使用jquery在时间之后更改标题词

Question

我想为我网站上的标题字设置动画，每隔4秒更改一次文字。该结构应该是这样的：＆＃34; XY＆＃34; ＆安培; ＆＃34; ZZ＆＃34;，其中XY和ZZ成为不同的单词，连接器＆＃34;＆amp;＆＃34;总是保持在同一个位置。

我看到了这种效果here。

你会怎么做呢？

这就是我所拥有的：

    $(document).ready(function(){
   setTimeout(function(){
    $(".maintext1").fadeOut(function() {
    $(this).html("beautiful ").fadeIn();
      });
    $(".maintext2").fadeOut(function() {
    $(this).html(" responsive").fadeIn();
      });     
}, 4000);
 });

更改＆＃34;简单＆＃34;中的单词＆安培; ＆＃34;清洁＆＃34;到美丽＆＃34; ＆安培; ＆＃34;响应＆＃34 ;.

但是我如何迭代特定的单词列表呢？ 让我们说：

1. 简单＆amp;清洁
2. 美丽＆amp;响应
3. 动画＆amp;效果
4. less＆amp;更

然后又回到1.

Answer 1

无需重新发明轮子。

要获得您链接到的页面上显示的确切效果，请使用下面显示的他们的方法（直接从该网站提取，而不是我的工作）

有两点需要注意：

1. 那里可能有一些你不需要的CSS，可能想检查一下
2. 以下功能取决于underscore.js

Answer 2

所以我明白了。花了一段时间，它可能不是最好的解决方案。但它完全符合我的要求。

HTML

<div class="header-words">
  <ul class="header-words__inner">
    <li class="first-word">simple</li>
    <li class="word-connector">&amp;</li>
    <li class="second-word">clean</li>
  </ul>
</div>

jquery

<script>
$(document).ready(function(){
    var text = ['fast', 'modern', 'beautiful'];
    var text2 = ['easy', 'classic', 'responsive'];    
        i = 0,
        $word1 = $('.first-word');
        $word2 = $('.second-word');

    setInterval(function ()
    {
        $word1.fadeOut(function () {
            $word1.text(text[i % text.length]).fadeIn();
        });
        $word2.fadeOut(function () {
            $word2.text(text2[i++ % text2.length]).fadeIn();
        });
    }, 4000);
});
</script>

如果有人有更好的解决方案，我会很高兴听到！

Answer 3

这样的事情会起作用：

$(function()
{
  var setTitle = function()
  {
    var title = Math.random().toFixed(2) + ' & ' + Math.random().toFixed(2);
    $('title').html(title);
  };

  setInterval(setTitle, 4000);
});

根据需要更改标题变量。 http://www.w3schools.com/jsref/met_win_setinterval.asp
