js导出excel:前端当前数据的导出

时间:2025-04-17 20:33:43
网上找的库文件,同样做了修改。在导出的时候,有时候数据第一列和最后一列可能是复选框和操作按钮,这个是我们不需要的,加了这个的过滤

前端页面的样子

<div class="layui-row">
<table class="layui-table"
lay-data="{url:'/student/student/oneListJson', page:true, id:'idTable', limit: 10}"
lay-filter="mtable">
<thead>
<tr>
<th lay-data="{checkbox:true, fixed: true}"></th>
<th lay-data="{templet:'#studentName'}">#(i18n.get('学生姓名'))</th>
<th lay-data="{field:'studentEnglishName'}">#(i18n.get('英文姓名'))</th>
<th lay-data="{field:'birthDateStr'}">#(i18n.get('出生日期'))</th>
<th lay-data="{templet:'#sex'}">#(i18n.get('性别'))</th>
<th lay-data="{field:'originalSchool'}">#(i18n.get('就读学校'))</th>
<th lay-data="{field:'campusName'}">#(i18n.get('所属校区'))</th>
<th lay-data="{field:'remarks'}">#(i18n.get('备注'))</th>
<th lay-data="{width:60, templet: '#status'}">#(i18n.get('状态'))</th>
</tr>
</thead>
</table>
</div> layui的数据表格也可以使用的,简单table也可以使用的 <button type="button" class="layui-btn layui-btn-primary layui-btn-sm" id="export_excel">导出本页数据</button>

使用方式

<!-- 导出 -->
<script type="text/javascript" src="/assets/layui-v2.4.3/table2excel.js"></script>
<script type="text/javascript" src="/assets/layui-v2.4.3/table2excels.js"></script>
<script>
//导出Excel
$("#export_excel").on('click', function() { $(".layui-table-box").table2excel({
exclude: ".noExl",
filename: "myFileName" + new Date().toISOString().replace(/[\-\:\.]/g, ""),
fileext: ".xls",
exclude_img: true,
exclude_links: true,
exclude_inputs: true,
sheetName: "student",
excludeFirst:true,
       excludeFirst:false
        });
});
</script>

最近找到一个新的导出插件

http://www.htmleaf.com/jQuery/Table/201605113452.html

js导出excel:前端当前数据的导出
第一个完美,后几个有不同的问题,第二打开时候会提示文件损坏或者格式问题,后边有的是编码问题,乱码
不过改改还是很不错的插件,最开始上边自己找的,也是打开回报文件损坏或者后缀有问题等。
现在这个插件第一个打开导出都是没有问题的。赞一个! 使用
