【问题描述】:
我在我的主页上插入了一个简单的打字机动画,代码来自这里,只对 HTML 进行了少量编辑以个性化内容。
https://codepen.io/hi-im-si/pen/DHoup。
<h5>
<body>Hi! My name is Kritika. I am</body>
<a="" class="typewrite" data-period="2000" data-type='[ "designer.", "a creative.", "a storyteller.", "an entrepreneur." ]'>
<span class="wrap"></span>
</a>
</h5>
<style>
body {
text-align: left;
text-color:#ce3635;
margin-top:25%;
}
</style>
<script>
var TxtType = function(el, toRotate, period) {
this.toRotate = toRotate;
this.el = el;
this.loopNum = 0;
this.period = parseInt(period, 10) || 2000;
this.txt = '';
this.tick();
this.isDeleting = false;
};
TxtType.prototype.tick = function() {
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 = 200 - 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() {
var elements = document.getElementsByClassName('typewrite');
for (var i=0; i<elements.length; i++) {
var toRotate = elements[i].getAttribute('data-type');
var period = elements[i].getAttribute('data-period');
if (toRotate) {
new TxtType(elements[i], JSON.parse(toRotate), period);
}
}
// INJECT CSS
var css = document.createElement("style");
css.type = "text/css";
css.innerHTML = ".typewrite > .wrap { border-right: 0.08em solid #fff}";
document.body.appendChild(css);
};
</script>
当我第一次登陆网站时,它会循环工作。但在那之后,如果我转到网站内的另一个页面,然后按返回按钮、主页图标或主页标签按钮返回主页,动画将停止工作。 (注意 - 切换到另一个选项卡并返回网站根本不会影响动画。)
另外,我无法让动画文本以我想要的颜色显示。
我是编码新手。任何帮助将不胜感激。谢谢!
