javascript 导出 有点遗憾是因为 这个导出会带出一个网页框 ， 可以用

function getXlsFromTbl(obj, title) {
    //var openPara = "left=" + (window.screen.width / 2 - width / 2) + ",top=" + (window.screen.height / 2 - height / 2) + ",scrollbars=no,width=" + width + ",height=" + height;
    var winname = window.open('', '_blank', 'height=100px,width=100px');
    var strHTML = document.getElementById(obj).innerHTML;
    winname.document.open('text/html', 'replace');
    winname.document.writeln(strHTML);
    var d = new Date();
    var curYear = d.getYear();
    var curMonth = "" + (d.getMonth() + 1);
    var curDate = "" + d.getDate();
    var curHour = "" + d.getHours();
    var curMinute = "" + d.getMinutes();
    var curSecond = "" + d.getSeconds();
    if (curMonth.length == 1) {
        curMonth = "0" + curMonth;
    }
    if (curDate.length == 1) {
        curDate = "0" + curDate;
    }
    if (curHour.length == 1) {
        curHour = "0" + curHour;
    }
    if (curMinute.length == 1) {
        curMinute = "0" + curMinute;
    }
    if (curSecond.length == 1) {
        curSecond = "0" + curSecond;
    }
    var fileName = title  + "_" + curYear + curMonth + curDate + curHour + curMinute + curSecond + ".xls";

    winname.document.execCommand('saveas', '', fileName);
    winname.close();
}
</script>

onclick 调用;      //getXlsFromTbl('tableToEXC',$("#my_title_name").text());

方法二  其实是同一个方法
