当您悬停列表项时,此演示不会添加类.
This demo does not add class when you hover a list item.
我在这里做错了什么?
$("li").hover(
function () {
$(this).addClass('hover);
},
function () {
$(this).removeClass("hover");
}
);
html
<ul>
<li>Milk</li>
<li>Bread</li>
<li>Chips</li>
<li>Socks</li>
</ul>
css
.hover{
color:green;
font-size: 20px;
}
提前致谢.
您的 JavaScript 格式错误:
Your JavaScript was badly formed:
$("li").hover(
function () {
$(this).addClass('hover);
},
function () {
$(this).removeClass("hover");
}
);
应该是:
$("li").hover(
function () {
$(this).addClass('hover');
},
function () {
$(this).removeClass('hover');
}
);
如果您单击屏幕顶部的 JS Lint
按钮,它会告诉您这一点(这不是批评,只是一个注意供您将来使用 JS Fiddle).
If you click on the JS Lint
button to the top of the screen it would've told you this (this isn't intended as a criticism, just a note for your future use of JS Fiddle).
