之前有介绍过如何实现easyui里datagrid内容的打印，今天给大家介绍下如何实现datagrid内容导出为excel文件。以下为代码实现：
export.js
function ChangeToTable(printDatagrid) {
var tableString = '<table cellspacing="0" class="pb">';
var frozenColumns = printDatagrid.datagrid("options").frozenColumns; // 得到frozenColumns对象
var columns = printDatagrid.datagrid("options").columns; // 得到columns对象
var nameList = new Array();
// 载入title
if (typeof columns != 'undefined' && columns != '') {
$(columns).each(function (index) {
tableString += '\n<tr>';
if (typeof frozenColumns != 'undefined' && typeof frozenColumns[index] != 'undefined') {
for (var i = 0; i < frozenColumns[index].length; ++i) {
if (!frozenColumns[index][i].hidden) {
tableString += '\n<th width="' + frozenColumns[index][i].width + '"';
if (typeof frozenColumns[index][i].rowspan != 'undefined' && frozenColumns[index][i].rowspan > 1) {
tableString += ' rowspan="' + frozenColumns[index][i].rowspan + '"';
}
if (typeof frozenColumns[index][i].colspan != 'undefined' && frozenColumns[index][i].colspan > 1) {
tableString += ' colspan="' + frozenColumns[index][i].colspan + '"';
}
if (typeof frozenColumns[index][i].field != 'undefined' && frozenColumns[index][i].field != '') {
nameList.push(frozenColumns[index][i]);
}
tableString += '>' + frozenColumns[0][i].title + '</th>';
}
}
}
for (var i = 0; i < columns[index].length; ++i) {
if (!columns[index][i].hidden) {
tableString += '\n<th width="' + columns[index][i].width + '"';
if (typeof columns[index][i].rowspan != 'undefined' && columns[index][i].rowspan > 1) {
tableString += ' rowspan="' + columns[index][i].rowspan + '"';
}
if (typeof columns[index][i].colspan != 'undefined' && columns[index][i].colspan > 1) {
tableString += ' colspan="' + columns[index][i].colspan + '"';
}
if (typeof columns[index][i].field != 'undefined' && columns[index][i].field != '') {
nameList.push(columns[index][i]);
}
tableString += '>' + columns[index][i].title + '</th>';
}
}
tableString += '\n</tr>';
});
}
// 载入内容
var rows = printDatagrid.datagrid("getRows"); // 这段代码是获取当前页的所有行
for (var i = 0; i < rows.length; ++i) {
tableString += '\n<tr>';
for (var j = 0; j < nameList.length; ++j) {
var e = nameList[j].field.lastIndexOf('_0');
tableString += '\n<td';
if (nameList[j].align != 'undefined' && nameList[j].align != '') {
tableString += ' style="text-align:' + nameList[j].align + ';"';
}
tableString += '>';
if (e + 2 == nameList[j].field.length) {
tableString += rows[i][nameList[j].field.substring(0, e)];
}
else
tableString += rows[i][nameList[j].field];
tableString += '</td>';
}
tableString += '\n</tr>';
}
tableString += '\n</table>';
return tableString;
}
function Export(strXlsName, exportGrid) {
var f = $('<form action="/export.aspx" method="post" id="fm1"></form>');
var i = $('<input type="hidden" id="txtContent" name="txtContent" />');
var l = $('<input type="hidden" id="txtName" name="txtName" />');
i.val(ChangeToTable(exportGrid));
i.appendTo(f);
l.val(strXlsName);
l.appendTo(f);
f.appendTo(document.body).submit();
document.body.removeChild(f);
}
export.aspx
protected void Page_Load(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.Charset = "utf-8";
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.AppendHeader("content-disposition", "attachment;filename=\"" + HttpUtility.HtmlEncode(Request["txtName"]??DateTime.Now.ToString("yyyyMMdd")) + ".xls\"");
Response.ContentType = "Application/ms-excel";
Response.Write("<html>\n<head>\n");
Response.Write("<style type=\"text/css\">\n.pb{font-size:13px;border-collapse:collapse;} "+
"\n.pb th{font-weight:bold;text-align:center;border:0.5pt solid windowtext;padding:2px;} " +
"\n.pb td{border:0.5pt solid windowtext;padding:2px;}\n</style>\n</head>\n");
Response.Write("<body>\n" + Request["txtContent"] + "\n</body>\n</html>");
Response.Flush();
Response.End();
}
其中export.aspx为了防止前台页面内容干扰，前台页面只留：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="export.aspx.cs" Inherits="newland.WebUI.export" ValidateRequest="false" %>
这句话，其他的全部删除。
调用方法：
<a href="javascript:void(0);" onclick="Export('导出excel', $('#grid'));">导出</a>
