单击后动态更改按钮上的名称 [英] Dynamically changing the name on button after click

问题描述

我已经使用$ http.get api从数据库中检索了内容，并使用 ng-repeat 显示了每条记录.对于每条记录，我都有一个 like和comment按钮.在单击like按钮时，im使用$ http.post插入一条记录，并且我必须将按钮的名称更改为喜欢" .问题是-单击任何类似按钮的记录后，所有其他记录(例如按钮名称)都将更改为喜欢"，包括单击的按钮.

I have retrieving the contents from database using $http.get api and displaying each record using ng-repeat. For each record i have a like and comment button. On clicking on like button, i m inserting a record using $http.post and i have to change the name of button to "Liked".The problem is- on clicking any one of the record like button, all other records like button name changes to Liked including clicked button.

 <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

likebtn() method inside script/controller is

$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?

How can i change the name of clicked button only?

推荐答案

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");});
  }
