I am developing in angular js. Previously, i use ng-include with url. But how could i point the url to templatecache?
<ng-include
src="string"
[onload="string"]
[autoscroll="string"]>
...
</ng-include>
Template cache uses a key for identifying the cached elements, so you can use the key for that.
$templateCache.put('MY KEY', 'Cached content');
And in the html:
<ng-include src="'MY KEY'"></ng-include>
See it on AngularJS docs for $templateCache.
There are two ways:
In markup:
Specify your template as a script tag:
<script type="text/ng-template" id="templateId.html">
<p>This is the content of the template</p>
</script>
(this should be a descendant of your ng-app, in other words it should be specified somewhere inside the ng-app markup)
This will automatically cache the template.
In code:
var myApp = angular.module('myApp', []);
myApp.run(function($templateCache) {
$templateCache.put('templateId.html', 'This is the content of the template');
});
In both the cases, you can get the cached template like this:
<div ng-include=" 'templateId.html' "></div>
or
$templateCache.get('templateId.html')

I'm trying to add two angular apps / modules to one page.
In the fiddles below you can see that always only the first module, referenced in the html code, will work correctly, whereas the second is not recognized by angular.
In this fiddle we can only execute the doSearch2 method, whereas in this fiddle only the doSearch method works correctly.
I'm looking for the way how to correctly place two angular modules into one page.
Only one AngularJS application can be auto-bootstrapped per HTML document. The first ngApp found in the document will be used to define the root element to auto-bootstrap as an application. To run multiple applications in an HTML document you must manually bootstrap them using angular.bootstrap instead. AngularJS applications cannot be nested within each other.

I created an alternative directive that doesn't have ngApp's limitations. It's called ngModule. This is what you code would look like when you use it:
<!DOCTYPE html>
<html>
<head>
<script src="angular.js"></script>
<script src="angular.ng-modules.js"></script>
<script>
var moduleA = angular.module("MyModuleA", []);
moduleA.controller("MyControllerA", function($scope) {
$scope.name = "Bob A";
});
var moduleB = angular.module("MyModuleB", []);
moduleB.controller("MyControllerB", function($scope) {
$scope.name = "Steve B";
});
</script>
</head>
<body>
<div ng-modules="MyModuleA, MyModuleB">
<h1>Module A, B</h1>
<div ng-controller="MyControllerA">
{{name}}
</div>
<div ng-controller="MyControllerB">
{{name}}
</div>
</div>
<div ng-module="MyModuleB">
<h1>Just Module B</h1>
<div ng-controller="MyControllerB">
{{name}}
</div>
</div>
</body>
</html>

It's essentially the same code used internally by AngularJS without the limitations.
Why do you want to use multiple [ng-app] ? Since Angular is resumed by using modules, you can use an app that use multiple dependencies.
Javascript:
// setter syntax -> initializing other module for demonstration
angular.module('otherModule', []);
angular.module('app', ['otherModule'])
.controller('AppController', function () {
// ...do something
});
// getter syntax
angular.module('otherModule')
.controller('OtherController', function () {
// ...do something
});
HTML:
<div ng-app="app">
<div ng-controller="AppController">...</div>
<div ng-controller="OtherController">...</div>
</div>
EDIT
Keep in mind that if you want to use controller inside controller you have to use the controllerAs syntax, like so:
<div ng-app="app">
<div ng-controller="AppController as app">
<div ng-controller="OtherController as other">...</div>
</div>
</div>
You can bootstrap multiple angular applications, but:
1) You need to manually bootstrap them
2) You should not use "document" as the root, but the node where the angular interface is contained to:
var todoRootNode = jQuery('[ng-controller=TodoController]');
angular.bootstrap(todoRootNode, ['TodoApp']);
This would be safe.
Manual bootstrapping both the modules will work. Look at this
<!-- IN HTML -->
<div id="dvFirst">
<div ng-controller="FirstController">
<p>1: {{ desc }}</p>
</div>
</div>
<div id="dvSecond">
<div ng-controller="SecondController ">
<p>2: {{ desc }}</p>
</div>
</div>
// IN SCRIPT
var dvFirst = document.getElementById('dvFirst');
var dvSecond = document.getElementById('dvSecond');
angular.element(document).ready(function() {
angular.bootstrap(dvFirst, ['firstApp']);
angular.bootstrap(dvSecond, ['secondApp']);
});

I have quite a big form and was looking at ngMessages. I wanted to implement this:
<script type="text/ng-template" id="error-messages">
<div ng-message="required">This field is required</div>
<div ng-message="minlength">This field is too short</div>
</script>
would I make a factory method? so I could use it across many different controllers? as the project will have many forms in it? I am not sure how to include this in a factory if that is the correct way. This is what I was thinking whether it is right or not.
(function() {
"use strict";
angular.module("minorApp")
.factory("errorMessage", []);
function errorMessage() {
return // some template
}
})();
You can add the template to angular's template cache:
var myApp = angular.module('myApp', []);
myApp.run(function($templateCache) {
$templateCache.put('error-messages.html', '<div ng-message="required">This field is required</div><div ng-message="minlength">This field is too short</div>');
});
Then, reference it in the html documents where you want to include it using ng-include.
<div ng-include src="'error-messages.html'"></div>
If you are using a build system like gulp, you can keep your html in .html files and using the https://www.npmjs.com/package/gulp-angular-templatecache plugin to automate the process of adding them to angular's template cache.
I am trying to create a tooltip based from from this post
Angular-UI-Bootstrap custom tooltip/popover with 2-way data-binding
I successfully created the popup but I have trouble delivering the content to my popover.html
I added this to my script.js
var app = angular.module('myApp', ['ui.bootstrap', 'ian.bootstrap']);
app.controller('myCtrl', function ($scope) {
$scope.item = {
title: 'Original Title',
content:'content 1' //newly added item
};
$scope.text = 'Click me';
});
and I want to display it in my popover.html
<div class="popover-content">
{{item.content}}
</div>
It doesn't show anything. Can someone help me about it? thanks a lot!
my plunker

Here is your updated working Plunkr
Basically you have to pass the attr iantooltip-content with the binding of the content item, not the raw text, and after in the directive pass in the directive isolate scope options the binding of the content like :
iantooltipContent: '='
Just change the appenToBody variable and you're done.
You should read the docs for more infos about Angular directive :)
You can add the ng-controller in your div and then specify the controller name like so :
<div class="popover-content" ng-controller='myCtrl'>
{{item.content}}
</div>
Before the use cases, the basic syntax to create a custom directive.
For all the code samples in this page I started from the angular-seed template.
Starting from the angular-seed skeleton is quite easy to extract a model to begin to implement custom directives.
<html ngApp="myApp">
...
<div my-first-directive></div>
<script src="lib/angular/angular.js"></script>
<script src="js/app.js"></script>
<script src="js/directives.js"></script>
...
</html>

How do I make a jsfiddle out of the following code:
<html>
<head>
</head>
<body>
<div ng-app ng-controller="MainCtrl">
<ul>
<li ng-repeat="num in nums">
{{num}}
</li>
</ul>
</div>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.4/angular.js"></script>
<script type="text/javascript" charset="utf-8">
function MainCtrl($scope) {
$scope.nums = ["1","2"];
}
</script>
</body>
</html>
My non working attempt: http://jsfiddle.net/zhon/3DHjg/ shows nothing and has errors.
You need to set some things up in jsFiddle for this to work.
First, on the left panel, under "Frameworks & Extensions", select "No wrap - in <body>".
Now, under "Fiddle Options", change "Body tag" to <body ng-app='myApp'>
In the JS panel, initiate your module:
var app = angular.module('myApp', []);
Check it out: http://jsfiddle.net/VSph2/1/
#pkozlowski.opensource has a nice blog post about how to use jsFiddle to write AngularJS sample programs.
You've defined your controller in a function scope that is not accessible to angular (angular is not yet loaded). In other words you are trying to call angular library's functions and helpers like below example before getting angular library loaded.
function onload(){
function MainCtrl(){}
}
To resolve this, switch your angular load type to be No wrap - in <body> like shown in screenshot.
here is a working example in jsfiddle
Click JAVASCRIPT button, choose angular version and place where u want include loaded script:
Then click HTML button and add ng-app in body tag. Its all:)
I am writing my answer for those who land on this page , I was used to use ng-module directive but in jsfiddle after half an hour I realized that ng-module is not allowed and you see no error , and when changed that ng-module to ng-app fiddle worked very well .I just wanted to share this .And no wrap (body) is required too.
<div ng-app="appX" ng-controller="appCtrl">
<p>{{greeting}}
</p>
</div>
var app=angular.module("appX",[]);
console.log(app);
app.controller("appCtrl",function($scope){
$scope.greeting="Hello World";
});
https://jsfiddle.net/cloudnine/trgrjwf1/7/
Since Angular 1.4.8 has been chosen by JSFiddle as the top option for Angular V1 in its JAVASCRIPT setting panel, more restriction applies: both ng-app and ng-controller should be declared in HTML to make it work.
Sample HTML:
<div ng-app="myApp" ng-controller="myCtrl">
<input type="text" ng-model="sample" placeholder="type something here...">
<span>{{sample}}</span>
</div>
Sample JS:
angular.module('myApp', [])
.controller('myCtrl', function($scope) {});
