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') {
var curTbl = document.getElementById(tableid);
var oXL = new ActiveXObject("Excel.Application");
var oWB = oXL.Workbooks.Add();
var xlsheet = oWB.Worksheets(1);
var sel = document.body.createTextRange();
sel.moveToElementText(curTbl);
sel.select();
sel.execCommand("Copy");
xlsheet.Paste();
oXL.Visible = true;
try {
var fname = oXL.Application.GetSaveAsFilename("Excel.xls",
"Excel Spreadsheets (*.xls), *.xls");
} catch (e) {
print("Nested catch caught " + e);
} finally {
oWB.SaveAs(fname);
oWB.Close(savechanges = false);
oXL.Quit();
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))
}
})()
