jqgrid 表格数据导出实例

首先，是一段javascript脚本：
代码如下:
/**
 * 
 * 
 * @param table_id 表格的id
 * @param container_id 容器的id
 * @param form_id 提交表单的id
 * @param title 文件名
 * @param rownumbers
 */ 
function getXlsFromTbl(table_id, container_id ,form_id, title, rownumbers) { 
    try { 
        var content = ""; 

 
        if (table_id != null && table_id != "" && table_id != "null") { 
        <SPAN style="WHITE-SPACE: pre"> </SPAN>content = getTblData($('#' + table_id), $('#' + container_id), rownumbers); 
        } 
        if (content == "") { 
            alert("表格不存在"); 
            return; 
        } 
        var fileName = getExcelFileName(title); 

        doFileExport($('#' + form_id), fileName, content); 
    } 
    catch (e) { 
        alert("导出异常:" + e.name + "->" + e.description + "!"); 
    } 
} 
function getTblData(tableobj, containerobj, rownumbers) { 

 
    var outStr = ""; 
    if (tableobj != null) { 
        var rowdata = tableobj.getRowData(); 
        var Lenr = 1; 

 
        for (i = 0; i < Lenr; i++) { 
            //var Lenc = curTbl.rows(i).cells.length;  
            var th; 
            if (rownumbers == false) { 
                th = containerobj.find('TH:not(:first-child)'); 
            } 
            else { 
                th = containerobj.find('TH'); 
            } 
            th.each(function(index, element) { 
                var j = index + 1;
