IE下使用ajaxFileUpload.js上传图片成功后，弹出打开/另存为窗口

[qq2St]

$.ajaxFileUpload({
url : '/a/b',
type:'post',
secureuri : false,
fileElementId : 'res_add_edit_attachment',
dataType : 'jsonp',
data: {//加入的文本参数
"Id": uuid
},
success : function(data) {
if(data.data == "操作成功"){
alert("操作成功");
},
error : function(data, e) {
alert(data.data);
//alert('上传失败！');
}
});

上传成功后，在IE下会弹出保存窗口，打开是后台返回的“操作成功”字段
无论把dataType 修改成text,script,json等格式都一样
有什么解决方法或者替代方案没？


ps:后台必需要返回“操作成功”字段。

实在不行就输出页面的头文件格式设置为text/plain 然后收到数据之后使用 data= JSON.parse(data);//将文本转为json之后再判断

在你的服务器端文件接收完成后输出的响应头设置为Content-type:text/json

[liutao5121]

已经修正该问题答案：；楼上的都不行 这个我自己亲测：将响应头设置为Content-type:text/html。

good，困扰好久的问题解决了，谢谢大神！

[xielongxin]

我也遇到了同样的问题，请问楼主是怎么解决的呀，谢谢！

[eric_2030]

怎么我的HTML头文件是Content-type:text/html，也不行呢？求大神指教?

[insomniaAtNight]

ie不兼容用不了

[ft2120030]

dataType用text，后台返回ISO-8859-1字符串就能解决弹框和乱码问题，java参考： private String formatAjaxUploadReturn(String msg) throws Exception { return new String(msg.getBytes("UTF-8"),"ISO-8859-1"); }

。并且我改成Content-type:text/plain，也不行!!!

[quote=引用 4 楼 u013193309 的回复:] 大神，你们怎么解决的这个问题，改content-type我已经试过了，没好使。

[captainnx]

content-type设置成text/json就可以了,亲测~

上面js代码，ajaxfileUpload.js兼容ie7、8、9、10、11、firefox、chrome等浏览器

我先试试喽上的兼容js，先试试，再评价。

还是不行啊。
