分享一段将json数组数据以csv格式导出的代码:

html:

<button class="btn btn-danger" @click='exportData'>导出</button>

js:

// 导出数据 exportData: function() { let tableHeader = [{ colname: 'type', coltext: '类型', }, { colname: 'name', coltext: '商品名称', }, { colname: 'number', coltext: '数量', }, { colname: 'price', coltext: '单价', }]; let tableBody = [{ type: '食品', name: '旺旺雪饼', number: '100箱', price: '25元/袋' }, { type: '食品', name: '双汇火腿', number: '50箱', price: '5元/根' }, { type: '食品', name: '毛毛虫面包', number: '10箱', price: '3元/袋' }, { type: '食品', name: '阿尔卑斯棒棒糖', number: '10箱', price: '0.5元/个' }, { type: '食品', name: '蒙牛酸奶', number: '20箱', price: '12.9元/瓶' }, { type: '水果', name: '香蕉', number: '10斤', price: '2.5元/斤' }, { type: '水果', name: '葡萄', number: '20斤', price: '4元/斤' }, { type: '水果', name: '榴莲', number: '10斤', price: '24元/斤' }, { type: '水果', name: '李子', number: '20斤', price: '4元/斤' }]; var csv = '\ufeff'; var keys = []; tableHeader.forEach(function(item) { csv += '"' + item.coltext + '",'; keys.push(item.colname); }); csv = csv.replace(/\,$/, '\n'); tableBody.forEach(function(item) { var _item = {}; keys.forEach(function(key) { csv += '"' + item[key] + '",'; }); csv = csv.replace(/\,$/, '\n'); }); csv = csv.replace(/"null"/g, '""'); var blob = new Blob([csv], { type: 'text/csv,charset=UTF-8' }); var csvUrl = window.URL.createObjectURL(blob); var a = document.createElement('a'); var now = new Date(); function to2(num) { return num > 9 ? num : '0' + num; } a.download = '进货信息导出' + now.getFullYear() + to2((now.getMonth() + 1)) + to2(now.getDate()) + to2(now.getHours()) + to2(now.getMinutes()) + to2(now.getSeconds()) + '.csv'; a.href = csvUrl; document.body.appendChild(a); a.click(); document.body.removeChild(a); }
