1. 拼接返回的json数据
// 拼接需要下载报表的HTML，并返回html;
reportHtml(reporttData) { let html = `<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"> <head><!--[if gte mso 9]> <meta http-equiv="Content-Type"" content="text/html;charset=utf-8" /> <style> .xl24 { mso-style-parent: style0; mso-number-format: "" \\@ ""; text-align: right; vnd . ms-excel . numberformat: @ } </style> <xml> <x:ExcelWorkbook> <x:ExcelWorksheets> <x:ExcelWorksheet> <x:Name>报表</x:Name> <x:WorksheetOptions> <x:DisplayGridlines/> </x:WorksheetOptions> </x:ExcelWorksheet> </x:ExcelWorksheets> </x:ExcelWorkbook> </xml><![endif]--></head> <body>` html += `<table><thead> <tr> <th>姓名</th> <th>性别</th> <th>备注</th> </tr> </thead><tbody>`; reporttData.forEach(item => { html += `<tr> <td>${item.name ? item.name : \'\'}</td> <td>${item.sex === \'1\' ? \'男\' : \'女\'}</td> <td>${item.IsVip === \'1\' ? \'会员\' : \'非会员\'}</td> <td>${item.msg? item.msg : \'\'}</td></tr>`; }) html += `</tbody></table></body></html>`; return html; }
2. 点击下载时下载报表
let html = this.reportHtml(response.data) var blob = new Blob([html], {type: "application/vnd.ms-excel;charset=utf-8"}); var objectUrl = URL.createObjectURL(blob); console.log(objectUrl) var a = document.createElement(\'a\'); document.body.appendChild(a); a.setAttribute(\'style\', \'display:none\'); a.setAttribute(\'href\', objectUrl); a.setAttribute(\'download\', \'fileName\'); a.click(); URL.revokeObjectURL(objectUrl);
