learn angularjs at codeacademy

I learn angularjs and build some code from scratch. The first, it show up the skeleton of website structure.


wwwroot:
-CSS
++main.css                -->css how your website style
-IMG                         -->image for your website
++someIMG
-JS
++CONTROLLERs
++++maincontroller.js --->main controller
++SHARED                -->include angularjs support library
++++angular-mocks.js
++++angular-route.min.js
++++angular.min.js
++app.js            -->call into action
-INDEX.HTML--->the start point
Start point include 6 steps from introduction:
Awesome! You built an AngularJS app. How does it work?
  1. In app.js, we created a new module named myApp. A module contains the different components of an AngularJS app.
  2. Then, in index.html we added <body ng-app="myApp">. The ng-app is called a directive. It tells AngularJS that the myApp module will live within the <body> element, termed the application's scope. In other words, we used the ng-app directive to define the application scope.
  3. In MainController.js we created a new controller namedMainController. A controller manages the app's data. Here we use the property title to store a string, and attach it to $scope.
  4. Then, in index.html, we added<div class="main" ng-controller="MainController">. Likeng-app, ng-controller is a directive that defines the controller scope. This means that properties attached to $scope in MainControllerbecome available to use within <div class="main">.
  5. Inside <div class="main"> we accessed $scope.title using{{ title }}. This is called an expression. Expressions are used to display values on the page.
  6. The value of title showed up when we viewed the app in the browser.
  7. The same framework we can see there: the View-the Controller

league of legend, boring patch 6.9

league of legend, boring patch 6.9 I was down my rank 2 form silver 3 to silver 5 after losing 10 matches continuous. That game increasingly bored, I don't know why the match find the team like that. It's unreasonable. I can't 1 vs 5 with the enemy team. The gamer, did not even know how to play, go to play the ranked game. I try to play top, mid, bot, support but it's not effective. I up my rank from bronze IV to silver 3, almost silver 2 during 2 month but down 2 ranks in about 1 week. I wonder why this system go like that. If you have skill, you will be the key to win this battle but you can't versus all the enemy. Your friends feed too much. they don't know how to combat. They always attack the first foe that is a hard tank, and so, the opponent ' ADC AP kill us all. It's terrible if you want to win but you can't. I confuse in this situation. How can I play to control the combat and win. Their attitude is bad in this game. They play and sh...
