必须使用datagrid-export.js，复制，粘贴
(function($){ function getRows(target){ var state = $(target).data('datagrid'); if (state.filterSource){ return state.filterSource.rows; } else { return state.data.rows; } } function toHtml(target, rows){ rows = rows || getRows(target); var dg = $(target); var data = ['<table border="1" rull="all" style="border-collapse:collapse">']; var fields = dg.datagrid('getColumnFields',true).concat(dg.datagrid('getColumnFields',false)); var trStyle = 'height:32px'; var tdStyle0 = 'vertical-align:middle;padding:0 4px'; data.push('<tr style="'+trStyle+'">'); for(var i=0; i<fields.length; i++){ var col = dg.datagrid('getColumnOption', fields[i]); var tdStyle = tdStyle0 + ';'+col.boxWidth+'px;'; data.push('<th style="'+tdStyle+'">'+col.title+'</th>'); } data.push('</tr>'); $.map(rows, function(row){ data.push('<tr style="'+trStyle+'">'); for(var i=0; i<fields.length; i++){ var field = fields[i]; data.push( '<td style="'+tdStyle0+'">'+row[field]+'</td>' ); } data.push('</tr>'); }); data.push('</table>'); return data.join(''); } function toArray(target, rows){ rows = rows || getRows(target); var dg = $(target); var fields = dg.datagrid('getColumnFields',true).concat(dg.datagrid('getColumnFields',false)); var data = []; var r = []; for(var i=0; i<fields.length; i++){ var col = dg.datagrid('getColumnOption', fields[i]); r.push(col.title); } data.push(r); $.map(rows, function(row){ var r = []; for(var i=0; i<fields.length; i++){ r.push(row[fields[i]]); } data.push(r); }); return data; } function print(target, param){ var title = null; var rows = null; if (typeof param == 'string'){ title = param; } else { title = param['title']; rows = param['rows']; } var newWindow = window.open('', '', 'width=800, height=500'); var document = newWindow.document.open(); var content = '<!doctype html>' + '<html>' + '<head>' + '<meta charset="utf-8">' + '<title>'+title+'</title>' + '</head>' + '<body>' + toHtml(target, rows) + '</body>' + '</html>'; document.write(content); document.close(); newWindow.print(); } function b64toBlob(data){ var sliceSize = 512; var chars = atob(data); var byteArrays = []; for(var offset=0; offset<chars.length; offset+=sliceSize){ var slice = chars.slice(offset, offset+sliceSize); var byteNumbers = new Array(slice.length); for(var i=0; i<slice.length; i++){ byteNumbers[i] = slice.charCodeAt(i); } var byteArray = new Uint8Array(byteNumbers); byteArrays.push(byteArray); } return new Blob(byteArrays, { type: '' }); } function toExcel(target, param){ var filename = null; var rows = null; var worksheet = 'Worksheet'; if (typeof param == 'string'){ filename = param; } else { filename = param['filename']; rows = param['rows']; worksheet = param['worksheet'] || 'Worksheet'; } var dg = $(target); var uri = 'data:application/vnd.ms-excel;base64,' , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><meta http-equiv="content-type" content="application/vnd.ms-excel; charset=UTF-8"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body>{table}</body></html>' , base64 = function (s) { return window.btoa(unescape(encodeURIComponent(s))) } , format = function (s, c) { return s.replace(/{(w+)}/g, function (m, p) { return c[p]; }) } var table = toHtml(target, rows); var ctx = { worksheet: worksheet, table: table }; var data = base64(format(template, ctx)); if (window.navigator.msSaveBlob){ var blob = b64toBlob(data); window.navigator.msSaveBlob(blob, filename); } else { var alink = $('<a style="display:none"></a>').appendTo('body'); alink[0].href = uri + data; alink[0].download = filename; alink[0].click(); alink.remove(); } } $.extend($.fn.datagrid.methods, { toHtml: function(jq, rows){ return toHtml(jq[0], rows); }, toArray: function(jq, rows){ return toArray(jq[0], rows); }, toExcel: function(jq, param){ return jq.each(function(){ toExcel(this, param); }); }, print: function(jq, param){ return jq.each(function(){ print(this, param); }); } }); })(jQuery);
然后，就可以调用语法了
$("#offlineTable").datagrid('toExcel', 'myExcel.xls');
toExcel()是方法，后面的是自定义名字
但是这样只能导出当前的分页数据，那么需要导出前，使用ajax将所有rows数据传递到前台，然后使用
$("#offlineTable").datagrid('toExcel', {
filename: '还阔以.xls',
rows: data.rows,
worksheet: 'Worksheet'
});
将获取数据的rows覆盖导出的rows,然后就搞定了
