js script標(biāo)簽發(fā)送跨域請(qǐng)求，沒進(jìn)入回調(diào)是什么原因？

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

</script>
使用script 標(biāo)簽發(fā)送 這樣的一個(gè)請(qǐng)求
http://localhost:8080/cqpt/ueditor/exec?action=config&callback=bd__editor__e3zw61
Window對(duì)象上也掛載了著個(gè)方法

后臺(tái)請(qǐng)求接受成功，并返回json格式的數(shù)據(jù)，

但是前臺(tái)始終接受不到 返回的信息，這是什么情況？

使用的ueditor dojsonp的方法

返回的數(shù)據(jù)格式
