[AngularJS] 實作簡單的multipart uplaod

簡單記錄一下ng處理上傳的相關資源
Please note that solutions that use FormData(), such as the ones presented here in other answers, do not work correctly in older IE browsers.

The correct solution should use a backup strategy for that, such as using iFrames. There are already many angular JS modules to perform file uploading:

[Alfresco] 上傳大檔的相關問題筆記


先前處理alfresco上傳的議題
  1. Heap Size issue (Need to increase that) 
  2. JVM memory allocation 
  3. session time out (It will take more time to write the data on created content so need to make sure session timeout does not happens)

[jQuery plugin] 使用同一個驗證規則來驗證多個textobx欄位

今天有個畫面需求,需用驗證多個textbox (也可以動態產生),使用同一個規則。 一般來說jquery validator只會驗證一個元素(假設你有多個name故意一樣,也只有一個會被驗證)

以下這個StackoverFlow討論串有提供另一個解法:

[AngularJS] 自訂directive控制圖片找不到

如果遇到頁面的圖片載入失敗時,通常會load預設的圖片,避免有叉燒包的情況。
可以自建一個directive來處理此事件

以下是Stackoverflow的解法:
http://stackoverflow.com/questions/16310298/if-a-ngsrc-path-resolves-to-a-404-is-there-a-way-to-fallback-to-a-default


app.directive('errSrc', function() {
  return {
    link: function(scope, element, attrs) {

      scope.$watch(function() {
          return attrs['ngSrc'];
        }, function (value) {
          if (!value) {
            element.attr('src', attrs.errSrc);
          }
      });

      element.bind('error', function() {
        element.attr('src', attrs.errSrc);
      });
    }
  }
})

[Angular] MVC MVVM MVP 說文解字

常見的 MVC MVVM MVP 框架說文解字

MVC vs MVVM vs MVP. What a controversial topic that many developers can spend hours and hours debating and arguing about.

For several years +AngularJS was closer to MVC (or rather one of its client-side variants), but over time and thanks to many refactorings and api improvements, it'snow closer to MVVM – the $scope object could be considered the ViewModel that is being decorated by a function that we call a Controller.

Being able to categorize a framework and put it into one of the MV* buckets has some advantages. It can help developers get more comfortable with its apis by making it easier to create a mental model that represents the application that is being built with the framework. It can also help to establish terminology that is used by developers.

Having said, I'd rather see developers build kick-ass apps that are well-designed and follow separation of concerns, than see them waste time arguing about MV* nonsense. And for this reason, I hereby declare AngularJS to be MVW framework - Model-View-Whatever. Where Whatever stands for "whatever works for you".

Angular gives you a lot of flexibility to nicely separate presentation logic from business logic and presentation state. Please use it fuel your productivity and application maintainability rather than heated discussions about things that at the end of the day don't matter that much.

[AngularJS] angular 執行順序

這篇文章回應了angular app執行順序:D 附執行範例。

http://stackoverflow.com/questions/20663076/angularjs-app-run-documentation

Here's the calling order:
  1. app.config()
  2. app.run()
  3. directive's compile functions (if they are found in the dom)
  4. app.controller()
  5. directive's link functions (again if found)
Here's a simple demo where you can watch each execute (and experiment if you'd like).
Run blocks - get executed after the injector is created and are used to kickstart the application. Only instances and constants can be injected into run blocks. This is to prevent further system configuration during application run time.
Run blocks are the closest thing in Angular to the main method. A run block is the code which needs to run to kickstart the application. It is executed after all of the service have been configured and the injector has been created. Run blocks typically contain code which is hard to unit-test, and for this reason should be declared in isolated modules, so that they can be ignored in the unit-tests.
One place you see run blocks used is for authentication
<div ng-app="myApp" ng-controller="myCtrl">
    <div test1 test2> </div>
</div>
var myApp = angular.module('myApp', []);
myApp.factory('aProvider', function() {
   console.log("factory");
});
 
myApp.directive("test1", function() {
    console.log("directive setup");
    return {
        compile: function() {console.log("directive compile");}
    }
});
 
myApp.directive("test2", function() {
    return {
        link: function() {console.log("directive link");}
    }
});
 
myApp.run(function() {
    console.log("app run");
});
 
myApp.config( function() {
    console.log("app config");
});
 
myApp.controller('myCtrl', function($scope) {
    console.log("app controller");
});
