how to not validate hidden field in ng-click?

when user click on submit button i am validating form, using ng-click i am calling function, in this function i am passing form1.$invalid,based on this variable , i am putting condition, if condition true, validate function will call, here problem is mobile is hidden field, this hidden field also checking validation.how can skip or not validate mobile field hidden status, I tried bellow code.
html
----
<form name="form1" novalidate>
<input ng-show="user" type="text" name="user" ng-model="frm1.user" />
<p ng-show="form1.user.$error.required"><span ng-show="errorMsgShow" ng-required="true">{{requiredMsg}}</span></p>
<input ng-show="mobile" type="text" name="mobile" ng-model="frm1.mobile" />
<p ng-show="form1.mobile.$error.required"><span ng-show="errorMsgShow" ng-required="true">{{requiredMsg}}</span></p>
<button ng-click="SubmitForm(regForm.$invalid);">submit</button>
</form>
Script----
$scope.SubmitForm = function(val){
$scope.user= true;
$scope.mobile = false;
if (if(val ===true){
$scope.validation();
}
}
$scope.validation = function(){
$scope.requiredMsg="input fieldis required";
}

I suggest better approach will be taking the mobile input out of the form when it's unnecessary using ng-if rather than just hide it with ng-show.
Ng-if will make sure the input is not rendered in the DOM tree when the condition is false, therefore, there will be no validation triggered.
You can do some research on differences between ng-if and ng-show to have better understanding about these two directives.

Try ng-if to avoid validation.If you want mobile to skip validation then make ng-if as false using expression.
syntax: ng-if="expression"
go to this link for further info
https://docs.angularjs.org/api/ng/directive/ngIf
for difference between ng-if and ng-hide/ng-show refer the below link
what is the difference between ng-if and ng-show/ng-hide

Some observations :
Instead of using ng-show to hide and show the inputs just use <input type="hidden"... > element for mobile field.
No need to use variable $scope.user and $scope.mobile to hide and show the inputs.
Add the required attribute in the user input field not on mobile input field as you don't want to validate mobile field.
Use SubmitForm(form1.$invalid) instead of SubmitForm(regForm.$invalid) as your form name is form1 not regForm.
DEMO
var myApp = angular.module('myApp',[]);
myApp.controller('MyCtrl', function($scope) {
$scope.SubmitForm = function(val) {
console.log(val);
if(val === true) {
$scope.validation();
}
}
$scope.validation = function() {
$scope.requiredMsg="input fieldis required";
}
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="MyCtrl">
<form name="form1" novalidate>
<input type="text" name="user" ng-model="frm1.user" required/>
<p ng-show="form1.user.$error.required">{{requiredMsg}}</p>
<input type="hidden" name="mobile" ng-model="frm1.mobile" />
<button ng-click="SubmitForm(form1.$invalid);">submit</button>
</form>
</div>

Angular using ng-model in input field get null

I know how to pass a value from a view to a controller using ng-model. In the controller it just gets the value from the view using this code $scope.name = this.ngmodelnameinview.
Is it compulsory to use ng-model in field view?
but my problem now is, I have + button, which when I click the button it will automatically put the value inside input text field.
<button data-ng-click="adultCount = adultCount+1"> + </button>
<input type="text" name="totTicket" value="{{adultCount}}">
see picture below:
but when I add ng-model inside input field, it returns null
<input type="text" name="totTicket" value="{{adultCount}}" ng-model="adultcount">
How to fix this? Thanks!

It is giving null just because you have set a value "adultCount" and in ng-model you had given a different name "adultcount" ('c' is in lower case). By updating ng-model with "adultCount", will solve this issue.

JavaScript is case sensitive:
JavaScript is case-sensitive and uses the Unicode character set.1
Use the same case for the scope variable. Update the input attribute ng-model to match the varible - i.e.:
<input type="text" name="totTicket" value="{{adultCount}}" ng-model="adultcount">
should be:
<input type="text" name="totTicket" value="{{adultCount}}" ng-model="adultCount">
<!-- ^ -->
See this demonstrated in the snippet below:
angular.module('app', [])
.controller('ctrl', function($scope) {
//adultCount could be initialized here
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
<button data-ng-click="adultCount = adultCount+1"> + </button>
totTicket:
<input type="text" name="totTicket" value="{{adultCount}}">
totTicket (adultCount):
<input type="text" name="totTicket" value="{{adultCount}}" ng-model="adultCount">
</div>

Update ng-model of input after input's value changed with jquery unsuccessfully

SITUATION:
This is just an example of what I'm trying to accomplish in a real project, where I get an array of names from a web service, then I locate the inputs with those names, select them and then set their values using jQuery.
PROBLEM:
What I need is to know how to update the ng-model of those fields which I changed their value attribute using jQuery
I have tried these
Update Angular model after setting input value with jQuery
Angular model doesn't update when changing input programmatically
Update HTML input value changes in angular ng-model
...but I haven't had luck with any of those options.
I'm using AngularJS v1.4.8 and jQuery v1.11.1
I have tried setting the input type to hidden and type text with style: display:none but I can't get it working properly.
Here is a demo of what I'm trying to do. This has and input and an span bind with the same ng-model.
When you click the button, it's supposed to change the input value using jQuery and then update the ng-model.
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.8/angular.min.js"></script>
</head>
<body data-ng-app="app">
<div data-ng-controller="myCtrl as ctrl">
<span>Value: {{ctrl.myValue}}</span>
<input name="myId" type="hidden" data-ng-model="ctrl.myValue" />
<button data-ng-click="ctrl.changeValue('ValueChanged')">Change Value</button>
</div>
<script>
//my controller
angular.module('app', [])
.controller('myCtrl', function(){
var vm = this;
vm.wizard = {
changeValue: fnChangeValue
}
return vm.wizard;
function fnChangeValue(newValue){
var e = $('#myId');
e.val(newValue);
e.trigger('input'); //first option
//e.triggerHandler('change'); //second option
}
});
</script>
</body>
</html>

Fixed ID and added jQuery's change() which is probably what you tried to do. Below you can find your code fixed. And here is how this is usually done with AngularJS alone: https://jsfiddle.net/rwtm1uh9/
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.8/angular.min.js"></script>
<div data-ng-app="app">
<div data-ng-controller="myCtrl as ctrl">
<span>Value: {{ctrl.myValue}}</span>
<input id="myId" data-ng-model="ctrl.myValue" />
<button data-ng-click="ctrl.changeValue('ValueChanged')">Change Value</button>
</div>
<script>
//my controller
angular.module('app', [])
.controller('myCtrl', function() {
var vm = this;
vm.wizard = {
changeValue: fnChangeValue
}
return vm.wizard;
function fnChangeValue(newValue) {
var e = $('#myId');
e.val(newValue);
e.change();
}
});
</script>
</div>

You write var e = $('#myId'); and inside your input there is
<input name="myId" type="hidden" data-ng-model="ctrl.myValue2" />
I think you missed the id attribute try this instead :
<input id="myId" type="hidden" data-ng-model="ctrl.myValue2" />

AngularJS: Target a form with Controller As syntax in an object

Note: I did look around here on SO for solutions, yet no one had the additional issue of the function being in an object.
I have a form in my Angular JS app:
<div ng-app="plunker">
<div ng-controller="PMTController as pmt">
<form name="myForm">
<div class="form-group">
<input type="text" class="form-control" />
</div>
<button class="btn btn-primary" ng-click="pmt.search.resetSearchForm()">Reset</button>
</form>
</div>
</div>
Further, I have a controller with an object:
app.controller('PMTController', function($log) {
var _this = this;
_this.search = {
resetSearchForm: function () {
$log.debug('test');
// how to target the form?
}
};
})
My ng-click works, as the log.debug works. But no amount of tweaking to target the form so that I can reset the entire thing (empty all the fields) works.
I can do $window.myForm.reset(); but how could I do this from angular?
Note please my main issue/question is how to correctly target the form from inside that resetSearchForm function in the search object.
Note I tried changing the form name to pmt.myForm or pmt.search.myForm to no avail.
I tried $setPristine and $setUntouched() but they don't seem to clear the fields.
I know I can assign a model and assign it to all the form controls, but this is for a prototype so I'd rather do a simple reset.
I made a pen: https://codepen.io/smlombardi/pen/YWOPPq?editors=1011#0

Here is my take on your codepen that will hopefully resolve the issue:
https://codepen.io/watsoncn/pen/YWOXqZ?editors=1011
Explanation:
Angular's documentation provides an example of a "Form Reset" button, but you can apply the same logic towards resetting after submission:
Documentation:https://docs.angularjs.org/guide/forms
with a plunker:
Live Example:https://plnkr.co/edit/?p=preview
The example shows the use of Angular's copy method that creates a deep copy of whatever you pass it as a parameter and assigns it to the ng-model that is put on a particular input field. In this case they simply pass it an empty master object.
You need to make sure to add an ng-model attribute to your inputs, then create a reset function that can run after submission. Another common option would be to simply set each input's ng-model to empty strings in the submission function, such as $scope.inputModel = ""
Is this what you were hoping for? I might have misunderstood the question. I will happily take another crack at it if there is still confusion.

To get the form in your controller you just need to name your form this way:
<form name="pmt.myForm">
Here's a complete demo:
(function() {
"use strict";
angular
.module('plunker', [])
.controller('PMTController', PMTController);
PMTController.$inject = ['$log'];
function PMTController($log) {
var _this = this;
_this.model = {};
_this.search = {
resetSearchForm: function() {
console.log(_this.myForm); // -> Form reference
_this.model = {};
}
};
}
})();

<hr> All fields:

Angularjs keep the focus on a field after ng-click?

I try to figure out how I can keep the focus on an input field in angularjs after I click on a button.
My goal is to prevent my mobile to hide his keyboard right after I click on the + button. I want to keep the focus on input choice.
Like this the user can add a new choice without the need to click again on my input.
<div id="demo" ng-app="Foobar">
<div ng-controller="DemoCtrl">
<input type="text" ng-model="title" placeholder="title" />
<input type="text" ng-model="choice" placeholder="choice" />
<button ng-click="addChoice(choice)">+</button>
{{choices}}
</div>
</div>
angular.module('Foobar', [])
.controller('DemoCtrl', ['$scope', function ($scope) {
$scope.choices = [];
$scope.addChoice = function (choice) {
$scope.choices.push(choice);
};
}]);
http://jsfiddle.net/gbg09bto/
What is the best strategy ? (directive, ng-focus)

simplest thing is do it by plain javascript
to do it
in html // put a id attribute
<input type="text" id="choice" ng-model="choice" placeholder="choice" />
in controller function
$scope.addChoice = function (choice) {
$scope.choices.push(choice);
document.getElementById("choice").focus(); // get the element by id & focus the input
};
here is the updated Fiddle
