问题描述

我需要什么样的:
我们在这是以逗号deliminated值response.d值。现在我想response.d的数据导出到.csv文件。

我写了这个函数来执行此。我已收到response.d的数据,但不能导出到.csv文件,所以给这个问题以.csv文件导出数据的解决方案。

 函数BindSubDivCSV(){
  $阿贾克斯({
      键入:POST,
      网址:../../Web$c$cService.asmx / ShowTrackSectorDepartureList
      数据:{},
      的contentType:应用/ JSON的;字符集= UTF-8,
      数据类型:JSON
      成功:函数(响应){
        警报(response.d); //导出为CSV格式的功能,这里需要
      },
      错误:功能(数据){}
  });
  返回false;
}


解决方案

在情况下,您对如何在服务器端的作品无法控制,这里是我在另一个SO问题都提供了一个客户端解决方案,为待定OP接受:导出为CSV使用jQuery和HTML

有一定的要求和限制,你将不得不考虑,正如我在我的答案在那里,它有更多的细节提及。


这是相同的演示我已提出:
http://jsfiddle.net/terryyounghk/KPEGU/

和给你什么样的剧本看起来像一个粗略的想法。

你需要改变的是你如何遍历你的数据(在其他问题的情况下,它是表格单元格)来构造一个有效的CSV字符串。这应该是微不足道的。

$(文件)。就绪(函数(){

 函数exportTableToCSV($表,文件名){        变量$行= $ table.find('TR:有(TD))            //临时分隔符不可能通过键盘键入
            //这是为了避免意外分裂的实际内容
            tmpColDelim = String.fromChar code(11),//垂直制表符
            tmpRowDelim = String.fromChar code(0),//空字符            //为CSV格式的实际分隔符
            colDelim =',',
            rowDelim =\\ r \\ n',            //抓斗从文本到表CSV格式的字符串
            CSV ='+ $ rows.map(功能(我行){
                VAR $行= $(行)
                    $ COLS = $ row.find('TD');                返回$ cols.map(函数(J,COL){
                    变量$ COL = $(COL)
                        文字= $ col.text();                    返回text.replace('',,); //逃脱双引号                })获得()连接(tmpColDelim)。            })。获得()。加入(tmpRowDelim)
                .split(tmpRowDelim)。加入(rowDelim)
                .split(tmpColDelim)。加入(colDelim)+'',            //数据URI
            csvData ='数据:应用程序/ CSV;字符集= UTF-8,'+ EN codeURIComponent(CSV);        $(本)
            .attr({
            下载:文件名,
                HREF:csvData,
                目标:_blank
        });
    }    //这必须是一个超级链接
    $(出口)。在('点击',功能(事件){
        // CSV
        exportTableToCSV.apply(这一点,[$('#dvData>表),export.csv']);        //如果CSV,不做大事。preventDefault()或返回false
        //实际上,我们需要这是一个典型的超级链接
    });
});

What I needed: We have value in the response.d that is comma deliminated value. Now I want to export the data of response.d to .csv file.

I have written this function to perform this. I have received the data in response.d but not exporting to the .csv file, so give the solution for this problem to export data in .csv file.

function BindSubDivCSV(){ 
  $.ajax({
      type: "POST", 
      url: "../../WebCodeService.asmx / ShowTrackSectorDepartureList", 
      data: "{}", 
      contentType: "application/json; charset=utf-8", 
      dataType: "json",
      success: function (response) {  
        alert(response.d);//export to csv function needed here
      },
      error: function (data) {}
  });
  return false;
}

解决方案

In case you have no control over how the server-side works, here is a client-side solution that I have offered in another SO question, pending for that OP's acceptance: Export to CSV using jQuery and html

There are certain restrictions or limitations you will have to consider, as I have mentioned in my answer over there, which has more details.


This is the same demo I have offered: http://jsfiddle.net/terryyounghk/KPEGU/

And to give you a rough idea of what the script looks like.

What you need to change is how you iterate your data (in the other question's case it was table cells) to construct a valid CSV string. This should be trivial.

$(document).ready(function () {

    function exportTableToCSV($table, filename) {

        var $rows = $table.find('tr:has(td)'),

            // Temporary delimiter characters unlikely to be typed by keyboard
            // This is to avoid accidentally splitting the actual contents
            tmpColDelim = String.fromCharCode(11), // vertical tab character
            tmpRowDelim = String.fromCharCode(0), // null character

            // actual delimiter characters for CSV format
            colDelim = '","',
            rowDelim = '"\r\n"',

            // Grab text from table into CSV formatted string
            csv = '"' + $rows.map(function (i, row) {
                var $row = $(row),
                    $cols = $row.find('td');

                return $cols.map(function (j, col) {
                    var $col = $(col),
                        text = $col.text();

                    return text.replace('"', '""'); // escape double quotes

                }).get().join(tmpColDelim);

            }).get().join(tmpRowDelim)
                .split(tmpRowDelim).join(rowDelim)
                .split(tmpColDelim).join(colDelim) + '"',

            // Data URI
            csvData = 'data:application/csv;charset=utf-8,' + encodeURIComponent(csv);

        $(this)
            .attr({
            'download': filename,
                'href': csvData,
                'target': '_blank'
        });
    }

    // This must be a hyperlink
    $(".export").on('click', function (event) {
        // CSV
        exportTableToCSV.apply(this, [$('#dvData>table'), 'export.csv']);

        // IF CSV, don't do event.preventDefault() or return false
        // We actually need this to be a typical hyperlink
    });
});
