remove css hover style
提问by James Radford
I have mark up that toggles the hover css style using this rule. When there's a checkbox inside the panel I want to remove the background image style. Is this possible? I've tried the following although it fails.
我已标记使用此规则切换悬停 css 样式。当面板中有一个复选框时，我想删除背景图像样式。这可能吗？虽然失败了，但我已经尝试了以下方法。
CSS:
CSS：
.StaffMode .day ul li.standard a:hover table {
background:url("test.png");
}
JS:
JS：
$("li.test table li").hover(
function () {
if($(this).children(':checked')) {
alert('need to remove the background image style'); // shows as expected
$(this).children('a').removeClass('hover'); // this doesnt work?
}
}
);

What you need to do is put some restriction on your :hoverrule, and have your JavaScript change the element so it no longer applies. Something like this:
您需要做的是对您的:hover规则进行一些限制，并让您的 JavaScript 更改元素使其不再适用。像这样的东西：
.has-hover:hover
{
/* do whatever */
}
And then your JavaScript does this:
然后你的 JavaScript 会这样做：
$(this).children('a').removeClass('has-hover');
You can't remove the :hoverbut you can remove the has-hoverclass, and since the rule requires both, this will prevent the .has-hover:hoverrule from being applied.
您不能删除 ，:hover但可以删除has-hover类，并且由于规则需要两者，这将阻止.has-hover:hover应用规则。
