我无法移动项目的国家/地区,当前位置和最后位置以及第一位置。但是将元素上下移动是正确的。
我的HTML:
$(".item").append("<p><button class='down'>down↓</button><button class='up'>up↑</button><button class='first'>Move First</button><button class='last'>Move last</button></p>");
$(document).on("click",".up",function() {
var ob = $(this).closest('.item');
ob.insertBefore(ob.prev());
});
$(document).on("click",".down",function() {
var ob = $(this).closest('.item');
ob.insertAfter(ob.next());
});
$(document).on("click",".first",function() {
var ob = $(this).closest('.item');
ob.insertAfter(ob.prepend());
});
$(document).on("click",".last",function() {
var ob = $(this).closest('.item');
ob.insertAfter(ob.append());
});
我的Javascript / jQuery:
inst/rstudio/connections/
我的jsFiddle:
this operator has not been explicitly implemented
我在做什么错了?

我将.prependTo()和.appendTo()用于传递给他父母的目标物品上,以实现您的期望。这是我先移动/后移动的代码。
$(document).on("click",".first",function() {
var ob = $(this).closest('.item');
ob.prependTo(ob.parent());
});
$(document).on("click",".last",function() {
var ob = $(this).closest('.item');
ob.appendTo(ob.parent());
});

以下更改对我来说很好:
$(document).on("click",".first",function() {
var ob = $(this).closest('.item');
ob.insertBefore($(".item").first());
});
$(document).on("click",".last",function() {
var ob = $(this).closest('.item');
ob.insertAfter($(".item").last());
});

使用正确的选择器修正目标。
$(document).on("click",".first",function() {
var ob = $(this).closest('.item');
ob.insertBefore($('.item:first'));
});
$(document).on("click",".last",function() {
var ob = $(this).closest('.item');
ob.insertAfter($('.item:last'));
});

我的建议是:
最后移动:append()到您的 ListCountries
$(document).on(“ click”,“。first”,function(){ //从头开始 var ob = $(this).closest('。ListCountries'); ob.prepend($(this).closest('。item')); });
$(document).on(“ click”,“。last”,function(){ //最后移动 var ob = $(this).closest('。ListCountries'); ob.append($(this).closest('。item')); });
$(".item").append("<p><button class='down'>down↓</button><button class='up'>up↑</button><button class='first'>Move First</button><button class='last'>Move last</button></p>");
$(document).on("click",".up",function() {
var ob = $(this).closest('.item');
ob.insertBefore(ob.prev());
});
$(document).on("click",".down",function() {
var ob = $(this).closest('.item');
ob.insertAfter(ob.next());
});
$(document).on("click",".first",function() {
var ob = $(this).closest('.ListCountries');
ob.prepend($(this).closest('.item'));
});
$(document).on("click",".last",function() {
var ob = $(this).closest('.ListCountries');
ob.append($(this).closest('.item'));
});
.item{
width: 400px;
height: 60px;
background-color: #FFEEAA;
border: 2px dotted Orange;
border-radius: 7px;
padding: 7px;
margin-bottom: 7px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="ListCountries">
<div class="item">Argentina</div>
<div class="item">Bolivia</div>
<div class="item">Brasil</div>
<div class="item">Chile</div>
<div class="item">Colombia</div>
<div class="item">Ecuador</div>
<div class="item">Paraguay</div>

尝试一下:
$(".item").append("<p><button class='down'>down↓</button><button class='up'>up↑</button><button class='first'>Move First</button><button class='last'>Move last</button></p>");
$(document).on("click",".up",function() {
var ob = $(this).closest('.item');
ob.insertBefore(ob.prev());
});
$(document).on("click",".down",function() {
var ob = $(this).closest('.item');
ob.insertAfter(ob.next());
});
$(document).on("click",".first",function() {
var ob = $(this).closest('.item');
ob.parent().prepend(ob);
});
$(document).on("click",".last",function() {
var ob = $(this).closest('.item');
ob.parent().append(ob);
});
