我无法让我的数据表刷新。我有一个按钮，在它执行任何操作之前调用更新脚本和确认消息。这一切都很好，但我希望表刷新以获得新的结果。这是我到目前为止所拥有的。
function unapprove_link(data)
{
var str = $(this).attr('title');
var answer = confirm("Are you sure you want to UNAPPROVE this lead?");
if (!answer) return false;
$.post("actions/unapprove-lead.php",
{'lead_id': data},
function()
{
oTable.fnClearTable(0);
oTable.fnDraw();
}
);
}
这是我的完整代码：
$(document).ready(function()
{
/* // Unapprove Lead Alert
$('.unapprove').live('click', function() {
var str = $(this).attr('title');
var answer = confirm("Are you sure you want to UNAPPROVE this lead?");
oTable.fnDraw();
if (!answer) return false;
});
// Delete Lead Alert
$('.delete').live('click', function() {
var str = $(this).attr('title');
var answer = confirm("Are you sure you want to DELETE this lead?");
oTable.fnDraw();
if (!answer) return false;
});
*/
var anOpen = [];
var oTable = $('#example').dataTable
({
'bProcessing': true,

答案 0 :(得分：2)
调用 oTable.fnDraw（）会导致刷新。你正在做 $。发布，我会把它改成。$ ajax ，你也似乎没有对post操作返回的数据做任何事情。请记住，如果您期望它重新绑定数据，DataTable需要在响应中的某个位置使用oData对象。
事实上，数据表需要更多，你需要返回总数中的项目数，页面上显示的数字等。
