我之前说我对JavaScript不擅长,我对HTML和CSS很擅长,但在高级CSS上略显灰暗。有没有一种方法可以在换页上做到这一点。这个代码全部都是单个页面,并且不会从服务器重新加载,所以我无法通过页面加载设置事件。加载是通过JavaScript完成的。对于现场演示,您可以到这里:徽标更改网站
我看到你在页面上加载jQuery,这很好,因为它使得这个任务变得简单;)
就在< / body>
之前< script type =text / javascript> ('click',function(){
$('#img-logo')。
$(document).ready(function(){
$('。navigation li')。 ).css('width','212px');
$('#img-logo')。css('height','70px');
});
} );
< / script>
然后更改您的html:
< img src =http://yakko.cs.wmich.edu/~brain/SAS/images/logo.pngalt =logoid =img-logo/ >
你可以在这里找到jsfiddle:

你可以添加一些如果你想要
确保使用一个好的图像(在普通视图中是双倍大小),否则你会看到模糊缩放。
I am using a template that I bought offline that uses JavaScript. I am not that great with JavaScript and I would like to make it so that the logo goes from being small to larger as soon as the user clicks on one of the links above example:

As I said before I am not good at JavaScript, I am fairly good at HTML and CSS, but stil a little grey on advanced CSS. Is there a way I can do this on page change. The code for this is all one single page and does not reload from server so I can't set an event via "page load". The loading is done via JavaScript. For a live demo you can go here: Logo Change Site
I see you load jQuery on your page, that's good because it makes this task simple ;)
just before </body>
<script type="text/javascript">
$(document).ready(function(){
$('.navigation li').on('click', function(){
$('#img-logo').css('width','212px');
$('#img-logo').css('height','70px');
});
});
</script>
then change your html:
<img src="http://yakko.cs.wmich.edu/~brain/SAS/images/logo.png" alt="logo" id="img-logo"/>
you can find jsfiddle here:
http://jsfiddle.net/arqjn/
you can add some effects on css-transition if u want
make sure to use a good image (double-sized on normal view) or you will see blur on zoom
