javascript实现客户端兼容各浏览器创建csv并下载的方法

$("#radarDLBut").click(function(){var data = [displayData["radar_chart"]["r_label"],displayData["radar_chart"]["r_default"]]; var csvContent = "data:text/csv;charset=utf-8,/ufeff";if (window.navigator.msSaveOrOpenBlob) {  csvContent = "/ufeff";}data.forEach(function(infoArray, index){  dataString = infoArray.join(",");  csvContent += index < data.length ? dataString+ "/n" : dataString;});if (window.navigator.msSaveOrOpenBlob) {  // if browser is IE  var blob = new Blob([decodeURIComponent(encodeURI(csvContent))],{ type: "text/csv;charset=utf-8;"  });  navigator.msSaveBlob(blob, 'subject.csv');}else{  var encodedUri = encodeURI(csvContent);  var link = document.createElement("a");  link.setAttribute("href", encodedUri);  link.setAttribute("download", "subject.csv");  document.body.appendChild(link);  link.click();}});
