阻止循環

Question

對不起，這可能不僅僅是你們所有人的簡單事情，而是在嘗試了幾件事情之後，我離我想要的很遠。

我只是想在第一次運行之後停止該動畫： CSS typewriter

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); 
    }; 

感謝您的幫助！

你好（goedemorgen）vloryan，

如果你想所有的句子/字被動畫後停止動畫，然後簡單地改變

if (typeof dataText[i] == 'undefined'){ 
    setTimeout(function() { 
     StartTextAnimation(0); 
    }, 500); 
} 

要

if (typeof dataText[i] == 'undefined'){ 
    return false; 
} 

什麼這是，如果計數器到達單詞/句子數組的末尾（因爲i未定義），它將返回false並停止。
