推荐答案
Fiddle:http://jsfiddle.net/82AsF/(点击导航栏中的主题下拉菜单)
给你的链接一个类theme-link
和一个data-theme
主题名称的值,如下所示:
Fiddle:http://jsfiddle.net/82AsF/ (click the themes dropdown in the navbar)
Give your links a class theme-link
and a data-theme
value of the theme name like so:
<a href="#" data-theme="amelia" class="theme-link">Amelia</a>
然后,在全局变量中定义您的主题,如下所示:
Then, define your themes in a global variable like so:
var themes = {
"default": "//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css",
"amelia" : "//bootswatch.com/amelia/bootstrap.min.css",
"cerulean" : "//bootswatch.com/cerulean/bootstrap.min.css",
"cosmo" : "//bootswatch.com/cosmo/bootstrap.min.css",
"cyborg" : "//bootswatch.com/cyborg/bootstrap.min.css",
"flatly" : "//bootswatch.com/flatly/bootstrap.min.css",
"journal" : "//bootswatch.com/journal/bootstrap.min.css",
"readable" : "//bootswatch.com/readable/bootstrap.min.css",
"simplex" : "//bootswatch.com/simplex/bootstrap.min.css",
"slate" : "//bootswatch.com/slate/bootstrap.min.css",
"spacelab" : "//bootswatch.com/spacelab/bootstrap.min.css",
"united" : "//bootswatch.com/united/bootstrap.min.css"
}
(当您这样做时,请将这些 bootswatch css 文件托管在您自己的服务器上 - 我只是盗链,因为我手头没有服务器)
然后,使用以下 jQuery 代码:
(please host these bootswatch css files on your own server when you do this - I'm only hotlinking because I don't have a server on hand)
Then, use the following jQuery code:
$(function(){
var themesheet = $('<link href="'+themes['default']+'" rel="stylesheet" />');
themesheet.appendTo('head');
$('.theme-link').click(function(){
var themeurl = themes[$(this).attr('data-theme')];
themesheet.attr('href',themeurl);
});
});
