Question

问题是，当我点击delaccbut按钮时，点击功能会起作用并显示消息，但当我点击点击功能中的confdel或redel按钮时，不......为什么？

HTML:

<span id='delaccspan'>
<button class='defbutt' id='delaccbut'>Delete my account</button>
</span>

jQuery:

$(document).ready(function(){
    $("#delaccbut").click(function(){
        $("#delaccspan").html("All your posts, pictures, followers and everything you did on this page will be deleted. Do you want to continue? <button class='smallbut' id='confdel'>Yes</button> <button class='smallbut' id='redel'>No</button>");
    });
    $("#confdel").click(function(){
        $("#delaccspan").html("Okay");
    });
    $("#redel").click(function(){
        $("#delaccspan").html("Good decision!");
    });
});

这里有什么问题？谢谢！

初始化脚本时，yes和no按钮不存在。您需要将事件委托给父母，以便它可以应用于现在或将来存在的特定儿童。

请参阅：http://learn.jquery.com/events/event-delegation/

$(function(){
    $("#delaccbut").click(function(){
        $("#delaccspan").html("All your posts, pictures, followers and everything you did on this page will be deleted. Do you want to continue? <button class='smallbut' id='confdel'>Yes</button> <button class='smallbut' id='redel'>No</button>");
    });

    $("body").on("click", "#confdel", function(){
        $("#delaccspan").html("Okay");
    });

    $("body").on("click", "#redel", function(){
        $("#delaccspan").html("Good decision!");
    });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<span id='delaccspan'>
<button class='defbutt' id='delaccbut'>Delete my account</button>
</span>

click（）函数中的click（）函数不起作用
