如图，前台的样子，data的参数为

[{"good_id":1,"good_name":"标样-总磷","good_num":"BY400014","pid":10,"first_pid":1,"good_standard":"1.46mg/L","good_cas":"7220-81-7","good_spe":"1mL","normal_price":"500.00","good_stock":"322","good_indate":"1600876800","cash_sale":"1","good_url":"/uploads/20190923/eaa8577dd76344a3ed15cc3ca0146a50.jpg","company":"TMstandard","good_sort":99,"good_new":1,"good_promotion":1,"create_time":"1569222082"},{"good_id":2,"good_name":"水中甲醛(HJ601-2011水质甲醛的测定乙酰","good_num":"BW20040-100-W-20","pid":14,"first_pid":2,"good_standard":"100mg/L","good_cas":"50-00-0","good_spe":"20mL","normal_price":"90.00","good_stock":"280","good_indate":"1630512000","cash_sale":"1","good_url":"/uploads/20190923/8ca481784cc15ee27399e754d788aad1.jpg","company":"坛墨质检","good_sort":99,"good_new":1,"good_promotion":1,"create_time":"1569222248"}]

大概就是要批量删除两条记录，然后死活无法传值到后台，传过去返回一看就是undefined，卡了一上午！！！！

最后解决，之后就能获取到传的值了{"id":["1","2"]}，当然这里使用json_encode尽心json处理了

var data = checkStatus.data; var id = new Array();//这里还有个小插曲，创建空数组时，必须使用Array、array就会报错，笑哭了，底子不牢固啊 console.log(JSON.stringify(data)); for(var i in data){ id[i] = data[i].good_id; } $.ajax({ url:'',//后台控制器 type:'post', data:{ 'id':id }, dataType:'json', success:function (msg) { console.log(msg); } });　

以上这篇解决layui批量传值到后台操作时出现传值为空的问题就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
