javascript - Jquery，无法删除克隆的元素

Question

当我尝试在我的 jquery 代码中使用克隆方法时，我遇到了一些问题。 我在这里列出了我想要的和我面临的问题。

首先让我告诉我我想要什么，我希望当我点击添加按钮时，我的代码应该克隆给 id 的元素和删除按钮的数据。 ( JS Fiddle )

这是我的代码:HTML

<table class="cloneelementtable">
    <tr>
        <td>
            <div class="priceandsize1row">&nbsp;</div>
        </td>
        <td>
            <div class="priceandsize2row">&nbsp;</div>
        </td>
        <td>
            <div class="priceandsize3row">&nbsp;</div>
        </td>
        <td>
            <div class="priceandsize4row">&nbsp;</div>
        </td>
        <td>
            <div class="priceandsize5row">&nbsp;</div>
        </td>
        <td>
            <div class="priceandsize6to9row">&nbsp;</div>
        </td>
        <td>
            <div class="priceandsize6to9row">&nbsp;</div>
        </td>
        <td>
            <div class="priceandsize6to9row">&nbsp;</div>
        </td>
        <td id="divaddmore">

代码在这里:JQ

var id = 0;
$(document).ready(function () {
    $('#todoclone').click(function () {
        $('#cloneelement').clone().appendTo(".cloneelementtable");
        id++;
    });

    /*$('#toremoveclone').click(function() {
               $('#cloneelement').closest('#cloneelement').fadeOut("slow", function(){
             $(this).remove();
              });
            });*/
    $("#toremoveclone").click(function () {
        console.log(id);
        if (id > 1) { //Only apply if the lang field is more than 1
            id = id - 1;
            $("#cloneelement:last").remove();
            console.log(id);
        }
    });
});

我对此进行了一些搜索并编写了类似的代码(此处的代码:JS Fiddle )

但是代码中有一些问题，(如下所列) 1] 我无法删除克隆的元素，我需要在列表中克隆它 3 次，然后当我单击第一个减号图标时它只删除一次。之后我无法删除更多内容。

谁能告诉我如何解决这类问题？

即单击加号按钮进行克隆，然后单击删除按钮删除克隆。

问题出在您的 $("#toremoveclone").click(...) 绑定(bind)上。 你错过了一些东西。这是 working fiddle .

问题:

• ID 应该是唯一的。
• 您期望事件委托(delegate)，但没有进行设置。
• $("#toremoveclone").click(...) 仅将点击事件绑定(bind)到第一个 #toremoveclone。
• 检查添加超过 2 个克隆(您的代码需要超过 1 个克隆才能删除一个)并删除您的 fiddle 中的第一个。 .
• 它将被删除。但其他人不会，因为他们没有绑定(bind)到任何点击事件。

我所做的更改:

• 为 div 添加了一个类(toremoveclone)。

• 将事件绑定(bind)更改为

  $(".cloneelementtable").on('click', '.toremoveclone', function () {..})

• 在 here 中了解有关 Jquery 事件委托(delegate)的更多信息& here ，因为如果我解释，我可能会搞砸 :(
