【油猴脚本】00019 案例 Tampermonkey油猴脚本, 仅用于学习,不要乱搞。添加数据导出Excel功能。Jquery爬虫,JavaScript爬虫,HTML+Css+JavaScript编写
使用的库:
Bootstrap的Css库CDN:
https://apps.bdimg.com/libs/bootstrap/3.3.4/css/bootstrap.css
Jquery库CDN:
https://code.jquery.com/jquery-1.9.1.min.js
sheetjs库CDN:
https://cdn.sheetjs.com/xlsx-0.20.1/package/dist/xlsx.full.min.js
Jquery的库easyuijs CDN:
https://www.jeasyui.com/easyui/jquery.easyui.min.js
?一、效果
把当前页的数据导出到Excel
导出后的Excel
?二、核心解析
?1.添加sheetjs库:
// @require https://cdn.sheetjs.com/xlsx-0.20.1/package/dist/xlsx.full.min.js
?2.添加导出Excel
按钮:
<button id="outExcel" class="btn btn-default">导出Excel</button>
?3.添加点击事件:
// 点击-导出Excel $("#outExcel").click(function(){ let obj = { htmlElementTable: '#test_table', excelSaveName: '获取的数据' } htmlTableToExcel(obj) })
?4.添加导出Excel的函数:
function htmlTableToExcel(objOptions){ if(!objOptions){ alert("请填写函数调用参数") return false; } let opt = objOptions; // opt.htmlElementTable 需要转化的htmlTable // opt.excelSaveName 导出的表格名称 // 1、寻找表格元素 let html_table = document.querySelector(`${opt.htmlElementTable}`) // 2、创建新的工作簿 const wb = XLSX.utils.book_new() // 3、将表格元素转sheet表格 const worksheet = XLSX.utils.table_to_sheet(html_table) // 4、将sheet表添加到工作簿 XLSX.utils.book_append_sheet(wb, worksheet, "Sheet1"); // 5、保存工作簿 XLSX.writeFile(wb, `${opt.excelSaveName}.xlsx`) }
?三、完整源代码,可以直接复制使用

?四、使用此代码的方法:
1.浏览器打开https://developer.mozilla.org/zh-CN/
2.把代码复制进油猴脚本,打开运行开关,刷新页面
