0 | 16638 | 将字体图标添加到我们的按钮中 |
Description
.svg
的文件格式中的矢量图。这些图标就和字体一样,不仅能通过像素单位指定他们的大小,它们也同样会继承父级 HTML 元素的字体大小。
你可以将 Font Awesome 图标库添加至任何一个 app 中,方法很简单,只需要在你的 HTML 头部增加下列代码即可:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css" integrity="sha384-XdYbMnZ/QjLh6iI4ogqCTaIjrFk87ip+ekIjefZch0Y+PvJ8CDYtEs1ipDmPorQ+" crossorigin="anonymous">
不过在这里,我们已经预先为此页面添加了上述代码。
i
元素起初用于让其它元素具有斜体(italic)的效果,不过现在一般用于指代图标。你可以把 Font Awesome 中的 class 属性添加到 i 元素中,让它变成一个图标,比如:
<i class="fas fa-info-circle"></i>
记住 span
元素也一样可以用于指代图标。
Instructions
thumbs-up
图标到你的 like 按钮上,具体方法是给 i 元素添加 class 属性 fas
和 fa-thumbs-up
;确保你的 "Like" 文本在图标旁边。
Tests
tests:
- text: 增加一个 class 为 <code>fas</code> 和 <code>fa-thumbs-up</code> 的 <code>i</code> 元素。
testString: assert($("i").is(".fas.fa-thumbs-up") || $("span").is(".fas.fa-thumbs-up"));
- text: <code>fa-thumbs-up</code> 图标应该放在 Like 按钮中。
testString: assert(($("i.fa-thumbs-up").parent().text().match(/Like/gi) && $(".btn-primary > i").is(".fas.fa-thumbs-up")) || ($("span.fa-thumbs-up").parent().text().match(/Like/gi) && $(".btn-primary > span").is(".fas.fa-thumbs-up")));
- text: 将 <code>i</code> 元素放置在你的 <code>button</code> 元素中。
testString: assert($("button").children("i").length > 0 || $("button").children("span").length > 0);
- text: 确保你的图标元素有一个闭合标签。
testString: assert(code.match(/<\/i>|<\/span>/g));
