Question

我想知道是否有人可以帮助完成这项任务;我发现这个伟大的代码每日报价，我只想在每日报价和报价作者之间设置换行符。我想也许创建一个二维数组会让它更容易，但不幸的是我无法弄清楚如何放置换行符。谢谢。这是迄今为止的代码：

<script type="text/JavaScript"> 

var quote = new Array()
for (i=0; i<7; i++){
quote[i] = new Array(6)
}

quote[0][0] = 'If you want to go fast go alone, if you want to go far go together!'; 
quote[0][1] = 'African Proverb';
quote[1][0] = 'We either make ourselves happy or miserable. The amount of work is the same.'; 
quote[1][1] = 'Carlos Castaneda'; 
quote[2][0] = 'Everything should be made as simple as possible, but not any simpler.'; 
quote[2][1] = 'Albert Einstein';
quote[3][0] = 'Failure is the mother of success.'; 
quote[3][1] = 'Chinese Proverb'; 
quote[4][0] = 'The first to apologize is the bravest. The first to forgive is the strongest. The first to forget is the happiest.' 
quote[4][1] = 'Unknown';
quote[5][0] = 'If an egg is broken by an outside force, life ends. If it is broken by an inside force life begins. Great things happen from the inside.'; 
quote[5][1] = 'Unknown';
quote[6][0] = 'Simplicity is the ultimate sophistication.' 
quote[6][1] = 'Leonardo Da Vinci';

var qlen = quote.length;
var firstDate = new Date(2016,2,25);//start date (yyyy,m,d) - m=0=January, m=1=February
var today = new Date();//today
var dif = Math.floor((today-firstDate)/1000/60/60/24);//difference in days
while(dif>=qlen){//calculate the index of the quote of the day 
dif=dif-qlen;//restart the array index if the difference is greater that the    array's length 
} 
var todayQuote = quote[dif][0];//the quote of the day 
var todayQuoteOwner = quote[dif][1];//author of the quote of the day

onload = function(){document.getElementById('q').firstChild.data = todayQuote + </n>  + document.getElementById('qu').firstChild.data = todayQuoteOwner}


</script> 

<div>  id='q'; </div>

我建议首先将<script></script>内容移到最后而不是开头，这样就不需要onload函数了。

您的javascript也引用了qu元素，但您的html代码未包含该元素。暂时我会假设它只是另一个div，但如果我错了，请随时纠正我。

您的javascript似乎也将引用和作者设置为firstChild.data，但html div中没有任何子项。因此，如果您实际运行此操作，则会出现空错误，因此我已为每个错误添加了嵌套<p />。为了测试，我还包括innerHTML，以便您可以看到结果。

<div id="q"><p></p></div>
<div id="qu"><p></p></div>

<script type="text/JavaScript">
    // ... generate the quotes and authors ...
    var qElement = document.getElementById('q');
    var quElement = document.getElementById('qu');

    qElement.firstChild.innerHTML = qElement.firstChild.data = todayQuote;
    quElement.firstChild.innerHTML = quElement.firstChild.data = todayQuoteOwner;
</script>

如果您希望为引号和作者提供一个元素容器，那么只需完全删除qu元素，并用< br/>元素分隔这两个部分。

<div id="q"><p></p></div>

<script type="text/JavaScript">
    // ... generate the quotes and authors ...
    var qElement = document.getElementById('q');

    qElement.firstChild.innerHTML = qElement.firstChild.data = todayQuote + '<br/>' + todayQuoteOwner;
</script>
