我根据我在Codepen中的需求定制了这段代码,它就像一个魅力。由于我更喜欢使用Jsfiddle,我只是将完全相同的代码(HTML,CSS和JS)复制并粘贴到Jsfiddle界面中,但它不起作用。

var TxtRotate = function(el, toRotate, period) {
"use strict";
this.toRotate = toRotate;
this.el = el;
this.loopNum = 0;
this.period = parseInt(period, 10) || 2000;
this.txt = '';
this.tick();
this.isDeleting = true;
};
TxtRotate.prototype.tick = function() {
"use strict";
var i = this.loopNum % this.toRotate.length;
var fullTxt = this.toRotate[i];
if (this.isDeleting) {
this.txt = fullTxt.substring(0, this.txt.length - 1);
} else {
this.txt = fullTxt.substring(0, this.txt.length + 1);
}
this.el.innerHTML = '<span class="wrap">'+this.txt+'</span>';
var that = this;
var delta = 150 - Math.random() * 100;
if (this.isDeleting) { delta /= 2; }
if (!this.isDeleting && this.txt === fullTxt) {
delta = this.period;
this.isDeleting = true;
} else if (this.isDeleting && this.txt === '') {
this.isDeleting = false;
this.loopNum++;
delta = 500;
}
setTimeout(function() {
that.tick();
}, delta);
};
window.onload = function() {
"use strict";
var elements = document.getElementsByClassName('txt-rotate');
for (var i=0; i<elements.length; i++) {
var toRotate = elements[i].getAttribute('data-rotate');
var period = elements[i].getAttribute('data-period');
if (toRotate) {
new TxtRotate(elements[i], JSON.parse(toRotate), period);
}
}
// INJECT CSS
var css = document.createElement("style");
css.type = "text/css";
css.innerHTML = ".txt-rotate > .wrap { border-right: 0.08em solid white }";
document.body.appendChild(css);
};
在我的网站上,它也不起作用。我不熟悉JS,所以我需要帮助解决这个问题。
谢谢!
