需要在不调用后台接口的情况下，将json数据导出到excel表格
最佳解决方案
调用excelExportFn()即可导出excel文件，下面是js代码片段
收藏<script>
const jsonData = [
{
name:'路人甲',
phone:'123456',
email:'123@123456.com',
bool:true
},
{
name:'炮灰乙',
phone:'123456',
email:'123@123456.com',
bool:false
},
{
name:'土匪丙',
phone:'123456',
email:'123@123456.com',
bool:true
},
{
name:'流氓丁',
phone:'123456',
email:'123@123456.com',
bool:false
},
]
excelExportFn();
function excelExportFn(){
let title = ['姓名','电话','邮箱'];
let filter = []; //不导出的字段
exportExcel(jsonData,'测试excel',title,filter);
}
function exportExcel(JSONData, FileName, title, filter) {
if (!JSONData) return;
//转化json为object
var arrData = typeof JSONData != "object" ? JSON.parse(JSONData) : JSONData;
var excel = "<table>";
//设置表头
var row = "<tr>";
if (title) { //使用标题项
for (var i in title) {
row += "<th align='center'>" + title[i] + "</th>";
}
} else {//不使用标题项
for (var i in arrData[0]) {
row += "<th align='center'>" + i + "</th>";
}
}
excel += row + "</tr>";
//设置数据
for (var i = 0; i < arrData.length; i++) {
var row = "<tr>";
for (var index in arrData[i]) {
//判断是否有过滤行
if (filter) {
if (filter.indexOf(index) == -1) {
var value = arrData[i][index] == null ? "" : arrData[i][index];
row += "<td>" + value + "</td>";
}
} else {
var value = arrData[i][index] == null ? "" : arrData[i][index];
row += "<td align='center'>" + value + "</td>";
}
}
excel += row + "</tr>";
}
excel += "</table>";
var excelFile =
"<html xmlns:o='urn:schemas-microsoft-com:office:office' xmlns:x='urn:schemas-microsoft-com:office:excel' xmlns='http://www.w3.org/TR/REC-html40'>";
excelFile +=
'<meta http-equiv="content-type" content="application/vnd.ms-excel; charset=UTF-8">';
excelFile +=
'<meta http-equiv="content-type" content="application/vnd.ms-excel';
excelFile += '; charset=UTF-8">';
excelFile += "<head>";
excelFile += "<!--[if gte mso 9]>";
excelFile += "<xml>";
excelFile += "<x:ExcelWorkbook>";
excelFile += "<x:ExcelWorksheets>";
excelFile += "<x:ExcelWorksheet>";
excelFile += "<x:Name>";
excelFile += "{worksheet}";
excelFile += "</x:Name>";
excelFile += "<x:WorksheetOptions>";
excelFile += "<x:DisplayGridlines/>";
excelFile += "</x:WorksheetOptions>";
excelFile += "</x:ExcelWorksheet>";
excelFile += "</x:ExcelWorksheets>";
excelFile += "</x:ExcelWorkbook>";
excelFile += "</xml>";
excelFile += "<![endif]-->";
excelFile += "</head>";
excelFile += "<body>";
excelFile += excel;
excelFile += "</body>";
excelFile += "</html>";
var uri =
"data:application/vnd.ms-excel;charset=utf-8," +
encodeURIComponent(excelFile);
var link = document.createElement("a");
link.href = uri;
link.style = "visibility:hidden";
link.download = FileName + ".xls";
document.body.appendChild(link);
link.click();
document.body.removeChild(link);
}
