帮帮忙，为什么我的structs2 jquery ajax去做登录可是后台接收不到数据，这是关于毕业设计的，时间紧迫
这是jq代码
$(function() {
// alert("test");
$("#su").click(
function() {
// alert("test");
if ($("#username").val() != "" && $("#passw").val() != "") {
alert($("#username").val());
alert($("#passw").val());
$.ajax({
url : "user/logintest.action", //"user/logintest.action",
date : {
"username" : $("#username").val(),
"passw" : $("#passw").val(),
//'test' : "whl",
},
dataType : "json",
type : "post",
//async : false,
success : function(ok) {
if (ok) {
// alert("是否存在");
$("#login").css("display", "none");
$("#haslogin").css("display", "inline").html(
$("#email").val());
close_login();
} else {
$(".info").addClass(
"Validform_wrong Validform_checktip")
.html("用户名或密码错误！");
}
}
});
}
})
