I am creating a program which generates a quote every time you press the button 'Generate quote'. I am using this API to get the quotes:

<button id="btn1" type="button" ng-click="test()"> Test</button>
<br>
<label id="label" for="btn" ng-model="label"></label>
</body >
</html>
app.js:
var app= angular.module('myApp',[]);
app.controller('quoteGenerator',['$scope','$http', function ($scope, $http) {
var html="https://thesimpsonsquoteapi.glitch.me/quotes";
$scope.generateQuote=function generateQuote() {
$http.get(html)
.then(function(data) {
$scope.data = data;
console.log($scope.data);
document.getElementById("label").innerHTML=data;
})
}
}])
At the moment in the console log I am getting each object's details like character name, quote etc and on the label I am getting 'object Object'. But how do I retrieve simply the quote and print it onto the label.
In Angular you should not modify the DOM directly. So remove this line:
document.getElementById("label").innerHTML=data;
Instead, change the HTML of the label like so:
<label id="label" for="btn">{{data[0].quote}} - {{data[0].character}}</label>
The data you get is structured object, you need to get into each object in list and each property of it to show value inside template like above.

I am learning AngularJS and trying to understand the $scope part, I was trying to do string combine by creating three variables(ng-model) and see how javascript works with angularJS. Say if I insist on creating three of the ng-model, how do I combine the two strings and put them together in the rstString? I tried to read the $scope elements and the data is there, so what did I miss? Thank you.

I added a button in your example :
<!DOCTYPE html>

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.3.4-build.3588/angular.js"></script>

<h4>combine two string using strong expression</h4>
<div ng-app="myApp" ng-controller="myCtrl">

Second String: <input ng-model="secondString" ng-init="secondString=' world'"/><br><br>
Resulting String:<p style="color:blue;font-weight:bold;" ng-model="rstString" ng-init="rstString='aaa'">{{rstString}}</p>
<button ng-click="concat()">Concat</button>
</div>
<script>
var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
$scope.concat = function() {
$scope.rstString = $scope.firstString +$scope.secondString;
}
});
</script>
</body>
</html>
You can do like this too :
<!DOCTYPE html>
<html>
<head>
<title>angularJS for beginners</title>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.3.4-build.3588/angular.js"></script>
</head>
<body>
<h4>combine two string using strong expression</h4>
<div ng-app="myApp" ng-controller="myCtrl">
First String : <input type="text" ng-model="firstString"/><br><br>
Second String: <input ng-model="secondString"/><br><br>
Resulting String:<p style="color:blue;font-weight:bold;" ng-model="rstString">{{rstString}}</p>
<button ng-click="concat()">Concat</button>
</div>
<script>
var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
$scope.firstString = 'hello ';
$scope.secondString = ' world ';
$scope.rstString = 'aaa';
$scope.concat = function() {
$scope.rstString = $scope.firstString +$scope.secondString;
}
});
</script>
</body>
</html>
you can use ng-change event

I'm trying to trigger a click on a link, but it only runs the ng-click
From MyScript.js:
$timeout(function () {
angular.element(document.querySelector('#cancelButton')).triggerHandler('click');
}, 0);
And from Index.cshtml:
<input class="popupButton" type="button" value="Anuluj" />
I know that the way I did with
<a...><input... /></a>
is wrong,
but the important thing is: how to it to click the link and the ng-click?
I have written a simple program to navigate to the link.
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta charset="utf-8" />
</head>
<body>
<div ng-app="app">
<div ng-controller="ctrl">
Redirect to Click Me!
</div>
</div>
<script src="../lib/angular.js"></script>
<script>
var app = angular.module('app', []);
app.controller('ctrl', function ($scope, $log, $window) {
$scope.redirect = function () {
var url = "http://www.google.com";
$window.location.href = url;
};
});
</script>
</body>
</html>
Is this what you wanted?
I have this button with data="test" when I mouseover the button I want to show the word test in {{Detail}} when I mouse out from the button {{Detail}} should show nothing.
</head>
<body ng-app="">
<button ng-mouseover="Detail = data" data="test" >MouseOver Me</button>
Details: {{Detail}}
</body>
</html>
<button ng-mouseover="Detail = data" ng-mouseleave="Detail=''" ng-init="data='test'" >
i think this code is useful for you
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta charset="utf-8" />
<script src="Scripts/angular.js"></script>
<script>
var app = angular.module('myApp', []);
app.controller('MyCtrl', function ($scope) {
$scope.data="test"
$scope.hoverIn = function () {
this.hoverEdit = true;
};
$scope.hoverOut = function () {
this.hoverEdit = false;
};
})
</script>
</head>
<body ng-app="myApp" ng-controller="MyCtrl" >
<button ng-mouseover="hoverIn()" ng-mouseleave="hoverOut()" title="{{data}}">MouseOver Me</button>
Details: <span ng-show="hoverEdit">{{data}}</span>
</body>
</html>
Trying to do simple thing in AngularJS: form->if you put right word->button appears->u can click and go to a different page;(i didn;t try to put a link to the button since it doesn;t appear even without a link)
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title></title>
<link rel="stylesheet" href="foundation.min.css">
</head>
<body ng-app="myApp">
<div ng-controller="MyCtrl">
<input type="text" ng-model="MyCtrl.pass">
<div class="button" ng-show="kPass">click me</div>
</div>
<script src="angular.js"></script>
<script src="app.js"></script>
</body>
</html>
and the js
angular.module('myApp', [])
.controller('MyCtrl', MyCtrl)
function MyCtrl($scope){
$scope.kPass = false;
$scope.pass = "empty";
$scope.$watch($scope.pass,function(){
if($scope.pass == "parola"){
$scope.kPass = !$scope.kPass;
}
})
};
problem: if i type in parola, the button does not appear
i am new to java script. thanks !
You should first read some angular tutorials, you have totaly wrong access to scope and you are using wrong $watch
angular.module('myApp', [])
.controller('MyCtrl', MyCtrl)
function MyCtrl($scope){
$scope.kPass = false;
$scope.pass = "empty";
$scope.$watch('pass',function(){
if($scope.pass == "parola"){
$scope.kPass = !$scope.Kpass;
}
})
};
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title></title>
<link rel="stylesheet" href="foundation.min.css">
</head>
<body ng-app="myApp" ng-controller="MyCtrl">
<div>
<input type="text" ng-model="pass">
<div class="button" ng-show="kPass">click me</div>
</div>
<script src="angular.js"></script>
<script src="app.js"></script>
</body>
</html>
And next thing, you are overkilling your code. You can inline it in template without any controller function
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title></title>
<link rel="stylesheet" href="foundation.min.css">
</head>
<body ng-app="myApp">
<div >
<input type="text" ng-model="pass">
<div class="button" ng-show="pass == 'parola' ">click me</div>
</div>
<script src="angular.js"></script>
<script src="app.js"></script>
</body>
</html>
angular.module('app',[]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="app">
Please input : 'parola' <input type="text" ng-model="pass">
<button ng-show="pass == 'parola'">Next step</button>
</body>
There are several errors here.
First, the password field is bound to MyCtrl.pass. But you're watching the value of $scope.pass
Second, $scope.$watch expects an angular expression to evaluate as argument, not a value to watch. So watching the string 'MyCtrl.pass' would be the correct thing to do.
Third, you shouldn't use a watch at all. You should just use ng-show="isPasswordValid(pass)"(see below), and return true or false from this function.
Fourth, instead of doing $scope.kPass = ($scope.pass == "parola"), you're inverting the value of $scope.kPass, but only if the value is correct. So if it goes from incorrect to correct, kPass will become true. Then if it becomes incorrect, kPass will stay true. And if it becomes correct again, it will become false.
So, to resume, all you need is
<div ng-controller="MyCtrl">
<input type="text" ng-model="pass">
<div class="button" ng-show="isPasswordValid(pass)">click me</div>
</div>
and
$scope.isPasswordValid = function(password) {
return pass === 'parola';
};
I am newbie to Angular and web development, I have a text input area that needs to be selected (highlighted) when a button is clicked in Angular.
do I need to something like angular.element(document.getElelmentById(txt1)) and do select on it?
Similar to this thread:
Selecting all text in HTML text input when clicked , the question is, is there a rightway/better way to do this in Angular?
I have searched for an answer, closest I could get was this thread: How to set focus on input field? but couldn't successfully convert the suggestions for select().
Here is my jsfiddle in plain js: http://jsfiddle.net/x62ye14y/, a translation to angular would be greatly appreciated.
<!DOCTYPE html>
<html>
<body>
Select your favorite fruit:
<input type="text" id="id123" placeholder="ENTER VALUE">
<p>Click the button to select text in the textbox</p>
<button onclick="myFunction()">Select Txt</button>
<script>
function myFunction() {
document.getElementById("id123").select();
}
</script>
</body>
</html>
Here is the code I have so far,:
<!DOCTYPE html>
<html ng-app="demo">
<head lang="en">
<meta charset="utf-8">
<title>Custom Plunker</title>
</head>
<body>
<div ng-controller="DemoCtrl">
<input type="text" ng-model="content" id="txt1"/>
<button ng-click="selectOnClick()">Select Txt</button>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js">
</script>
<script type="text/javascript">
var mod1 = angular.module('demo', []);
mod1.controller('DemoCtrl', function ($scope) {
$scope.content = 'some text';
});
mod1.directive('selectOnClick', function () {
// Linker function
var element1 = angular.element("txt1");
element1.select();
});
</script>
</body>
</html>

Simple way to do is using click event.
for example
<input type = "text" (click) = "$event.target.select()">
Can you try this:
http://plnkr.co/edit/PzcINVKw6KNBFxlZUgAS?p=preview
<!DOCTYPE html>
<html ng-app="demo">
<head lang="en">
<meta charset="utf-8">
<title>Custom Plunker</title>
</head>
<body>
<div ng-controller="DemoCtrl">
<input type="text" ng-model="content" select-on-click />
<p>Content: {{content}}</p>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script>
<script src="app.js"></script>
</body>
</html>
app:
(function (angular) {
var module = angular.module('demo', []);
module.controller('DemoCtrl', function ($scope) {
$scope.content = 'foobar';
});
module.directive('selectOnClick', function () {
// Linker function
return function (scope, element, attrs) {
element.bind('click', function () {
this.select();
});
};
});
}(angular));
you just need to move the select-on-click to a button
