推荐答案
我使用 jspdf 得到了想要的结果.我实现了以下几点:-
I used jspdf to get the desired results.Following points i achieved:-
1) This works in all versions of IE.
2) You can give the freeze column and freeze row options also in Excel
.
我使用的库
1)downloadify.js
2)swfobject.js
3)downloadify.swf
我使用过的函数
1)getHtmlForExport(); // gives the html of the table to be exported.
2)tableToExcel();// converts html code to Microsoft Excel specific XML code
3)handleExcelExport();// downloads excel specific XML to excel file.
var tableToExcel = function (table, horizontalFreezeRowNo, VerticalFreezeRowNo) {
var worksheetString = '';
//worksheet freeze pane options
worksheetString += '<x:WorksheetOptions xmlns="urn:schemas-microsoft-com:office:excel"><x:Selected/><x:FreezePanes/><x:FrozenNoSplit/><x:ActivePane>2</x:ActivePane>';
if (horizontalFreezeRowNo !== undefined)
worksheetString += '<x:SplitHorizontal>' + horizontalFreezeRowNo + '</x:SplitHorizontal><x:TopRowBottomPane>' + horizontalFreezeRowNo + '</x:TopRowBottomPane>';
if (VerticalFreezeRowNo !== undefined)
worksheetString += '<x:SplitVertical>' + VerticalFreezeRowNo + '</x:SplitVertical><x:LeftColumnRightPane>' + VerticalFreezeRowNo + '</x:LeftColumnRightPane>';
worksheetString += '</x:WorksheetOptions>';
var 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"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions>' + worksheetString + '</x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--><meta http-equiv="content-type" content="text/plain; charset=UTF-8"/></head><body><table>{table}</table></body></html>'
, format = function (s, c) {
return s.replace(/{(w+)}/g, function (m, p) {
return c[p];
})
};
if (!table.nodeType)
table = document.getElementById(table)
var ctx = {
table: table.innerHTML
}
$("#exportTable").remove();
return format(template, ctx)
}
function handleExcelExport(gridConfig) {
$("." + gridConfig.objectID + "Export").downloadify({
filename: function () {
var elementClicked = this.el;
var headerText = $(elementClicked).parents('.portlet').find('.portlet-title h8').text();
var fileName;
if (elementClicked == undefined || headerText == undefined) {
fileName = "excel"
} else {
fileName = headerText.toString().trim()
}
return fileName + ".xls";
},
data: function () {
var elementClicked = this.el;
getHtmlForExport(elementClicked, gridConfig);
return (tableToExcel('exportTable', 1, 1));// table id, horizontal freeze,vertical freeze
},
onComplete: function () {
},
onCancel: function () {
},
onError: function () {
},
swf: 'resources/js/downloadify/downloadify.swf',
downloadImage: 'resources/css/images/excelDownload.png',
width: 65,
height: 20,
transparent: true,
append: false
});
}
对于 getHtmlForExport，您必须编写逻辑以获取要导出的表的 html.
and for getHtmlForExport you have to write the logic to get the html of table you want to export .
