$.ajax({
url:'http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx?op=getWeather',
type:'POST',
dataType: 'xml',
data:soap,
success:function(data){
alert('success');
},
error:function() {
alert('error');
}
});
});
});
</script>
结果是调了error
控制台信息是：XMLHttpRequest cannot load http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx?op=getWeather. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.
求大神指教！
------解决方案--------------------
跨域访问 ajax跨域访问
------解决方案--------------------
你这是跨域ajax吧！？
跨域只能使用JSONP来实现，或者通过服务器端获取
------解决方案--------------------
楼主可以将webservice取数据放到后台去处理，然后数据返回页面就可以了。后台调用不涉及跨域的问题。

------解决方案--------------------
跨域了。不可以，你可以在后台调用webservice ,然后前台ajax' 获取就行了。
------解决方案--------------------
jsonp估计不好搞，callback这边控制不了。还是写个servlet吧。severlet调用webservice，然后前台调用这个servelet就行了。 <script type="text/javascript">
$.ajax({
url:'http://localhost:8080/test/severlet/weather',
type:'GET',
dataType: 'json',
success:function(data){
alert(data.he);
},
error : function(e, text){
alert(e.status);
alert(text);
}
});
</script>
