代码如下
这是一个自定闪烁打印文字的Jquery特效
HTML代码如下:
<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代码:
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);
}
调用方法:
<script type="text/javascript">
$(function () {
typewriter("code");
});
</script>
下面开始对js代码进行Jquery插件封装了
(function ($) {
$.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);
调用方法:
<script type="text/javascript">
$(function () {
$("#code").typewriter();
});
</script>
封装完毕!
