<div>
  <span ng-repeat="item in names">
       {{item}}<a class="btn btn-xs fa-remove" title="移除該項" ng-click="remove($index)"></a>
  </span>
  <a class="btn btn-sm btn-primary fa-search" ng-click="selectUser()">選擇</a>
</div>

在指令中，使用了獨立的scope，傳入的數(shù)據(jù)為使用逗號分割的字符串，我們使用了數(shù)組進行操作。

這里的技巧是在字符串和數(shù)組之間進行轉(zhuǎn)換。

這里使用了指令獨立的scope，使用了watch 對數(shù)組進行操作，需要注意的是如果監(jiān)控數(shù)組，需要使用深度監(jiān)控。

希望本文所述對大家AngularJS程序設(shè)計有所幫助。
