Question

I’ve seen some tutorials that look like someone is typing to display the lesson.

I can’t remember where I’ve seen it, but what would be the JavaScript snippet to do that?

I’m sure it would be based upon a simple setInterval method, but I thought I would ask you in case you knew of a really good one.

Answer 1

This is what you want?! You need a DIV with the id “typeText” in your html.

var theText = "myText",
progress = 0,
speed = 250;

window.setInterval(function(){
    document.getElementById("typeText").innerHTML = theText.substring(0, progress);
    progress++;
}, speed);
