JavaScript animation error

Question

Hi! :)

I tried to make an JS typewriting animation but in my first attempt to see the output I got the Uncaught ReferenceError. If anyone could help me solve this out I would be grateful.

THE CODE:

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(toRotae), period);
}
}

//CSS part

var css = document.createElement("style");
css.type = "text/css";
css.innerHTML = ".typewrite > .wrap { border-right: 0.08em solid #12937F}";
document.body.appendChild(css)

};

Answer 1

The first function has a semicolon after the closing bracket.

Answer 2

Uncaught ReferenceError: (TxTtype) is not defined
Line: 11.
You need to look at line 1 and line 11 to resolve this problem. Then line 54.

btw, you should put the h1, a, and span tags in the body of the document, not the head.

Answer 3

Guys thank you a lot! I managed to solve it and works just fine.

You definetly gave me an inspiration! :) until later
