织梦ajax跨域提交自定义表单和跨域验证码问题

A站(www.a.com),有个form表单,ajax提交到 B站(www.b.com),还附带个验证码

A站上的表单代码如下

  <script type="text/javascript" src="http://apps.bdimg.com/libs/jquery/1.6.4/jquery.min.js"></script>  <script>  function send(){      $.ajax({          cache:true,          type:"POST",          url:"http://www.b.com/plus/diy.php",          data:$('#diyform').serialize(),  		xhrFields:{withCredentials: true}, //ajax跨域提交需要  		crossDomain:true, //ajax跨域提交需要          success: function(data){              if(data=="success"){                  alert('发送成功!');              }else{                  alert('发送失败!');              }          }      });  }  </script>  <form action="" enctype="multipart/form-data" method="post" id="diyform">  	<input type="hidden" name="action" value="post" />  	<input type="hidden" name="diyid" value="2" />  	<input type="hidden" name="do" value="2" />  	<input type="hidden" name="dede_fields" value="name,text" />  	<input type="hidden" name="dede_fieldshash" value="c2be5bb5ec45d9d01ca9f60dc469b3fb" />  	<p>  		姓名:  		<input type='text' name='name' id='name' />  	</p>  	<p>  		验证码:  		<input type="text" name="validate"><img src="http://www.b.com/include/vdimgck.php" align="absmiddle" onclick="this.src='http://www.b.com/include/vdimgck.php?tag='+Math.random();" style="cursor:pointer;">  	</p>  	<div onclick="send()">提交</div>  </form>

1、提交到 http://www.b.com/plus/diy.php

2、验证码 http://www.b.com/include/vdimgck.php

3、ajax 跨域必需js代码

xhrFields:{withCredentials: true}, crossDomain:true,

B站上的 /plus/diy.php 文件上面加入

  header("Access-Control-Allow-Credentials:true");  header("Access-Control-Allow-Origin:http://www.a.com");
