scope

满脑子都是Angular/directive/scope/git
坑1: directive要用到controller里面的东西呢,有两种办法: 通过$scope.xxx来设置的,直接用xxx引用通过controller function 里面的 this.xxx 设置的,要通过controllerName.xxx引用爬爬墙,更健康:附AngularJS Directive文档坑2: git rebase和git merge有啥不同? 看看这:rebase的用法

Spring之作用域
Spring框架中对作用域的理解还是不够深入,经过学习,加深了作用域的理解,了解了其实现原理,总结本文. 其实作用域就是一个容器,针对于不同的应用场景,分为了单例.多例等. 1. 先看下作用域的应用场景,单例bean调用专属的构建bean的方法:原型bean则是直接构建bean:而自定义作用域的bean受自定义scope管理bean的创建: // Create bean instance. if (mbd.isSingleton()) { sharedInstance = getSingleto

maven中依赖的scope各个取值的含义
依赖范围控制哪些依赖在哪些 classpath 中可用,哪些依赖包含在一个应用中.让我们详细看一下每一种范围: 1.compile (编译范围) compile是默认的范围:如果没有提供一个范围,那该依赖的范围就是编译范围.编译范围依赖在所有的classpath 中可用,同时它们也会被打包. 2.provided (已提供范围) provided 依赖只有在当JDK 或者一个容器已提供该依赖之后才使用.例如, 如果你开发了一个web 应用,你可能在编译 classpath 中需要可用的Servl

如何在angular的scope中获取jquery事件执行后的变量
近日在完成angular的项目构建,当和easyui的datagrid结合时,我需要在datagrid的行选中onClickRow事件发生后获取行的id时,并传递给angular的模型变量.以便我的angular删除功能可以使用, 也许有人会问,为什么不用 <a ng-click="/xxxxx/"+row.id>删除</a> 经过我的测试,ng-click只会在dom生成时(编译or连接时)进行赋值,运行期间无法改变ng-click右边的值(如果有不同的结果的

javascript中的作用域scope介绍
在一般程序设计语言中,作用域是按块来划分的.即"变量定义在哪个块之内,这个块就是变量的有效范围". 而在javascript中,变量的作用域是按函数来划分的--变量在某个函数范围内有效.比如: var f = false; if(true) { var f = true; } //此时f位于if内,也就是块内,等价于还是全局范围内 alert(f) //所以,结果为true 再如下例: 复制代码代码如下: var f = false; function test() { var f

在Spring IOC容器中,由它管理的Java Bean具有作用范围. Spring1.x版本在Spring1.x版本中,标签有一个属性singleton,取值为布尔类型.如果将其设置为true,那么容器之中只存在一个该bean的共享实例,当其他的任何Bean依赖该bean时,只要请求的id与该bean的id相同,容器就将该bean的实例注入到请求的bean中.换言之,Spring IoC容器只是创建该bean的一个唯一实例,并把它存存贮在容器的单例缓存中,在需要时才将其取出.这样的受管be
