问题
I have called the data from server using ngResource
. however, i have figured out that for some reason, my controller is called twice.
Here is my code;
App.js file
// declare a module
var blogApp = angular.module('blogApp', ['ngResource']);
HomeController.js file;
blogApp.controller("HomeController", function ($scope, $resource) {
var HotNews = $resource('/api/article/hotnews?culture=en-US');
$scope.news = HotNews.query();
alert("hello"); //here i see hello alert box two times
});
my view;
<ul id="news" data-ng-controller="HomeController">
<li data-ng-repeat="headline in news">
{{headline.description}}
<a href="#" title="Read More">» more</a>
</li>
</ul>
Updated: the issue is in fancybox.js
file that is in main layout;
<html data-ng-app="blogApp">
the source files are;
<!-- JS -->
<script src="/Content/scripts/lib/angular.min.js"></script>
<script src="/Content/scripts/lib/angular-resource.min.js"></script>
<script src="/Content/scripts/app/app.js"></script>
<script src="/Content/scripts/app/controllers/HomeController.js"></script>
@Scripts.Render("~/bundles/jquery")
<script src="/content/fancybox/jquery.fancybox-1.3.4.pack.js"></script>
when i comment out the fancybox, all works fine but when i add it back, i get two times alert box;

All looks ok. The problem could be elsewhere. I created a plunker based on the above and executed the controller once. You may want to modify it, add your other code if any and test it out yourself: http://embed.plnkr.co/ttvlTJBhTEd9sQUdkQjX/preview

The main point with this issue for me, was the way the scripts were arranged in my project. So, i comment- out each script one by one, and then i got the issue. The issue was, i was using jquery library called pageslide
, in a situation where i have a button and when a user click on that button, the page were slide to left/right;
SO, i just move all of my angular
related files to the end of all the scripts and now, i don't see the alert()
box two times.
here is the arrangement that works for me;
@Scripts.Render("~/bundles/jquery")
<script src="/Content/fancybox/jquery.fancybox-1.3.4.pack.js"></script>
<script src="/content/scripts/lib/general.js"></script>
<script src="/content/scripts/lib/function.js"></script>
<script src="/content/scripts/lib/styleswitch.js"></script>
<!-- elRTE -->
<script src="/content/scripts/lib/elrte/elrte.min.js" type="text/javascript" charset="utf-8"></script>
<script src="/Content/scripts/app/dataservice.js"></script>
<script src="/Content/scripts/app/statemanager.js"></script>
// this was causing the problem
<script>
$("#allpage-login-top").pageSlide({ width: "350px", direction: "left" });
$("#allpage-signup-top").pageSlide({ width: "350px", direction: "right" });
$("#allpage-search-top").pageSlide({ width: "350px", direction: "left", modal: true });
$("#homepage-login-button").pageSlide({ width: "350px", direction: "left" });
$("#homepage-signup-button").pageSlide({ width: "350px", direction: "right" });
</script>
<!-- JS -->
<script src="/Content/scripts/lib/angular.min.js"></script>
<script src="/Content/scripts/lib/angular-resource.min.js"></script>
<script src="/Content/scripts/app/app.js"></script>
<script src="/Content/scripts/app/controllers/HomeController.js"></script>
@RenderSection("scripts", required: false)
@MiniProfiler.RenderIncludes()
