使用javascript将JQGrid数据导出到Excel

问题描述：

我想以csv格式下载网格数据，方法是查看链接 http://jsfiddle.net / hybrid13i / JXrwM / 并使用 JSONToCSVConvertor（$（＃reportGrid）。jqGrid（getGridParam，data），Report，true）;

I want to download the grid data in csv format , by looking at the link http://jsfiddle.net/hybrid13i/JXrwM/ and using JSONToCSVConvertor($("#reportGrid").jqGrid("getGridParam", "data"),"Report",true);

你可以下载一个csv文件，但它的列名是变量名，不标记任何想法如何解决这个问题，或者还有另一个解决方案

you can download a csv file but its column name are variable names not label any idea how can i fix this , or there is another solution

感谢Oleg和发布 http://jsfiddle.net/hybrid13i/JXrwM/ 几乎没有增强，这是我的最终解决方案

Thanks to Oleg and the man who posted http://jsfiddle.net/hybrid13i/JXrwM/ with little enhancement in it this is my final solution

function JSONToCSVConvertor(JSONData, ReportTitle, ShowLabel,headers,excludeColumns,
    fileName) {
//If JSONData is not an object then JSON.parse will parse the JSON string in an Object
var arrData = typeof JSONData != 'object' ? JSON.parse(JSONData) : JSONData;

var CSV = '';    
//Set Report title in first row or line

CSV += ReportTitle + '\r\n\n';

//This condition will generate the Label/Header
if (ShowLabel) {
    var row = "";

    if(headers)
    {
        row = headers.join(',');
    }
    else
    {
        //This loop will extract the label from 1st index of on array
        for (var index in arrData[0]) {         
            //Now convert each value to string and comma-seprated
            row += index + ',';
        }
    }
    row = row.slice(0, -1);     

    //append Label row with line break
    CSV += row + '\r\n';
}

//1st loop is to extract each row
for (var i = 0; i < arrData.length; i++) {
    var row = "";

    //2nd loop will extract each column and convert it in string comma-seprated
    for (var colName in arrData[i]) {
        if(excludeColumns && excludeColumns.indexOf(colName))
            continue;
        row += '"' + arrData[i][colName] + '",';
    }

    row.slice(0, row.length - 1);

    //add a line break after each row
    CSV += row + '\r\n';
}

if (CSV == '') {        
    alert("Invalid data");
    return;
}   

if(!fileName)
{
    //Generate a file name
     fileName = "MyReport_";
    //this will remove the blank-spaces from the title and replace it with an underscore
    fileName += ReportTitle.replace(/ /g,"_");   
}

if (navigator.appName == "Microsoft Internet Explorer") {    
    var oWin = window.open();
    oWin.document.write('sep=,\r\n' + CSV);
    oWin.document.close();
    oWin.document.execCommand('SaveAs', true, fileName + ".csv");
    oWin.close();
  }  
else
{

    //Initialize file format you want csv or xls
    var uri = 'data:text/csv;charset=utf-8,' + escape(CSV);

    // Now the little tricky part.
    // you can use either>> window.open(uri);
    // but this will not work in some browsers
    // or you will not get the correct file extension    

    //this trick will generate a temp <a /> tag
    var link = document.createElement("a");    
    link.href = uri;

    //set the visibility hidden so it will not effect on your web-layout
    link.style = "visibility:hidden";
    link.download = fileName + ".csv";

    //this part will append the anchor tag and remove it after automatic click
    document.body.appendChild(link);
    link.click();
    document.body.removeChild(link);
 }
   }

用法：

    JSONToCSVConvertor($(grid).jqGrid("getGridParam", "data"), $("#reportHeader").text().trim(),true,$(grid).jqGrid("getGridParam", "colNames"),["_id_"],"Report");

注意请注意此解决方案在IE中不起作用

NOTE Please note that this solution will not work in IE
