Here is my html code
<div ng-app='app'>
<div ng-controller="MyController" ng-init="myVar=7">
{{myVar}}
<span ng-init="myVar=myVar+5">{{myVar}},</span>
<span ng-init="myVar=myVar+15">{{myVar}},</span>
<span ng-init="myVar=myVar+37">{{myVar}},</span>
</div>
and script
var app = angular.module('app',[]);
app.controller('MyController', function() {});
The output I'm getting is 64,64,64,64
but I want output as 7,12,27,64
I'm trying to find things like ng-repeat but I cant kept these in an array
In every ng-init you're altering the value of myVar that is data bound to all other instances; and that's why they all show the same. So rather do:
<div ng-app='app'>
<div ng-controller="MyController" ng-init="myVar=7">
{{myVar}}
<span>{{myVar+5}},</span>
<span>{{myVar+15}},</span>
<span>{{myVar+37}},</span>
</div>

I want to display some data and tables in the content div which depends on which category you choose on the left hand side navigation.
So if I change the category also the displayed content of the content div should change.
Here is my code on Plunkr.
But it seems that not even this simple example is working.
So I have two Questions:
1.) How can I fix this example code to run ?
But more important:
2.) Is there a better way to change the content div when you change the category ?
I removed 'this' elements from code and also changed ng-view to ng-show.
<div>
<div ng-show="showApple">{{content}}</div>
<div ng-show="showBanana">{{content}}</div>
<div ng-show="showOrange">{{content}}</div>
</div>
There was something wrong with that you named your div class "content" so I removed that also.
I am sure it isn't a perfect solution but now it works.
link to plnkr
To be honest your best bet is to use $states/views. With a data-ui-view on the content div and a data-ui-sref link on the button on your menu, you can easily switch out content. Take a look at the ui-router page to get a better understanding of it. With templates for each 'view' that your menu will click to, your code will not just be much easier to manage, but probably more understandable.
You can use ng-include to show your contents but you have to keep them in seperate files e.g contentForApple, contentForBanana and contentForOrange.
Here I can show you a little change in your div
<div class="content">
<div ng-show="MainCtrl.showApple" ng-include ="'contentForApple.html'"></div>
<div ng-show="MainCtrl.showBanana" ng-include = "'contentForBanana.html'"></div>
<div ng-show="MainCtrl.showOrange" ng-include = "'contentForOrange.html'"></div>
</div>
Hope this help you. Take one json array for category and data and get details of json data which index is clicked

$scope.getData = function(index)
{
$scope.data = $scope.category[index]['data'];
}
});
</script>

</html>
I did it with simple ngif
1) Keep an Index of Page which needs to be is loaded now
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.name = 'World';
$scope.pageIndex = 0;
/*
* Updates current Page index
*/
$scope.changeIndex= function(indexToChange){
$scope.pageIndex = indexToChange;
}
});
2) Load content based on selected index
<body ng-controller="MainCtrl">
<div class="mainframe">
<div class="navigation">
<ul class="list-group">
<li class="list-group-item" ng-click="changeIndex(0)">Home<span class="status-icon"></span></li>
<li class="list-group-item" ng-click="changeIndex(1)">Sign Up<span class="status-icon"></span></li>
<li class="list-group-item" ng-click="changeIndex(2)">About<span class="status-icon"></span></li>
</ul>
</div>
<div class="content">
<div ng-if="pageIndex == 0" ng-include ="'Home.html'"></div>
<div ng-if="pageIndex == 1" ng-include = "'SignUp.html'"></div>
<div ng-if="pageIndex == 2" ng-include = "'About.html'"></div>
</div>

I want to pass the html element into angularjs code. I have some html elements like data-form-selector='#linechart_general_form' and data-url="{% url 'horizon:admin:metering:samples'%}" I want to access these Html elements in angularjs code.
My html templates, what make to change in the following code so that its elements accessible to angularjs code.
<div class="info row detail">
<div class="col-sm-9 chart_container">
<div class="chart"
data-chart-type="line_chart"
data-url="{% url 'horizon:admin:metering:samples'%}"
data-form-selector='#linechart_general_form'
data-legend-selector="#legend"
data-smoother-selector="#smoother"
data-slider-selector="#slider">
</div>
<div id="slider"></div>
<div class="col-sm-3 legend_container">
<div id="smoother" title="Smoothing"></div>
<div id="legend"></div>
</div>
</div>
</div>
--Update-- I just reread your question. To access those ATTRIBUTES (not elements, they are values of an element) you can select the object with an identifier, then manipulate it's attributes, like so (jQuery example):
$('.chart').attr('data-form-selector', 'myNewValue');
You may need to re-initialize sopmething because of the databinding but that's where I'd start.
==================================
You need to create an angular app and controller first, then use the angularjs and ng-model directive to bind the element to a method in your controller, i.e.:
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.firstName= "John";
$scope.lastName= "Doe";
});
</script>
<div ng-app="myApp" ng-controller="myCtrl">
First Name: <input type="text" ng-model="firstName"><br>
Last Name: <input type="text" ng-model="lastName"><br>
<br>
Full Name: {{firstName + " " + lastName}}
</div>
In this case, you'd be manipulating the $scope.firstName and $scope.lastName variables in js.

You can do a Directive for doing that.

I'm using AngularJS and trying to create a form where I can dynamically add new inputs, similar to this fiddle: http://jsfiddle.net/V4BqE/ (Main HTML below, working code in fiddle).
<div ng-app="myApp" ng-controller="MyCtrl">
<div add-input>
<button>add input</button>
</div>
</div>
I would like to be able to use a HTML template for my form since the input I'm adding is ~300 lines long. My issue is I cannot figure out how to index the scope variable containing the data when used in a template. I've tried to make my own modified version of the above code on plnkr http://plnkr.co/edit/4zeaFoDeX0sGTuBMCQP2?p=info . However, when I click the button no form elements appear.
Online (plnkr) I get a 404 not found for my template.html, but I think that is just a plnkr limitation. On my machine with a Python HttpServer I get an Error: [$parse:syntax] for the $templateRequest and a TypeError: Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node'. when using the $http.get method.
Any advice for getting the indexed scope variable array to work with an external html file?
Thanks, JR
Edit: Update plnkr link
You can do it without directive & external template
what you are trying to do does not require a directive (it actually much simple with the basic angularjs tools)

};
// This is just so you can see the array values changing and working! Check your console as you're typing in the inputs :)
$scope.$watch('telephoneNumbers', function(value) {

I'm trying to use Angular to create a tool that accepts user input from a slider tool, and automatically updates an "estimate" field whenever the values are changed. However, the data only seems to be binding on the way to the view; the user input is displayed, but doesn't seem to register in the scope.
Here's the HTML:
<h3 ng-controller="calcController" ng-model="estimate" class="floating-menu">${{estimate}}</h3>
<form ng-controller="calcController" method="post" action="/estimate">
<div class="container">
<div class="vals">${{values.insurance}}</div>
<div id="insurance-slider">
<slider floor="0" ceiling="250" value="125" step="25" precision="2" ng-model="values.insurance" ng-change="changeVal()" translate="currencyFormatting"></slider>
</div>
<div class="container">
<div class="vals">${{values.lease}}</div>
<div id="lease-slider">
<slider floor="0" ceiling="250" value="125" step="25" precision="2" ng-model="values.lease" translate="currencyFormatting"></slider>
</div>
</div>
</form>
Here's the Angular:
//create the module
angular.module('Breeze', ['ngRoute', 'ngResource', 'ui.slider'])
.config(function($routeProvider) {
$routeProvider
// route for the calculator page
.when('/', {
templateUrl: 'partials/calculator.html',
controller: 'calcController'
});
})
// create the controller and inject Angular's $scope
.controller('calcController', function($scope, $http) {
$scope.values = {
// Default values
insurance: 125,
lease: 125,
};
$scope.estimate = $scope.values.insurance + $scope.values.lease
}
// Formatting for scale bar
$scope.currencyFormatting = function(value) {
return value.toString() + " $";
}
})
I've tried adding a $watch and a $broadcast function but can't seem to get them working.
This is what it looked like in Angular:
$scope.$watch("values", function(newVal, oldVal, scope) {
scope.estimate = addVals();
})
$scope.changeVal = function() {
$scope.estimate = addVals();
console.log('hi')
$scope.estimate = $scope.values.insurance + $scope.values.lease
}
Ideas?
You are using two nested ng-controller="calcController"in your HTML. Hence two instanciations of the controller (two $scope) which will have their own estimate value, so when you update the inner estimate, the upper one is not aware of that.
You should remove the second ng-controller in your <form> (if the controller were different, then you would put the estimate variable in an object such as $scope.model.estimate so properties inheritance between the two controllers actually work. But in your case there is no reason to have two controllers).
Also, you should remove that ng-model="estimate" in your <h3> tag, which has no effect.
Just setting them equal in the beginning wont work. In your view, instead of having an estimate field just use this
<div ng-controller="calcController" ng-app="Breeze">
<h3 ng-model="estimate" class="floating-menu">${{values.insurance + values.lease }}</h3>
<form method="post" action="/estimate">
<div class="container">
<div class="vals">${{values.insurance}}</div>
<div id="insurance-slider">
<slider floor="0" ceiling="250" value="125" step="25" precision="2" ng-model="values.insurance" ng-change="changeVal()" translate="currencyFormatting"></slider>
</div>
<div class="container">
<div class="vals">${{values.lease}}</div>
<div id="lease-slider">
<slider floor="0" ceiling="250" value="125" step="25" precision="2" ng-model="values.lease" translate="currencyFormatting"></slider>
</div>
</div>
</div>
</form>
</div>
This will keep them adding as the values change.
Another thing that would be breaking is that you have two controller calls to the same controller and no app. Need to change it as below with the new div and remove the rest of the ng-controllers.
Also, make sure that you have the ui slide javascript file included on your page.
Did you try to bind to object instead of primitive type?
$scope.values.estimate = $scope.values.insurance + $scope.values.lease

Angularjs: 2 way binding not working in included template
Here is a fiddle http://jsfiddle.net/U3pVM/9330/
I am trying to display a binary tree of elements, which I go through recursively with ng-include.
What is the difference between ng-init="item = item.left" and ng-repeat="item in item.left" ?
In this example it behaves exactly the same, but I use similiar code in a project and there it behaves differently. I suppose it's because of Angular scopes.
Maybe I shouldn't use ng-if, please explain me how to do it better.
The pane.html is:
<div ng-if="!isArray(item.left)">
<div ng-repeat="item in [item.left]" ng-include="'Views/pane.html'">
</div>
</div>
<div ng-if="isArray(item.left)">
{{item.left[0]}}
</div>
<div ng-if="!isArray(item.right)">
<div ng-repeat="item in [item.right]" ng-include="'Views/pane.html'">
</div>
</div>
<div ng-if="isArray(item.right)">
{{item.right[0]}}
</div>
<div ng-if="!isArray(item.left)">
<div ng-init = "item = item.left" ng-include="'Views/pane.html'">
</div>
</div>
<div ng-if="isArray(item.left)">
{{item.left[0]}}
</div>
<div ng-if="!isArray(item.right)">
<div ng-init="item = item.right" ng-include="'Views/pane.html'">
</div>
</div>
<div ng-if="isArray(item.right)">
{{item.right[0]}}
</div>
The controller is:
var app = angular.module('mycontrollers', []);
app.controller('MainCtrl', function ($scope) {
$scope.tree = {
left: {
left: ["leftleft"],
right: {
left: ["leftrightleft"],
right: ["leftrightright"]
}
},
right: {
left: ["rightleft"],
right: ["rightright"]
}
};
$scope.isArray = function (item) {
return Array.isArray(item);
}
});
EDIT:
First I run into the problem that the directive ng-repeat has a greater priority than ng-if. I tried to combine them, which failed. IMO it's strange that ng-repeat dominates ng-if.
It's a little hacky, but I am passing variables to an ng-include with an ng-repeat of an array containing a JSON object :
<div ng-repeat="pass in [{'text':'hello'}]" ng-include="'includepage.html'"></div>
In your include page you can access your variable like this:
<p>{{pass.text}}</p>
Pass parameter to Angular ng-include
You don't need that. all ng-include's sources have the same controller. So each view sees the same data.
What is the difference between ng-init="item = item.left" and ng-repeat="item in item.left"
[1]
ng-init="item = item.left" means - creating new instance named item that equals to item.left. In other words you achieve the same by writing in controller:
$scope.item = $scope.item.left
[2]
ng-repeat="item in item.left" means create list of scopes based on item.left array. You should know that each item in ng-repeat has its private scope
I am trying to display a binary tree of elements, which I go through recursively with ng-include.
I posted in the past answer how to display tree by using ng-include.
It might helpful: how-do-display-a-collapsible-tree
The main part here that you create Node with id wrapped by <scipt> tag and use ng-repeat:
<script type="text/ng-template" id="tree_item_renderer">
<ul class="some" ng-show="data.show">
<li ng-repeat="data in data.nodes" class="parent_li" ng-include="'tree_item_renderer'" tree-node></li>
</ul>
</script>
<ul>
<li ng-repeat="data in displayTree" ng-include="'tree_item_renderer'"></li>
Making a generic directive instead of ng-include is a cleaner solution:
Angular passing scope to ng-include
I am using ng-include with ng-repeat of an array containing string. If you want to send multple data so please see Junus Ergin answer.
See my code Snippet:
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="">
<div ng-repeat="name in ['Sanjib Pradhan']" ng-include="'your_template.html'"></div>
<div ng-repeat="name in ['Chinmay Sahu']" ng-include="'your_template.html'"></div>
<script type="text/ng-template" id="your_template.html">
