列出些常用的javascript,大家可以把这些做成一个类,方便在项目中重复的调用。

至于怎么做,Blog已有介绍,我就不多说了。

欢迎大家补充^_^



1.让文字不停地滚动

  <MARQUEE>滚动文字</MARQUEE>

2.记录并显示网页的最后修改时间

  <script language=javascript>
  document.write("最后更新时间: " + document.lastModified + "")
  </script>

3.关闭当前窗口

  <a href="/"onClick="javascript:window.close();return false;">关闭窗口</a>

4.5秒后关闭当前页

  <script language="javascript">
  <!--
  setTimeout('window.close();',5000);
  -->
  </script>

5.2秒后载入指定网页

  <head>
  <meta http-equiv="refresh" content="2;URL=http://你的网址">
  </head>

6.添加到收藏夹

  <Script Language="javascript">
  function bookmarkit()
  {
  window.external.addFavorite('http://你的网址','你的网站名称')
  }
  if (document.all)document.write('<a href="#" onClick="bookmarkit()">加入收藏夹</a>')
  </Script>

7.让超链接不显示下划线

  <style type="text/css">
  <!-
  a:link{text-decoration:none}
  a:hover{text-decoration:none}
  a:visited{text-decoration:none}
  ->
  </style>

8.禁止鼠标右键的动作

  <Script Language = "javascript">
  function click() { if (event.button==2||event.button==3)
  {
  alert('禁止鼠标右键');
  }
  document.onmousedown=click // -->
  </Script>

9.设置该页为首页

  <body bgcolor="#FFFFFF" text="#000000">
  <!-- 网址:http://你的网址-->
  <a class="chlnk" style="cursor:hand" HREF
  onClick="this.style.behavior='url(#default#homepage)';
  this.setHomePage('你的网站名称);"><font color="000000" size="2" face="宋体">设为首页</font></a>
  </body>

10.节日倒计时

  <Script Language="javascript">
  var timedate= new Date("December 25,2003");
  var times="圣诞节";
  var now = new Date();
  var date = timedate.getTime() - now.getTime();
  var time = Math.floor(date / (1000 * 60 * 60 * 24));
  if (time >= 0)
  document.write("现在离"+times+"还有: "+time +"天")</Script>

11.单击按钮打印出当前页

  <Script Language="javascript">
  <!-- Begin
  if (window.print) {
  document.write('<form>'
  + '<input type=button name=print value="打印本页" '
  + 'onClick="javascript:window.print()"></form>');
  }
  // End -->
  </Script>

12.单击按钮‘另存为’当前页

  <input type="button" name="Button" value="保存本页"
  onClick="document.all.button.ExecWB(4,1)">
  <object id="button"
  width=0
  height=0
  classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2">
  <embed width="0" height="0"></embed>
  </object>

13.显示系统当前日期

  <script language=javascript>
  today=new Date();
  function date(){
  this.length=date.arguments.length
  for(var i=0;i<this.length;i++)
  this[i+1]=date.arguments }
  var d=new date("星期日","星期一","星期二","星期三","星期四","星期五","星期六");
  document.write(
  "<font color=##000000 style='font-size:9pt;font-family: 宋体'> ",
  today.getYear(),"年",today.getMonth()+1,"月",today.getDate(),"日",
  d[today.getDay()+1],"</font>" );
  </script>

14.不同时间段显示不同问候语

  <Script Language="javascript">
  <!--
  var text=""; day = new Date( ); time = day.getHours( );
  if (( time>=0) && (time < 7 ))
    text="夜猫子,要注意身体哦! "
  if (( time >= 7 ) && (time < 12))
    t
