JS,浏览器,状态栏文字,弹出效果本文实例讲述了JS实现浏览器状态栏文字从右向左弹出效果。分享给大家供大家参考，具体如下： 这里状态栏文字弹出代码，从右向左弹出，通过修改Script中的这些代码片段可改变效果： var POSITION = 100
var DELAY = 4
var MESSAGE = "这里是你想要的文字！" 运行效果截图如下： 
在线演示地址如下： http://demo.wanshiok.com/js/2015/js-status-bar-txt-scroll-codes/ 具体代码如下： <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"><HTML><HEAD><TITLE>状态栏文字弹出代码，从右向左弹出</TITLE></HEAD><BODY><script language="JavaScript"> <!--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}var POSITION = 100var DELAY = 4 var MESSAGE = "状态栏文字快速的一个一个弹出！！！ " var scroll = new statusMessageObject()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></BODY></HTML>希望本文所述对大家JavaScript程序设计有所帮助。
