<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("出現錯誤了"+date.msg);
????????????????????????}
????????????????},
????????????????error:function?(jqXHR)?{
????????????????????alert("發生錯誤："+jqXHR.status);
????????????????}
????????????});
????????});
/*POST*/
????????$("#save").click(function?()?{
????????????/*利用jquery的ajax方法*/
????????????$.ajax({
????????????????type:"GET",
????????????????url:"serverjson.php",
????????????????date:{
????????????????????name:$("#staffName").val(),

可以省略的，但是做開發的時候要嚴格遵循，最好寫上。

header("Content-Type: text/plain;charset=utf-8"); 這個是設置頭部信息的，返回來是text文本text/plain；
header("Content-Type: application/json;charset=utf-8"); 同理，返回來是json字符串application/json;
2017-02-05
header("Content-Type: text/plain;charset=utf-8");?
//header("Content-Type: application/json;charset=utf-8");?
這兩句什么意思??？？
?$jsonp?=?$_GET["callback"]; ?
