angularjs - Angular ng 重复。循环遍历字符串中的字母

Question

我刚刚开始学习 Angular，无法解决 ng-repeat 的问题。

我想在单个 span 元素中显示输入的每个字母。我尝试了很多方法但没有任何效果。

Here's my code on codepen

这是您要找的吗？

每个字母将以不同的跨度打印。

solution 错误:ngRepeat:dupes

var app = angular.module('myApp', []);

app.controller('myCtrl', function($scope) {
  
});

.center-block {
  float: none;
}

input {
  margin: 20px;
}

span:hover {
  color: red;
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl" class="container">

  <div class="col-sm-10 center-block text-center">

    <input type="text" class="form-control" placeholder="Type to search..." ng-model="word" />

    <div ng-repeat="letter in word.split('') track by $index">
      <span> {{ letter }} </span>
    </div>
    <br/><br/> If you want to split the word by line <br/><br/>
    <div ng-repeat="letter in word.split(' ') track by $index">
      <span> {{ letter }} </span>
    </div>
  </div>
</div>
