js script标签发送跨域请求，没进入回调是什么原因？

Question

<script 
type="text/javascript" 
defer="defer" 
src="http://localhost:8080/cqpt/ueditor/exec?action=config&callback=bd__editor__e3zw61"

</script>
使用script 标签发送 这样的一个请求
http://localhost:8080/cqpt/ueditor/exec?action=config&callback=bd__editor__e3zw61
Window对象上也挂载了着个方法

后台请求接受成功，并返回json格式的数据，

但是前台始终接受不到 返回的信息，这是什么情况？

使用的ueditor dojsonp的方法

返回的数据格式
{

"videoMaxSize":102400000,

"videoActionName":"uploadvideo",

"fileActionName":"uploadfile",

"fileManagerListPath":"/ueditor/jsp/upload/file/",

后端给你拼的字符串是啥，可以发出来吗，结构发出来就行让后端拼这样一个字符串给前端bd__editor__e3zw61(&nbsp; //你现在返回的对象 {巴啦巴拉一堆数据})你的请求中是带了bd__editor__e3zw61这个名字的，让后端给你拼下就行了
