我正在使用jquery对页面执行$ .post，问题是这个帖子在被解雇时执行了两次，我试图在IE和firefox中运行页面，结果是一样的，并且使用萤火虫表明该请求已经提交了两次。
我需要你的帮助，提前谢谢。 这是代码：
jQuery().ready(function() {
//Reply buttons binding live event
$(".ticketButton").live('click', function(e) {
e.preventDefault();
//build dialog with id & title
$( "#msgs-form:ui-dialog" ).dialog( "destroy" );
var ticket_ID= $(this).attr("title");
var ticket_title= $(this).attr("msgTitle");
$("#msgs-dialog").attr("title", ticket_title);
//fetch data from the server to fill dialog content
$.post("server_processing_tickets_response.php", {'getTickets' : ticket_ID},
function(data){
var div_data;
//build div's of classes .ticket-1 and ticket-0 from the returned json object
$.each(data.tickets_data, function(i, tickets_data)
{
div_data += "<div class='ticket-0'><span>" + tickets_data.content + "</span></div>";
});
$(div_data).appendTo("#ticketsWrap");
}, "json");
$("#msgs-form #ticketID").attr("value", ticket_ID);
$( "#msgs-dialog" ).dialog({
autoOpen: false,
title: ticket_title,
height: 'auto',
width: 460,
show: "fade",
hide: "fade",
modal: true,
resizable: false,
buttons: false,
close: resetDialog()
});
$( "#msgs-dialog" ).dialog( "open" );
});
function resetDialog(){
$("#ticketsWrap").empty();
}
}
感谢您的快速回复！ 这是我正在使用的完整javascript代码：

它与请求标头有关吗？ 这是我提交表单后从firebug获得的标题： 响应标题 Date Sat，09 Jul 2011 13:29:51 GMT 服务器Apache / 2.2.17（Win32）PHP / 5.3.5 X-Powered-By PHP / 5.3.5 Expires Thu，1981年11月19日08:52:00 GMT Cache-Control no-store，no-cache，must-revalidate，post-check = 0，pre-check = 0 Pragma no-cache 内容长度24 保持活动超时= 5，最大值= 84 连接保持活跃 内容类型文本/ html 请求标题 主持人127.0.0.1:8888 User-Agent Mozilla / 5.0（Windows NT 6.1; rv：2.0.1）Gecko / 20100101 Firefox / 4.0.1 接受application / json，text / javascript， / ; Q = 0.01 Accept-Language en-us，en; q = 0.5 Accept-Encoding gzip，deflate Accept-Charset ISO-8859-1，utf-8; q = 0.7，*; q = 0.7 保持活力115 连接保持活着 Content-Type application / x-www-form-urlencoded;字符集= UTF-8 X-Requested-With XMLHttpRequest 参考者http://127.0.0.1:8888/Lightc-tables/msgs.php 内容长度41 Cookie PHPSESSID = ku8e6o3h2bl27ltofkir58a626
并且在此标题之后也重复了具有不同Expires的相同标题..
答案 0 :(得分：1)
你需要使用一些小触发器;）
$(".ticketbutton").unbind("click");
$(".ticketbutton").unbind("live");
$(".ticketbutton").die();
