javascript - AngularJS 基于 JSON 记录过滤数据

Question

我有一个 JSON 文件，想要打印 <divs>基于餐厅的地址，但我想根据“r.Address”字段对它们进行分组。与所有带有“地址”的记录一样，德里应该首先显示，然后是“昌迪加尔”的所有记录，依此类推。我怎样才能做到这一点？

以下是我的一些代码

                    <a href="#" ng-repeat="r in resturant" id="rest-list-f" class="offVal">
                        <div class="col-md-6 col-centered form-planner-inner">
                            <span class="form-text">{{ r.Name }}</span><br>
                            <address><span class="glyphicon glyphicon-map-marker" aria-hidden="true"></span> &nbsp;{{ r.Address }}</address>
                            <img class="img-responsive" src="{{ r.Image }}" alt="{{ r.Name }} Image"><br>
                            <hr/>
                            <table class="eventActive">
                                <caption><strong><center><a href="#">Click To Read Reviews</a></center></strong></caption>
                                <tr>
                                    <td><span class="glyphicon glyphicon-cutlery" aria-hidden="true"></span> &nbsp;{{ r.Type }}</td>
                                    <td><span class="glyphicon glyphicon-time" aria-hidden="true"></span> &nbsp;{{ r.Hours }}</td>
                                </tr>
                            </table>
                        </div>
                    </a>

这是我的 JSON 代码

   {
  "records": [
    {
      "Name": "Sagar Ratna",
      "Image": "./images/sr.jpg",
      "Address": "Mohali",
      "Type": "South Indian",
      "Hours" : "10:00-23:30"
    },
    {
      "Name": "The Night Factory",
      "Image": "./images/nf.jpg",
      "Address": "Chandigarh",
      "Type": "Chinese",
      "Hours" : "24/7"
    },
    {
      "Name": "Whistling Duck",
      "Image": "./images/ed.jpg",
      "Address": "Rajpura",
      "Type": "Chinese",
      "Hours" : "11:30-23:30"
    },
    {
      "Name": "Uncle Jack's",
      "Image": "./images/uj.jpg",
      "Address": "Mohali",
      "Type": "Pizza",
      "Hours" : "10:00-22:30"
    },
    {
      "Name": "Corner Griller",
      "Image": "./images/cg.jpg",
      "Address": "Rajpura",
      "Type": "North Indian",
      "Hours" : "11:00-23:30"
    },    {
      "Name": "Starbucks",
      "Image": "./images/st.jpg",
      "Address": "Delhi",
      "Type": "Coffee",
      "Hours" : "24/7"
    }
  ]
}

这是我想要的输出:

<div> Restaurant Name, Address: Delhi </div>
<div> Restaurant Name, Address: Mohali </div>
<div> Restaurant Name, Address: Mohali </div>
<div> Restaurant Name, Address: Rajpura </div>  
<div> Restaurant Name, Address: Rajpura </div>
<div> Restaurant Name, Address: Rajpura </div>
<div> Restaurant Name, Address: Chandigarh </div>

我对你的代码做了一些更改。请尝试这个。

JSON

  $scope.Restaurents =  {
  "records": [
    {
      "Name": "Sagar Ratna",
      "Image": "./images/sr.jpg",
      "Address": "Mohali",
      "Type": "South Indian",
      "Hours" : "10:00-23:30"
    },
    {
      "Name": "The Night Factory",
      "Image": "./images/nf.jpg",
      "Address": "Chandigarh",
      "Type": "Chinese",
      "Hours" : "24/7"
    },
    {
      "Name": "Whistling Duck",
      "Image": "./images/ed.jpg",
      "Address": "Rajpura",
      "Type": "Chinese",
      "Hours" : "11:30-23:30"
    },
    {
      "Name": "Uncle Jack's",
      "Image": "./images/uj.jpg",
      "Address": "Mohali",
      "Type": "Pizza",
      "Hours" : "10:00-22:30"
    },
    {
      "Name": "Corner Griller",
      "Image": "./images/cg.jpg",
      "Address": "Rajpura",
      "Type": "North Indian",
      "Hours" : "11:00-23:30"
    },    {
      "Name": "Starbucks",
      "Image": "./images/st.jpg",
      "Address": "Delhi",
      "Type": "Coffee",
      "Hours" : "24/7"
    }
  ]
}

HTML

<a href="#" ng-repeat="r in Restaurents.records | orderBy:'Address'" id="rest-list-f" class="offVal">
                <div class="col-md-6 col-centered form-planner-inner">
                    <span class="form-text">{{ r.Name }}</span><br>
                    <address><span class="glyphicon glyphicon-map-marker" aria-hidden="true"></span> &nbsp;{{ r.Address }}</address>
                    <img class="img-responsive" src="{{ r.Image }}" alt="{{ r.Name }} Image"><br>
                    <hr />
                    <table class="eventActive">
                        <caption><strong><center><a href="#">Click To Read Reviews</a></center></strong></caption>
                        <tr>
                            <td><span class="glyphicon glyphicon-cutlery" aria-hidden="true"></span> &nbsp;{{ r.Type }}</td>
                            <td><span class="glyphicon glyphicon-time" aria-hidden="true"></span> &nbsp;{{ r.Hours }}</td>
                        </tr>
                    </table>
                </div>
            </a>

希望能有所帮助。您还可以在 Controller 端处理时对 json 数组进行分组。
