如何使用jQuery获取附件文件内容

Question

在get我的响应上content-disposition: attachment;filename=f.csv,我需要在页面上下载此文件的内容.
在$.ajax请求我有一个错误.如何使用jQuery ajax(或get)获取文件内容？
UPD

error: function( jqXHR, textStatus, errorThrown ) {
  console.log( jqXHR, textStatus, errorThrown );
}  

得到

Object {
    ...
    readyState 0
    responseText ""
    status 0
    statusText "error"
}, error,

我找到了一个jquery.fileDownload插件,但它显示了带有保存或打开对话框的浏览器窗口,如下所示:
但我需要获取文件内容.
我不需要在电脑上下载文件.

完整代码列表:

$.ajax( {
    url: link,
    crossDomain: true,
    dataType: "text",
    success: function( data, textStatus, jqXHR ) {
        alert( data );
    },
    error: function( jqXHR, textStatus, errorThrown ) {
        console.log( jqXHR, textStatus, errorThrown );
    }
} );  

文件由另一个服务生成,我无法更改它.

首先,我试图json从另一个域获取数据,如下所示:

$.ajax( {
    url: link,
    async: true,
    cache: true,
    dataType: "jsonp",
    crossDomain: true,
    type: "GET",
    jsonp: "finance_charts_json_callback",
    jsonpCallback: "finance_charts_json_callback",
    error: function( jqXHR, textStatus, errorThrown ) {
        console.log( jqXHR, textStatus, errorThrown );
    },
    success: function( data, textStatus, jqXHR ) {
        console.log( data );
    }
} );  

link 好像 http://chartapi.finance.yahoo.com/instrument/1.0/a/chartdata;type=quote;ys=2012;yz=2;ts=1234567890/json?finance_charts_json_callback=finance_charts_json_callback

它的响应标题:

HTTP/1.1 200 OK
Date: Wed, 30 Apr 2014 12:01:08 GMT
P3P: policyref="http://info.yahoo.com/w3c/p3p.xml", CP="CAO ... GOV"

一切正常.

当我尝试从另一台服务器获取文件时,它的响应标头:

Cache-Control: no-cache

Pragma: no-cache

编辑、更新

尝试

$(function() {
    $.getJSON("https://query.yahooapis.com/v1/public/yql?q=select"
              +"* from csv where url='http://finviz.com/export.ashx?'"        
              +"&format=json&diagnostics=true&callback=?"
      , function (data, textStatus, jqxhr) {
        $.each(data.query.results.row, function (index, value) {
            jqxhr.promise()
            .done(function () {
                    $("<li>", {
                      "text": value.col2 + " " + value.col8
                    })
                    .css("padding", "8px")
                    .appendTo("ol");
            })
            .always(function () {
                if (index === 4999) {
                  console.log(data.query
                            , data.query.diagnostics.warning
                            , data.query.results.row.length
                            , index
                            , $("li").length);
                };
            });
        });
    });
});
