Here are the code:
I want to get checked radio button value with angularjs click funciton?
<input type="radio" name="calender" value="calender">
<input type="radio" name="calender" value="calender2" checked="checked">
<button ng-click="get_val($event)">Click</button>
$scope.get_val= function(event)
{
}
Here you can add this to get value
var flag_item_val = $("input:radio[name=calender]:checked").val();
Just check out this below code snippet on how to bind values to the ng-model and you can access them anywhere in scope.
var app = angular.module('plunker', []);
app.controller('MainCtrl',
function MainCtrl($scope) {
$scope.radioVal = 'calender2';
$scope.get_val = function(event) {
console.log($scope.radioVal);
}
});
<script data-require="angularjs#1.5.8" data-semver="1.5.8" src="https://opensource.keycdn.com/angularjs/1.5.8/angular.min.js"></script>
<div ng-app="plunker" ng-controller="MainCtrl">
<input type="radio" name="calender" value="calender" ng-model="radioVal">
<input type="radio" name="calender" value="calender2" ng-model="radioVal">
<button ng-click="get_val($event)">Click</button>
</div>

in JavaScript like this :
<!DOCTYPE html>
<html>
<body>
<p>Clear the input field when you click on the button:</p>
<button onclick="document.getElementById('myInput').value = ''">Clear input field</button>
<input type="text" id="myInput">
</body>
</html>
How to use with AngularJS?
You can solve it using ng-model directive, here an example how you can implement it in your code
index.html
<div ng-controller="MainController">
<p>Clear the input field when you click on the button:</p>
<button ng-click="clearInput()">Clear input field</button>
<input type="text" id="myInput" ng-model="input">
</div>
app.js
var myApp = angular.module('myApp',[]);
myApp.controller('MainController', ['$scope', function($scope) {
$scope.input = '';
$scope.clearInput = function() {
$scope.input = '';
}
}]);
You can see the angularjs documentation for more examples.
https://docs.angularjs.org/guide/controller
i succeeded in dom javascript, with inline onclick event
<input type="text" id="hdd_data_2" value="3 TB">
<button type="button" onclick="document.getElementById('hdd_data_2').value ''">Clear</button>
I am using a javascript UI library as DHTMLX or YUI etc.
And I am using AngularJS to process dynamic page.
What I need is just simple.
UI code is
...
<Input type="checkbox" name="XXX" />
....
My.js
...
app.controller('XXXCtrl', function($scope){
$scope.$watch(???){
if (XXX) console.log("checkbox was checked!!!");
else console.log("checkbox was unchecked!!!");
????
};
})
I am new to AngularJS. Please help me!!!
You have to bind the value to the scope via ng-model. There is more detail in the documentation, but you can do something like that:
$scope.checkboxModel = true;
$scope.myAction = function () {
msg = $scope.checkboxModel ? 'checked' : 'unchecked';
console.log(msg);
};
And in your HTML file:
<form name="myForm" ng-controller="XXXCtrl">
<label>Value1:
<input type="checkbox" name="XXX" ng-model="checkboxModel" ng-change="myAction()">
</label><br/>
<tt>value1 = {{checkboxModel}}</tt><br/>
</form>
You can access to the window object using document.getElementById combined with ng-click event listener
var app = angular.module('myApp', []);
app.controller('appCtrl', function($scope) {
$scope.checker= function(e){
var chkBox = document.getElementById(e.target.id);
console.log(chkBox.checked)
}
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app='myApp'>
<div ng-controller='appCtrl'>
<input type="checkbox" id="myCheckbox" name="myCheckbox" ng-click="checker($event)"/>
</div>
</div>
I have a problem to show INPUT field when do some action.
I have BUTTON (Click here) as soon as user made a click event on button i wanted to show input field
I have done this by using jQuery.
Can any one help me in Angular.js
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.boxShow = false;
});
</script>
<div ng-app="myApp">
<div ng-controller="myCtrl">
show box
<div ng-show="boxShow">
<textarea rows="4" cols="50">text</textarea>
</div>
</div>
</div>
https://jsfiddle.net/bxwjpmaa/1/
HTML
<div class="btn btn-primary" ng-click="openTextBox();">Click Me To open text box</div>
<div ng-show="openTextBox == true">
<input type="text"/>
</div>
SCRIPT :
$scope.openTextBox = function () {
$scope.openTextBox = true;
}
please don't take scope variables and function names same
example here
$scope.openTextBox = function () {
$scope.openTextBox = true;
}
//this is not correct as per angular documentation because scope.openTextBox name already assigned to scope function,again its assigning scope variable "$scope.openTextBox = true" here u will get errors when ever u clicked div second time" TypeError: boolean is not a function" it will throw this error.so please dont use which is already assigned scope function dont assign scope variable

I am trying to uncheck checkbox with submit button. The idea is when checkbox is checked button is shown, and when button is clicked checkbox is unchecked and button is hidden.
HTML page:
<html ng-app="myApp" ng-controller="myCtrl">
<head>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.2.15/angular.min.js"></script>
<script src="script.js"></script>
<meta charset=utf-8 />
</head>
<body>
<div ng-repeat="foo in boxes">
<div>
<input type="checkbox" name="cb" id="cb" ng-model="show" />{{foo}}
</div>
<div ng-show="show">
<form ng-submit="submit()">
<input type="submit" name="sumbit" id="sumbit" value="Hide" />
</form>
</div>
</div>
</body>
</html>
JS:
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.boxes = ['a','b','c'];
$scope.submit = function(){
$scope.show = false;
}
});

Thanks for any help!
The problem is that you're using a single variable to store states of 3 items yet Angular creates a scope for each context in the ng-repeat iteration. By changing show to an array and using $index to reference each of them, the show array from the main scope is passed to all three child scopes and there are no conflicts, so it works:
app.controller('myCtrl', function($scope) {
$scope.boxes = ['a','b','c'];
$scope.show = [];
$scope.submit = function(){
$scope.show = [];
}
});
HTML
<div ng-repeat="foo in boxes">
<div>
<input type="checkbox" name="cb" id="cb" ng-model="show[$index]" />{{foo}}
</div>
<div ng-show="show[$index]">
<form ng-submit="submit()">
<input type="submit" name="sumbit" id="sumbit" value="Hide" />
</form>
</div>
</div>
See it here: http://plnkr.co/edit/kfTMaLTXWtpt7N9JVHAQ?p=preview
(note sure if this is exactly what you wanted because there's no question, but it's enough to get you started)
UPDATE
And here is the version where Hide unchecks only "its own" checkbox ($scope.submit now accepts the index parameter): http://plnkr.co/edit/YVICOmQrPeCCUKP2tBBl?p=preview
You need to change the html code and simplify it as
Instead of form use simple ng-click
<div ng-show="show">
<input type="submit" value="Hide" ng-click="show = !show" />
</div>
I want my controller to perform some action when a user clicks in a form field (when the form field gets focus). How can I do this? See this plunker.
Here is my controller:
angular.module('myApp', [])
.controller('AppCtrl', ['$scope',
function($scope) {
$scope.field1 = "Default text";
$scope.focus = false;
$scope.formFieldJustGotFocus = function() {
$scope.focus = true;
// Do all the stuff I need to happen when the form has just gotten focus
}
}
]);
And here is the view:
<body ng-app="myApp" ng-controller="AppCtrl">
<h3>Testing</h3>
<p>I want to perform some action in the controller when a form field gets focus. How can I best achieve this?</p>
<form name="myForm">
<input type="text" name="field1" ng-model="field1">
</form>
<p>Form field has focus: {{focus}}</p>
</body>
You can use the ngFocus directive. The inverse is ngBlur.
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app>
<input type="text" ng-focus="isFocused = true" ng-blur="isFocused = false">
<p ng-if="isFocused">Focus !</p>
</div>
<input type="text" name="field1" ng-model="field1" ng-focus="formFieldJustGotFocus()">
use like this ng-focus
Try ng-focus.
See more info:
https://docs.angularjs.org/api/ng/directive/ngFocus
use -> ng-focus
<input type="text" name="field1" ng-model="field1" ng-focus="formFieldJustGotFocus();">
this plunker
in the code he had written the function formFieldJustGotFocus(), but it was not bound to the focus event
