jquery angularjs javascript development programming

  • Angular does not treat HTML or JavaScript as a bug that needs to be fixed
  • JavaScript code treats DOM in an imperative manner: take this node and that attribute, look at its value, do this or that.
  • Direct manipulation of the DOM is not only unnecessary, it is discouraged in the Angular approach.
  • ...11 more annotations...
  • DOM should be specified in views
  • data in scopes
  • functionality in controller
  • non-trivial transformations in custom filters and directives.
  • Binding a DOM value to a model in a controller scope
  • Any controller that needs to use this JSON data, can do so by including DataSource as one of the controller parameters
  • Include $http in the parameters.
  • Include $log as your controller function argument.
  • What happens internally is this: Angular analyzes your function’s source code, finds the arguments, and infers from them the services your code requires.

      這段好像就是在講丟參數進去時，AngularJS 會判斷。 不管順序，但是名稱好像需要固定，而且要有 $ 號。
  • Angular predefines reasonable defaults for getting, setting, deleting, and querying records.

  • in AngularJS, we have a separate model layer that we can manage in any way we want, completely independently from the view.
  • keep your concerns separate
  • do DOM manipulation and augment your view with directives
  • ...34 more annotations...
  • DI means that you can declare components very freely and then from any other component, just ask for an instance of it and it will be granted
  • do test-driven development iteratively in AngularJS!
  • only do DOM manipulation in a directive
  • with ngClass we can dynamically update the class;
  • ngBind allows two-way data binding;
  • ngShow and ngHide programmatically show or hide an element;
  • The less DOM manipulation, the easier directives are to test, the easier they are to style, the easier they are to change in the future, and the more re-usable and distributable they are.
  • still wrong.
  • Before doing DOM manipulation anywhere in your application, ask yourself if you really need to.
  • a few things wrong with this
  • jQuery was never necessary
  • use angular.element and our component will still work when dropped into a project that doesn't have jQuery.
  • just use angular.element
  • the element that is passed to the link function would already be a jQuery element!
  • directives aren't just collections of jQuery-like functions
  • Directives are actually extensions of HTML
  • If HTML doesn't do something you need it to do, you write a directive to do it for you, and then use it just as if it was part of HTML.
  • think how the team would accomplish it to fit right in with ngClick, ngClass, et al.
  • Don't even use jQuery. Don't even include it.
  • ry to think about how to do it within the confines the AngularJS.
  • In jQuery, selectors are used to find DOM elements and then bind/register event handlers to them.
  • Views are (declarative) HTML that contain AngularJS directives
  • Directives set up the event handlers behind the scenes for us and give us dynamic databinding.
  • Views are tied to models (via scopes). Views are a projection of the model
  • In AngularJS, think about models, rather than jQuery-selected DOM elements that hold your data.
  • AngularJS uses controllers and directives (each of which can have their own controller, and/or compile and linking functions) to remove behavior from the view/structure (HTML). Angular also has services and filters to help separate/organize your application.
  • Think about your models
  • Think about how you want to present your models -- your views.
  • using the necessary directives to get dynamic databinding.
  • Attach a controller to each view (using ng-view and routing, or ng-controller)
  • Make controllers as thin as possible.
  • You can do a lot with jQuery without knowing about how JavaScript prototypal inheritance works.
  • jQuery is a library
  • AngularJS is a beautiful client-side framework

    "the reason to use the bar is because you're switching content via JavaScript rather than loading a new page. This makes sense since the browser's own loading indicator may not get triggered. "

  • Cake views are just presentation-flavored fragments that fit inside an application’s layout. For most applications they’re HTML mixed with PHP, but they may end up as XML, CSV, or even binary data.
  • Layouts are presentation code that is wrapped around a view, and can be defined and switched between
  • if the HTTP method of the request was POST, try to save the data using the Post model.
  • ...6 more annotations...
  • You can also specify URLs relative to the base of the application in the form of /controller/action/param1/param2.
  • Every CakePHP request includes a CakeRequest object which is accessible using $this->request.
  • When a user uses a form to POST data to your application, that information is available in $this->request->data.
  • The $this->Form->input() method is used to create form elements of the same name.
  • postLink() will create a link that uses Javascript to do a POST request deleting our post.
  • Allowing content to be deleted using GET requests is dangerous
