td><input ng-model="item.selected" type="checkbox" name="test" />{{item.EmpId}}</td>
Works for me, hope it helps.
Looks like this is happening because you are resetting the items here:
if($scope.searchText == '')
{
$scope.filteredList = $scope.allItems ;
}
and allItems doesn't tell anywhere if the checkbox needs to be selected on not. I would suggest you to update the code where you are creating the checkboxes, something like:
<td><input type="checkbox" name="test" ng-model=item.selected ng-checked=item.selected/>
Note that I have updated the item to have a 'selected' field which will tell if that item is selected or not(default could be false). While creating the checkbox I have linked the model using ng-model=item.selected

i'm trying to do a form with validations using angularjs and so far i did a good job. But when i commit my reset button all the fields reset except for the error messages i get from my validation part. How can i get rid of all the fields and error messages when i reset my form.

$scope.reset = function() {
var original = $scope.user;
$scope.user= angular.copy(original)
$scope.userForm.$setPristine()
};
})
var original = $scope.user;
when resetting :
$scope.user= angular.copy(original);
$scope.userForm.$setPristine();
remove
type='reset' in <button>
here is the Angular Documentation for form controllers.
Use the following to reset dirty state
$scope.form.$setPristine();
Use the following to reset to clear validation
$scope.form.$setValidity();
There's API documentation on the FormController.
This allowed me to find that there's other methods to call such as:
$setUntouched() - which is a function I was using if the user has focused on the field, and then left the field, this clears this feature when you run it.
I created a simple form reset function which you can use too.
// Set the following in your controller for the form/page.
// Allows you to set default form values on fields.
$scope.defaultFormData = { username : 'Bob'}
// Save a copy of the defaultFormData
$scope.resetCopy = angular.copy($scope.defaultFormData);
// Create a method to reset the form back to it's original state.
$scope.resetForm = function() {
// Set the field values back to the original default values
$scope.defaultFormData = angular.copy($scope.resetCopy);
$scope.myForm.$setPristine();
$scope.myForm.$setValidity();
$scope.myForm.$setUntouched();
// in my case I had to call $apply to refresh the page, you may also need this.
$scope.$apply();
}
In your form, this simple setup will allow you to reset the form
<form ng-submit="doSomethingOnSubmit()" name="myForm">
<input type="text" name="username" ng-model="username" ng-required />
<input type="password" name="password" ng-model="password" ng-required />
<button type="button" ng-click="resetForm()">Reset</button>
<button type="submit">Log In</button>
</form>
I went with...
$scope.form.$setPristine();
$scope.form.$error = {};
Feels hacky... but a lot about angular does.
Besides... this was the only thing that worked.
I had the same problem and used the following code to completely reset the form :
$scope.resetForm = function(){
// reset your model data
$scope.user = ...
// reset all errors
for (var att in $scope.userForm.$error) {
if ($scope.userForm.$error.hasOwnProperty(att)) {
$scope.userForm.$setValidity(att, true);
}
}
// reset validation's state
$scope.userForm.$setPristine(true);
};
To me using $setPristine to reset the form is a hack.
The real solution is to keep it like it should be:
<button type="reset" ng-click="reset()"></button>
then in angular:
var original = angular.copy($scope.user);
$scope.reset = function() {
$scope.user = angular.copy(original);
};
and that's it.
Use this
<button type="button" ng-click='resetForm()'>Reset</button>
In Controller
$scope.resetForm = function(){
$scope.userForm.$dirty = false;
$scope.userForm.$pristine = true;
$scope.userForm.$submitted = false;
};
Its working for me
In case you don't have a master (dynamic models from server), and you want to reset the form but only the binded part of the model you can use this snippet:
function resetForm(form){
_.forEach(form, function(elem){
if(elem !== undefined && elem.$modelValue !== undefined){
elem.$viewValue = null;
elem.$commitViewValue();
}
});
}
And then you can use it with a standard reset button like so:
<button type="reset" ng-click="resetForm(MyForm);MyForm.$setValidity();">reset</button>
Give us your Feedback
<!-- pass in the variable if our form is valid or invalid -->
<form name="userForm" ng-submit="submitForm(userForm.$valid)" novalidate>
<!-- NAME -->
<div class="form-group" ng-class="{ 'has-error' : userForm.name.$invalid && !userForm.name.$dirty }">

<p ng-show="userForm.email.$invalid && !userForm.email.$pristine" class="help-block"><font color="#009ACD">Enter a valid email.</font></p>

<!-- USERNAME -->
<div class="form-group" ng-class="{ 'has-error' : userForm.username.$invalid && !userForm.username.$dirty }">

<font color="white"><p ng-show="userForm.username.$error.minlength" class="help-block"><font color="#009ACD">Description is too short.</font></p>

I kept the type="reset" in my button. What I did was the ng-click="resetForm(userForm)" (using userFrom to match your example) and the controller defines resetForm() as
scope.resetForm = function(controller) {
controller.$commitViewValue();
controller.$setPristine();
};
Here is what happens:
When the reset button is clicked, it will bring back the original values as specified by the value attribute on the input
The $commitViewValue() will force the write of whatever is on the view presently to the $modelValue of each field (no need to iterate manually), without this the last $modelValue would still be stored rather than reset.
The $setPristine() will reset any other validation and submitted fields.
In my angular-bootstrap-validator I already had the FormController as such I didn't need to pass in the form itself.
In My Form
<form angular-validator-submit="submitReview()" name="formReview" novalidate angular-validator>
<input type="text" name="Rating" validate-on="Rating" class="form-control"
ng-model="Review.Rating" required-message="'Enter Rating'" required>
<button type="button" ng-click="reset()">Cancel</button>
</form>
app.controller('AddReview', function ($scope) {
$scope.reset= function () {
$scope.formReview.reset()
};
});
only need to call $scope.formReview.reset() where formReview is my form name.
My form is inside another scope so my solution need to use $$postDigest
$scope.$$postDigest(function() {
$scope.form.$error = {};
});
To reset the validations we have to do two things:
clear the fields
Add the following:
$scope.programCreateFrm.$dirty = false;
$scope.programCreateFrm.$pristine = true;
$scope.programCreateFrm.$submitted = false;
programCreateFrm is the name of the form.
For example:
<form name="programCreateFrm" ng-submit="programCreateFrm.$valid && createProgram(programs)" novalidate>
This code is working for me.
Im trying to post input data with angular, but I don't know how to grab the data from the input fields.
Here is my HTML:
<div ng-controller="Test">
<div class="container">
<div class="col-sm-9 col-sm-offset-2">
<div class="page-header"><h1>Testar</h1></div>
<form name="userForm" ng-submit="submitForm(userForm.$valid)" novalidate> <!-- novalidate prevents HTML5 validation since we will be validating ourselves -->
<div class="form-group" ng-class="{'has-error' : userForm.name.$invalid && !userForm.name.$pristine, 'has-success' : userForm.name.$valid }">
<label>Name</label>
<input type="text" name="name" class="form-control" ng-model="name" required>
<p ng-show="userForm.name.$invalid && !userForm.name.$pristine" class="help-block">Fel namn</p>
</div>
<div class="form-group" ng-class="{'has-error' : userForm.username.$invalid && !userForm.username.$pristine, 'has-success' : userForm.username.$valid && !userForm.username.$pristine}">
<label>Username</label>
<input type="text" name="username" class="form-control" ng-model="user.username" ng-minlength="3" ng-maxlength="8">
<p ng-show="userForm.username.$error.minlength" class="help-block">För kort</p>
<p ng-show="userForm.username.$error.maxlength" class="help-block">För långt</p>
</div>
<div class="form-group" ng-class="{'has-error' : userForm.email.$invalid && !userForm.email.$pristine, 'has-success' : userForm.email.$valid && !userForm.email.$pristine}">
<label>Email</label>
<input type="email" name="email" class="form-control" ng-model="email">
<p ng-show="userForm.email.$invalid && !userForm.email.$pristine" class="help-block">Ange korrekt e-post</p>
</div>
<button type="submit" class="btn btn-primary">Lägg till</button>
</form>
</div>
</div>
</div>
Here is my controller:
as.controller('Test', function($scope, $http, $rootScope)
{
$scope.submitForm = function(isValid) {
if(isValid)
{
$http.post($rootScope.appUrl + '/nao/test', {"data": $scope.userForm})
.success(function(data, status, headers, config) {
console.log(data);
}).error(function(data, status) {
});
}
};
});
A post is made when I hit the button, but the data that Is being sent looks like this:
{"data":{"name":{},"username":{},"email":{}}}
How can I take the data from all the input fields? Should I refer to userForm as I do in the controller?
I suggest to create one more $scope object - at beginning it will be empty:
$scope.form = {};
Every field will be a part of this object:
<input type="text" name="name" class="form-control" ng-model="form.name" required>
After send all fields you will have in object $scope.form.
jsFiddle: http://jsfiddle.net/krzysztof_safjanowski/QjNd6/
you have ng-model variables in scope:
$scope.name
$scope.user.username
$scope.email
you can all of these prefix with user. and then send with ajax $scope.user instead of $scope.userForm
or
try to send object which is copied by: angular.copy($scope.userForm)
You can have a property in your scope, say user. Have all your ng-model values be user.SOMETHING. This way you can easily send the $scope.user holding all the data, as in {data: $scope.user }.
I have two fields , for email the validation is working fine , but for radio button no error is been shown .. i am not getting this , why this is happening . i ma using angular-1.0.8.min.js
//js code
var app = angular.module("App", []);
app.controller('signupController', ['$scope', function($scope) {
$scope.selectedGender = '';
$scope.gender = [{'name':'Male', 'id':1}, {'name':'Female', 'id':2}];
$scope.submitted = true;
$scope.signupForm = function() {
if ($scope.signup_form.$valid) {
// Submit as normal
} else {
$scope.signup_form.submitted = true;
}
}
}]);
//html code

It's hard to tell for sure because the code provided is invalid but you are probably hitting the angular js bug where it doesn't mark the radio button as valid until all radio buttons have been selected.
See this question
This is fixed in version 1.2.0-rc.3. I've created a Plunker demo here with some code changes to mimic what I think you are trying to do.
