Slavery made all crops MORE profitable. If you're talking about America, slaves were brought to the Caribbean to cut sugar cane in droves. This is probably the biggest crop usâ¦ing most slaves initially. Cotton became a big slave labor driven industry in the 19th century for several reasons.
How to Use a Filter in a Controller in AngularJS. In this post, I am sharing how to use a filter in a controller in AngularJS. Very easy way of injecting a filter is to inject dependency with the name composed of the filter name and the Filter suffix: .E.g. the dependency customFilter injects custom filter.The injected component is a filter function.Note that you can use this approache to inject filter also to services and directives.Following example injects filter called custom. Another way is to inject $filter dependency to your controller and fetch required filter inside the controller.he injected component is a filter function. Note that you can use this approache to inject filter also to services and directives. Following example injects filter called custom. Another way is to inject $filter dependency to your controller and fetch required filter inside the controller.
Hereâs a basic module, service, and controller in Angular: angular.module('myApp.service',[]); angular.module('myApp',['myApp.service']); var StatesController = function($scope) {}. On the first line is a service named âmyApp.serviceâ. Note that the dot is not necessary, nor is using the app name as a prefix. I could have named it âgoferâ if I wanted. The important part is that I let the main application module know the name, which brings me to line 2, the main module. The main module names the app and gives it a a comma delimited reference to services, filters, etc. that can be referenced. If I defined a filter named âmyApp.filterâ my module definition would have been: âangular.module(âmyAppâ,[âmyApp.serviceâ,âmyApp.filterâ]);â. The module name, âmyAppâ, will be used in my ngApp directive in the template. Line 3 is the shell of a controller definition which will be directly accessible by the template.
