方式一

var jsonData = [

{

name:'路人甲',

phone:'123456',

email:'123@123456.com'

},

{

name:'炮灰乙',

phone:'123456',

email:'123@123456.com'

},

{

name:'土匪丙',

phone:'123456',

email:'123@123456.com'

},

{

name:'流氓丁',

phone:'123456',

email:'123@123456.com'

},

]

function JSONToCSVConvertor(JSONData, ReportTitle, ShowLabel) {

//If JSONData is not an object then JSON.parse will parse the JSON string in an Object

var arrData = typeof JSONData != 'object' ? JSON.parse(JSONData) : JSONData;

var CSV = '';

//Set Report title in first row or line

CSV += '姓名,电话,邮箱\n';

//This condition will generate the Label/Header

// if (ShowLabel) {

// var row = "";

//

// //This loop will extract the label from 1st index of on array

// for (var index in arrData[0]) {

//

// //Now convert each value to string and comma-seprated

// row += index + ',';

// }

//

// row = row.slice(0, -1);

//

// //append Label row with line break

// CSV += row + '\r\n';

// }

//1st loop is to extract each row

for (var i = 0; i < arrData.length; i++) {

var row = "";

//2nd loop will extract each column and convert it in string comma-seprated

for (var index in arrData[i]) {

row += '"' + arrData[i][index] + '",';

}

row.slice(0, row.length - 1);

//add a line break after each row

CSV += row + '\r\n';

}

if (CSV == '') {

alert("Invalid data");

return;

}

//Generate a file name

var fileName = "MyReport_";

//this will remove the blank-spaces from the title and replace it with an underscore

fileName += ReportTitle.replace(/ /g,"_");

//Initialize file format you want csv or xls

CSV = encodeURIComponent(CSV);

var uri = 'data:text/csv;charset=utf-8,\ufeff' + CSV;

// Now the little tricky part.

// you can use either>> window.open(uri);

// but this will not work in some browsers

// or you will not get the correct file extension

//this trick will generate a temp tag

var link = document.createElement("a");

link.href = uri;

//set the visibility hidden so it will not effect on your web-layout

link.style = "visibility:hidden";

link.download = fileName + ".csv";

//this part will append the anchor tag and remove it after automatic click

document.body.appendChild(link);

link.click();

document.body.removeChild(link);

方式二：

function TableToExcel(){

//要导出的json数据

var jsonData = [

{

name:'001',

id:'621699190001011231'

},

{

name:'002',

id:'52069919000101547X'

},

{

name:'003',

id:'423699190103015469'

},

{

name:'004',

id:'341655190105011749'

}

]

//导出前要将json转成table格式

//列标题

var str = '

nameid';

//具体数值 遍历

for(let i = 0;i < jsonData.length;i++){

str += '

';

for(let item in jsonData[i]){

var cellvalue = jsonData[i][item];

//不让表格显示科学计数法或者其他格式

//方法1 tr里面加 style="mso-number-format:'\@';" 方法2 是改为 = 'XXXX'格式

//如果纯数字且超过15位

/*var reg = /^[0-9]+.?[0-9]*$/;

if ((cellvalue.length>15) && (reg.test(cellvalue))){

//cellvalue = '="' + cellvalue + '"';

}*/

//此处用`取代'，具体用法搜索模板字符串 ES6特性

str+=`

${cellvalue}`;

// str+=`

${cellvalue}`;

}

str+='

';

}

var worksheet = '导出结果'

var uri = 'data:application/vnd.ms-excel;base64,';

//下载的表格模板数据

var template = `

xmlns:x="urn:schemas-microsoft-com:office:excel"

xmlns="http://www.w3.org/TR/REC-html40">

`;

//下载模板

function base64 (s) { return window.btoa(unescape(encodeURIComponent(s)))}

window.location.href = uri + base64(template);

}
