静态表格table

<table class="table tableStyles" id="tables">
        <caption>不正经的统计表</caption><!--可以生成表格的标题-->
        <thead>
            <tr>
                <th>品牌</th>
                <th>门店</th>

2.Js代码

①利用html5的download属性，点击下载该文件

<a id="dlink"  style="display:none;"></a>
<input type="button" onclick="tableToExcel(‘tables‘, ‘name‘, ‘myfile.xls‘)" value="Export to Excel">

<script type="text/javascript">
        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();
            }
        })()
    </script>

②创建ActiveXObject对象复制到表格中

1 <input id="Button1" type="button" value="导出EXCEL" onclick="javascript:excels(‘tables‘)" />

<script type="text/javascript">
        var timer;
        function getExplorer(){//获取浏览器
            var explorer=window.navigator.userAgent;
            if(explorer.indexOf("MSIE") >= 0|| (explorer.indexOf("Windows NT 6.1;") >= 0 && explorer.indexOf("Trident/7.0;") >= 0)){
                return ‘ie‘;
            }else if (explorer.indexOf("Firefox") >= 0) {
                return ‘Firefox‘;
            }else if(explorer.indexOf("Chrome") >= 0){
                return ‘Chrome‘;
            }else if(explorer.indexOf("Opera") >= 0){
                return ‘Opera‘;
            }else if(explorer.indexOf("Safari") >= 0){
                return ‘Safari‘;
            }
        }
        function excels(table){
            if(getExplorer()==‘ie‘){
                var curTbl = document.getElementById(table);
                var oXl=new ActiveXObject("Excel.Application");//创建AX对象excel 
                var oWB = oXL.Workbooks.Add();//获取workbook对象
                var xlsheet = oWB.Worksheets(1);//激活当前sheet
                var sel = document.body.createTextRange();
                sel.moveToElementText(curTbl);//把表格中的内容移到TextRange中 
                sel.select;//全选TextRange中内容
                sel.execCommand("Copy");//复制TextRange中内容
                xlsheet.Paste();//粘贴到活动的EXCEL中
                oXL.Visible = true;//设置excel可见属性
                try{
                    var filename = oXL.Application.GetSaveAsFilename("Excel.xls", "Excel Spreadsheets (*.xls), *.xls");
                }catch(e){
                    window.print("Nested catch caught " + e);
                }finally{
                    oWB.SaveAs(filename);
                    oWB.Close(savechanges = false);
                    oXL.Quit();
                    oXL = null;//结束excel进程，退出完成
                    timer = window.setInterval("Cleanup();", 1);
                }
            }else{
                tableToExcel("tables");
            }
        }
        function Cleanup(){
            window.clearInterval(timer);
            CollectGarbage();//CollectGarbage,是IE的一个特有属性,用于释放内存的
        }
        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};

        })();
