我正在尝试制作一个可以在选中复选框时转为“暗模式”的网站。我已将复选框设置为看起来像一个开关。我让它与一些 javascript 一起工作以加载备用样式表“onChange”。这工作正常,问题是,当您取消选中该框时,我希望它再次加载原始样式表。任何帮助将不胜感激。我是 javascript 的新手,想了解更多。以下是我的 HTML、CSS 和 Javascript 代码:
<input type="checkbox" id="switch1" name="switch1" class="switch" onchange="switch_style('alt');"/>
<label for="switch1">Dark Mode</label>
/* This is for the dark mode switch */
input.switch:empty
{
margin-left: -999px;
}
input.switch:empty ~ label
{
position: relative;
float: left;
line-height: 1.6em;
text-indent: 4em;
margin: 0.2em 0;
cursor: pointer;
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
}
input.switch:empty ~ label:before,
input.switch:empty ~ label:after
{
position: absolute;
display: block;
top: 0;
bottom: 0;
left: 0;
content: ' ';
width: 3.6em;
background-color: #c33;
border-radius: 0.3em;
box-shadow: inset 0 0.2em 0 rgba(0,0,0,0.3);
-webkit-transition: all 100ms ease-in;
transition: all 100ms ease-in;
}
input.switch:empty ~ label:after
{
width: 1.4em;
top: 0.1em;
bottom: 0.1em;
margin-left: 0.1em;
background-color: #fff;
border-radius: 0.15em;
box-shadow: inset 0 -0.2em 0 rgba(0,0,0,0.2);
}
input.switch:checked ~ label:before
{
background-color: #393;
}
input.switch:checked ~ label:after
{
margin-left: 2em;
}

}
set_cookie( style_cookie_name, css_title,

}
}
function set_style_from_cookie()
{
var css_title = get_cookie( style_cookie_name );
if (css_title.length) {
switch_style( css_title );
}
}
function set_cookie ( cookie_name, cookie_value,
lifespan_in_days, valid_domain )
{
// http://www.thesitewizard.com/javascripts/cookies.shtml
var domain_string = valid_domain ?
("; domain=" + valid_domain) : '' ;
document.cookie = cookie_name +
"=" + encodeURIComponent( cookie_value ) +
"; max-age=" + 60 * 60 *
24 * lifespan_in_days +
"; path=/" + domain_string ;
}
function get_cookie ( cookie_name )
{
// http://www.thesitewizard.com/javascripts/cookies.shtml
var cookie_string = document.cookie ;
if (cookie_string.length != 0) {
var cookie_value = cookie_string.match (
'(^|;)[\s]*' +
cookie_name +
'=([^;]*)' );
return decodeURIComponent ( cookie_value[2] ) ;
}
return '' ;
}
最佳答案
试试这个解决方法:
对于“Dar Mode”css,在每个选择器之前添加 dark-mode
类。
即,
.dark-mode input { }
.dark-mode input.switch:empty ~ label { }
等...
然后在您的 JS 中,只需为主体切换类“暗模式”。 我认为那样可能更有效。
