jquery – IE9中的AJAX Jsonp调用失败

我有以下代码

$.ajax({ type: 'POST',url: 'index.jsp',data: 'id=111',dataType: 'jsonp',success:  function(data) {
            alert(data.result);
                },error: function( err1,err2,err3 )
        {
              alert('Error:' + err3 )
        }
            });

我将返回响应作为使用json参数生成的回调参数.像这样

jQuery16105097715278461496_1314674056493({"result" : "success"})

这在FF中绝对正常.在IE 9中,它转到错误功能并显示

"Error: jQuery16105097715278461496_1314674056493 was not called" .

当我看到F12.我看到一个警告说.

SEC7112: Script from http://otherdomain.com
index.jsp?callback=jQuery16105097715278461496_1314674056493
&eid=111&_=1314674056493 
was blocked due to mime type mismatch

解决方法

尝试添加contentType

$.ajax({
     type: 'POST',data: {id:'111'},contentType: "application/json; charset=utf-8",success:  function(data) {
       alert(data.result);
     },err3 )
     {
       alert('Error:' + err3.status );
       alert(err1.responseText);
        }
 });
