以前刪除具有較小索引的對象時，刪除對象失敗。

我想創建代表程序的多層對象，你可以看到我在做什麼這裏http://codepen.io/Irish1/pen/lbjdw 以前刪除具有較小索引的對象時，刪除對象失敗。

說我加3周，每3天每3屆。我嘗試之前，我可以，只要我不刪除這些對象移除說，第二天和第三天

去除這裏的會話是代碼

HTML

<div ng-app="trainercompare"> 

<div ng-controller="programsController"> 
    <form ng-submit="addProgram()" name='form' novalidate> 

     <p> 
a program 
     </p> 

     <button type ="button" ng-click="addWeek()"> add week</button> 

     <!-- create weeks --> 
     <div ng-repeat="week in program.weeks" ng-init="weekindex = $index"> 

      <p> 
      a week 
      </p> 

      <!-- create days --> 
      <div ng-repeat="day in week.days" ng-init="dayindex = $index"> 

       <p> 
       a day

你說，你是不是能夠只要它的前一個兄弟犯規存在刪除某些對象之前？ – ProllyGeek

如果我刪除一個對象，我不能刪除後續兄弟姐妹的子女。我相信可以刪除兄弟姐妹。 – Ir1sh

謝謝你的回答，我現在正在翻閱它，雖然它適用於添加和刪除幾周，但我很難說它是否會幫助我目前遇到的問題，因爲它與我之前的情況截然不同接近它。我會試着弄清楚，非常感謝你 – Ir1sh

這是一個很大的幫助，並沒有像我期待的那樣難以理解，它打破了我的添加方法，除非我刪除所有內容並重新開始。他們在我的問題中也很詳細，如果您有任何建議，那也會很好。 – Ir1sh
