<button id="down" onclick="download()">下载</button>
<script>
function download() {
$(document).on("click", "#down", function () {//按钮点击事件
var $trs = $("#example").find("tr");//表格id元素
var str = "";
for (var i = 0; i < $trs.length; i++) {
var $tds = $trs.eq(i).find("td,th");
for (var j = 0; j < $tds.length; j++) {
str += $tds.eq(j).text() + ",";
}
str += "\n";
}
var aaaa = "data:text/csv;charset=utf-8,\ufeff" + str;
var link = document.createElement("a");
link.setAttribute("href", aaaa);
