前言:jq的最后一节课,主要讲解应用,
内容:
1.会飞的li:
HTML代码:
1 <!DOCTYPE html> 2 <html xmlns="http://www.w3.org/1999/xhtml"> 3 <head> 4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> 5 <title>会飞的li</title> 6 <script src="js/jquery-1.10.2.min.js"></script> 7 <script src="js/demo1.js"></script> 8 <link href="css/css1.css" rel="stylesheet" /> 9 </head> 10 <body> 11 <ul id="u1"> 12 <li>Google</li> 13 <li>Facebook</li> 14 <li>Yahoo</li> 15 <li>Amazon</li> 16 <li>MSN</li> 17 <li>eBay</li> 18 </ul> 19 <ul id="u2"></ul> 20 </body> 21 </html>
CSS代码:
1 * { 2 padding: 0px; 3 margin: 0px; 4 font-family: "微软雅黑"; 5 } 6 ul { 7 list-style-type: none; 8 height: 210px; 9 width: 160px; 10 border: dashed 2px #00bfff; 11 line-height: 33px; 12 margin-top: 100px; 13 margin-left: 150px; 14 } 15 li { 16 margin-left: 45px; 17 } 18 #u1 { 19 float: left; 20 } 21 #u2 { 22 margin-right: 150px; 23 float: right; 24 }
JS代码:
1 $(function() { 2 $("li").click(function() { 3 if ($(this).parent().attr("id")=="u1") { 4 $(this).css("position", "absolute").animate({ "left": document.body.clientWidth - 265 }, 2000,function() { 5 $(this).appendTo($("#u2")).css("position","static"); 6 }); 7 } 8 else { 9 $(this).css("position", "absolute").animate({ "left": 150 }, 2000, function () { 10 $(this).appendTo($("#u1")).css("position", "static"); 11 }); 12 } 13 14 }); 15 });

2.消息弹框:
HTML代码:
1 <!DOCTYPE html> 2 <html xmlns="http://www.w3.org/1999/xhtml"> 3 <head> 4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> 5 <title>消息弹框</title> 6 <script src="js/jquery-1.10.2.min.js"></script> 7 <script src="js/demo2.js"></script> 8 <link href="css/demo2.css" rel="stylesheet" /> 9 </head> 10 <body> 11 <div id="message"><img src="image/message.jpg"/></div> 12 </body> 13 </html>
CSS代码:
1 * { 2 padding: 0px; 3 margin: 0px; 4 } 5 #message { 6 position: fixed; 7 right: 0px; 8 bottom: -203px; 9 }
JQ代码:
1 $(function() { 2 $("#message").animate({ "bottom": "0px" }, 2000,function() { 3 setTimeout(function() { 4 $("#message").animate({ "bottom": "-203px" }, 2000); 5 }, 5000); 6 }); 7 });

3.砸金蛋:
HTML代码:
