本文实例讲述了JS实现的打字机效果。分享给大家供大家参考,具体如下:
<!DOCTYPE html><html lang="en"><head><meta charset="utf-8"><!-- Always force latest IE rendering engine (even in intranet) & Chrome FrameRemove this if you use the .htaccess --><meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"><title>JS打字机效果</title><meta name="description" content=""><meta name="author" content="Administrator"><meta name="viewport" content="width=device-width; initial-scale=1.0"><!-- Replace favicon.ico & apple-touch-icon.png in the root of your domain and delete these references --><style type = "text/css"> #main {width: 80%;height: 750px;margin: auto;padding: 10px;background: #cfe1ca;border: 10px outset #f9c6aa;line-height: 30px;color: #9f3c61;font-size: 18px; } p {text-indent: 30px; }</style><script type = "text/javascript"> var typeWriter = {msg: function(msg){ return msg;},len: function(){ return this.msg.length;},seq: 0,speed: 150,//打字时间(ms)type: function(){ var _this = this; document.getElementById("main").innerHTML = _this.msg.substring(0, _this.seq); if (_this.seq == _this.len()) {_this.seq = 0; clearTimeout(t); } else {_this.seq++;var t = setTimeout(function(){_this.type()}, this.speed); }} } window.onload = function(){alert("welcome to http://www.jb51.net")var msg = "JS打字机效果 ,原理很简单:每次多获取一个待打出的字符串的值,输出,覆盖原来输出的内容即可";function getMsg(){ return msg;}typeWriter.msg = getMsg(msg);typeWriter.type(); }</script> </head> <body><div id = "main"> </div> </body></html>更多关于JavaScript相关内容感兴趣的读者可查看本站专题:《JavaScript切换特效与技巧总结》、《JavaScript查找算法技巧总结》、《JavaScript动画特效与技巧汇总》、《JavaScript错误与调试技巧总结》、《JavaScript数据结构与算法技巧总结》、《JavaScript遍历算法与技巧总结》及《JavaScript数学运算用法总结》
