如何动态更改html背景 [英] how to change html background dynamically
问题描述
body
{
background：＃000000 url（images / back_all.gif）repeat-x top;
字体：12px Tahoma，Arial，Helvetica，sans-serif;
颜色：＃666666;
}
我有一个javascript，它会在window.onload之后加载并导致页面要扩大正面意义，所以我的其余部分将变黑。
如何在JavaScript代码完成后再次将背景图片应用于我的页面？
jQuery：
$（'body'）。css（'backgroundImage'，'url（something.gif）'）;
非jQuery：
分配正文ID：< body id =the_body>
document.getElementById（'the_body'）。style.backgroundImage =something.gif
或as John提到
document.body.style.backgroundImage =something.gif;
此外，T POPs提到，确保它在最后：
< ; HTML>
< body>
.....数据........
< script type =text / javascript>
....代码........
< / script>
< / body>
< / html>
I have a page which has a style like this in a css file:
body
{
background: #000000 url(images/back_all.gif) repeat-x top;
font: 12px Tahoma, Arial, Helvetica, sans-serif;
color: #666666;
}
and I have either a javascript which is loaded after window.onload and causes page to be expand vericaly and so the rest of my page will become black. how can I apply the background image to my page again after the javascript code is completed?
jQuery:
$('body').css('backgroundImage', 'url(something.gif)');
Non-jQuery:
Assign Body an ID: <body id="the_body">
document.getElementById('the_body').style.backgroundImage = "something.gif"
or as John mentioned
document.body.style.backgroundImage = "something.gif";
and furthermore, a T POPs Mentioned, make sure it goes at the end:
<html>
<body>
..... Data ........
<script type="text/javascript">
.... Code ........
</script>
</body>
</html>
