js把頁面的table標簽導出為csv

// 使用該保存方法,table必須外嵌一個div且不能有任何其他元素 否則ie下載會出現其他數據

　//tableid , title 為文件保存的文件名

function saveCode(tableid, title) {
    var winname;
    try {
        if (navigator.userAgent.indexOf("MSIE") > 0)         //IE瀏覽器 
        {
            var strHTML = $("#" + tableid).parent().html();
            //alert("IE瀏覽器");
            winname = window.open("ToExcel", "_blank", 'top=10000'); 

            winname.document.open('text/html', 'replace');
            winname.document.write("<style>");
            winname.document.write("table{border:solid 1px #000;text-align:center;border-collapse:collapse; border-spacing:0;}");
            winname.document.write("table td{border:solid 1px #000;text-align:center;}");
            winname.document.write("table th{border:solid 1px #000;text-align:center;}");
            winname.document.write("</style>");
            winname.document.write(strHTML);
            winname.document.execCommand('SaveAs', '', title + '.xls');
            document.execCommand("ClearAuthenticationCache");
            winname.close();

　　開發中遇到一些需要導出數據之類的可以試試該方式 (ps:阿拉伯語言有bug不建議使用)
