bootstrap-angular.js 评论按顺序排序

Question

我想通过在输入部分输入日期、作者和评级以特定顺序显示 cmets。它们还应该能够按降序排序，例如，如果输入 -date。我被卡住了。

Comments sorting

这是我的代码。

                <ul class="list-unstyled" ng-repeat="comment in dishDetailCtrl.dish.comments | orderBy:dishDetailCtrl.sortBy">
                  <li><blockquote>
                      <h4>{{comment.rating}} Stars</h4>
                      <h4>{{comment.comment}}</h4>
                      <footer>
                          {{comment.author}}, {{comment.date | date:mediumDate}}
                      </footer>
                  </blockquote></li>
              </ul>

<script>

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

    app.controller('dishDetailController', function() {

        var dish={
                      name:'Uthapizza',

<blockquote ng-repeat="comment in dishCtrl.dish.comments | orderBy:userInput">

     <footer>{{comment.author}} {{comment.date | date:'medium'}}</footer>
 </blockquote>

Answer 3

上面的代码似乎可以正常工作，我认为您错过了在 SortBy 输入中错误地写入 ng-model 变量名。

应该是

ng-model="dishDetailCtrl.sortBy"

而不是

ng-model="sortBy"

HTML

<div ng-controller="dishDetailController as dishDetailCtrl">
  Sort By <input type="text" ng-model="dishDetailCtrl.sortBy">
  <ul class="list-unstyled" ng-repeat="comment in dishDetailCtrl.dish.comments | orderBy:dishDetailCtrl.sortBy">
    <li>
      <blockquote>
        <h4>{{comment.rating}} Stars</h4>
        <h4>{{comment.comment}}</h4>
        <footer>
          {{comment.author}}, {{comment.date | date:mediumDate}}
        </footer>
      </blockquote>
    </li>
  </ul>
</div>
