方案一：支持IEjavascript

 //導出excel
function exportExcel(DivID,strTitle){
    if(DivID==null)
    {
    return false;
    }
    var jXls, myWorkbook, myWorksheet;    
    try {
        jXls = new ActiveXObject('Excel.Application');
    }
    catch (e) {
        alert("沒法啓動Excel!\n\n若是您確信您的電腦中已經安裝了Excel，"+"那麼請調整IE的安全級別。\n\n具體操做：\n\n"+"工具 → Internet選項 → 安全 → 自定義級別 → 對

沒有標記爲安全的ActiveX進行初始化和腳本運行 → 啓用");
        return false;
    }    
    jXls.DisplayAlerts = false;    
    myWorkbook = jXls.Workbooks.Add();    
    var curTb = document.getElementById(DivID);     
    myWorksheet = myWorkbook.ActiveSheet;    
    myWorksheet.name=strTitle;    
    var sel = document.body.createTextRange(); 
    sel.moveToElementText(curTb);    
    sel.select();    
    window.clipboardData.setData('text','');    
    sel.execCommand("Copy");    
    myWorksheet.Paste();     
    jXls.Visible = true;    
     try{
        var fname = jXls.Application.GetSaveAsFilename("OA數據"+strTitle+".xls", "Excel Spreadsheets (*.xls), *.xls");
        }catch(e){
        print("Nested catch caught " + e);
    }
    finally{
        if(fname!=false)
        {
             myWorkbook .SaveAs(fname);
            alert("數據成功保存在:"+fname);       
        }
     }
     //   myWorkbook .Close(savechanges=false);
     // jXls.Quit();
    window.clipboardData.setData('text','');
    jXls = null;
    myWorkbook = null;
    myWorksheet = null;
}

<table class="oa-el-grid-list" id="tb" style="width:99%" cellspacing="0" cellpadding="0"
            border="0">
            <thead>
                <%=tab_html%>
            </thead>
            <%=TableHtml %>
        </table>


  <input id="btnSavExcel" onclick="exportExcel('tb','……表')" type="button" value="導出"  />

方案2html

<input type="button" onclick="tableToExcel('tablename', 'name')" value="Export to Excel">

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"><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>{table}</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, name) {
if (!table.nodeType) table = document.getElementById(table)
var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}
window.location.href = uri + base64(format(template, ctx))
}
})()

方案3java

<a id="dlink"  style="display:none;"></a>

<input type="button" onclick="tableToExcel('tablename', 'name', 'myfile.xls')" value="Export to Excel">

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"><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>{table}</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, name, filename) {
            if (!table.nodeType) table = document.getElementById(table)
            var ctx = { worksheet: name || 'Worksheet', table: table.innerHTML }

            document.getElementById("dlink").href = uri + base64(format(template, ctx));
            document.getElementById("dlink").download = filename;
            document.getElementById("dlink").click();

        }
    })()

支持：Chrome、Firefox、Opera、Safarinode

根據Json導出Exceljquery
