[英]Div will not display when using an array
Trying to randomly generate one div from an array on each load of a page. 尝试在每次页面加载时从数组随机生成一个div。
I've managed to put together bits from a few random image generators to create the below. 我设法将一些随机图像生成器中的位组合在一起以创建以下内容。
When the [0] in the array contains an image, like the rest, everything works as it should. 当数组中的[0]包含图像时,就像其余图像一样,一切都会正常进行。 Once I replace [0]'s image with a div or video, nothing at all displays and the page is blank.
将[0]的图像替换为div或视频后,什么都没有显示,并且页面空白。
Any suggestions where I'm going wrong? 有什么建议我要去哪里吗?
<link rel="stylesheet" type="text/css" href="style.css" >
<script type="text/javascript">
function random()
{
video = new Array(4);
video[0] = "<div class="clip"> </div> ";
video[1] = "<a href=''><img src='http://lorempixel.com/output/city-q-c-640-480-3.jpg' alt='' /></a>";
video[2] = "<a href=''><img src='http://lorempixel.com/output/fashion-q-c-640-480-6.jpg' alt='' />";
video[3] = "<a href=''><img src='http://lorempixel.com/output/technics-q-c-640-480-1.jpg' alt='' />";
for(var i = 0; i < video.length; i++)
{
index = Math.floor(Math.random() * video.length);
document.write(video[index]);
}
}
</script>
</head>
<body>
<script type="text/javascript">
random();
</script>
</body>
You need to escape your quotes. 您需要转义报价。 Try:
尝试:
video[0] = "<div class=\\"clip\\"> </div>";
or use singles: 或使用单打:
video[0] = "<div class='clip'> </div>";
Also, you are aware your div is empty, right? 另外,您知道自己的div是空的,对吗? Unless your style does something to make it display something, it will appear blank.
除非您的样式能够使其显示某些内容,否则它将显示为空白。
