下面是完整的代码，exportTable是直接调用的方法，tableid是table标签的id，selectField是筛选的数组，只有数组中的列会导出，name是导出的文件名var idTmr;

})()以上是所有代码，因为用的是jqgrid的插件，所以中间有一段代码，使用jqgrid的方法拼接成一个新的表格，这样使用上更加灵活，不仅可以改变样式和结构，还能选择需要导出的列
function gridTable(tableid,selectField){
var columnModel = this.$("#"+tableid).jqGrid('getGridParam', 'colModel');
var dataModel = this.$("#"+tableid).jqGrid("getRowData");
var footerData = this.$("#"+tableid).jqGrid("footerData");
var table = ["<table cellspacing=\"0\" cellpadding=\"5\" rules=\"all\" border=\"1\">"];
//写出列名
table.push("<tr style=\"background-color: #FFE88C;font-weight: bold; white-space: nowrap;\">");
$.each(columnModel,function(i,jqgridcolumn){
if($.inArray(jqgridcolumn.name,selectField)>=0 && !!jqgridcolumn.label && !jqgridcolumn.hidden){
table.push("<td style=\"width:" + jqgridcolumn.width + "px;text-align:" + jqgridcolumn.align + "\">" + jqgridcolumn.label + "</td>");
}
});
table.push("</tr>");
//写数据
$.each(dataModel,function(i,row){
table.push("<tr>");
$.each(columnModel,function(i,jqgridcolumn){
if($.inArray(jqgridcolumn.name,selectField)>=0 && !!jqgridcolumn.label && !jqgridcolumn.hidden){
var text = row[jqgridcolumn.name];
table.push("<td style=\"vnd.ms-excel.numberformat:@;width:" + jqgridcolumn.width + "px;text-align:" + jqgridcolumn.align + "\">"+text+"</td>");
}
});
table.push("</tr>");要设置导出excel的文件名没有直接的方法，只能通过临时创建一个a标签，设置download属性为文件名，然后触发点击事件，“exportExcel”就是我临时创建a标签的id
var tableToExcel = (function() {
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 charset="UTF-8"></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]; }) }
return function(table, selectField, name) {
if (!table.nodeType) table = gridTable(table,selectField);
var ctx = {worksheet: name || 'Worksheet', table: table.outerHTML}
document.getElementById("exportExcel").href = uri
+ base64(format(template, ctx));
document.getElementById("exportExcel").download = name + ".xls";//自定义文件名
document.getElementById("exportExcel").click();
//window.location.href = uri + base64(format(template, ctx))
}
})()
