js前端导出excel：json形式的导出
生活随笔
收集整理的這篇文章主要介紹了
js前端导出excel：json形式的导出
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
第一中形式的導出：主要是表頭對應主體數據，json形式的導出
js庫文件名稱 ： table2excel.js
這個js庫文件是網上找的，并且自己根據自己業務需求把內容改了一下
復制到 table2excel.js 文件中，作為自己的js庫，就可以使用。記得先引入jq的庫

?
調整后的代碼，把并發的問題修改了。師兄幫助修改的。自己是沒有發現的var App ={//導出excel時候，把頁面的數據分裝到一個json數組中，然后使用layui的導出方法導出數據exportExcel : function (url, excelTitleJson, excelName, data, settings) {if(typeof(data) == "undefined" || data == null){console.log("查詢條件為空");data = JSON.parse("{}");}if(! settings){settings = {//頁數pageInt : 1,//每次限制10條limit : 10,//拿到的數據json進行封裝到arr數組中 arr : []}}data["page"] = settings.pageInt;$.getJSON(url, data, function(json){if(json.data.length <= 0){//沒有查到數據,不導出if(settings.arr.length > 0){//table.exportFile([],settings.arr , 'xls'); //默認導出 csv，也可以為：xls $(".layui-table-box").table2excel({//exclude: ".noExl",filename: excelName + new Date().toISOString().replace(/[\-\:\.]/g, ""),fileext: ".xls",sheetName: "sheet",excludeFirst:true,excudeLast:true,dataList:settings.arr,dataTitle:excelTitleJson});//導出后這個頁數,初始化page:settings.pageInt = 1;}}else{for(var i = 0;i<json.data.length;i++){settings.arr.push(json.data[i]);}settings.pageInt++;data["page"] = settings.pageInt;//有數據,就再次執行拿數據，回調 App.exportExcel(url, excelTitleJson, excelName, data, settings);}});} }
?

?
最后就是使用了
?
App.exportExcel("/YunApps/com_momathink_crm_zkhq/customer/myCustomerList",{"followStatus":"狀態"}, //這里需要填寫的是excel導出后的表頭，key就是數據庫查詢出的json數據的每條數據的key，value就是表頭，每個表頭會對應上它的值
"客戶信息",//導出excel的名字
{}//最后一個參數可填可不填 );
