Question

I’m trying to download a CSV file to populate a graph with jQuery. Everything works fine in Firefox (12.0 win) but fails in IE (9.0 win) and Chrome (19.0 win.

The error thrown is just “error”. Nothing more.

I suspect it is due to a combination of mime-types and jQuery dataType
but I just can’t get it working. Does anyone have any suggestions?

My response from the server is this: (copied from Firefox)

Cache-Control:       private, s-maxage=0
Content-Disposition: attachment;filename=data.csv
Content-Type:        text/plain
Date:                Mon, 21 May 2012 12:53:36 GMT
Server:              Microsoft-IIS/7.5
Transfer-Encoding:   chunked
X-AspNet-Version:    4.0.30319
X-AspNetMvc-Version: 3.0
X-Powered-By:        ASP.NET

My jQuery snippet:

$.ajax({
    url: 'dummyurl',
    type: 'GET',
    dataType: 'text',
    success: function (data) {

        // process

    },
    error: function(jqXHR, textStatus, errorThrown){
        alert('An error occurred: ' + textStatus + ', ' + errorThrown);
    }
});

(Yes, I have googled and tried a lot of suggestions 🙂 )

Answer 1

I’ve finally found the solution. Here it is if someone googles for it:

Content-Type MUST include charset. If not, the request will just die with no further information in chrome.

Content-Type: text/plain; charset=utf-8
