使用 QUnit 测试 hover CSS 属性
Test hover CSS properties using QUnit
我想使用 QUnit 进行一个简单的测试,以检查元素悬停时的 CSS 属性。
假设我有一个 link,CSS 定义为
a:hover {text-decoration: none}
我试图让 QUnit 触发鼠标悬停事件,然后检查 link 的 CSS 是什么,但它不起作用。但是,当我手动悬停 link 时,测试给出了正确的结果。
这是 QUnit 代码
QUnit.test('hover test', function() {
$('a').mouseover(function (){
QUnit.ok($('a').css('text-decoration') == 'none');
});
$('a').mouseover();
}
你不能,因为它不是受信任的事件。
Events that are generated by the user agent, either as a result of
user interaction, or as a direct result of changes to the DOM, are
trusted by the user agent with privileges that are not afforded to
events generated by script through the
DocumentEvent.createEvent("Event") method, modified using the
Event.initEvent() method, or dispatched via the
EventTarget.dispatchEvent() method. The isTrusted attribute of trusted
events has a value of true, while untrusted events have a isTrusted
attribute value of false.
Most untrusted events should not trigger default actions, with the
exception of click or DOMActivate events.
然而,您可以根据您的 :hover 样式创建一个新的 class,然后在 mouseover/mouseleave 上切换 class。
