看了半天，没有弄明白你要表达的意思，菜单栏的id传递到哪？
就是把item.cat_id 传递到goods.php里？？
$.get(
'goods.php',
qjbl:qjbl,//这个方法应该是这样的才对吧
function(msg) {
$(msg)
.each(
function(i,
$(function () {
$.get('category.php', 'parent_id=0', function (msg) {
$(msg).each(function (i, item) {
//cat_id放到自定义属性里面
$('#menu>ul').append('<li catid="' + item.cat_id + '">' + item.cat_name + '</li>');
});
}, 'json');
$('#menu').bind('click', function (e) {
var target = e.target;//得到点击对象
if (target.tagName != 'LI') return;//点击的不是li对象退出，就是上面得到的li对象
$('#content').empty();
$.get('goods.php', { cat_id: target.getAttribute('catid') },//////////////////
function (msg) {
$(msg).each(function (i, item) {
$('#content').append('<div style="float:left;width:20%;margin:5%;text-align:center;"><img src="' + item.goods_img + '"/>' + '<p>' + item.goods_name + '</p></div>');
