JQuery可拖放功能无法正常工作

我想创建一个应用程序，使用jquery库将某些元素拖放到其他元素上。可拖动的功能似乎可以正常工作，但是落下的功能不起作用。我尝试为可拖动和可落下的元素分配id，因为这解决了某个人的问题（该人的问题是库的问题），这与我的问题类似。 我使用了从此处获取的jquery库和js（修改后嵌入html文档中，并在其代码下列出）：http://superdit.com/2011/04/02/drag-drop-shopping-cart-using-jquery/。我再次强调，除了落下的功能外，一切都正常运行。
任何帮助都将是极好的！谢谢！
（以下是包含js和css的html代码）

你能否在http://www.jsfiddle.net上创建一个小的演示来复制你遇到的问题？ - Andrew Whitaker

您的两个可拖动处理程序之间存在不一致性，在第二个处理程序的最后一行中，您使用了类选择器“.down_spin”，而其他地方都使用了id选择器“#down_spin”。

另一个大问题是您的文档中不应该有两个具有相同id的DOM元素，请尝试将所有的up_spin和down_spin元素更改为这些名称的类，并将您的id选择器更改为类选择器。请确保根据上述规则决定您想要使用类还是id，因为您在静态标记中使用id，在可放置处理程序的html注入中使用类。

此外，在down_spin可拖动处理程序中，从您的html字符串连接中删除''位，您没有在up_spin处理程序中使用它，并且它也不正确。

如果您正在使用jQuery，则最好始终保持一致，在所有地方使用它，将以下内容更改：

infoSelected.innerHTML = "Element: "+"<i>"+element[val.value]+"</i>"+"&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"+"Simbol: "+"<i>"+simbol[val.value]+"</i>";

to:

$(infoSelected).html("Element: "+"<i>"+element[val.value]+"</i>"+"&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"+"Simbol: "+"<i>"+simbol[val.value]+"</i>");

在所有这些清理工作完成后，它可能会神奇地开始工作。

非常感谢您，DarthJDG！我已经按照您的建议进行了所有更改。现在它可以正常工作了！ - zxcvbnm
