Javascript 这是什么代码？？？{{phrase.addAdministrator}

我遇到过一个包含这种类型代码的应用程序，我不明白{{phrase.addAdministrator}}是什么，它来自哪里

<section class="content" ng-show="views.list"><a ng-click="changeView('add')" class="floatRTL btn btn-success btn-flat pull-right marginBottom15">{{phrase.addAdministrator}}</a>  
  <div class="box col-xs-12">
      <div class="box-header">
          <h3 class="box-title">{{phrase.listAdministrators}}</h3>
          <div class="box-tools">
              <div class="input-group">
                  <input type="text" name="table_search" ng-model="searchText" class="form-control input-sm pull-right" style="width: 150px;" placeholder="{{phrase.Search}}">
                  <div class="input-group-btn">
                      <button class="btn btn-sm btn-default"><i class="fa fa-search"></i></button>
                  </div>
              </div>
          </div>
      </div>
      <div class="box-body table-responsive">
          <table class="table table-hover">
              <tbody><tr>
                  <th>{{phrase.ID}}</th>
                  <th>{{phrase.name}}</th>

              </tr>
              <tr ng-repeat="admin in admins | filter:searchText">
                  <td>{{admin.id}}</td>
                  <td>{{admin.fullName}}</td>

              </tr>
              <tr ng-show="!admins.length"><td class="noTableData" colspan="5">No administrators</td></tr>
          </tbody></table>
      </div>
  </div>
</section>

<section class="content" ng-show="views.add">

          </div>
        </div>
      </form>
    </div>
  </div>
</section>

如果你能解释一下这一切意味着什么，我怎样才能创建这样的代码

任何帮助都将不胜感激

在这种情况下，这些都是表达。还有其他使用大括号{{}的模板引擎，比如Mustach，但是在您提供的代码中，它的AngularJs。

看起来像AngularJs的示例：ng类，ng模型，{}是表达式…它们是模板引擎的占位符，用于交换afaics传递给它的值。堆栈不是what is this或how to site。你当然可以研究一下。哦，你有吗你花了多长时间，10秒就放弃了？所以我需要学习angularJs来创造这些权利？问问下面给你答案的人。这超出了评论的范围。现在我们无法控制了。
