Recently, I want to use jQuery to create a tree directory structure for a web page, and you can use the mouse to drag and adjust the options. I found plug-ins on the Internet. I have read several well-known plug-ins. I think the code is too complicated or the interface is too ugly. Therefore, we still need to work on our own, or stick to the simple code style that is beautiful.

 



Demo
Try embedding a test page in iframe. You can drag the project with the mouse to adjust the category:

Of course, this is not the final effect I want. I can only say that it has achieved a drag-and-drop effect I want. On this basis, I want to add automatic sorting and restore the jQuery event of the element bind after the position change.
Code
The Code is as follows. to copy a file, check the plain text version first!
<! DOCTYPE html>
<Html>
<Head>
<Title> Drag & Drop Test </title>
<Meta http-equiv = "content-type" content = "text/html; charset = UTF-8">
<Script type = "text/javascript"
Src = "https://readself.com/static/js/jquery.min.js? V = 52337 "> </script>
<Script type = "text/javascript"
Src = "https://readself.com/static/js/jquery-ui.min.js? V = ab482 "> </script>
<Link rel = "stylesheet" type = "text/css"
Href = "https://readself.com/static/css/smoothness/jquery-ui.css? V = af3ef "/>
<Style type = "text/css">
Li {cursor: pointer}
. Menu_hover {background-color: # d0d0d0 ;}
# Menu p {margin: 5px 0 5px 0 ;}
</Style>
<Body>
<Ul id = "menu">
<Li class = "folder">
<P> Fruits </p>
<Ul>
<Li> Apple </li>
<Li> Pear </li>
<Li> Banana </li>
</Ul>
</Li>
<Li class = "folder"> <p> Vegetables </p>
<Ul>
<Li> Tomato </li>
<Li> Potato </li>
<Li> Cucumber </li>
</Ul>
</Li>
<Li class = "folder"> <p> Meet </p>
<Ul>
<Li> Beaf </li>
<Li> Pork </li>
<Li> Chicken </li>
</Ul>
</Li>
</Ul>

<Script>
$ ('# Menu li'). disableSelection ();
$ ('Lil', $ ('# menu ul'). draggable ({revert: 'invalid', helper: 'clone '});
$ ('# Menu. folder'). droppable ({
HoverClass: "menu_hover ",
Drop: function (event, ui ){
If (ui. draggable. parents ('. folder'). get (0) ==$ (this). get (0 ))
Return;
$ ('Ul ', this). append (ui. draggable. clone ());
Ui. draggable. remove ();
$ ('Lil', this). draggable ({remove: 'invalid', helper: 'clone '});
}
});
$ ('# Menu. folder p'). click (function (){
$ (This). next (). toggle ();
});
</Script>
I am still a newbie on the webpage. You are welcome to give me some advice !!!
