请问小弟我使用加网jsapi接口,在微网站里无法执行$.ajax

<script><br />function ccd(evt){<br />        var url3 = "http://xxxxx/index.php?g=Wap&m=Card&a=ajax_fenxiang3";<br />        // var url2 = "{lanrain::U('Card/ajax_fenxiang',array('token'=>$_GET['token'],'wecha_id'=>$_GET['wecha_id']))}";<br />                 $.ajax({<br />				          type: "GET",<br />						  url: url3,<br />						  contentType: "application/json; charset=utf-8",<br />						  dataType: "json",<br />						  success: function (result) {<br />						     alert(111);<br />                          },<br />						  error: function (msg) {<br />								alert(333);<br />					      }<br />				 })<br />				<br /><br />}<br />	<br />var jiathis_config = {<br />    boldNum:0,<br />    siteNum:7,<br />    showClose:false,<br />    sm:"t163,kaixin001,renren,douban,tsina,tqq,tsohu",<br />    imageUrl:"http://v2.jiathis.com/code/images/r5.gif",<br />    imageWidth:26,<br />    marginTop:150,<br />    url:"http://www.jiathis.com",<br />    title:"自定义TITLE #微博话题#",<br />    summary:"分享的文本摘要",<br />    pic:"自定义分享的图片连接地址",<br />    data_track_clickback:true,<br />    evt: {"share":"ccd"}<br />}<br /></script>
