ajax中的 textStatus 报错为 parsererror。
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
<script src="js/jquery-1.8.0.min.js" type="text/javascript" charset="utf-8"></script>
<script src="js/jq.js" type="text/javascript" charset="utf-8"></script>
<script type="text/javascript">
$.ajax({
type: "GET",
url: "http://192.168.20.205:8080/platform/banner/bannerApi",
async:true,
dataType: "jsonp",
jsonp: "callback",
success:function(req){
console.log(req);
},
error:function(XMLHttpRequest, textStatus, errorThrown) {
alert(XMLHttpRequest.status);//400
alert(XMLHttpRequest.readyState);//2
alert(textStatus);//parsererror
}
});
</script>
</body>
</html>
求大神指点，之前真心没有碰到这种问题，获取其他方法也可以，坐等

题主，这个是跨域问题如果后端是你写的话你可以通过配置Cors,代码如下，希望能帮到你，对了spring要扫描到
/**
* Created by sunny on 2017/6/22.
*/
public class CorsConfig extends WebMvcConfigurerAdapter {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedOrigins("*")
.allowCredentials(true)
.allowedMethods("GET", "POST", "DELETE", "PUT")
.maxAge(3600);
}
@Override
public void addInterceptors(InterceptorRegistry registry) {
WebContentInterceptor webContentInterceptor = new WebContentInterceptor();
CacheControl nocache = CacheControl.noCache();
webContentInterceptor.addCacheMapping(nocache, "/**");
registry.addInterceptor(webContentInterceptor);
}
}
