JavaScript教程之文字特殊效果
JavaScript教程之文字特殊效果 特效一:滚动显示。 被过滤广告。 第一步:把如下代码加入《 head》区域中。 《 script language=“Javascript”》 《 !-- function scrollit(seed) { var m1 = “HI:你好! ”; var m2 = “欢迎访问多特”; var m3 = “请多提意见,谢谢! ”; var m4 = “欢迎您下次再来!”; var m5 = “www.duote.com ”; var msg=m1+m2+m3+m4+m5; var out = “ ”; var c = 1; if (seed 》 100) { seed--; cmd=“scrollit(”+seed+“)”; timerTwo=window.setTimeout(cmd,100); } else if (seed 《 = 100 && seed 》 0) { for (c=0 ; c 《 seed ; c++) { out+=“ ”; } out+=msg; seed--; window.status=out; cmd=“scrollit(”+seed+“)”; timerTwo=window.setTimeout(cmd,100); } else if (seed 《 = 0) { if (-seed 《 msg.length) { out+=msg.substring(-seed,msg.length); seed--; window.status=out; cmd=“scrollit(”+seed+“)”; timerTwo=window.setTimeout(cmd,100); } else { window.status=“ ”; timerTwo=window.setTimeout(“scrollit(100)”,75); } } } //--》 《 /script》 第二步:把如下代码加入《 body》区域中 《 body background=bag.gif onLoad=“scrollit(100)”》 特效二:文字从状态栏的右边循环弹出 把如下代码加入《 head》区域中 《 script language=“Javascript”》 var MESSAGE = “欢迎来到多特网,请多提意见。谢谢! ” var POSITION = 150 var DELAY = 10 var scroll = new statusMessageObject() function statusMessageObject(p,d) { this.msg = MESSAGE this.out = “ ” this.pos = POSITION this.delay = DELAY this.i = 0 this.reset = clearMessage} function clearMessage() { this.pos = POSITION} function scroller() { for (scroll.i = 0; scroll.i 《 scroll.pos; scroll.i++) { scroll.out += “ ”} if (scroll.pos 》= 0) scroll.out += scroll.msg else scroll.out = scroll.msg.substring(-scroll.pos,scroll.msg.length) window.status = scroll.out scroll.out = “ ” scroll.pos-- if (scroll.pos 《 -(scroll.msg.length)) { scroll.reset()} setTimeout (‘scroller()’,scroll.delay)} function snapIn(jumpSpaces,position) { var msg = scroll.msg var out = “” for (var i=0; i《 position; i++) {out += msg.charAt(i)} for (i=1;i《 jumpSpaces;i++) {out += “ ”} out += msg.charAt(position) window.status = out if (jumpSpaces 《 = 1) { position++ if (msg.charAt(position) == ‘ ’) {position++ } jumpSpaces = 100-position } else if (jumpSpaces 》 3) {jumpSpaces *= .75} else {jumpSpaces--} if (position != msg.length) { var cmd = “snapIn(” + jumpSpaces + “,” + position + “)”; scrollID = window.setTimeout(cmd,scroll.delay); } else { window.status=“” jumpSpaces=0 position=0 cmd = “snapIn(” + jumpSpaces + “,” + position + “)”; scrollID = window.setTimeout(cmd,scroll.delay); return false } return true} snapIn(100,0); 《 /script》
