我已经使用$ http.get api从数据库中检索了内容，并使用显示了每条记录ng-repeat。对于每条记录，我都有一个like and comment button.On on click on like button，im使用$ http.post插入一条记录，而我必须这样做change the name of button to "Liked"。问题是-单击任何一个记录如button时，所有其他记录（如button name）都将更改为Liked（包括）单击的按钮。

 <div ng-repeat="dat in details | filter : { product_name : textname} as results">          
        <p style="color:#4C97C8;" class="lead"><strong>{{dat.summary}}</strong></p>
        <ul>
          <li><b>Product:</b><span> {{dat.product_name}}</span></li>
          <li><b>Product Manager:</b><span> {{dat.first_name}} {{dat.last_name}}</span></li>
          <li><b>Description:</b><span> {{dat.description}}</span></li>
        </ul>
        <button style="background-color:#4C97C8;color:white;height:30px" class="btn buttonlike" ng-click="likebtn(dat.id,loginname)"><span class="glyphicon glyphicon-hand-right"></span><strong> {{ likebtnname }}</strong></button>   
        <button style="background-color:#4C97C8;color:white;height:30px" class="btn" ng-disabled="comment" ng-click="comment=true"><span class="glyphicon glyphicon-comment"></span><strong> Comment</strong></button>
        <div class="input-group " ng-show="comment">
            <input type="text" id="commentarea" name="commentarea" class="form-control" placeholder="comment" aria-describedby="basic-addon2" ng-model="takecomment">
            <span class="input-group-addon" id="basic-addon2" ng-click="takecomment=mycomment(dat.id,takecomment)"><span class="glyphicon glyphicon-send"></span></span>
        </div>
</div>

脚本/控制器中的likebtn（）方法是

$scope.likebtnname="Like";
$scope.likebtn = function(idvalue,namevalue) {

  var likereque = {
    method: 'POST',
    url: "https://url/Likes",
    headers: {
         "Content-Type": "application/json"
    },
    data: {
      "platform": {
       "record": { "idea_record": idvalue,
                   "liker": $scope.loginname
                 }
                 }
          }
  }
  $http(likereque).then(function(){
       alert("Liked Successfully");
       $scope.likebtnname="Liked"; },
     function(){alert("try again");});
  }

如何仅更改单击按钮的名称？

HTML：

<button style="background-color:#4C97C8;color:white;height:30px" class="btn buttonlike" ng-click="$parent.likebtn(dat.id,loginname, dat)"><span class="glyphicon glyphicon-hand-right"></span><strong> {{ dat.likebtnname||'Like' }}</strong></button>

Javascript：

$scope.likebtn = function(idvalue,namevalue,dat) {

  var likereque = {
    method: 'POST',
    url: "https://url/Likes",
    headers: {
         "Content-Type": "application/json"
    },
    data: {
      "platform": {
       "record": { "idea_record": idvalue,
                   "liker": $scope.loginname
                 }
                 }
          }
  }
  $http(likereque).then(function(){
       alert("Liked Successfully");
       dat.likebtnname="Liked"; },
     function(){alert("try again");});
  }
