在我的MVC 4应用程序中，我使用jquery.table2excel.js插件将表格内容下载到Excel：
;(function ( $, window, document, undefined ) {
var pluginName = "table2excel",
defaults = {
exclude: ".noExl",
name: "Table2Excel"
};
// The actual plugin constructor
function Plugin ( element, options ) {
this.element = element;
// jQuery has an extend method which merges the contents of two or
// more objects, storing the result in the first object. The first object
// is generally empty as we don't want to alter the default options for
// future instances of the plugin
//
this.settings = $.extend( {}, defaults, options );
this._defaults = defaults;
this._name = pluginName;
this.init();
}
Plugin.prototype = {
init: function () {
var e = this;
e.template = {
head: "<html xmlns:o=\"urn:schemas-microsoft-com:office:office\" xmlns:x=\"urn:schemas-microsoft-com:office:excel\" xmlns=\"http://www.w3.org/TR/REC-html40\"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets>",
sheet: {
head: "<x:ExcelWorksheet><x:Name>",
tail: "</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet>"
},
mid: "</x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body>",
table: {
head: "<table>",
tail: "</table>"
},
foot: "</body></html>"
};
e.tableRows = [];
// get contents of table except for exclude
//$(e.element).each( function(i,o) {
// var tempRows = "";
// $(o).find("tr").not(e.settings.exclude).each(function (i,o) {
// tempRows += "<tr>" + $(o).html() + "</tr>";
// });
// e.tableRows.push(tempRows);
//});
$(e.element).each(function (i, o) {
var tempRows = "";
$(o).find("tr").not(e.settings.exclude).each(function (i, o) {
if (e.settings.columns.length == 0) {
tempRows += "<tr>" + $(o).html() + "</tr>";
} else {
var row = "";
e.settings.columns.forEach(function (colIndex) {
//is it a thead or tbody row?
if ($(o).find('th').length > 0) {
row += $(o).find('th:eq(' + colIndex + ')')[0].outerHTML;
} else {
row += $(o).find('td:eq(' + colIndex + ')')[0].outerHTML;
}
})
tempRows += '<tr>' + row + '</tr>';
}
});
e.tableRows.push(tempRows);
});
e.tableToExcel(e.tableRows, e.settings.name);
},
tableToExcel: function (table, name) {
var e = this, fullTemplate="", i, link, a;
e.uri = "data:application/vnd.ms-excel;base64,";
//e.uri = "data:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;base64,";
e.base64 = function (s) {
return window.btoa(unescape(encodeURIComponent(s)));
};
e.format = function (s, c) {
return s.replace(/{(\w+)}/g, function (m, p) {
return c[p];
});
};
e.ctx = {
worksheet: name || "Worksheet",
table: table
};
fullTemplate= e.template.head;
if ( $.isArray(table) ) {
for (i in table) {
//fullTemplate += e.template.sheet.head + "{worksheet" + i + "}" + e.template.sheet.tail;
//fullTemplate += e.template.sheet.head + name + i + "" + e.template.sheet.tail;
fullTemplate += e.template.sheet.head + name + "" + e.template.sheet.tail;
}
}
fullTemplate += e.template.mid;
if ( $.isArray(table) ) {
for (i in table) {
fullTemplate += e.template.table.head + "{table" + i + "}" + e.template.table.tail;
}
}
fullTemplate += e.template.foot;
for (i in table) {
e.ctx["table" + i] = table[i];
}
delete e.ctx.table;
if (typeof msie !== "undefined" && msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./)) // If Internet Explorer
{
if (typeof Blob !== "undefined") {
//use blobs if we can
fullTemplate = [fullTemplate];
//convert to array
var blob1 = new Blob(fullTemplate, { type: "text/html" });
window.navigator.msSaveBlob(blob1, getFileName(e.settings) );
} else {
//otherwise use the iframe and save
//requires a blank iframe on page called txtArea1
txtArea1.document.open("text/html", "replace");
txtArea1.document.write(e.format(fullTemplate, e.ctx));
txtArea1.document.close();
txtArea1.focus();
sa = txtArea1.document.execCommand("SaveAs", true, getFileName(e.settings) );
}
} else {
link = e.uri + e.base64(e.format(fullTemplate, e.ctx));
a = document.createElement("a");
a.download = getFileName(e.settings);
a.href = link;
document.body.appendChild(a);
a.click();
document.body.removeChild(a);
}
return true;
}
};
function getFileName(settings) {
return ( settings.filename ? settings.filename : "table2excel") + ".xls";
}
$.fn[ pluginName ] = function ( options ) {
var e = this;
e.each(function() {
if ( !$.data( e, "plugin_" + pluginName ) ) {
$.data( e, "plugin_" + pluginName, new Plugin( this, options ) );
}
});
// chain jQuery functions
return e;
};
})( jQuery, window, document );
我的观点脚本：
<script type="text/javascript">
$(function () {
$('#btnExportToExcel').click(function () {
$("#divTableHolder").table2excel({
exclude: ".noExl",
name: "Application Versions",
filename: "Application Versions",
columns: [0, 1, 2, 3]
});
})
})
</script>
功能在Chrome和Firefox中正常运行但是当我尝试在Internet Explorer 11中运行时，我在文件中看到的唯一结果是{table0}。
工作表名称和文件名已正确设置。因此，似乎表的内容未正确加载到文件中。
另一件事是，当我打开文件时，会出现警告：
＆＃34;您尝试打开的文件格式与其他格式不同 由扩展名指定...＆＃34;
我可以通过单击是打开文件。我在脚本或文件名中更改了扩展名为xlsx但在这种情况下我甚至无法打开文件。 此警告出现在Chrome，Firefox和IE中，但我可以忍受。对我来说最重要的是在IE 11中生成报告。

我一直面临同样的问题。它通过在table2excel.js
中添加波纹管代码来解决fullTemplate = e.format(fullTemplate, e.ctx);
var ua = window.navigator.userAgent;
var msie = ua.indexOf("MSIE ");
if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./)) // If Internet Explorer
{
if (typeof Blob !== "undefined") {
//use blobs if we can
fullTemplate = [fullTemplate];
//convert to array
var blob1 = new Blob(fullTemplate, { type: 'text/html' });
window.navigator.msSaveBlob(blob1, 'Download.xls');
return (true);
} else {
//otherwise use the iframe and save
//requires a blank iframe on page called txtArea1
txtArea1.document.open("text/html", "replace");
txtArea1.document.write(fullTemplate);
txtArea1.document.close();
txtArea1.focus();
sa = txtArea1.document.execCommand("SaveAs", true, "Download.xls");
}
} else {
//sa = e.uri + e.base64(fullTemplate);//window.open(e.uri + e.base64(fullTemplate));
link = e.uri + e.base64(e.format(fullTemplate, e.ctx));
a = document.createElement("a");
a.download = getFileName(e.settings);
a.href = link;
document.body.appendChild(a);
a.click();
document.body.removeChild(a);
}
return (sa);

在table2excel.js
fullTemplate = e.format(fullTemplate, e.ctx);
