I've just started learning AngularJS and one of my first pages requires intercepting a submit. I'd like to use the ng-submit directive but it seems there's something wrong in my code:
<html ng-app>
<head>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.9/angular.min.js"></script>
<script>
function MyFormController($scope) {
scope.add = function(field) {
alert(field);
};
}
</script>
<body>
<div ng-controller="MyFormController">
<form ng-submit="add(field)">
<input type="text" name="field" ng-model="field" />
<input type="submit" value="Submit" />
</form>
</div>
</body>
</html>
I've added an alter to see if the add function is called, yet nothing is displayed. I guess it must be a silly issue, yet I'm unable to catch it. Any help ? Thanks!
You can save the value without the parameter :
<script>
function MyFormController($scope) {
$scope.add = function() {
alert($scope.field);
};
}
</script>
<body>
<div ng-controller="MyFormController">
<form ng-submit="add()">
<input type="text" name="field" ng-model="field" />
<input type="submit" value="Submit" />
</form>
</div>
</body>
Please try this.
<script>
function MyFormController($scope) {
$scope.add = function(field) {
alert($scope.field);
};
}
</script>
<body>
<div ng-controller="MyFormController">
<form ng-submit="add()">
<input type="text" name="field" ng-model="field" />
<input type="submit" value="Submit" />
</form>
</div>
</body>
</html>

I am always getting the alert message from the else part which states form invalid
Form directive is bounded to scope, so you need to write it as $scope.sampleForm.$valid. Since your name is dynamic, you can use a bracket notation: $scope[form].$valid. But either way you need to inject $scope into your controller.
Here is a demo:

You are passing form as a string in ng-click method not a form Object.So u have to pass the form object without Single-cotts.
ng-click="sm.submitForm('sampleForm')" to ng-click="sm.submitForm(sampleForm)"
I'm new to Angular and Ionic and I have problem with getting value of input. I get "undefined". Here is my code:
.controller('myCtrl', function($scope) {
$scope.submit = function () {
console.log($scope.name);
}
}
<form ng-submit="submit()">
<input type="text" ng-model="name">
<button class="button">Send</button>
</form>
try this
<form>
<input type="text" ng-model="name">
<button ng-click="submit()" class="button">Send</button>
</form>
Try this code
<form ng-submit="submit()">
<input type="text" ng-model="FinalData.name" name="name">
<button class="button">Send</button>
</form>
And then in controller
$scope.FinalData={};
$scope.FinalData.name ="dasda";
$scope.submit = function(){
console.log($scope.FinalData.name);
}
Check with this example
angular.module('myApp', []).controller('myCtrl', function($scope) {
$scope.name = 'Hello World!';
});

I'm having some problems trying to keep my parent ngForm status updated; it should be set to "Pristine" when all its children are cleaned and set to "Pristine" them selves... but it seems not happen automatically.
I created a plunk here to better explain the problem: http://plnkr.co/edit/vCX7ltOb8fgl3fkEpvzy?p=preview
<body ng-controller="MainCtrl">
<div ng-form="parentForm1" class="parent-form">
parentForm1.dirty: <b>{{parentForm1.$dirty}}</b>
<form name="childForm1" class="child-form" novalidate>
childForm1.dirty: <b>{{childForm1.$dirty}}</b>
<br/>
<input type="text" ng-model="field1">
<br/>
<button ng-click="reset1()">Clean and setPristine</button>
</form>
<form name="childForm2" class="child-form" novalidate>
childForm2.dirty: <b>{{childForm2.$dirty}}</b>
<br/>
<input type="text" ng-model="field2">
<br/>
<button ng-click="reset2()">Clean and setPristine</button>
</form>
</div>
</body>
Where am I wrong? I found solutions using external modules... I'd like to solve it with less code as possible (perhaps a directive?).

I want to get a value which is entered by the user and after that I want to display it in the browser.
I don't want to set the value using $scope inside the controller.
I tried many times but I was unsuccessful to do it.
Can anybody help me?
Just pass the ng-model in click handler function as a parameter.
<input type="text" name="mail" data-ng-model="mail" data-ng-required="true" class="mymail" placeholder="enter mail id"/>
<input type="submit" value="click" ng-click="click(mail)" />
Show the model value in alert as
$scope.click = function(mail)
{
console.log("mail "+mail);
alert("mail "+mail);
}
I'm seeing weird flickering when mousing over the ng-clip enhanced button. I've got the ng-clip enhanced button being shown/hid when the enclosing div is moused over. As the user moves the mouse over the button, it flickers. I'm assuming it's something to do with event handling between Zeroclipboard and the Angular code?
Here is a Plunker page displaying the issue: http://plnkr.co/4gFy9U
The code from Plunker:

});

I was also having this issue. I fixed by using ng-mouseenter on an outer div instead of using ng-mouseover and ng-mouseleave on an inner div instead of ng-mouseout. No flicker!
So:
<div ng-app="myapp" ng-mouseenter="isHovering = true">
<div class="container" ng-controller="myctrl" ng-mouseleave="isHovering = false">
<div class="page-header">
<h1>ngClip <small>example</small></h1>
</div>
<form>
<div style="background:red;" class="form-group">
<label >Copy #1</label>
<input type="text" class="form-control" placeholder="Enter text to copy" ng-model="copy1">
<button ng-if="isHovering" class="btn btn-default" clip-copy="copy1">Copy!</button>
</div>
<br/><br/><br/>
<textarea class="form-control" rows="3" placeholder="paste here"></textarea>
</form>
</div>
</div>
