I'm newbie to angularjs. When I read the docs, I found it uses ng as prefix of attributes:
<body ng:controller="PhoneListCtrl">
<ul>
<li ng:repeat="phone in phones">
{{phone.name}}
<p>{{phone.snippet}}</p>
</li>
</ul>
</body>
I want to know if I can modify it as another word, such as x? Since I think x is much easier to type than ng.
Since v1.0.0rc1, these are all equivalent:
<div ng-show="isVisible">Using ng-show</div>
<div ng:show="isVisible">Using ng:show</div>
<div data-ng-show="isVisible">Using data-ng-show</div>
<div x-ng-show="isVisible">Using x-ng-show</div>
<div class="ng-show:isVisible">Using class="ng-show:isVisible"</div>
Here's working fiddle:

However, the main reason behind this was allowing valid html. So, you ca use x-* prefix for your custom directives, but not for Angular ones.

I am trying to use ng-repeat to spit out part of a url (my.url) within ng-include. Unfortunately I cant seem to get it to work. It works when I dont place it within an ng-include, so I know that part isnt the issue. THe issue seems to be when I place {{my.url}} inside ng-repeat and attached to the first (static) part of the url.
What i am aiming for is the ng-include to use "filepath/filepath/mypage.html
my.url is the mypage.html bit.
Anybody able to advise?
<uib-tab ng-repeat="stuff in myList" heading="{{my.text}}" class="sg-tabbed-titles">
<div class="tab">
<ul class="tabbed-list">
<li class="tab-content">
<div ng-include="'\filepath/filepath/{{my.url}}\'"></div>
</li>
It should be
<div ng-include="'filepath/filepath/' + my.url"></div>
ngInclude takes expression. It means that you need to use normal string concatenation just like you would do in regular javascript code.
I am new to Angular.js and want to use one ng-controller within another ng-app and ng-controller like this so that I will be able to use the code before I used on the other pages as well.
Please help me out and correct me if I am wrong anywhere.
<div id="divFriendList" class="container" ng-app="friendModule" ng-controller="friendController">
<div id="module2" ng-app="cardsModule" ng-controller="CardsController">
<div ng-repeat="card in cards></div>
</div>
</div>
I am rather new as well, but I believe a way to do this would be to declare a dependency in your module. For example, angular.module('friendModule', ['cardsModule']);. Such an example can be found here. For more about modules and a tutorial on angular you can visit W3Schools.
As for your code, you're missing the closing quotation in <div ng-repeat="card in cards>. Further, you are asking ng-repeat to iterate each card in cards, but you have not defined what cards is. Therefore, you'll want to change
<div id="module2" ng-app="cardsModule" ng-controller="CardsController">
to
<div id="module2" ng-app="cardsModule" ng-controller="CardsController as cards">.
Additionally, you will not get any information displayed if you don't ask for an output such as {{card}}. I would also consider declaring your ng-apps before hand and not when they're needed - but I'm unsure as to the efficiency of this.
What I would update as:
<div id="divFriendList" class="container" ng-app="friendModule" ng-controller="friendController">
<div id="module2" ng-app="cardsModule" ng-controller="CardsController as cards">
<div ng-repeat="card in cards">{{ card }}</div>
</div>
</div>
Hope that helps.
I may have worded this title incorrectly but I am hoping to still get some help. I am trying to use an expression that I get from an ng-repeat to include an new page using ng-include but it is not rendering. I can write in the page I want, but I want to use the expression to include multiple pages dynamically
<div ng-app="" id="container" ng-controller="pagesController">
<span ng-repeat="x in pages">
{{x.Page | uppercase}}
<b ng-if="!$last" href="#"> - </b>
<div ng-include="'{{x.HTML}}'" name="{{x.Page}}"></div>
</span>
But if I manually enter the pages like so:
<div ng-include="'generic.htm'" name="generic"></div>
It works as expected.
I am getting used to Angular.js obviously and I am not sure if this is possible or if I can do what I want really. Any help would be appreciated.
ng-include is an angular directive, and assuming x.HTML is a string, omit the {{}} and the single quotes:
ng-include="x.HTML"
I still want {{1+2}} to be evaluated as normal. But in addition to the normal interpolator, I want to create a custom one that I can program to do whatever I want.
e.g. <p>[[welcome_message]]</p> should be a shortcut for <p>{{'welcome_message' | translate}}</p>, or <p translate="welcome_message"></p>. That way, i18n apps would be much more convenient to write.
Is anything like that possible? I'm currently going through the angular.js source code, but the interpolation system looks pretty complicated(?). Any suggestions?
I created a directive that regex-find-replaces it's innerHTML. Basically, I can rewrite any text into any other text. Here's how I did it:
How do I make angular.js reevaluate / recompile inner html?
Now all I have to do is to place my directive-attribute, "autotranslate", in one of the parent elements of where I want my interpolator to work, and it rewrites it however I want it! :D
<div class="panel panel-default" autotranslate>
<div class="panel-heading">[[WELCOME]]</div>
<div class="panel-body">
[[HELLO_WORLD]
</div>
</div>
becomes
<div class="panel panel-default" autotranslate>
<div class="panel-heading"><span translate="WELCOME"></span></div>
<div class="panel-body">
<span translate="HELLO_WORLD"></span>
</div>
</div>
which does exactly what I wanted.
I don't think that's possible, but if you really want to save some characters you could create a function on your rootScope called t, then call it within your views:
<p>{{ t(welcome_message) }}</p>
I have a HTML file it iterates over a list of objects as shown and every object has a template( stored in the db) that it uses I get "List" from a web service :-
<ul>
<li ng-repeat="object in List" ng-include="object.TemplateName" > </li>
</ul>
Let object.TemplateName be "template1"
A sample template would have a specific directive with the attributes needed and few html tags as shown "template1":-
template1:-
<directive1 s-web-service-path="object.WebServicePath" >
<h1>any html content</h1>
</directive1>
my directive calls a web service to get the content to be displayed and has its own template... instead of putting directives in a template and including them cant I directly call my directive depending upon the different types of objects that i obtain in List
something like
for Object.Type="1" i call directive1 instead of template1
for Object.Type="2" i call directive2 instead of template2
ngIf or ngSwitch might be helpful here, with a few extra wrapping elements within the ngRepeat, in order to dynamically choose what to include based on Object.Type. Using ngSwitch:
<ul>
<li ng-repeat="object in List">
<div ng-switch="object.Type">
<div ng-switch-when="'1'">
<div ng-include="object.TemplateName"></div>
</div>
<div ng-switch-when="'2'">
<directive1 s-web-service-path="object.WebServicePath" >
<h1>any html content</h1>
</directive1>
</div>
</div>
</li>
</ul>
The above is not tested, so there could potentially be an error. You might also be able to cut down on some of DOM nesting level by including the ng-switch-when attributes on the directive1 / ng-include divs, but the way above makes the behaviour clear, and avoids any unexpected issues that might arise from having multiple directives work on the same element.
