javascript - 如何使用javascript在动画中换行？

标签 javascript html css

我正在尝试实现打字机动画，以便在我使用的行之间留出空格

function splitLetters(word) {
  var content = word.innerHTML;
  word.innerHTML ='';
  var letters = [];
  for (var i = 0; i < content.length; i++) {
    var letter = document.createElement('span');
    letter.className = 'letter';
    var char = content.charAt(i);
    letter.innerHTML = char===" "?"&nbsp;":char;
    word.appendChild(letter);
    letters.push(letter);
  }

  wordArray.push(letters);
}

letter.innerHTML = char===" "?" ":char;

以同样的方式我想给出换行符而不是   以及可能的方法？

假设我想显示一行

great web developer

现在我想让它以这种格式显示

great web
developer

great 和 web 之间的空格和开发人员之前的换行符。

任何帮助将不胜感激。 我也不希望单词像 wonderful 一样被吐成两个词。

var words = document.getElementsByClassName('word');
var wordArray = [];
var currentWord = 0;


for (var i = 0; i < words.length; i++) {
  splitLetters(words[i]);
}

function changeWord() {
  var cw = wordArray[currentWord];
  var nw = currentWord == words.length-1 ? wordArray[0] : wordArray[currentWord+1];
  for (var i = 0; i < cw.length; i++) {
    animateLetterOut(cw, i);
  }

  for (var i = 0; i < nw.length; i++) {
    nw[i].className = 'letter behind';
    nw[0].parentElement.style.opacity = 1;
    animateLetterIn(nw, i);
  }

  currentWord = (currentWord == wordArray.length-1) ? 0 : currentWord+1;
}

function animateLetterOut(cw, i) {
  setTimeout(function() {
		cw[i].className = 'letter out';
  }, i*80);

最佳答案

一个简单的方法是插入一个 <br>标记而不是 span .您可以对所有空间执行此操作，如下所示:

var words = document.getElementsByClassName('word');
var wordArray = [];
var currentWord = 0;


for (var i = 0; i < words.length; i++) {
  splitLetters(words[i]);
}

function changeWord() {
  var cw = wordArray[currentWord];
  var nw = currentWord == words.length-1 ? wordArray[0] : wordArray[currentWord+1];
  for (var i = 0; i < cw.length; i++) {
    animateLetterOut(cw, i);
  }

  for (var i = 0; i < nw.length; i++) {
    nw[i].className = 'letter behind';
    nw[0].parentElement.style.opacity = 1;
    animateLetterIn(nw, i);
  }

  currentWord = (currentWord == wordArray.length-1) ? 0 : currentWord+1;
}

function animateLetterOut(cw, i) {
  setTimeout(function() {
		cw[i].className = 'letter out';
  }, i*80);
}

function animateLetterIn(nw, i) {
  setTimeout(function() {
		nw[i].className = 'letter in';
  }, 340+(i*80));
}

function splitLetters(word) {
  var content = word.innerHTML;
  word.innerHTML ='';
  var letters = [];
  for (var i = 0; i < content.length; i++) {
    var letter = document.createElement('span');
    letter.className = 'letter';
    var char = content.charAt(i);
    if(char === " ")
        letter = document.createElement('br');
    else
        letter.innerHTML = char;
    word.appendChild(letter);
    letters.push(letter);
  }

  wordArray.push(letters);
}

changeWord();
