// 全部删除
$(".delAll").click(function () {$.get("/delAll", function (res) {if (res.code == 200) {$(".showDiv").html("");console.log("全部删除成功");} else {alert(res.msg);}})
})

1-2全部删除的接口

app.get("/delAll", handleData.getDelAll);

1-3全部删除的handleData.js

module.exports.getDelAll = function (req, res) {db.drop(res, "case1110", function (err, result, db1) {if (err) {res.send({ code: 404, msg: "全部删除失败" });} else {res.send({ code: 200, msg: "全部删除成功" });db1.close();}})
}

2-1修改---index.js

渲染中的button按钮
function uptFn (id) {$.get("/uptShow", { id }, function (res) {if (res.code == 200) {var obj = res.obj[0];$(".user").val(obj.user);$(".age").val(obj.age);uptId = id;} else {alert(res.msg);}})
