JQuery动态生成的按钮无法触发问题及完美解决方法

//在网页加载完成后动态添加表格
$(function () {
    //通过Ajax向后台请求程序
   $.ajax({
     method : "post",
     url : "all-user",
     dataType : "json",
       success: function (data) {
           const userList = data;
	//遍历结果集
           for (let i = 0; i < userList.length; i++){
               let uid = userList[i].uid
               let upd = '<button value="'+uid+'" class="upd-btn">修改</button>'
               let del = '<button value="'+uid+'" class="del-btn">删除</button>'
               let status = ""
               if (userList[i].status == 0){
                   status = "审核中"
               }else if (userList[i].status == 1){
                   status = "审核通过"
               }else if (userList[i].status == 2){
                   status = "审核被拒绝"
               }
		//添加模板
               let td = "<tr>"+
               "<td>#{uid}</td>"+
               "<td>#{username}</td>"+
               "<td>#{password}</td>"+
               "<td>#{status}</td>"+
               "<td>#{update}</td>"+
               "<td>#{delete}</td>"+
               "</tr>"
		//填充参数
               td = td.replace(/#{uid}/g,uid)
               td = td.replace(/#{username}/g,userList[i].username)
               td = td.replace(/#{password}/g,userList[i].password)
               td = td.replace(/#{status}/g,  status)
               td = td.replace(/#{update}/g,  upd)
               td = td.replace(/#{delete}/g,  del)
               //.append追加
               $("#tb").append(td)
            }
       }
   })
    //编写按钮的点击事件,使用.click()方法,按钮点击后没有反应
  $(".del-btn").click(function () {
	  alert(this.value)
  })
 })

$(document).on("click",".del-btn",function (){
     
 })

$('.liLabel').live('click', function(){
alert('OK');
});

$("#ulLabel").on('click','.liLabel',function(){
alert('OK')
});
或者：
$("body").on('click','.liLabel',function(){
alert('OK')
});
