Question

我正在试图展示95岁的＃34; [6] Peter＆＃34;文本框中的值是hide.But它应显示<button ng-click="show_id(friend.id)">get my id</button>的时间点击。名称应为ng-model="name"，年龄为ng-model="age"。

angular.module("my_app",[])
.controller("my_ctr",function($scope){

    $scope.show_id=function(index){
        alert(index);
    }
})

<body ng-app="my_app" ng-controller="my_ctr">
    <div ng-init="friends = [

  ]">
    I have {{friends.length}} friends. They are:

    <ul>
      <li  ng-repeat="friend in friends.slice().reverse() ">
        [{{friend.id}}] {{friend.name}} who is {{friend.age}} years old.
        <input type="text" ng-model="name" ng-hide="true">
          <input type="text" ng-model="age" ng-hide="true">
          <input type="text" ng-model="gender" ng-hide="true">
        <button ng-click="show_id(friend.id)">get my id</button>       
      </li>

    </ul>
  </div>
</body>
</html>

但是这段代码无效。

试试这个：

  <li  ng-repeat="friend in friends.slice().reverse() ">
    [{{friend.id}}] {{friend.name}} who is {{friend.age}} years old.
    <input type="text" ng-model="friend.name" ng-show="showItem">
      <input type="text" ng-model="friend.age" ng-show="showItem">
      <input type="text" ng-model="friend.gender" ng-show="showItem">
    <button ng-click="showItem=true">get my id</button>       
  </li>
