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>
