Question

我正在做一个角度项目，我试图通过改变单选按钮来改变范围值和元素值。单击单选按钮1时，我从服务器获取值并将其保存在范围和元素中。当我单击单选按钮2时，必须删除所有范围和元素。清除了所有范围。但我的问题是当我编辑输入，并单击单选按钮2，跨度值和输入中的占位符都显示。不得显示跨度。这是我的代码。

的index.html

<div class="row">
    <div class="col" style="border: none;">
      <ion-item class="item-checkbox" style="border: none;">
        <label class="checkbox">
<input type="radio" id="oldChecked" ng-value="true" ng-model="oldChecked" ng-click="showName()">
            </label> Radio 1
      </ion-item>
    </div>
    <div class="col" style="border: none;">

      <ion-item class="item-checkbox" style="border: none;">
        <label class="checkbox">
                <input type="radio" id="newChecked" ng-value="true" ng-model="newChecked" ng-click="deleteName()">
            </label> Radio 2
      </ion-item>

    </div>
  </div>
   <div class="col" style="width: 100%;">
  <label class="item item-input item-floating-label" style="
  border-left:  none;border-right: none;border-top:none;">
  <span class="input-label" style="text-align: left;">Name 
  <font style="color: #ef473a;font-size: 14px;">*</font>
  </span>
  <input type="text" placeholder="Name" ng-model="pName"
   id="pName" name="pName" required>
 </label>
        </div>

controller.js

$scope.showName=function(){
$http.post(WebServer_URL, data, config)
  .success(function (data, status, headers, config) {
    var x2js = new X2JS();
    var jsonOutput = x2js.xml_str2json(data);
    var myPatient = JSON.parse(jsonOutput.string);
    $scope.pName = myPatient[0].Pt_Name;
    document.getElementById('pName').value = myPatient[0].Pt_Name;
}).error(function (data, status, header, config) {
    console.log("Status: " + status);
  });
}

    $scope.deleteName=function(){
    $scope.pName="";
    document.getElementById('pName').value = "";
 }

Here is the image showing span and placeholder

请帮我解决这个问题。先谢谢你们。

// radio buttons should have same ng-model
<input type="radio" value="oldChecked" ng-model="myOption" ng-click="showName()">
<input type="radio" value="newChecked" ng-model="myOption" ng-click="deleteName()">
<input type="text" id="pName" ng-model="pName" placeholder="Name">

  <script type="text/javascript">
    var app=angular.module("test",[]);
    app.controller("testCtrl",function($scope){
    $scope.showName=function(){
      $scope.pName = "Hello";
    }
    $scope.deleteName=function(){
     $scope.pName="";
    }
});

单击不同的单选按钮时更改角度$ scope值
