[英]HTML DOM table removing/deleting selected row/rows
我有以下代碼。 我試圖包括一個刪除按鈕以刪除所選的一行或多行...在代碼中包括所選內容以及刪除功能，但是我不知道如何獲取所選的行並將其傳遞給該功能以刪除它...代碼中包含的一個按鈕應該足夠了，但是如果您知道如何在每一行中都包含一個刪除按鈕“ X”，請告訴我...
這是示例頁面： http : //knightfire66.bplaced.net/testcode.php ，這是其他一些代碼，但不適用於我的代碼： http : //jsfiddle.net/Z22NU/12/

這就是我要做的：
首先，我們在html表的每一行中添加一個帶有刪除按鈕的td
然后，我們可以將偵聽器附加到#table元素（ id="table"的元素）上。 該偵聽器偵聽具有delete-table, when one is clicked, we take the button and find the closest類的#table后代的delete-table, when one is clicked, we take the button and find the closest tr`（在DOM樹上），然后將其刪除。
$('#table').on('click','.delete-row',function(){ $(this).closest('tr').remove(); // $(this) is the button });
td {border: 1px #DDD solid; padding: 5px; cursor: pointer;} .selected { background-color: brown; color: #FFF; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <table id="table"> <tr> <td>1 Ferrari F138</td> <td>1 000€</td> <td>1 200€</td> <td>Model monopostu stajne Scuderia Ferrari pre sezónu 2013</td> <td>1</td> <td>F138</td> <td>Klik pre detaily</td> <td><button class="delete-row">Delete</button></td> </tr> <tr> <td>2 Ferrari F138</td> <td>1 000€</td> <td>1 200€</td> <td>Model monopostu stajne Scuderia Ferrari pre sezónu 2013</td> <td>1</td> <td>F138</td> <td>Klik pre detaily</td> <td><button class="delete-row">Delete</button></td> </tr> <tr> <td>3 Ferrari F138</td> <td>1 000€</td> <td>1 200€</td> <td>Model monopostu stajne Scuderia Ferrari pre sezónu 2013</td> <td>1</td> <td>F138</td> <td>Klik pre detaily</td> <td><button class="delete-row">Delete</button></td> </tr> </table>
這是我過去做過類似事情的一個例子...
基本上我以編程方式向每行添加一個刪除按鈕：
// ADD A DELETE BUTTON ON EACH ROW
$('td').each(function(i, val){
$('td').eq(i).prepend('<span class="deleteButton">Delete</span>')
});
然后，只要單擊這些按鈕之一，我們就會刪除相應的（父）行：
// WHEN DELETE BUTTON IS CLICKED REMOVE THE TABLE ROW
$(document).on('mousedown', '.deleteButton', function(){
$('tr').eq($('.deleteButton').index(this)).remove();
})
這是工作演示 。
