使用JS

Question

我非常接近我网站的完美打字机效果-很大程度上要感谢您在此处出色的输入支持！我正在寻找的是打字机效果的细微变化，如下所示：使文本的最后一行保留在屏幕上而不是被擦除（但是，按照另一篇文章的说明，不是整个文本，只有最后一行）

因此，理想情况下，第一行将建立起来，然后被擦除，然后第二行将建立起来，然后也被擦除，然后最后，第三行将建立起来并保留在屏幕上（同时光标仍然继续闪烁）。如果您能帮助我找出此修改，我将非常感激！预先感谢您一百万！

PS：如果也有可能添加DELAY，那么第一行会在例如5秒钟（仅光标闪烁），这将是锦上添花！ ：-）

PPS：这是link to the original code：

consoleText(['Hello World.', 'Console Text', 'Made with Love.'], 'text',['tomato','rebeccapurple','lightblue']);
function consoleText(words, id, colors) {
if (colors === undefined) colors = ['#fff'];
var visible = true;
var con = document.getElementById('console');
var letterCount = 1;
var x = 1;
var waiting = false;
var target = document.getElementById(id)
target.setAttribute('style', 'color:' + colors[0])
window.setInterval(function() {
if (letterCount === 0 && waiting === false) {
  waiting = true;
  target.innerHTML = words[0].substring(0, letterCount)
  window.setTimeout(function() {
    var usedColor = colors.shift();
    colors.push(usedColor);
    var usedWord = words.shift();
    words.push(usedWord);
    x = 1;
    target.setAttribute('style', 'color:' + colors[0])
    letterCount += x;
    waiting = false;
  }, 1000)
} else if (letterCount === words[0].length + 1 && waiting === false) {
  waiting = true;
  window.setTimeout(function() {
    x = -1;
    letterCount += x;
    waiting = false;
  }, 1000)
} else if (waiting === false) {
  target.innerHTML = words[0].substring(0, letterCount)
  letterCount += x;
}
}, 120)
  window.setInterval(function() {
if (visible === true) {
  con.className = 'console-underscore hidden'
  visible = false;

} else {
  con.className = 'console-underscore'

  visible = true;
}
}, 400)
}

这是我的看法：

// function([string1, string2], target id, [color1,color2], initial pause, final pause)    
 consoleText(['Hello World.', 'Console Text', 'Made with Love.'], 'text',['tomato','rebeccapurple','lightblue'], 5000, 500000);

function consoleText(words, id, colors, initialPause, finalPause) {
  if (colors === undefined) colors = ['#fff'];
  var visible = true;
  var con = document.getElementById('console');
  var letterCount = 1;
  var x = 1;
  var initialCount = 0;
  var waiting = false;
  var target = document.getElementById(id);
  var justStarted = true;
  target.setAttribute('style', 'color:' + colors[0]);
  window.setInterval(function() {
    if(initialCount < initialPause){
      initialCount += 120;
    } else if (letterCount === 0 && waiting === false) {
      waiting = true;
      target.innerHTML = words[0].substring(0, letterCount);
      window.setTimeout(function() {
        var usedColor = colors.shift();
        var usedWord = words.shift();
        x = 1;
        target.setAttribute('style', 'color:' + colors[0]);
        letterCount += x;
        waiting = false;
      }, 1000);
    } else if (letterCount === words[0].length + 1 && waiting === false) {
      waiting = true;
      window.setTimeout(function() {
        x = -1;
        letterCount += x;
        waiting = false;
      }, words.length === 1 ? finalPause : 1000);
    } else if (waiting === false) {
      target.innerHTML = words[0].substring(0, letterCount);
      letterCount += x;
    }
  }, 120);
  window.setInterval(function() {
    if (visible === true) {
      con.className = 'console-underscore hidden';
      visible = false;

    } else {
      con.className = 'console-underscore';

      visible = true;
    }
  }, 400);
}
