我对javascript / jquery几乎一无所知：
我有一个ajax调用，它返回在html表中格式化的条目，如下所示：
Stuff | Other stuff | delete stuff
------|----------------|-------------------------
value1| from database | delete this entry button
------|----------------|-------------------------
value2| from database | delete this entry button
上面的列说“删除内容＆＃39;有一个按钮，可以调用删除该条目的方法。我一直试图做的是在每行的末尾添加一个支票簿，然后发送一个数组到php进行多记录删除。
这是电话：
$('#menu-notifications').click(function() {
$.ajax({
type: 'GET',
url: '/admin/notifications/ajax_view_notifications/' + <?= $this->session->userdata('user_id'); ?>,
dataType: 'json',
cache: false,
success: function(data) {
$("#notifications-modal .modal-body table").find("tr:gt(0)").remove();
$.each(data, function(i, obj) {
$('#notifications-modal .modal-body table tr:last').after(
'<tr><td>' + htmlDecode(obj.message) + '</td>' +
'<td>' + obj.created_by + '</td>' +
'<td>' + obj.created_dt + '</td>' +
'<td><div class="btn-group">' +
'<a href="/admin/notifications/ajax_delete_notification/' + obj.id + '" class="btn btn-mini delete-notification" id="delete-notification" data-dismiss="modal"><i class="icon-remove"></i></a>' +
// here should be a checkbox to mark for deletion
'</div></td></tr>');
});
}
});
我已成功添加了复选框，但每次尝试<?=form_open();?>或打开另一个表单都会导致页面根本无法加载（控制台中没有任何内容）。
总结一下：我试图在每行的末尾添加一个复选框，我可以标记此chexbox，并将每个标记的复选框发送给方法。

您需要使用HTML array创建每个复选框，它的值将是元素ID，然后您需要一个操作（例如＆＃39; 全部删除＆＃39;按钮）使用Ajax将数据发送到PHP（无需任何形式）：
$('#menu-notifications').click(function() {
// Simpler: use getJSON
$.getJSON('/admin/notifications/ajax_view_notifications/' + <?= $this->session->userdata('user_id'); ?>)
// Clearner: use promises :)
.done(function(data) {
$("#notifications-modal .modal-body table").find("tr:gt(0)").remove();
$.each(data, function(i, obj) {
// Create a row
var row = $('<tr>');
// Crete cells
var cells =
'<td>' + htmlDecode(obj.message) + '</td>' +
'<td>' + obj.created_by + '</td>' +
'<td>' + obj.created_dt + '</td>' +
// We use this identified cell to create our delete functionality
'<td class="delete-row"></td>';
// Fill the row
row.append(cells);
// Create the delete button
var deleteButton = $('<a>', {
'href': '/admin/notifications/ajax_delete_notification/' + obj.id
,'class': 'btn btn-mini delete-notification'
// We can't have duplicate ids, so no ids here
// ,id: 'delete-notification'
,'data-dismiss':'modal'
,'html': '<i class="icon-remove"></i>'
});
// Crete the checkbox
var checkbox = $('input', {
'type': 'checkbox'
// We use an HTML array
,'name': 'rowsToDelete[]'
,'value': obj.id
});
// Append the button and the checkbox to the row
// I ignore the .btn-group on purpose
row.find('.delete-row')
.append(deleteButton)
.append(checkbox);
// We add the row to the DOM
$('#notifications-modal .modal-body table tr:last').append(row);
});
});
});
// To delete in group we use a different call, let's say, a 'Delete All' button
$('#delete-all').click(function() {
// We serialize the info of all the buttons
// Find all checkbox under the .delete-row class and serialize it
data = $('.delete-row').find(':checkbox').serialize();
// Send the data to PHP
$.post('/admin/notifications/ajax_delete_notification/delete_a_bunch', data)
// PHP would receive $_POST['rowsToDelete'] = [1, 2, 4, 20]
.done(function(data) {
alert('All selected rows were deleted');
})
.fail(function() {
alert('No rows deleted :/');
});
});
