jsonp的調用，今天碰到了，正好整理了一下。
<!DOCTYPE html><html><head><script src="http://libs.baidu.com/jquery/1.9.1/jquery.min.js"></script> <script type="text/javascript">$(document).ready(function(){ $("#b01").click(function(){ $.ajax({//danielinbiti.txt檔案內容：getAInfo(["<input type='text' value='1222'/>"]) url: 'http://192.168.12.21:8080/systemr/danielinbiti.txt', dataType: 'jsonp',//跨網域設定jsonp processData: false, jsonpCallback:'getAInfo',//與檔案中的getAInfo對應 type: 'get', success: function(data) { $("#myDiv").html(data); }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert('error'); alert(XMLHttpRequest.status); alert(XMLHttpRequest.readyState); alert(textStatus); } }); }); $("#b02").click(function(){// 需要在後台根據request擷取callback，然後才callback(需要返回的json內容)的方式返回，getJSON是ajax的簡化，只支援json格式 $.getJSON("http://192.168.12.21:8080/systemr/b.do?jsoncallback=?",function(result){ $("#myDiv").html(result); }); });});</script></head><body><div id="myDiv"><h2>通過 AJAX 改變文本</h2></div><button id="b01" type="button">改變內容01</button><button id="b02" type="button">改變內容02getJSON</button></body></html>
