How to reset all Models on click event?

My requirement: Have to reset my select boxes on button click
Example :-
I have 3 select boxes. When I click on the select box some different data will come and after that the result will get published. I added a Remove button which resets only its parent select box. Now, what I want to know is,how to reset all the three select box on clicking the remove button.
sample code is as under :-
<button ng-click="removeObj(key,model1,0)">Remove</span></button>
controller code is as under :-
scope.removeObj = function(modelID, subModelID, selectBoxPos) {
modelID = 0;
subModelID = 0;
})
I want on click of removeObj function all modelID data get reset to zero.
Please help.

As I understand you do not need any parameters.. only create a meaningful name resetModels:
AngularJS Controller:
$scope.resetModels = function() {
// Set default value to your models...
$scope.modelID = 0;
$scope.subModelID = 0;
});
Html:
<button ng-click="resetScpeModels()">Remove</span></button>

If you want to reset all the values. You should use it like this
$scope.model = {};
$scope.model.modelID = 0;
$scope.model.subModelID = 0;
<input ng-model="model.modelID"/>
If you want to reset it. Call again
$scope.model = {};
Inside ng-click function.

When you give a name to your form it automatically gets added to the $scope.
In angular we are having a $setPristine() method on the $scope.formName. which should recursively take care of resetting your form.
You can reset a form by, $scope.formName.$setPristine(); but if you're binding a model object to your inputs, you need to take care of clearing those too, ie:
$scope.formModel={}; or angular.copy({}, formModel);
Working demo :
var app = angular.module('myApp', []);
app.controller('myController', function($scope) {
$scope.Reset = function(formModel) {
angular.copy({}, formModel);
$scope.formModel = {};
$scope.submitForm.$setPristine();
}
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp">
<form name="submitForm" ng-controller="myController">
<label for="first_field">First Model</label>
<input ng-model="formModel.firstModel" />
<br />
<label for="second_field">Second Model</label>
<input ng-model="formModel.secondModel" />
<br />
<button type="button" ng-click="Reset(formModel)">Reset</button>
</form>
</div>

reset form value/object to empty upon ng-click in AngularJS

Description:
I'm using ui-router to load form pages upon icon click, whenever the user clicks the icon the new form should load ( remove any filled fields ). I have added ng-click on icon which can be leveraged to reset the form values.
index.html
<td>
<a ui-sref="form2"
title="yahoo">
<span class="glyphicon glyphicon-file" ng-click="newForm('new')" id="yahooIcon" ></span>
</a>
</td>
form2.html
<input type="text" name="firstname" ng-model="myModel.firstname"><br>
app.js
$scope.newForm = function (id){
if ( id == 'new' )
{
console.log(" model value inside: "+$scope.myModel.firstname);
$scope.myModel = {};
}
}
Problem:
ng-model data is showing undefined in controller and not able to reset the model upon clicking the icon.
The demo uses the same controller, However if my from has different controllers than index page. How can i send button click (ng-click) value to child controllers ?
DEMO ( Plunker )

Please Try This
//In Html Page
<button type="reset" ng-click="resetForm(formObject)">Clear Form</button>
//In Angular
$scope.resetForm = function(form) {
angular.copy({},form);
}

My data binding works but my input ng-model isn't updating when I $update

If I do this {{newStore1}} and $scope.newStore1 = 'Owl Store';, when the page loads, the text says Owl Store. That data binding's all good. If I make an input box and give it the model newStoreName, that works too, for the most part...
{{newStore1}}
<form data-ng-submit="storeUpdate()">
<input type="text" ng-model="newStore1">
<input type="submit" />
</form>
The new store name shows as null. Even though as I type in the text box, the {{newStore}} updates with the text. but when I do this, it gives me a null value.
$scope.storeUpdate = function(){
Users.get({email:$scope.global.user.email}, function(user3) {
user3[0].store.push($scope.newStore1); // $scope.newStore1 is working in html but is 'null' here
user3[0].$update(function(response) {
Users.query({}, function(users) {
$scope.users = users;
$scope.global.user = response;
});
});
});
};

in your controller define:
$scope.store = {};
or if you do not want to declare it in your controller, in your HTML you need to declare the model at high level like:
<div ng-model="store.name">
{{store.name}}
<form data-ng-submit="storeUpdate()">
<input type="text" ng-model="store.name">
<input type="submit" />
</form>
<div>

Pass Model to Controller to Change in Controller

Here is my situation, I have this HTML:
<input type="text" ng-model="inputModel" />
<div class="button-container">
<button type="button" ng-click="setValue(inputModel)"></button>
</div>
<input type="text" ng-model="inputModelTwo" />
<div class="button-container">
<button type="button" ng-click="setValue(inputModelTwo)"></button>
</div>
And my view controller:
$scope.setValue = function (valueToSet) {
valueToSet = "Some value.";
};
I need to be able to "connect" the input fields and their buttons and I'm doing this by having the respective button pass the respective input field's model to the controller to be modified. The problem is that when I click the button the function fires off and valueToSet is changed but the change isn't reflected back in the view! What am I missing?

If you are trying to dynamically pass in your models as a function parameter, you'll need to access a PROPERTY on the models by using dot notation.
Try defining the models in the controller like so:
$scope.inputModel = {};
$scope.inputModelTwo = {};
$scope.inputModel.text = 'hey';
$scope.inputModelTwo.text = 'ho';
Then pass in the entire model to the function as you were already doing.
Inside the function, alter the property that you desire (in this case 'text'), like so:
$scope.setValue = function (valueToSet) {
console.log(valueToSet);
valueToSet.text = "Some value.";
};

Simulating a submit and validation to a separate form on AngularJS

How to simulate submit plus validation on a form whose button is outside of it?
It can be done with this:
HTML:
<div ng-controller="MyCtrl">
<form ng-submit="onSubmitted()">
Header inputs:
<input type="name" ng-model="sample" required/>
<input type="name" ng-model="sampleX" required/>
<div style="visibility: hidden">
<input type="submit" id="clcikMe" value="This submit triggers validation. But I wanted to put this button at the end of the page"/>
</div>
</form>
<hr/>
Some other form here. Think line items
<hr />
<a class="btn" linked="clcikMe">Wanted this submit button to trigger the validation+submit on the form in which this button doesn't belong</a>
</div>
Javascript:
var app = angular.module('myApp', []);
function MyCtrl($scope) {
$scope.onSubmitted = function() {
alert('submitted!');
};
}
app.directive("linked",function(){
return function (scope, element, attrs) {
var id = attrs["linked"];
element.on("click",function(){
document.getElementById(id).click();
});
};
});
But I wanted to stay away from that approach, it's very kludgy, it triggers a validation+submit by simulating a submit on first form by clicking its hidden submit button
Is there an API on AngularJS (or even plain javascript) that will let me achieve my objective? I.e. without using any hidden submit button

You're not thinking very Angular here. No one is forcing you to work with form ng-submit. Just use 2 buttons each with their own ng-click="runThisFunction()" or simply use the same function and pass along a parameter. i.e:
<button ng-click="submitForm(true)">Validate + Submit</button>
and
<button ng-click="submitForm(false)">Only Validate</button>
Then in your controller:
$scope.submitForm = function(shouldSubmit) {
//run validation here.
//either using $scope.form.name.$valid or ng-model $scope variable
var dataGood = false;
if ($scope.sample === "goodData" && $scope.sample === "alsoGoodData" ) {
//data is good
dataGood = true;
//alert user that data is good!
alert('good job, your data is great!');
}
else {
//data is bad
alert (' data bad, dear padowan');
}
if (!shouldSubmit) return;
//perform $http request to server, or navigate to a different page or whatever
if (dataGood) {
//submit data to server and let the party begin
$http.post('/api/rocknroll/submit', { sample: $scope.sample, sampleX: $scope.sampleX}).then( $scope.handleResponse);
}
}
This will work whether or not you're in the scope of the form, but you need to be in the scope of the controller.
