我有一個嵌套JSON構造這樣刪除(拼接)從嵌套JSON的元素:如何使用AngularJS
[{
"phone_id" : "1",
"phone_name" : "nokia",
"phone_img" : "/src/imgs/nokia.jpg",
"phone_comments" :
[
{
"comment_id" : "1",
"user_id" : "32508",
"comment_date" : "2001-02-01",
"user_comment" : "This was the first phone that was rock solid from Nokia"
},
{
"comment_id" : "2",
"user_id" : "32518",
"comment_date" : "2001-02-02",
"user_comment" : "Great phone before the smartphone age"
},
{
"comment_id" : "3",
"user_id" : "22550",
"comment_date" : "2002-04-01",
"user_comment" : "Reminds me of my grandpa's phone"
},
{
"comment_id" : "4",
"user_id" : "31099",
"comment_date" : "2001-05-11",
"user_comment" : "It was a crappy one!"
}
]
}
]
顯示器部件(作品) - 我米能夠在第一表格中顯示電話圖像列和ng-click我加載第二欄與手機信息與評論。這工作非常好。
刪除(不工作) - 我有刪除評論的問題。我不想刪除整個電話對象,而只是刪除特定的評論。我可以通過像???
remove(comment, $index)
然後有一個功能,執行以下操作?
$scope.remove = function (index, comments) {
alert(comments.user_comment + index);
$scope.comments.splice(index, 1);
}
作爲參考,HTML看起來像:
<div ng-app="angularJSApp">
<div ng-controller="PhoneCtrl">
<br/><br/><br/>
<table width="100%" border="1">
<tr ng-repeat="ph in phones">
<td width="20%"><a href="#" ng-click="showComments = ! showComments"><img width="50%" ng-src="{{ph.phone_img}}"></a></td>
<td>
<p>Phone Id: {{ph.phone_id}}</p>
<p>Phone Name: {{ph.phone_name}}</p>
<p>Number of comments: {{ph.phone_comments.length}}</p>
<div class="shComments" ng-show="showComments">
<p>Search: <input ng-model="query"></p>
<table border="1" width="100%">
<thead>
<tr>
<th><a href="" ng-click="predicate = 'comment_id'; reverse = !reverse">Id</a></th>
<th><a href="" ng-click="predicate = 'user_comment'; reverse = false">Comment</a>
(<a href="" ng-click="predicate = '-user_comment'; reverse = false">^</a>)
</th>
<th><a href="" ng-click="predicate = 'comment_date'; reverse = !reverse">Date</a></th>
<th><a href="" ng-click="predicate = 'user_id'; reverse = !reverse">User</th>
<th></th>
</tr>
</thead>
<tbody>
<tr ng-repeat="comment in ph.phone_comments | filter:query | orderBy:predicate:reverse">
<th>{{comment.comment_id}}
<th>{{comment.user_comment}}</th>
<th>{{comment.comment_date}}</th>
<th>{{comment.user_id}}</th>
<th><button ng-click="remove($index, comment)">Remove Comment</button>
</tr>
</tbody>
</table>
</div>
</td>
</tr>
</table>
</div>
</div>
P.S:我一直在嘗試AngularJS和我,m具有尋找解決方案,盡我所能後問這個。謝謝你的幫助。
感謝您的回覆。但是,這對我不起作用。你可以看看http://plnkr.co/edit/gcA5MgshB9wriGM9sKEF?p=preview –
它不起作用的原因是因爲你需要兩個索引,一個用於手機,一個用於評論手機數據結構化。我編輯了我的答案給你一個想法。 – rdodev
