html部分
<div id="code">
<p>/**</p>
<p>*2014-2-12</p>
<p>*代码自动闪烁输入</p>
<p>*/</p>
2014-2-14,I want to say:<br />
Baby, I love you forever!<br />
</div>
js部分
function typewriter(id){
var $ele = document.getElementById(id);
var str = $ele.innerHTML, progress = 0;
$ele.innerHTML = '';
var timer = setInterval(function() {
var current = str.substr(progress, 1);
if (current == '<') {
progress = str.indexOf('>', progress) + 1;
} else {
progress++;
}
$ele.innerHTML =str.substring(0, progress) + (progress & 1 ? '_' : '');
if (progress >= str.length) {
clearInterval(timer);
}
}, 75);
}
使用方法: typewriter("code");
弄成个jquery插件
(function($) {
$.fn.typewriter = function() {
var $ele = $(this), str = $ele.html(), progress = 0;
$ele.html('');
var timer = setInterval(function() {
var current = str.substr(progress, 1);
if (current == '<') {
progress = str.indexOf('>', progress) + 1;
} else {
progress++;
}
$ele.html(str.substring(0, progress) + (progress & 1 ? '_' : ''));
if (progress >= str.length) {
clearInterval(timer);
}
}, 75);
};
})(jQuery);
使用方法 : $("#code").typewriter();
