這裏是我的完整代碼：當我取消刪除時，爲什麼不勾選複選框？

問題部分是：（在PHP）
echo '<td><input type="checkbox" id="selected" value="' . $id . '" name="selected[]" /></td>';
（在HTML）
<input type="button" id="cancelDelete" class="dialogButton cancelButton" name="cancelDelete" value="Cancel" />
（jQuery中）
$('#cancelDelete').click(function(){
$("checkbox[name='selected[]']").attr('checked', false);
});
何我是否確保在出現的彈出窗口中單擊取消按鈕時取消選中複選框？ I.e.如何確保名爲selected []的複選框（[]是用於PHP的目的）在單擊#cancelDelete時未被選中？
如果您有jQuery的問題，你爲什麼要張貼了很多PHP的？請點擊''''按鈕並創建一個[mcve] – mplungjan
@mplungjan突出顯示問題部分。還包括整個代碼，如果有什麼東西可以逃脫我的注意力，這對解決問題是有效的。 –
