一、js导出Excel
<html>
<head>
</head>
<body>
<scripttype="text/javascript"src="./xlsx.core.min.js"></script>
<scripttype="text/javascript">
/**
*通用的打开下载对话框方法，没有测试过具体兼容性
*@paramurl下载地址，也可以是一个blob对象，必选
[email protected]保存文件名，可选
*/
functionopenDownloadDialog(url,saveName){
if(typeofurl=='object'&&urlinstanceofBlob){
url=URL.createObjectURL(url);//创建blob地址
}
varaLink=document.createElement('a');
aLink.href=url;
aLink.download=saveName||'';//HTML5新增的属性，指定保存文件名，可以不要后缀，注意，file:///模式下不会生效
varevent;
if(window.MouseEvent)event=newMouseEvent('click');
else{
event=document.createEvent('MouseEvents');
event.initMouseEvent('click',true,false,window,0,0,0,0,0,false,false,false,false,0,null);
}
aLink.dispatchEvent(event);
}
//将一个sheet转成最终的excel文件的blob对象，然后利用URL.createObjectURL下载
functionsheet2blob(sheet,sheetName){
sheetName=sheetName||'sheet1';
varworkbook={
SheetNames:[sheetName],
Sheets:{}
};
workbook.Sheets[sheetName]=sheet;
//生成excel的配置项
varwopts={
bookType:'xlsx',//要生成的文件类型
bookSST:false,//是否生成SharedStringTable，官方解释是，如果开启生成速度会下降，但在低版本IOS设备上有更好的兼容性
type:'binary'
};
varwbout=XLSX.write(workbook,wopts);
varblob=newBlob([s2ab(wbout)],{type:"application/octet-stream"});
//字符串转ArrayBuffer
functions2ab(s){
varbuf=newArrayBuffer(s.length);
varview=newUint8Array(buf);
for(vari=0;i!=s.length;++i)view[i]=s.charCodeAt(i)&0xFF;
returnbuf;
}
returnblob;
}
</script>
<scripttype="text/javascript">
varexportDataSource=[{
name:'路人甲',
phone:'123456789',
email:[email protected]'
},{
name:'炮灰乙',
phone:'123456789',
email:[email protected]'
},{
name:'土匪丙',
phone:'123456789',
email:[email protected]'
},{
name:'流氓丁',
phone:'123456789',
email:[email protected]'
},];//导出json数据源
functionexportExcel(){
varexcelItems=[];
for(leti=0;i<exportDataSource.length;i++){
if(exportDataSource[i].name!=""){
excelItems.push({
"姓名":exportDataSource[i].name,
"电话":exportDataSource[i].phone,
"邮箱":exportDataSource[i].email
});//属性
}
}
varsheet=XLSX.utils.json_to_sheet(excelItems);
openDownloadDialog(sheet2blob(sheet),'exportdata.xlsx');
}
</script>
<astyle="float:right;"onclick="exportExcel()">导出下载</a>
</body>
</html>
二、js实现json导出csv
<html>
<head>
<pstyle="font-size:20px;color:red;">使用a标签方式将json导出csv文件</p>
<buttononclick='tableToExcel()'>导出</button>
</head>
<body>
<script>
functiontableToExcel(){
//要导出的json数据
constjsonData=[
{
name:'路人甲',
phone:'123456789',
email:[email protected]'
},
{
name:'炮灰乙',
phone:'123456789',
email:[email protected]'
},
{
name:'土匪丙',
phone:'123456789',
email:[email protected]'
},
{
name:'流氓丁',
phone:'123456789',
email:[email protected]'
},
]
//列标题，逗号隔开，每一个逗号就是隔开一个单元格
letstr=`姓名,电话,邮箱\n`;
//增加\t为了不让表格显示科学计数法或者其他格式
for(leti=0;i<jsonData.length;i++){
for(letiteminjsonData[i]){
str+=`${jsonData[i][item]+'\t'},`;
}
str+='\n';
}
//encodeURIComponent解决中文乱码
leturi='data:text/csv;charset=utf-8,\ufeff'+encodeURIComponent(str);
//通过创建a标签实现
letlink=document.createElement("a");
link.href=uri;
//对下载的文件命名
link.download="json数据表.csv";
document.body.appendChild(link);
link.click();
document.body.removeChild(link);
}
</script>
</body>
</html>
三、js实现json导出csv
<html>
<head>
<pstyle="font-size:20px;color:red;">使用table标签方式将json导出xls文件</p>
<buttononclick='tableToExcel()'>导出</button>
</head>
<body>
<script>
functiontableToExcel(){
//要导出的json数据
constjsonData=[
{
name:'路人甲',
phone:'123456',
email:[email protected]'
},
{
name:'炮灰乙',
phone:'123456',
email:[email protected]'
},
{
name:'土匪丙',
phone:'123456',
email:[email protected]'
},
{
name:'流氓丁',
phone:'123456',
email:[email protected]'
},
]
//列标题
letstr='<tr><td>姓名</td><td>电话</td><td>邮箱</td></tr>';
//循环遍历，每行加入tr标签，每个单元格加td标签
for(leti=0;i<jsonData.length;i++){
str+='<tr>';
for(letiteminjsonData[i]){
//增加\t为了不让表格显示科学计数法或者其他格式
str+=`<td>${jsonData[i][item]+'\t'}</td>`;
}
str+='</tr>';
}
//Worksheet名
letworksheet='Sheet1'
leturi='data:application/vnd.ms-excel;base64,';
//下载的表格模板数据
lettemplate=`<htmlxmlns:o="urn:schemas-microsoft-com:office:office"
xmlns:x="urn:schemas-microsoft-com:office:excel"
xmlns="http://www.w3.org/TR/REC-html40">
<head><!--[ifgtemso9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet>
<x:Name>${worksheet}</x:Name>
<x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet>
</x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]-->
</head><body><table>${str}</table></body></html>`;
//下载模板
window.location.href=uri+base64(template)
}
//输出base64编码
functionbase64(s){returnwindow.btoa(unescape(encodeURIComponent(s)))}
</script>
</body>
</html>
四、js实现Tab转为Excel
<!DOCTYPEhtml>
<htmllang="en">
<head>
<metacharset="UTF-8">
<metaname="viewport"content="width=device-width,initial-scale=1.0">
<metahttp-equiv="X-UA-Compatible"content="ie=edge">
<title>excel导出测试</title>
<style>
table{
border-collapse:collapse;
text-align:center;
vertical-align:middle;
width:800px;
font-size:20px;
}
button{
height:30px;
width:100px;
margin:20px20px;
background:yellowgreen;
border-radius:10px;
outline:none;
}
input{
height:30px;
padding-left:10px;
margin:10px;
}
</style>
</head>
<body>
<divid="wrap"style="width:900px;margin:20pxauto;">
<h3>js脚本导出excel测试</h3>
<tableid="tb"border="1"cellspacing="0"cellpadding="0">
<thead>
<tr>
<th>ID</th>
<th>姓名</td>
<th>年龄</td>

</tr>
</thead>
<tbody>
<tr>

<td>18</td>
<td>走的人多了，变成了路。</td>
</tr>
<tr>
<td>2</td>
<td>李四</td>
<td>88</td>
<td>人人都有自己走的路，哪条属于自己呢？</td>
</tr>
<tr>
<td>3</td>
<td>王五</td>
<td>81</td>
<td>走别人的路，让他没道可走！</td>
</tr>
</tbody>
</table>
<label>
姓名：<inputtype="text"autocompleteid="name"placeholder="请输入您的姓名...">

<label>
年龄：<inputtype="text"autocompleteid="age"placeholder="请输入您的年龄...">

<label>
座右铭：<inputtype="text"autocompleteid="sex"placeholder="请输入您的座右铭...">
</label>
<buttonid="add">添加信息</button>
<buttonid="out"onclick="btn_export()">导出文件</button>
</div>
<scriptsrc="./xlsx.core.min.js"></script>
<scriptsrc="./jquery.min.js"></script>
<scriptsrc="./excel.js"></script>
<script>
functionbtn_export(){
vartable=document.querySelector("#tb");
varsheet=XLSX.utils.table_to_sheet(table);//将一个table对象转换成一个sheet对象
openDownloadDialog(sheet2blob(sheet),'excel.xlsx');
}
varid=$("input").length+1;
$(function(){
$("#add").click(function(){
varname=$("#name").val();
varage=$("#age").val();
varsex=$("#sex").val();
$("tbody").append("<tr><td>"+id+"</td><td>"+name+"</td><td>"+age+"</td><td>"+sex+"</td></tr>");
id++;
$("input").val('');
});
})
</script>
</body>
</html>
