How to check whether Sitecore item is using alias

阅读更多关于 How to check whether Sitecore item is using alias

问题 Currently an "Alias" in Sitecore will produce multiple routes to the same content item which can negatively affect SEO in some cases. I am looking for a way to programatically check whether the current Page/Item/URL/Request is using an alias or not. I was hoping there would be something along the lines of: Sitecore.Web.WebUtil.IsAlias Any ideas on how to check for aliases? -------UPDATE------- Here is my current solution which appears to work just fine... Unless anyone has a better ideas?:

问题 I'm a little confused about all the different ways to create a new jQuery object. the relevent docs seem to be: http://api.jquery.com/ready/ http://api.jquery.com/jQuery/ From those two docs the following are all equivalent, (with the exception of aliasing or not aliasing '$'): $(document).ready(handler) $().ready(handler) $(handler) jQuery(function($) {}); jQuery(document).ready(function($) {}); Is that correct? Did I miss any? 回答1: Well, there is another. From the docs: There is also $

shell使用别名

阅读更多关于 shell使用别名

在shell脚本中使用alias inux shell有交互式与非交互式两种工作模式。我们日常使用shell输入命令得到结果的方式是交互式的方式，而shell脚本使用的是非交互式方式。 shell提供了alias功能来简化我们的日常操作，使得我们可以为一个复杂的命令取一个简单的名字，从而提高我们的工作效率。在交互式模式下，shell的alias扩展功能是打开的，因此我们可以键入自己定义的alias别名来执行对应的命令。但是，在非交互式模式下alias扩展功能默认是关闭的，此时仍然可以定义alias别名，但是shell不会将alias别名扩展成对应的命令，而是将alias别名本身当作命令执行，如果shell内置命令和PATH中均没有与alias别名同名的命令，则shell会“抱怨”找不到指定的命令。那么，有没有办法在非交互式模式下启用alias扩展呢？答案是使用shell内置命令shopt命令来开启alias扩展选项。shopt是shell的内置命令，可以控制shell功能选项的开启和关闭，从而控制shell的行为。shopt的使用方式如下： shopt -s opt_name Enable (set) opt_name. shopt -u opt_name Disable (unset) opt_name. shopt opt_name Show current status

Is it possible to create a type alias to a generic class in Delphi

问题 I would like to define a class type (type alias) for a generic class. I would like to do this so users of unit b can have access to TMyType without using unit a. I have units like this: unit a; interface type TMyNormalObject = class FData: Integer; end; TMyType<T> = class FData: <T>; end; implementation end. unit b; interface type TMyNormalObject = a.TMyNormalObject; // works TMyType<T> = a.TMyType<T>; // E2508 type parameters not allowed on this type implementation end. I already found a

看laravel源码学习依赖注入

前言初心最近在看设计模式中的依赖注入，希望借助设计模式的神奇魔力，能达到一个目的，然后在此学习的过程中，能收获一个bonus。这个目的就是能使得自己设计的系统更简单更容易理解，或者是使得系统设计的结构和代码更简单，而bonus是企图在设计模式上实现概念上的并发。这篇文章是希望把自己这段时间的学习成果作一个记录和总结，然而并不要太期待，因为目前得出的结论并没有达到我的目的，bonus暂时希望也比较渺茫。在知识网络结构认知上的准备我们需要提前了解一下依赖倒置原则、控制反转和依赖注入的关系。控制反转是一种设计思想，它遵循了依赖倒置原则，而实现控制反转一般主要的方式或者手段是依赖注入。依赖倒置原则本文就不作解释了，我们了解一下即可。唠一唠依赖注入和IoC 依赖注入是什么东西呢这里有几个先行的概念需要描述一下，首先我们要有一个主体，这个主体被注入了依赖，主体通过使用这些依赖去做一些行为或者实施一些操作。主体指的是一些系统设计上的一些实体，比如有一个违规记录类，用于实现创建、修改、审核的业务逻辑，那么这个违规记录类就是一个主体，再比如有一个这样的业务逻辑：违规记录内包含多个违规指标。这时候这个违规指标类，也是一个主体。依赖指的是主体需要依赖另外某个主体实现某个功能

Class alias in scala

问题 Is it possible in Scala to define MyAlias[A] as an alias for MyClass[String, A] . For example, MyAlias[Int] would refer to Map[String, Int] . 回答1: Note that Map is a trait , not a class . You can still alias it using the type keyword: type StringMap[A] = Map[String, A] val myMap: StringMap[Int] = Map("a" -> 1) This can be done within the scope of a class , object or trait definition (and in the scope of any method or expression). Sometimes you'll want the alias to be private to its declaring

Using a 'using alias = class' with generic types? [duplicate]

阅读更多关于 Using a 'using alias = class' with generic types? [duplicate]

This question already has an answer here: Using Statement with Generics: using ISet<> = System.Collections.Generic.ISet<> 6 answers So sometimes I want to include only one class from a namespace rather than a whole namespace, like the example here I create a alias to that class with the using statement: using System; using System.Text; using Array = System.Collections.ArrayList; I often do this with generics so that I don't have to repeat the arguments: using LookupDictionary = System.Collections.Generic.Dictionary<string, int>; Now I want to accomplish the same with a generic type, while

用管了centos的童鞋们，到了一个没有ll命令的环境里，那是多么的痛苦，在baidu后，将实现方法记录如下方法一： echo "alias ll='ls -l'" >> ~/.bashrc && source ~/.bashrc 其实ll就是给ls -l命令做了一个别名。方法二：其实~/.bashrc文件中本来就有ll别名的代码，只是注释了而已，去掉注释即可 # some more ls aliases # alias ll='ls -l' # alias la='ls -A' # alias l='ls -CF' 改成 # some more ls aliases alias ll='ls -l' alias la='ls -A' alias l='ls -CF' 最后别忘了 source ~/.bashrc 来源： https://www.cnblogs.com/qpanda/p/11537311.html
