简介： 前端js实现打印（导出）excel表格

产品原型：

功能需求：点击导出考勤表格按钮，会自动下载成Excel格式

jsp页面代码：

<div class="tools">
<button type="button" class="btn green" id="excell"  onclick="method5('dataTable')">导出考勤表</button>
</div>

js代码

//打印表格
var idTmr;  
function  getExplorer() {  
    var explorer = window.navigator.userAgent ;  
    //ie  
    if (explorer.indexOf("MSIE") >= 0) {
            return 'ie';
        }
        //firefox  
        else if (explorer.indexOf("Firefox") >= 0) {
            return 'Firefox';
        }
        //Chrome  
        else if (explorer.indexOf("Chrome") >= 0) {
            return 'Chrome';
        }
        //Opera  
        else if (explorer.indexOf("Opera") >= 0) {
            return 'Opera';
        }
        //Safari  
        else if (explorer.indexOf("Safari") >= 0) {
            return 'Safari';
        }
    }
    function method5(tableid) {
        if (getExplorer() == 'ie') {

            sel.select();
            sel.execCommand("Copy");
            xlsheet.Paste();
            oXL.Visible = true;
            try {

                        "Excel Spreadsheets (*.xls), *.xls");
            } catch (e) {

                oXL = null;
                idTmr = window.setInterval("Cleanup();", 1);
            }
        } else {
            tableToExcel(tableid)
        }
    }
    function Cleanup() {
        window.clearInterval(idTmr);
        CollectGarbage();
    }
    var tableToExcel = (function() {
        var uri = 'data:application/vnd.ms-excel;base64,', template = '<html><head><meta charset="UTF-8"></head><body><table  border="1">{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))
