我怎样才能在下方添加两个按钮?第一个按钮会添加一个面板,第二个按钮会删除一个选定的面板吗?
我的想法是,如果我愿意的话,我可以拥有尽可能多的面板,并删除某些面板。

您可以在HTML中添加2个按钮并附加功能。
对于添加,它会将可拖动的div添加到您的身体。您必须使用ID而不是类来选择元素。
以下是添加可拖动div的代码:
<!DOCTYPE HTML>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<html lang="en">
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/jquery-ui.js"></script>
<link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.1/themes/base/jquery-ui.css"/>
<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
$("#add").click(function () {
$("body").append("<div class=\"drag panel panel-default\"><div class=\"panel-body\">Draggable & Sizable</div></div>" );
$(".drag").resizable({
stop: function(event, ui) {
var w = $(this).width();
var h = $(this).height();
}
}).draggable(
{
containment: $('body'),
drag: function(){
var offset = $(this).offset();
var xPos = offset.left;
var yPos = offset.top;
$('#posX').text('x: ' + xPos);
$('#posY').text('y: ' + yPos);
},
stop: function(){
var finalOffset = $(this).offset();
var finalxPos = finalOffset.left;
var finalyPos = finalOffset.top;
$('#finalX').text('Final X: ' + finalxPos);
$('#finalY').text('Final X: ' + finalyPos);
}
});
});
});
</script>
<style type="text/css">
.drag {
width: 16em;
height: 16em;
padding: 0.5em;
border: 3px solid #000;
background-color: #fff;
background-color: rgba(255,255,255,0.5);
}
</style>
</head>
<body>
<button id="add">Add</button>
<button id="hide">Hide</button>
</body>
</html>
