在jquery或jqGrid中导出到excel

Question

我有一个jqGrid,我从JSON格式的服务器(java)一次获取数据.我希望将jqGrid中的数据导出为Excel格式.

直到现在我看到这个页面在IE中给我一个错误'o.url is null or not an object' grid.import.js

另外我看到这个演示在导出按钮的工具提示上,Export To Excel但是保存的文件是xml格式.

所以我想任何可以使用javascript或jquery插件或使用jqgrid的内置功能将我的JSON字符串转换为excel的建议.

我的jqGrid

我的jqGrid代码

grid = jQuery("#list2");
                grid.jqGrid({

您不必使用Excel格式导出文件,以便将数据导入Excel.出口通常要容易得多CSV.CSV默认情况下,文件应与Excel关联,因此它应该包含Excel图标和所有内容.XML我认为会以同样的方式工作,但CSV格式要轻得多,在这种情况下做同样的工作.转换JSON到CSV很简单:

var response = JSON.parse(responseJSON).response;
var csv = arrayToCSV(response);

function arrayToCSV(arr) {
    var columnNames = [];
    var rows = [];
    for (var i=0, len=arr.length; i<len; i++) {
        // Each obj represents a row in the table
        var obj = arr[i];
        // row will collect data from obj
        var row = [];
        for (var key in obj) {
            // Don't iterate through prototype stuff
            if (!obj.hasOwnProperty(key)) continue;
            // Collect the column names only once
            if (i === 0) columnNames.push(prepareValueForCSV(key));
            // Collect the data
            row.push(prepareValueForCSV(obj[key]));
        }
        // Push each row to the main collection as csv string
        rows.push(row.join(','));
    }
    // Put the columnNames at the beginning of all the rows
    rows.unshift(columnNames.join(','));
    // Return the csv string
    return rows.join('\n');
}

// This function allows us to have commas, line breaks, and double 
// quotes in our value without breaking CSV format.
function prepareValueForCSV(val) {
    val = '' + val;
    // Escape quotes to avoid ending the value prematurely.
    val = val.replace(/"/g, '""');
    return '"' + val + '"';
}
