实现效果:
实现原理:
给关闭按钮绑定点击事件,点击以后触发动画效果。利用jQuery的animate方法,先让显示天气的盒子高度变为0,接着让整个包含天气和事件的盒子宽度变为0,最后通过将display属性值设为none,使得close按钮消失。
实现代码:
<!DOCTYPE html> <html> <head> <title>仿360开机效果</title> <meta charset="utf-8"> <style type="text/css"> *{ padding: 0; margin: 0; } .box{ width: 320px; position: fixed; bottom: 0; right: 0; box-shadow: 1px 1px 10px #2d2d2d; } #close{ position: absolute; top: 0; right: 0; width: 30px; height: 20px; cursor: pointer; background-color: red; color: pink; font-weight: bold; text-align: center; } .hd{ width: 320px; height: 300px; background-color: #03c03c; color: #fff; font-size: 70px; line-height: 300px; text-align: center; } .bd{ width: 320px; height: 100px; background-color: #fffc00; font-size: 30px; line-height: 100px; text-align: center; } </style> </head> <body> <div class="box"> <span id="close">X</span> <div class="hd" id="t">1分12秒</div> <div class="bd" id="b">天气:晴天</div> </div> <!-- 引入jQuery --> <script type="text/javascript" src="./jquery1.0.0.1.js"></script> <script type="text/javascript"> window.onload = function(){ var close = document.getElementById("close"); var box = close.parentNode; var b = document.getElementById("b"); // 给关闭按钮绑定点击事件 close.onclick = function(){ animate(b, {"height":0}, function(){ animate(box,{"width":0}); }); close.style.display = "none"; } } </script> </body> </html>
PS:JS 实现时间倒计时
<script type="text/javascript"> var maxtime = 1350057600 //截止到的日期 var now=parseInt((new Date().getTime())/1000);//获取当前的日期 var cha_time=maxtime-now;//中间所差的时间
下面方法把相差的时间组合成倒计时的字符串,然后放到页面相应位置实现,实时刷新
function CountDown(){ if(cha_time>=0){ var day = Math.floor(cha_time/3600/24); var hour= Math.floor((cha_time/3600)%24); var minutes = Math.floor((cha_time/60)%60); var seconds = Math.floor(cha_time%60); msg = "离结束还有"+day+"天"+hour+"小时"+minutes+"分"+seconds+"秒"; $(".ws_sg_con_big,.ws_sg_con_small").find("dd").html(msg); --cha_time; } else{ clearInterval(timer); alert("时间到,结束!"); } } timer = setInterval("CountDown()",1000); </script>
