JS的属性好多,方法好多,一下子塞进来真的需要时间消化,很多东西都是当时记得很清楚,但忘得很快,看来需要经常去复习,主要是感觉后面一点的练习题好像少了点,所以就显得不是很熟练.
1.About Time:
/*//输出今天的日期、星期、时间字符串 var today = new Date(); var year = today.getFullYear(); var month = today.getMonth(); var day = today.getDate(); var week = today.getDay(); var hours = today.getHours(); var minutes = today.getMinutes(); var seconds = today.getSeconds(); //定义前导0函数: function addZero(x){ return x<10 ? "0"+x : x; } arr_month = ["01月","02月","03月","04月","05月","06月","07月","08月","09月","10月","11月","12月"]; arr_week = ["星期天","星期一","星期二","星期三","星期四","星期五","星期六",]; var str = "今天是"+year+"年"+arr_month[month]+addZero(day)+"日"+arr_week[week]+addZero(hours)+"时"+addZero(minutes)+"分"+addZero(seconds)+"秒." document.write(str);*/
2.神奇的滚动框:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>滚动框</title> <style type="text/css"> *{ margin:0px; padding: 0px; } ul,li{ list-style: none; } #div1{ width:200px; height:250px; margin:100px auto; overflow: hidden; } li{ text-align:center; border-bottom: 1px dotted #ccc; } </style> <script type="text/javascript"> window.onload = function(){ //1.先找到对象 var div1 = document.getElementById("div1"); var div2 = document.getElementById("div2"); var div3 = document.getElementById("div3"); //2.将3个div的高度设置成一样 div2.style.height = div1.offsetHeight+"px"; div3.style.height = div1.offsetHeight+"px"; //3.给div3增加内容 div3.innerHTML = div2.innerHTML; //4.设置定时器动画 window.setInterval(scrolling, 40); } function scrolling(){ var div1 = document.getElementById("div1"); div1.scrollTop==div1.offsetHeight ? div1.scrollTop=0 : div1.scrollTop++; /*document.title=div1.scrollTop;*/ } </script> </head> <body> <div id="div1"> <div id="div2"> <ul> <li>龙珠</li> <li>海贼王</li> <li>死神</li> <li>火影忍者</li> <li>死亡笔记</li> <li>寄生兽</li> <li>吸血鬼日记</li> <li>暮光之城</li> <li>斯巴达克斯</li> <li>权力的游戏</li> <li>越狱</li> </ul> </div> <div id="div3"></div> </div> </body> </html>
