--description--
可以通過 jQuery 改變元素開始和結束標籤之間的文本。 甚至改變 HTML 標籤。
jQuery 有一個 .html()
函數,能用其在標籤裏添加 HTML 標籤和文本, 函數提供的內容將完全替換之前標籤的內容。
下面是重寫並強調標題文本的代碼:
$("h3").html("<em>jQuery Playground</em>");
jQuery 還有一個類似的函數 .text()
,可以在不添加標籤的前提下改變標籤內的文本。 換句話說,這個函數不會評估傳遞給它的任何 HTML 標記,而是將其視爲要替換現有內容的文本。
給 id 爲 target4
的按鈕的文本添加強調效果。
查看這篇關於 <em> 的文章來了解更多 <i>
和 <em>
的區別和用法。
注意,<i>
標籤雖然傳統上用來強調文本,但此後常用作圖標的標籤。 <em>
標籤作爲強調標籤現在已被廣泛接受。 可以使用任意一種完成這個挑戰。
--hints--
應該通過添加 HTML 標籤強調 target4
按鈕中的文本。
assert.isTrue(
/<em>|<i>\s*#target4\s*<\/em>|<\/i>/gi.test($('#target4').html())
);
文本應該保持不變。
assert($('#target4') && $('#target4').text().trim() === '#target4');
不應該改變其它任何文本內容。
assert.isFalse(/<em>|<i>/gi.test($('h3').html()));
應該使用 .html()
方法而不是 .text()
方法。
assert(code.match(/\.html\(/g));
應該使用 jQuery 選取 button id="target4"
。
assert(code.match(/\$\(\s*?(\"|\')#target4(\"|\')\s*?\)\.html\(/));
