Ajax的jsonp方式跨域获取数据的简单实例
jsonp的调用,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文件内容:getAInfo(["<input type='text' value='1222'/>"]) url: 'http://192.168.12.21:8080/systemr/danielinbiti.txt', dataType: 'jsonp',//跨域设置jsonp processData: false, jsonpCallback:'getAInfo',//与文件中的getAInfo对应 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(){// 需要在后台根据request获取callback,然后才callback(需要返回的json内容)的方式返回,getJSON是ajax的简化,只支持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>通过 AJAX 改变文本</h2></div> <button id="b01" type="button">改变内容01</button> <button id="b02" type="button">改变内容02getJSON</button> </body> </html>
