为什么我总是出现错误 undefined

你们的url是怎么写的

用的是哪个php文件呢能看一下源码么我用的是下载下来有一个serverjson.php

<script>
    $(document).ready(function () {
        $("#search").click(function () {
            /*利用jquery的ajax方法*/
            $.ajax({
                type:"GET",
                url:"serverjson.php?number="+$("#keyword").val(),
                dateType:"json",
                success:function (date) {
                    if(date.success) {
                            $("#searchResult").html(date.msg);
                        }else{
                            $("#searchResult").html("出现错误了"+date.msg);
                        }
                },
                error:function (jqXHR) {
                    alert("发生错误："+jqXHR.status);
                }
            });
        });
/*POST*/
        $("#save").click(function () {
            /*利用jquery的ajax方法*/
            $.ajax({
                type:"GET",
                url:"serverjson.php",

                date:{
                    name:$("#staffName").val(),
                    number:$("#staffNumber").val(),
                    sex:$("#staffSex").val(),
                    job:$("#staffJob").val(),
                },
                dateType:"json",
                success:function (date) {
                    if(date.success) {
                        $("#createResult").html(date.msg);
                    }else{
                        $("#createResult").html("出现错误了"+date.msg);
                    }
                },
                error:function (jqXHR) {
                    alert("发生错误："+jqXHR.status);
                }
            });
        });
    });


</script>
