改了js ，结果ff和chrome好了，IE直接上传的时候会下载json
FF:
<body><pre>{"code":"Success","upload":1,"imgUrl":"http:\/\/localhost\/Public\/Uploads\/1.jpg"}</pre></body>Chrome:<body><pre style="word-wrap: break-word; white-space: pre-wrap;">{"code":"Success","upload":1,"imgUrl":"http:\/\/localhost\/Public\/Uploads\/1.jpg"}</pre></body> 最佳答案
