JQuery EasyUI DataGrid列表所见所得随意导出excel

1.抽取DataGrid列表数据

function ExportNormal(strXlsName, exportGrid, postUrl, hiddenColumns) {
    /// <summary>
    /// 提交DataGrid数据
    /// </summary>
    var f = $('<form action="' + postUrl + '?ac=normal" method="post" id="fmExport1"></form>');
    var i = $('<input type="hidden" id="Content" name="Content" />');
    var l = $('<input type="hidden" id="Name" name="Name" />');
    i.val(ChangeToTableNormal(exportGrid, hiddenColumns));
    i.appendTo(f);
    l.val(strXlsName);
    l.appendTo(f);
    f.appendTo(document.body).submit();
    $("#fmExport1").remove();
}
function ChangeToTableNormal(printDatagrid, hiddenColumns) {
    /// <summary>
    /// 提交DataGrid数据
    /// </summary>
    var frozenColumns = printDatagrid.datagrid("options").frozenColumns;  // 得到frozenColumns对象 
    var columns = printDatagrid.datagrid("options").columns;  // 得到frozenColumns对象 
    columns = (frozenColumns[0] || []).concat(columns[0] || []).concat(columns[1] || []);
    var rows = printDatagrid.datagrid("getRows");
    var data = new Array();
    var tmp = new Array();
    //列名
    $.map(columns, function (a) {
        if (!a.hidden && a.field) {
            tmp.push(a.title);
        }
    });
    data.push(tmp);
    $.map(rows, function (r) {
        tmp = new Array();
        $.map(columns, function (c) {
            if (!c.hidden && c.field) {
                if (c.formatter) {
                    var v = c.formatter.call(this, r[c.field], r) || "";
                    v = $(v).text()
                    if (v.toString().indexOf("<a") >= 0)
                        tmp.push(fixGetValue(r[c.field]));
                    else
                        tmp.push(v);
                } else {
                    tmp.push(fixGetValue(r[c.field]));
                }
            }
        });
        data.push(tmp);
    });
    return JSON.stringify(data);
}
function fixGetValue(obj) {
    return obj ? obj : "";
}

2.把抽取的数据提交到后台，生成excel

 ExportNormal("人员名单导出", $('#flexigridData'),"/CreateExcel.aspx");
 //提交的数据格式 Content:[["姓名","性别","证件号","手机号","证件类型"],["小强","男","333333333333333","1800000000","身份证"]]
