AngularJS-监视指令的控制器范围

[英]AngularJS - watching the scope of directive's controller

原文 2014-05-23 15:14:09 6 1 javascript/ angularjs/ scope/ directive/ watch

I've built a plunker to test things out, but I must not be understanding some angular fundamentals. 我已经制作了一个测试用的插件，但是我一定不能理解一些棱角分明的基本原理。

Why is the directive's link function not able to watch a property (scope.featureAttributes) on the directive's controller's scope. 指令的链接函数为什么不能在指令的控制器作用域上监视属性（scope.featureAttributes）。
