how does angular.js edit specific parts of ng-repeat?
< hr > loops out a detail page with ng-repeat. After clicking the "Edit" button,  becomes editable < input >. 
 every module has id. I didn"t write it. Is it possible to directly manipulate the array? 
 I don"t know how to select a particular module, so I came to ask for help. Thank you 
 (as shown in the following figure, attached to the code) 
 
:
 
<div class="info-file" ng-repeat="item in info">
    <button class="btn" ng-click="toEdit()" ng-show="editPara"></button>
    <button class="btn" ng-click="add()" ng-hide="editPara"></button>
    <div class="form-group">
        <label class="label">:</label>
        <input class="input" name="name" ng-model="item.name" ng-hide="editPara">
        <span class="span info-span" ng-show="editPara">{{item.name}}</span>
    </div>
    <div class="form-group">
        <label class="label">:</label>
        <input class="input" name="age" ng-model="item.age" ng-hide="editPara">
        <span class="span info-span" ng-show="editPara">{{item.age}}</span>
    </div>
</div>
